Everything you need to know about contact lenses
Why wear contact lenses?
In some circumstances, contact lenses are more practical and comfortable than glasses.
From a technical point of view, they allow you to widen your field of vision. The correction is applied over the entire surface of the lens. And the latter is placed directly on the cornea so that the eye can enjoy improved vision from all angles.
Practising physical activity, wearing a mask, or going out on a rainy day is not always pleasant when you wear glasses. Indeed, the condensation that forms on the glasses affects vision. Wearing contact lenses eliminates this problem.
Technology, comfort and lenses
Contact lenses at Optical Center are at the cutting edge of technology. Whatever your vision problem, contact lenses can correct it because they have evolved a lot in recent years. This type of optical equipment is an alternative whether you are presbyopic, shortsighted, myopic, or farsighted. And, even if you have several levels of correction on the same eye, it is possible to wear lenses. Some people are sometimes reluctant because of fear regarding the oxygenation of the ocular tissues.

Different types of lenses
Contact lenses are mainly worn for vision correction. However, in some cases, they are prescribed following an operation, an accident or a pathology and must be worn throughout the recovery. In addition, some people use them for aesthetic reasons, such as changing eye colour.
On the optical market, two types of corrective lenses are available, regardless of the reason for wearing the lens:
Rigid lens: it replaces the hard lens. Despite its rigidity, this lens does not prevent good oxygenation of the eyes. Therefore, it is more suitable for people whose ocular humidity is not optimal. Its lifespan is 1 to 2 years, which explains its higher price.
Soft lens: This is the most common due to its ease of use. Several lenses are possible:
– Daily lenses (single use);
– Weekly lenses;
– Monthly or bi-monthly lenses;
– Yearly lenses.
Some soft and hard lenses need to be removed and cleaned every night. Others can be worn day and night.
