Types of Contact Lenses and Eye Care 

principle and types of contact lenses 

There are several types of contact lenses with regard to the function they perform over vision. They can be corrective, cosmetic, cosmetic corrective and therapeutics, which treat vision problems such as keratoconus. In relation to the material, they are divided between rigid gas-permeable contact lenses and the gelatinous contact lenses. In relation to the time of use, contact lenses can be disposable and also reusable. Choosing the best lens as well as the most suitable brand for each patient is a process that necessarily depends on an investigation done by the ophthalmologist physician. He is the appropriate professional to make the best adaptation, aiming to ensure that the patient both comfort and optimal eye health.

Because they are almost imperceptible, contact lenses bring more comfort to working, playing sports or any other activity where glasses can get in the way. Placed directly on the surface of the eyes to correct vision, contact lenses can be used to correct vision problems over long or short distances (myopia, farsightedness and astigmatism) and also age-related vision problems (presbyopia). The principle of contact lenses is the same as glasses: they divert the light and redirect it to your retina to give you a clearer view.
