People can’t leave digital products, while exposed to digital screens for long
time, our eyes and
health
will be harmed continuously. To filter the harmful blue light, anti blue lenses
can effectively
block the
blue light from digital screens and provide us comfort when confronting digital
products.
Progressive Lenses
Progressive lenses allows you to see close-up, middle-distance and distance
without needing to
change
your
glasses. With progressive lenses, it's clear to see your computer screen or
other objects at
arm's
length.
What's more, compared to bifocal lenses, there is no line signed on the
progressive lenses.
Photochromic Lenses
Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors
and darken
automatically
when exposed to sunlight. They can shield your eyes from 100 percent of the
sun's harmful UVA
and
UVB rays.
