Contact Lenses Vancouver, WA
A contact lens, often referred to as simply, a contact, is a small, thin lens placed directly on top of the eye. Contacts are a medical device that is worn to correct vision, or is sometimes used for cosmetic or therapeutic reasons. Contacts are preferred by some for both aesthetic and practical reasons. They are visually invisible and do not get wet from conditions such as sweat, rain, or condensation, making them more comfortable for some. Additionally, there are specific eye conditions in which contacts are recommended over glasses including keratoconus and aniseikonia.
What forms of Contacts are available?
There are three forms of Contacts that are commonly used.
Soft LensGenerally considered more comfortable, soft lens allow for better oxygen permeability and lens wetability which our eyes need. Some have even been approved for overnight wearing. Soft Lens are available in both disposable and non-disposable varieties. Disposable contacts have been found to reduce chance of infection and decrease your time of caring for them. Non-disposable contacts are used when you require a specific customization that is not standard.
The disadvantage of Soft Contact Lens is their ability to take in pollutants. Because of their high oxygen permeability, patients with allergies find that those allergens are still causing discomfort to their eyes.
