For the best vision, comfort and appearance when wearing bifocals and trifocals, ask your optician about anti-reflective (AR) coating. In addition to eliminating distracting reflections, AR coating allows more visible light to enter the eye for night driving, and it makes the bifocal and trifocal lines in segmented multifocal lenses less visible because it reduces the amount of light reflecting off these junction lines.
Also, if you are sensitive to sunlight outdoors or spend a good deal of your day going in and out of the sun, ask your eye care professional about photochromic lenses. These light-sensitive lenses are clear indoors and quickly darken in response to sunlight to reduce glare. Photochromic lens technology is available in all multifocal lens designs, including lined bifocals and trifocals.
