Has your optometrist recommended transition lenses?\u00a0<\/b><\/h2>\n

Your optometrist may have referred to transition lenses as photochromic lenses, or maybe even light-adaptive lenses, or variable tint lenses. All of these names refer to the same type of lens.<\/p>\n

Transition lenses are eyeglasses that are designed to be clear for indoor use and automatically darken when exposed to sunlight or UV light.<\/b><\/p>\n

With their unique design, transition lenses may eliminate the need for sunglasses<\/a> and are therefore convenient for those who wear glasses full time.<\/p>\n

Transition lenses are also trusted to provide 100 percent UVA and UVB protection when they are both clear and dark.<\/p>\n

How do transition lenses work?<\/b><\/p>\n

When transition lenses are exposed to the sun\u2019s ultraviolet (UV) rays, the molecules inside the lens become activated, causing them to automatically darken. Since UV rays are able to penetrate through the clouds, not only do transition lenses darken on bright sunny days, but also when the sky is cloudy and overcast.<\/p>\n

Transition lenses automatically adjust their color according to the light and UV intensity in the environment.<\/p>\n
