The first contact lens that darkens automatically when exposed to bright light has received FDA approval. The lenses have the same technology as eyeglasses that darken in sunlight.
Sold as Acuvue Oasys Contact Lenses with Transitions Light Intelligent Technology, the soft lenses are indicated for daily use for people with myopia or hyperopia whose eyes are disease-free. People with certain degrees of astigmatism also can use the lenses.
