Prescription lenses: when to use

Vision correction is a delicate and complex process that requires considerable work and the attention of specialists to achieve a result. But technology doesn’t stand still, and today you can often see prescription or custom lenses among ophthalmologists’ prescripts. Let’s see what it is and in what cases we should use them.

When to use prescription lenses

Creating prescription lenses is a time-consuming process, but necessary in the following cases:

• At high degrees of myopia and hypermetropia. Traditionally, for the treatment of such diseases, prism glasses are used, the lenses of which work like prisms. However, they may have side effects: image distortion, increased eye fatigue, etc. Prescription lenses allow you to achieve the performance of prism glasses while eliminating the disadvantages of a prism. In addition, they are thinner in design, which makes them more comfortable for everyday use.

• To solve this problem, you should use cylindrical lenses. Their task is to increase or decrease the refraction of light in a specific meridian. But a healing tool can also have the opposite effect. For example, many patients complain about the distortion of the shapes and colors of objects due to glasses. And the use of prescription lenses helps to avoid such inconveniences.

• Traditional correction doesn’t always give the desired result in this case, but prescription lenses significantly increase the chances of success due to specific production technology.

• With non-standard parameters of the distance between the pupils’ centers and (or) nasal bridge. The use of ready-made glasses in such situations leads to peripheral distortion of the image and pupils not falling into the optical center of the lens, so their effectiveness will be minimal.

• If you need to use diameters smaller or larger than standard, this allows you to use a wide range of diopters.

• When complex correction is required.

Prescription lenses are spectacle glasses that are manufactured in a wide range of diameters and have high refractive power. They can be tinted, or photochromic. Custom prescription lenses are suitable for people who need complex vision correction.

How to choose the best frame for prescription lenses

Visually impaired people often wonder how to improve their vision and protect their eyes from sunlight. The need for optics that combines both functions arises in many situations: in sunny weather in the city, on vacation, during sports, and is especially acute when driving a car. Moreover, experts tirelessly say sunglasses are not just an accessory for beauty and comfort. You should protect your eyes well from bright sunlight and UV light. Otherwise, we may face various severe diseases with age. Among which are cataracts and some types of cancer. There are a lot of options for combining sunglasses with prescription lenses.

Frame and lens compatibility

Be aware that frames and lenses may not be compatible with each other.

Familiarize yourself with the main nuances that affect the compatibility of lenses and frames.

Full-rim frame

The rim design of frames is perhaps the most reliable and versatile. Full-rim frames are more varied in shape, style, materials, and decor than other types. They are suitable for men, women, and children.

Full-rim frames are the best choice if you need glasses with different lenses for each eye. The fact is that different lens weights can lead to spectacles distortion on one side. If you use a thick frame, then it will correct the weight balance.

If you are using mineral glass lenses or fairly thick resin lenses, you will also fit only full-rim frames.

Half-rim frame

In half-rim frames, fixing lines replace part of the structure. Such ones have a very spectacular design but are somewhat limited in functionality.

Half-rim frames are only been used in combination with polymer lenses since. It’s problematic to fasten heavy glasses with a fishing line securely.

Rimless frame

Rimless frames always look elegant and stylish. They are less visible on the face. Rimless glasses always win in weight due to the lack of them.

For them, only lightweight polymer lenses are suitable, and it’s best to use reinforced lenses to avoid chipping at the attachment points.

Sunglass overlays

Sunglass overlays are perhaps the easiest and fastest way to add sun protection to your eyeglasses.

There are many types of sunscreens. They don’t always look aesthetically pleasing. There are often difficulties in choosing the appropriate shape and size of the overlay.

Optical manufacturers often produce ready-made sets of frames with sunscreen overlays to solve this problem. The overlays exactly repeat the shape and design of the frame. They attach quickly and conveniently to the front of your spectacles with the help of magnets while keeping them as stylish as they were without the overlay.

What lenses to choose for sunglasses?

Tinted lenses

It’s the most simple and affordable lens option for making prescription sunglasses. Tinted lenses differ in color, degree of light transmission (the darkest ones have 80% tint), and additional functional coatings.

Polarized lenses

Polarizing lenses darken the visible image and filter out the rays of a specific direction. Due to this, you can see the surrounding objects without blinding glare. Few people know that you can easily order polarized prescription glasses with a prescription from an ophthalmologist.

Photochromic lenses

Photochromic lenses are lenses that adapt to light conditions. They are transparent indoors and darken in bright sunlight. Photochromic glasses are very versatile. You can use the same spectacles in any weather.

Photochromic polarized lenses

Glasses that combine photochromic and polarization are the ultimate convenience and an ideal accessory for drivers. These lenses are rare and are more expensive than other lenses. But it is impossible to think of better sun protection than glasses with such lenses.

People with visual impairments who need to correct them don’t always have the opportunity to purchase ready-made sunglasses with diopters because the choice of frames for ready-made glasses is limited. A great way to remedy this inconvenience is to have custom-made sunglasses. You can choose your favorite frame from Ossa Frames extensive range and enter the necessary details of your lens prescription.

Prescription sunglasses: what you need to know

Sunglasses are a significant way to protect your eyes and ensure clear and comfortable vision on sunny days. In addition to temporary loss of vision, sunlight can cause long-term damage to the eyes. The UV radiation from the sun can also cause sunburn to the eyes and lead to serious illness over time.

For prescription eyeglass wearers, sun protection is available in several options, including prescription sunglasses, photochromic lenses, or clip-on sunglasses. The best solution depends on your personal preferences, comfort, and which option best suits your lifestyle.

Prescription sunglasses are available for almost all vision prescriptions, including farsightedness, nearsightedness, astigmatism, bifocals, and progressive lenses. You can wear any sunglasses with prescription lenses as long as the shape of the lens doesn’t distort vision. So if you like the new designer sunglasses, you should have no problem fitting prescription lenses into the frames in most cases.

There is a large selection now. You can purchase prescription sun lenses in various materials and coatings, including polarized lenses (for glare protection), tinted lenses, anti-scratch coatings, and many more.

Prescription sunglasses are a great solution when you prefer not to wear contact lenses or feel dry or irritated eyes (during allergy season or in dusty or sandy areas), when you are going to swim or when you simply don’t want to use contact lenses. They give you another option for comfort, safety, and excellent vision.

Who needs prescription sunglasses?

For those who need vision correction, for any medical conditions, and are also exposed to significant sunlight, prescription sunglasses are what you need.

Benefits of Prescription Sunglasses

There are many benefits associated with prescription sunglasses. Let’s look at them.

UV protection

Eye exposure to UV rays can cause such diseases as cataracts, macular degeneration, and corneal injury. The risk has increased, given the ongoing rampant climate change.

Prescription sunglasses come with a protective UV coating applied to the lenses. The coating blocks UV rays from reaching the eyes. Make sure they provide both UVA and UVB coverage when purchasing prescription sunglasses. The combination of both of these coatings provides almost 100% UV protection.

Clarity of vision

Since these sunglasses are also available by prescription, providing clear vision is one of their most important features. If you suffer from nearsightedness or farsightedness or any other condition that can be corrected with prescription glasses, you can also rely on prescription sunglasses.

Glare prevention

Glare is very common in bright sunlight conditions. It happens when light rays are reflected from the surface of the lens. Glare can be reduced to negligible levels by applying an anti-reflective coating to prescription sunglasses.

Protection of the skin around the eyes

The skin around our eyes is very sensitive. Exposure to the sun, even for a short time, can have a devastating effect on this part of the face. You should wear sunscreen at all times. While outdoors, by pairing it with sunglasses, you can provide an extra layer of protection to the sensitive part of your face.

Serves as a fashion accessory

Sunglasses have long been considered a fashion accessory. You can wear them for all occasions, and they suit every mood.

Prescription lenses for everyone

Maintaining the eyes’ health and protecting them from the adverse environment is significant in our time. Taking care of your eyesight is easy now. After all, the choice of glasses is so great that everyone will choose the right ones for themselves, considering their characteristics.

Main differences between prescription glasses and contact lenses

Glasses provide more benefits than contact lenses. They don’t require special care and cleaning. In addition, there is no need to touch the eyes just to put them on, thus reducing the risk of eye infections. Glasses are also more affordable in the long run, as they don’t need to be changed so often.

Prescription glasses offer more benefits than contact lenses.

In addition, glasses can do things that contact lenses cannot. Glasses can adjust the amount of light entering the eye for optimal vision and comfort. Photochromic lenses, to be precise, are transparent indoors at night. They can also automatically darken in the sun for comfortable, clear vision in any light. While some contact lenses can block some UV rays from entering your eyes, photochromic eyeglass lenses can block 100% of UV rays and protect the inside of your eyes and the eyelids and outer part of your eyes.
Glasses also serve as an extension of your character and personality and make the perfect fashion statement.

Benefits of prescription glasses

• Wearing glasses reduces the need to touch your eyes and, as a result, reduces the chance of developing eye infections or eye irritation.
• If you have sensitive or dry eyes, glasses will not make the problem worse than contact lenses.
• In general, prescription glasses are more affordable than contact lenses.
• There is no need to change glasses as often, except, of course, accidentally broken ones. If there is ever a prescription change over time, you can keep the current frames and replace only the lenses.
• Frames can also be trendy and say a lot about your style and personality.
• Glasses protect against various environmental factors such as debris, dust, and wind.

How to understand your eyeglass prescription?

If you looked at your recipe, you must have wondered what these numbers and symbols mean. Some of the recipes may be for long-distance viewing, the others for reading, office, or progressive lenses.

Date of prescription

The duration of the prescription is not strictly defined. Its relevance depends on many factors, such as your age, the degree of the underlying visual impairment, the presence of concomitant disorders, the course and nature of common diseases, and the use of certain medicines. Doctors recommend checking the eyesight and the relevance of the prescription at least once a year. If you have a prescription but don’t wear glasses according to it for more than 3 months, then before ordering glasses, it’s advisable to clarify your vision parameters again.

Basic parameters and their interpretation

1. OD and OS – right and left eye

Each recipe starts with this parameter. It is the designation of the right and left eyes in Latin, where O means oculus, that is, “eye”, D – dexter (“right”), and S – sinister (“left”). Thus it is:

• OD – right eye;

• OS – left eye.

Sometimes, instead of Latin designations, English ones are used – R (that is, right) for the right eye and L (left) for the left.

2. SPH – sphere

The SPH parameter indicates the optical power. They measure these indicators in diopters.

Here is the type of lens. The doctor prescribes scattering lenses, that is, minus lenses, with myopia. A “-” sign precedes the number in this case. You need converging lenses for farsightedness. They are marked with a “+” sign in the prescription.

3. CYL – cylinder

The doctor writes CYL parameters in cases where the patient has astigmatism. Then he is prescribed special cylindrical lenses, and the numbers in the prescription indicate the optical power of the cylinder. If there is a minus in front of the numbers, glasses correct myopic astigmatism. If plus – for hypermetropic astigmatism. It is also possible to correct mixed astigmatism. Then the prescription will contain both a minus and a plus.

4. AX-axis

AX, that is, Axis, in Latin means “axis”. This parameter indicates the position of the cylinder axis. They mark it in degrees – from 0 to 180. It is filled in only if the doctor recommends glasses with astigmatic lenses to the patient.

5. Pr – prism

The doctor prescribes prismatic glasses in cases where the patient has a binocular vision violation. They need lenses with prisms for strabismus most often.

Specialists indicate optical power in diopters.

6. PD – pupillary distance

It denotes the distance between the pupils’ centers. They measure this parameter in millimeters. When ordering lenses with a complex design, PD is prescribed separately for each eye.

7. ADD – addition

The added factor is considered when creating glasses with several optical zones – for work at close, medium, and long distances.

Addition indicates the diopter difference between these zones. For example, diopters are indicated for correcting vision at long distances. To find out what diopters are needed for correction at close distances, add the additional factor.

Now you know how to decipher a prescription for glasses or lenses. However, remember that doctors recommend confirming or updating the recipe periodically. Vision may change, especially if your work involves prolonged computer use or small details. Age-related changes can also affect eyesight after 40 years. Doctors recommend undergoing an annual check-up with an ophthalmologist.

Prescription lenses: Detailed guide

Lenses are the basic element of corrective glasses. They provide high clarity of visual perception of objects. A prescription for lenses is written by an ophthalmologist depending on the pathology of the vision.

You can buy glasses with lenses of the following types:

1. Scattering. Designed to correct myopia.

2. Gatherers. Correct farsightedness. The optical power has a positive indicator.

3. Aspherical. They are used to correct vision for astigmatism. The front side of the lens is spherical, the back side is cylindrical.

Eyeglasses that correct these disorders are equipped with monofocal lenses. That is, they have one focus.

4. Bifocal lenses. have multidirectional diopters and help to see objects at a great distance at the same time and distinguish those nearby. With lenses of this type, you don’t have to purchase two pairs of glasses – for distance and reading. However, there is a sharp boundary between the far and near zone, and because of this, some patients experience tangible inconvenience.

Individual lenses

With the best custom lenses, you can experience true freedom of vision! After all, individual lenses are created taking into account all personal needs. In their manufacture, individual parameters of the fit of the frame, the features of the recipe, and visual needs are taken into account. They can be either single vision or progressive.

Progressive lenses

1. For permanent wear

Progressive lenses allow people over the age of 40 to use the same glasses to work at different distances. Today it is the most modern way to correct age-related farsightedness.

2. For work (office)

Glasses with special lenses for near and intermediate vision are suitable not only for office work but also become a real lifesaver for many professions. Musicians, architects, teachers – in many cases, these glasses can be a great alternative to reading glasses.

3. Sports lenses (for curved frames)

Made specifically for installation in frames that have a sports (curved) shape. Also, these lenses are suitable for installation in sunglasses with a large bend. Sports lenses are made from super strong polymers.

4. Photochromic lenses

Photochromic lenses are lenses that automatically adapt to any light level. In the sun, such lenses darken and brighten indoors. Thus, photochromic glasses provide stress-free vision, including without annoying glare.

5. Lenses for drivers

Special single vision or progressive lenses provide the high-quality vision you need for driving at night and in bad weather conditions:

• make it easier to look at different distances,

• improve spatial orientation,

• provide a correct estimate of distances,

• clarity of color recognition.

Coatings and filters

1. Protective multifunctional coatings

Various special coatings are applied to the surface of polymer lenses to improve their consumer properties. Such coatings:

• increase the resistance of the lens surface to scratching;

• eliminate glare and false images on the lens surface;

• give the surface of the spectacle lens antistatic, water, and dirt-repellent properties.

2. Mirror coatings

• In the city and on the beach – fashionable mirror coatings will emphasize your individuality in any situation. You can choose different colors.

3. Toning

Coloring can be:

Monochromatic – lenses are evenly tinted in one color.

• Gradient – the color of the lenses gradually changes from the darkest shade to the lightest, from top to bottom.

• Two-tone – the lenses are painted simultaneously in two colors, one either smoothly transitions into the other, or contrasts sharply with it. This is a rather bold and outrageous decision, aimed primarily at creating a certain image. Two-tone tinting does not bring practical benefit to vision, however, it doesn’t pose any harm.

At the stage of choosing glasses, it’s recommended to immediately share your wishes and lifestyle features with a specialist. A qualified ophthalmologist will tell you what options should be added for more comfortable use of glasses.

In addition, it’s better to select lenses based on the results of an eye examination. A prescription can become outdated over time, so it’s best to confirm it when ordering new glasses.

Pupillary distance: what need to know

Pupillary distance (PD) is the distance between your pupils that determines comfort and how well your glasses fit. Having a PD is just as considerable as your prescription when it comes to ordering a new pair of prescription glasses or sunglasses. The average value of the pupillary distance for an adult is about 63 mm.

After all, measurements can vary widely – between 51 mm and 74.5 mm for women and 53 mm and 77 mm for men. There are two main methods of PD measurement: single PD and dual PD.

Single PD is the pupil-to-pupil measurement between each eye. Double PD is the measurement from the nasal bridge to each eye.

Double PD is considered the most accurate. PD is especially important when fitting glasses with progressive lenses, which require precise alignment of the lens with the pupil to ensure comfortable vision at all distances.

Can you measure it yourself?

You can measure the pupillary distance yourself. For this, you need a millimeter ruler and a mirror. If there is no ruler, you can print a particular scale for measurement, but you first ensure that the printer doesn’t distort the scale.

The room should be well lit. Stand in front of the mirror at a distance of 20 cm. Locate the ruler above the eyeballs, parallel to the eyebrow line. Held the head straight to obtain more accurate measurements.

First, you should close one eye and place zero on the ruler opposite the left center of the pupil. The more precisely the center is determined, the better the result is.

Next, you should open the second eye and find the division on the ruler, which will be accurate in the middle of the pupil. At this time, you can’t move your head or the ruler. Direct eyes to the mirror for the measurement to be correct. The obtained data in millimeters is the pupillary distance. You should make measurements 3 or 4 times.

Another person’s help

You can measure with the help of another person. Following simple rules, you can understand how to measure the pupillary distance with an assistant. For this, it’s necessary to face each other. The distance between people should be 20 cm. A larger or smaller interval will distort the result.

The measured person should look over the assistant’s head. The head should be lower than the eyes of the subject. Look at an object that is at a distance of 3-6 meters from a person. For the accuracy of the measurement, you can’t move, move your head and turn your eyes. You should fix the view. You should position the ruler above the eyes parallel to the eyebrow line. Zero should be set in the center of the pupil of one eye and determine at what distance the other pupil will be.

Examination by an ophthalmologist

Measuring the pupillary distance at an ophthalmologist will show a more accurate result. Choosing glasses, the doctor holds a special ruler at different intervals. It depends on the degree of nearsightedness or farsightedness.


Ophthalmologists use a pupillometer to determine the diameter of the pupils and the distance between them. The modern device is rich in settings and guarantees the high accuracy of the result. Compared to other methods, the pupillometer has the following advantages:

• quick and accurate result;

• accuracy is not affected by uncontrolled movements of the pupils and the degree of illumination of the office;

• the result is displayed on the device display.

The device can measure from the nasal bridge to each pupil. It shows data for asymmetry, farsightedness, and myopia. The ability to measure the pupillary distance helps to adjust it when using optical devices. Some of them require settings to see the images.

Transition lenses and prescription sunglasses: main advantages, disadvantages, and differences

Transition lenses 

Glasses with transition lenses change their color, adjusting to the lighting conditions: in bright light, they darken, and in a dark room they remain transparent. This effect is ensured by a special coating with photochromic properties. It is they react to UV, activating their protective properties and reducing light transmission. The degree of darkening of such lenses in some models reaches 85%.

Glasses with transition lenses combine the benefits of corrective and sun protection optics. This is very convenient for people with low vision who can’t protect their eyes on a sunny day because they have to wear corrective glasses. Also, transition lenses are recommended for people who suffer from eye diseases. 


Main advantages 

• “Two in one” – glasses with transition lenses make life easier for people who need vision correction. You no longer need to squint from the sun or wear sunglasses to the detriment of good visibility. Transition lenses provide both the necessary correction and protection from bright sunlight.

• Help for people with eye diseases and photosensitivity – transition lenses provide relief for people who suffer from diseases that cause increased sensitivity to light. Glasses that quickly adapt to changes in lighting effectively protect the eyes from pain and discomfort. 

• Special lenses for drivers – glasses with such lenses react not only to UV radiation but also to visible light, due to which the lenses darken even when not directly exposed to the sun.

Main disadvantages

• The degree and speed of darkening depend on the ambient temperature. The reaction is faster in warm weather and slower in cold weather. At temperatures above 30 °C, the lenses don’t darken completely, but by 90-95%, which can cause discomfort to residents of the southern regions. In the cold, on the contrary, the glasses give out their maximum, which is not always convenient when it is partly cloudy or walking through the forest with constantly changing lighting.

• Limited range of colors – unlike sun-protection and tinted optics, transition lenses have a small palette of possible dimming colors. 

• If you leave your glasses in an enclosed space in hot weather in direct sunlight in a car or on a window, the protective coating may be damaged.

Prescription sunglasses  

Most people who wear glasses often experience discomfort with the onset of sunny weather. This problem is especially true for people who drive a car or spend a lot of time outdoors. An excellent summer solution for people with low vision will be sunglasses with prescription lenses. These are glasses two in one: glasses for vision and sunglasses at the same time. In addition to providing a comfortable stay in the blinding sun, such glasses protect against harmful UV radiation and have several other advantages.

Why do we need prescription sunglasses if there are transition ones?

It would seem, that why would someone need a half solution if there is a complex one? But there are a few subtleties that you need to be aware of to make an informed decision.

• As mentioned above, transition lenses have residual tint. Not everyone likes it. Many people need the most transparent lenses.

• Not everyone is comfortable waiting for the lenses to darken / clear.

• Well, and most importantly, prescription sunglasses have much more options for colors, shades, tints, color combinations, and so on.

Prescription lenses that make you look younger

How to look younger with prescription lenses


Nowadays, glasses are not just an essential item for those with low vision. They have turned into a fashion accessory that can visually make its owner a few years younger or, on the contrary, add age.

We have made a selection of life hacks on how to choose the right glasses to refresh your image and look a few years younger.

Let’s start by choosing the right frame



Frames made of black plastic is the standard of style. Black color is a sign of taste and elegance. It’s both universal and fresh. Suitable for any wardrobe and event, whether it’s weekdays or going to a social event. Wearing black-framed glasses, you will be irresistible. Look great with gray and dark blue frames. Cold black and blue color give gray hair a particular charm.


The form 

Round or rounded frame shapes are most appropriate to hide the signs of age. They soften sharp and sharpened features; fill the face with an inner radiance. The magic of round shapes is that they are good for men and women of any age! Another secret to success is in the shape of a butterfly frame or a cat’s eye. Rounded lines combined with raised corners on the outside of the frames create a lifting effect. 

Tortoiseshell frames

Round tortoiseshell frames are truly a timeless classic. This is the safest spectacle option that women of elegant age can only make. This style of frame is popular with all age groups, making it easy to adapt. Such glasses, although they look very heavy, allow you to emphasize your femininity and give a more youthful look. 

Let’s move on to lenses


Light tinted lenses 

Another way to cover up the skin around the eyes is to choose lenses with a light tint. There are truly magical shades that make the skin younger and radiate with warm natural light. Toning can be full or with a gradient (light at the bottom and dark at the top). These glasses look very aesthetic.


Additional advice: what frames are contraindicated


Great care should be taken when choosing thin metal frames, even if they seem to fit perfectly. The thing is that they are “invisible”, their glasses are transparent, and this means that all wrinkles will be visible. You shouldn’t buy thin wire frames, they will not hide anything, but on the contrary, they will give out the age of a woman. Rimless square glasses are also considered unsuitable. They only add stiffness to the face.

At Ossa Frames, there’s plenty to choose from – and don’t worry about your prescription when it comes to picking your perfect pair, as all our frames that make you look younger are available with custom lenses. When it comes to helping you reach your style potential, we have got you covered. So, choose your fave styles – Right Now!

Reasons to buy prescription lenses

What you should know about prescription lenses

It’s worth noting that only correctly selected glasses can provide good visual acuity and excellent style. Whereas incorrectly chosen optics can cause discomfort. That is why it’s so significant to choose prescription lenses.

Prescriptions are important because they help determine the strength of your lenses, which ones are best for your eyes, and, to some extent, which frames you can wear. They vary depending on each person’s vision needs, lifestyle, and eye health. 


How do prescription lenses work?

Prescription lenses work to correct your vision and are designed to alter the direction of light rays so that they shine correctly on your retina, allowing you to see properly. The way they alter the direction of light varies based on whether you are near or farsighted.

Let’s look at the Top 5 reasons why you should buy prescription lenses:


1. Diagnostics and analysis of vision for the correct selection of lenses 

The first step before buying glasses is a comprehensive eye examination. This will give you an up-to-date scenario and also help identify any eye health issues. The ophthalmologist not only prescribes the right lenses for your vision or its impairment but also performs a comprehensive eye examination. For example, conditions such as dry eyes and cataracts may be the cause of vision problems.


2. Having problems with vision, such as nearsightedness or farsightedness

If you are nearsighted, your eyes overfocus and this causes light rays to focus in before it reaches the retina, instead of focusing directly on it. Prescription lenses diverge the light rays so that the eyes don’t focus so much on it, allowing the light rays to reach the retina where they belong.

For people with farsightedness, the eyes don’t focus well, and as such, light rays don’t form a point before reaching the retina. Prescription lenses help to increase the eyes’ focusing power so that the light reaches a point by the time it reaches the retina, allowing it to correctly see images.


3. Choosing the right frames and lenses for your specific needs and lifestyle 

Not every type of frame is suitable for every type of lens. For example, some prescriptions call for very thick lenses which means that a lightweight wire frame is not the best option. You can choose the right frame for your type of lens, which will be the right decision and make your glasses convenient and comfortable to use.


4. Variety of lens types – how to find the perfect fit  

There are hundreds or even thousands of different lens types, often tailored to individual needs such as driving or reading, and your ophthalmologist can help you find the right one for your needs. There are 5 main types of lenses but they will have many options.

Standard plastic lenses usually with an anti-scratch coating included.

Aspherical lenses are thinner and flatter, which reduces the cosmetic appearance of “big eyes” if you are farsighted, or “small eyes” if you are nearsighted.

Polycarbonate lenses are impact-resistant and used for goggles, children, and sports glasses, providing good UV protection.

High index lenses are thinner and lighter than standard ones. They may benefit people with stronger prescriptions who might otherwise have heavier, thicker lenses.

Lenses for the office. These lenses provide comfortable vision and are ideal for those who may experience eye strain symptoms at the end of a hard day’s work.


5. The need for specialized lenses 

Sometimes prismatic lenses, progressive lenses, and other special items may be required. Specialty lenses need facial measurements to ensure that the frame is properly positioned and that the lenses fit correctly in the glasses. Frames and lenses are designed according to the different parameters of your eyes. Your ophthalmologist will take measurements (such as optical centers), discuss with you the required reading distance or zone, and look at the slope of the frame to your face.
