FDA Clears Biotrue ONEday Contact Lenses
The U.S. Food and Drug Administration has cleared Biotrue ONEday, Bausch + Lomb's new daily disposable contact lens. The newly approved CL is made from a substance that the company calls HyperGel, that reportedly combines the best features of conventional hydrogels and silicone hydrogels. The lens offers high water content and delivers more oxygen than a traditional hydrogel – all without the need for silicone – while maintaining the comfort of conventional hydrogels. The CLs also provide consistent, clear, comfortable vision throughout the day because the innovative, bio-inspired material helps them retain moisture and optical shape even after hours of wear. The lenses contain 78 percent water, the same water content as the cornea, and deliver the oxygen level needed by the open eye to maintain healthy, white eyes. The outer surface of the lens is designed to mimic the lipid layer of tear film to prevent dehydration. Read more.
