People who have trouble wearing regular contact lenses may have better luck with larger lenses that continuously bathe the eye with saline. Scleral lenses are a type of gas-permeable lens that are larger than traditional small-diameter contact lenses. “Scleral lenses provide better vision and comfort than small-diameter gas-permeable contact lenses,” says Melissa Barnett, an optometrist with the UC Davis Eye Center and a co-author of the study.
