Acuvue Oasys Contact Lenses Current Affairs
The US Food and Drug Administration (FDA) has approved use of Acuvue Oasys Contact Lenses with Transitions Light Intelligent Technology, world’s first contact lens that automatically darkens when exposed to bright light. It is first of its kind contact lens to incorporate same technology that is used in eyeglasses that automatically darken in the sun.
These contact lens are soft contact lenses indicated for daily use to correct vision of people with non-diseased eyes who are nearsighted (myopic) or farsighted (hyperopic). They can be used by people with certain degrees of astigmatism, an abnormal curvature of the eye.
These contact lenses contain photochromic additive that adapts amount of visible light filtered to eye based on amount of ultra-violet (UV) light to which they are exposed. This additive slightly darkens lenses in bright sunlight that automatically return to regular tint when exposed to normal or dark lighting conditions.
