How to maintain a vision for many years

The eyes are a significant and vulnerable organ. During human life, the load on the eyes increases. If you don’t give the eyes due attention, then over time, vision becomes worse, and characteristic diseases appear.

There are a few simple rules following which you can protect your eyes from the aggressive effects of external factors. It will help maintain eye health and prevent the development of characteristic diseases.

Let’s rest our eyes

In today’s world, we can’t completely give up work or recreation related to the use of gadgets. But it’s important to remember that prolonged exposure to their screens can lead to the development of dry eyes, fatigue, and even myopia. So try to follow the 20-20 rule: every 20 minutes, take a 20-second break during which you look at something located at a distance of 5-6 meters from you.

Wear sunglasses

And not only in summer: as soon as the sun gets bright enough, you should think about your glasses: ultraviolet affects the retina of the eyes as dangerously as it does to the skin. And it can even lead to the development of melanoma. Therefore, don’t neglect glasses and wear them even on cloudy days because ultraviolet can damage your eyes even in cloudy weather.

Keep your distance

When working with a phone or reading text from an e-book or tablet, don’t forget to keep the gadget at the maximum safe distance for vision – ideally, it shouldn’t be less than 30 cm. The closer your eyes are to the blue light emitted by phones and tablets, the more they are dangerous.

Get an annual eye exam

A comprehensive eye examination can determine your risk of eye diseases. It also helps ensure that your eyeglasses or contact lenses prescription is up to date and, as far as possible, you see clearly and are not in danger.

Special meals

People with impaired vision need to eat foods that strengthen the vessels of the eye retina: blueberries, black currants, and carrots. Cod liver, greens: parsley, lettuce, dill, and green onions should be in the diet of myopic. The fruits of rose hips (infusion, decoction) and cranberries help with eye dystrophy.

Eye strain protection

Take breaks while working at your computer. Try to take a 15-minute break every 2 hours while working at the computer. Let your eyes rest every 20 minutes by looking away from the screen and around.

Work in good light. Your eyes need enough light to read, write, work on a computer or watch TV. In poor lighting and in the dark, the eyes have to concentrate more, which leads to visual strain.

Use suitable glasses or lenses. If you wear glasses or contact lenses, it’s important that they always fit your eyes and the type of work you do.

Maintain good air quality. Keep your eyes moisturized and improve your vision by using a humidifier; create a comfortable temperature, and avoid smoke and other pollutants.

How to protect your eyes while working at a computer

1. Comfortable lighting. It’s better to equip the workplace to the left or right of the window to let daylight fall on the monitor from the side. Placing the monitor opposite or in front of a window is uncomfortable and puts excessive strain on the eyes. There should not be images of different brightness in the field of view, so it’s better to close the windows with curtains or blinds. If you can’t place the table the way you want, you can purchase an anti-glare screen.

2. Artificial lighting should be uniform and sufficient. You can’t work on the monitor by the light of table lamps alone. Indirect diffused light should be used, which doesn’t give reflections on the screen.

3. Place the screen so that your eyes are level with the top edge of the screen. Better to tilt the monitor to place the bottom is closer to you than the top. It will make the level of inclination of the visual axis optimal.

4. Keep the screen clean, and rub it from dust and dirt with special wipes that don’t leave streaks.

5. If you work with glasses, clean your lenses regularly with a soft cloth. It’s better to order particular glasses with a protective coating from the adverse effects of the radiation of a flickering screen. If you have normal vision, you can book glasses without diopters.

6. The monitor should be at a distance of 50-60 cm from the eyes. If the font is small and hard to read, select a larger one. Drink plenty of water and don’t forget to blink to keep your eyes moist and prevent them from feeling dry and gritty.

7. Regularly during the working day, do exercises for the eyes every 1-2 hours. They are simple and don’t require much time, allowing you to relax and train the muscles of the eyes.

 

Take care of your vision! Visit an ophthalmologist regularly and follow these simple rules.

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.

Pupilometer

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

 

Color 

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.

Pick a pair of frames online and enter your prescription details. You will soon be rocking a pair of glasses that look great and make everything around you look great as well.
