Progressive lenses generally cost the most because of their modern design — they do not have the distinct line between the distance vision correction at the top and the near vision correction at the bottom like bifocal lenses do.

This also means that since the UV rays that enter a car are already filtered by the windshield, photochromic eyeglasses will not themselves darken. Very recent advancements in photochromic technology allow some brands of photochromic lenses to activate in both ultraviolet and visible light, so these eyeglasses will turn darker even in a car that has a UV-filtering windshield.

Photochromic lenses work via a chemical reaction in the lenses. They are made with trace amounts of silver chloride. When silver chloride is exposed to ultraviolet light, the silver molecules gain an electron from the chloride to become silver metal.

This gives the lens the ability to absorb visible light, turning darker in the process. The lenses are made out of similar chemical compounds as those used in the development of photographic film. While film exposure is made to be permanent, photochromic lenses are also made with copper chloride, which strips the silver of its chloride electron.

This is what helps the lenses return to their original, non-absorbing state in the absence of ultraviolet light. This method is used in all forms of eyewear that use photochromic lenses, such as high-index lenses, progressive lenses, and bifocals.

I ordered the transition lenses and they get nice and dark. Glasses arrived right on time! Will definitely use again.
