Contact lenses are used for vision correction and are placed on the cornea of the eye. They do the same curative function that conventional spectacles or glasses do. However, in comparison, they are very light in weight and are, for all purposes, simply undetectable. Contact lenses help form the image on the retina of the eye by either converging or diverging the rays of light that are entering the eye. These have been a boon for individuals with vision disabilities. If you wish to get your eyesight checked for contact lenses, you can visit The Sight Avenue today!
Contact lenses are devices made of medical grade plastic materials used primarily for correction of refractive error. They arrange for a more active spectacle-free life, superior cosmetic acceptability, better and clearer images, lack of misting and a broader arena of view than spectacles. The contact lens clinic at The Sight Avenue offers contact lens trial, fitting and dispensing for cases ranging from simple refractive errors to complex corneal surfaces such as post-transplant eyes and patients with keratoconus.
In the case of normal vision, the light from the object hits the cornea and focuses on the retina. Because of some refractive error, every so often, the light from the object does not focus on the retina, but either in front of it or behind it. To rectify this refractive error, contact lenses are used to focus on the retina. The kind of contact lenses used depends on the category of vision impairment and how much refractive error is involved. How much the lens turns the light to focus on the retina is measured in diopters (D).
