With
photochromic lenses, the intensity of colour changes according to the level of
sunlight; becoming darker in bright conditions and fading to clear in darker
conditions.
Hoya's high quality photochromic lenses can be worn throughout the day, with no
need to switch to and from regular sunglasses. The colours are carefully
selected for increasing contrast and to most effectively eliminate the blinding
effects of the sun.

Hoya's
advanced photochromic spin coating
Suntech
is a photochromic top layer which is applied to the front surfaced of the lens
using Hoya's high performance spin coating technology. Using advanced, fully
computer-controlled equipment, the photochromic material is applied to the lens
surface in an exceptionally accurate process. During the follow up treatment,
special emphasis is placed on the adhesion to Hoya's Eynoa 1.67 and Eyas 1.60
lens materials. this forming a reliable composite with a long life span.
