Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight. An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun's harmful UVA and UVB rays. It's a good idea to consider photochromic lenses for children's eyewear as well as for eyeglasses for adults Because a person's lifetime exposure to sunlight and UV radiation has been associated with cataracts later in life.
Blue light blocking glasses are made with lenses that block or filterout harmful blue rays that emit from computer screens on phones, laptops, computer screens and tablet screens. The lenses keep your eyes protected from glare and potentially reduce eye health problems the retina sustains during prolong exposure to blue light.
This lens also has an anti-electromagnetic radiation surface coating. This invisible barrier filters out 100% electromagnetic radiation waves and does not produce static electricity. This in turn offers even more protection for the eyes.
They are not polarized.
