Transitions XTRActive the first truly Photochromic
Sunglass Resin Lens

Transitions
XTRActive - the first truly photochromic sunglass resin lens - is
now available from Matheson
Optometrists.
It offers
the darkening capabilities of glass photochromics and the lightweight
comfort of plastic lenses.
Blocking 62%
of visible UV light in just 30 seconds, Transitions XTRActive is
superb for those who want an alternative to glass photochromic lenses
but need a darker tint than standard Transitions lenses.
Ideally worn
by those who spend most of their time outdoors, the grey tint lens
is available in single vision, bifocal, trifocal and varifocal.
