Scleral contact lenses

They are rigid gas permeable (RGP) lenses and are large in size. Apart from covering the cornea, they extend to cover a large part of the sclera and the white part of the eye. Scleral contact lenses offer advantages like stability of fit, superb comfort and excellent vision. They are known to be the most comfortable lenses that one can possibly wear as they are made of lighter and breathable materials.

There are mini-sclera contact lenses as well that are larger than the round shaped contact lenses but some white is still visible at the corner of the eyes. The most commonly used sclera contact lenses are the white and black sclera contacts. Both these contact lenses come in many styles. The most widely used ones are those that make the iris, the colored part of the eyes completely disappear.
