Soft contact lenses are used to correct vision for a number of disorders. Indications for wearing lenses are:
- short-sightedness ;
- farsightedness;
- astigmatism (changes in the configuration of the lens and cornea);
- presbyopia (age-related impaired vision).
Advantage of soft contact lenses in front of glasses
The material from which modern soft eye lenses are made - the hydrogel or silicone hydrogel is very plastic, so that they are distributed over the cornea without creating unpleasant sensations. In addition, soft contact lenses of long wearing for 35-80% consist of water, so when a person is awake and blinks occasionally, the cornea of the eye is constantly moistened. Another important property of these devices for correcting vision is air permeability, and since the lens occupies a large part of the cornea, it is very significant that the necessary oxygen enters the eye tissue freely.
For those who still doubt whether to wear a lens or continue to wear glasses, we will note what is the advantage of contact lenses. So the lens:
- Do not reduce visual acuity.
- move together with the pupil.
- provide 100% side vision.
They are convenient to wear in any weather, while glasses can fog, get dirty, etc.
For many, the determining factor for choosing lenses is the ability to lead an active lifestyle without any restrictions, for example, to play sports. Those who do not want to advertise the problems with eyesight, contact lenses should be chosen for the reason that they are almost invisible. And colored and tinted lenses give the iris the desired color.
