SETO 1.56 photochromic progressive lens HMC/SHMC

Short Description:

Photochromic progressive lens is the progressive lens designed with “photochromic molecules” that adapt to varying lighting conditions throughout the day, whether indoors or outdoors. A jump in the amount of light or UV rays activates the lens to turn darker, while little lighting causes the lens to revert back to its clear state.

Product Features

1.The characteristics of photochromic lenses
Photochromic lenses are available in nearly all lens materials and designs, including high indexes , bifocal and progressive. An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun's harmful UVA and UVB rays.
Because a person's lifetime exposure to sunlight and UV radiation has been associated with cataracts later in life, it's a good idea to consider photochromic lenses for children's eyewear as well as for eyeglasses for adults.

2.The Characteristic and Advantange of Progressive Lens
Progressive lens, sometimes called "no-line bifocals," eliminate the visible lines of traditional bifocals and trifocals and hide the fact that you need reading glasses.
The power of progressive lens changes gradually from point to point on the lens surface, providing the correct lens power for seeing objects clearly at virtually any distance.
