Contact lenses, or therapeutic lenses, are thin lenses that are placed on the surface of the eye. While some wear them for cosmetic reasons, their primary function is to correct and improve vision problems related to refractive errors, act as a protective layer in patients with eye injuries, reduce discomfort or pain associated with refractive and non-refractive errors, and minimize light sensitivity in patients with eyes disorders or injuries to the eye.

Astigmatism is an extremely common eye condition that affects both children and adults. It occurs when there is an imperfection in some part of your cornea, the clear tissue that covers your iris.
