Scleral lenses are a type of contact lens designed to rest on the white part of the eye, known as the sclera, rather than directly on the cornea. They are larger than standard contact lenses and create a tear-filled space between the lens and the cornea, which can help improve vision and comfort for individuals with certain eye conditions. These lenses are often used to treat conditions like keratoconus, dry eye syndrome, and irregular corneas. Because they provide a smooth optical surface, scleral lenses can enhance visual clarity and reduce discomfort, making them a valuable option for those with challenging eye issues.
