Progressive glasses are glasses that allow you to see objects equally clearly at different distances. It’s achieved as follows. The upper part of the lens is designed for distance reading, while the lower part is for reading up close. It’s enough to look down to change the perceived clarity of an image from a far distance to a near one. The middle zone of the lenses doesn’t have a sharp transition and allows you to change the focus gradually without unnecessary discomfort.
Features of the selection of lenses
To use glasses with progressive lenses to be as comfortable as possible, you should choose them correctly. First of all, distance visual acuity is determined. It’s mandatory to find the center distance. As for the design, you can choose a frame depending on your taste and install progressive lenses. Glasses made individually will be more comfortable. Such lenses are more accurate, as all the person's individual characteristics are considered.
The only thing left to add is that progressive lenses, despite positive characteristics, have their contraindications.
First, it’s a diagnosed anisometropia, when the visual acuity in the eyes is different. It’s also impossible to use such glasses for people with strabismus. It’s due to the impossibility of maintaining the parallel movement of the pupil along the zones of progression.
Progressive lenses are not suitable for patients with cataracts due to clouding of the lens and with nystagmus because the pathology disrupts focus and doesn’t provide a direction of view to the desired area.
Progressive lenses are also contraindicated for people with glaucoma and macular degeneration. Other contraindications are diabetes mellitus, thyroid disease, and osteochondrosis with a pronounced vegetative disorder.
Progressive lenses are suitable for:
- who needs to have several pairs of glasses at the same time (far and near);
- who has good vision at one of the distances: far or near, and doesn’t want to take off and put on glasses whenever changing the nature of the activity.
The main feature of progressive lenses is that they allow you to see well at all distances: you can drive a car and look at a map simultaneously, read and watch what is happening around you, play sports, work at a computer, and see the whole world around you. And all this in one glasses!
How to wear glasses with progressive lenses?
Glasses with progressive lenses are the best choice for a person with presbyopia. Thanks to the lens, you will see well at any distance. You can do your usual things with progressive glasses: walking, working, and driving a car.
Progressive glasses are for good vision at various distances.
The lens has several areas. When you look at the top of the lens, you will see objects in the distance. The middle region is intermediate. Looking down, you will see the things in front of you.
Start wearing progressive lenses gradually. You have to get used to the lenses. It will take about a week.
With the advent of new progressive glasses, forget about your old glasses. Adaptation will take 2-3 days or more than a week. It’s better to wear glasses only at home for the first few days. Then you can walk around the store wearing glasses. Then you can take a leisurely walk down the street. When you feel more confident, you can try to move up the stairs.
There are simple exercises for the adaptation period:
- Focus your gaze on an object near you, and then shift it to a big thing far away from you.
- As you move up the stairs, lower your head and look through the middle area of the lens. So you will see a clear picture of the stairs two meters away from you. Gradually increase the exercise time.
- From time to time, don’t turn your head much to the right, then to the left. When turning, fix your gaze on an object to your side. Keep repeating for fifteen to thirty minutes.
Performing the above exercises, you shouldn't have problems with adaptation. If discomfort persists when wearing glasses with progressive lenses, consult an ophthalmologist.
