How Scleral Contact Lenses Work
Different in their design from traditional contact lenses, scleral contact lenses are much larger and sit on a different part of the eye, providing a therapeutic treatment environment that makes it possible to treat a number of issues with the cornea and sclera, including chronic dry eyes.
A scleral contact lens is made from a polymer that is easily permeable by oxygen, and is designed to sit on the whites of your eyes (as opposed to a traditional contact lens, which sits directly on the pupil and cornea). This larger lens leaves a space between the surface of the eye and the lens itself, which is then filled with artificial tears, allowing the eye to be consistently treated and moisturized.
Scleral contact lenses are especially helpful for those with chronically dry eyes that can’t handle normal contact lenses, which can sometimes cause extra burning and irritation, when dry eyes are already present.
