Evolution of photochromic lenses

Thirty years after Corning invented color-changing glass lenses, another company has carried forward the color-changing glass lenses --Transitions Optical. In 1991, it became the first company to commercially manufacture resin color-changing lenses. Since its inception, the company has been a joint venture between PPG Industries (51%) and Essilor (49%). In April 2014, Essilor acquired a 51% stake in PPG. At present, the mainstream is resin photochromic lenses.

The correct method for lens cleaning

Wet it with water first, and then add a little detergent or hand sanitizer to each lens. Dip your fingers to the back of the lens, and then scrub with your fingers. Be careful not to use too much force to prevent the lens from being worn out by grit.

The key here is to rinse. First of all, never use hot water, because hot water will cause the lens to expand due to heat, which will crack the film in the resin lens.

Finally, you should rinse with cold water, do not wipe with a cloth, because any glasses cloth or suede can not perfectly wipe the lens, even the more you wipe it, the more indistinct it gets. If there is hard dust in the cloth, it will scratch the lens.
