Photochromic:
NXT is the most advanced photochromic sun lens material ever made,
creating lenses like our 24:7 Original and Contrast with a broad
transmission range, rapid activation and exceptional durability. Both
new 24:7 lenses darken and fade in a hurry, and they keep on changing
after other brands' photochromic films stop working. 24:7 lenses in
NXT® are also virtually shatterproof, with a lifetime warranty against
breakage.
24:7 Contrast
in NXT: If you are planning to wear your 7EYE glasses night and
day or indoors and out, the 24:7 Contrast in NXT is the ticket. It
fades to a yellow tint for better visibility at night and in low light
and darkens to a deep brown that improves contrast by cutting haze.
The inner lens is treated with an anti-fog coating for all weather
performance.

Polarized AF in NXT: The ultimate in non-prescription lens
technology, the Photo Polarized AF in NXT has it all. It's polarized so
it filters out reflected glare and photochromic so it responds to
changing light conditions. Because it is made in NXT, it's
lightweight and virtually shatterproof. The anti-fog coating is so
durable it will last as long as the lenses and the NXT is guaranteed for
life.
