According to the American Adademy of Ophthalmlogy, the United States FDA has approved Johnson & Johnson’s new light-adaptive contact lenses. These lenses include a photochromic filter that adjusts to the amount of light entering the eye. Therefore these lenses automatically darken in bright sunlight and return to a more regular tint in nomal light.
These soft lenses are appropriate for healthy individuals with myopia or hyperopia, and those with certain degrees of astigmatism. Each disposable lens can be worn daily for up to two weeks. However, Dr. Koster warns that while the lenses appear to filter blue light and block UV rays, they are not a subsitute for sunglasses because they do not completely cover the eye.
