scleral lenses are a type of contact lens that are larger than standard lenses. They are designed to rest on the white part of the eye, called the sclera, and create a tear-filled vault over the cornea. This design helps to provide comfort and improved vision for people with irregular corneas or conditions like keratoconus. These lenses can also be beneficial for individuals with dry eyes or those who have had eye surgeries. Because they cover a larger area, scleral lenses can help protect the cornea and maintain moisture, making them a popular choice for those with specific eye care needs.
