With progressive lenses, you can look up to see clearly across the room and in the distance. You can also look ahead to view your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably.
And it's easy to adapt to progressive lenses.
And progressive lenses eliminate an annoying problem caused by bifocal and trifocal lenses known as "image jump." With conventional bifocals and trifocals, images seem to "jump" as your eyes move past the sharply defined boundary between the distance and near parts of the lens.
Photochromic lenses have many molecules embedded in them. These molecules are transparent to visible light when in the absence of UV light, so the lenses will be light. When in the presence of UV rays, the molecules react and change shape. When this happens the molecules absorb some of the visible light causing the lens to darken. The brighter the sunlight the darker the lens.
If you wear eyeglasses and wear sunglasses when outside, you are forced to carry two pair of eyewear. For most people this is a hassle. You either break the pair you are carrying or lose them. If you choose to wear photochromics, you can wear them for eyeglasses and sunglasses. You simply buy the photochromic sunglasses.
Photochromic sunglasses are great for motorcycle riding sunglasses as well. So many motorcyclists are forced to carry two or even three pairs of sunglasses or goggles or interchangeable lens kits with clear, charcoal and amber color lenses. With photochromic lenses you can buy and carry just one pair of sunglasses or goggles for all day and even night riding. With photochromic lenses you do not have to pull off the side of the interstate endangering your life and maybe others to change your sunglasses or goggles. You can ride from morning to night without ever having to change your eyewear.
