Thin & Dark glass lenses, also known as transition or photochromic lenses, are innovative eyewear lenses designed to adapt to changing light conditions. These lenses are engineered with special photochromic molecules that react to ultraviolet (UV) light, causing the lenses to darken when exposed to sunlight and lighten indoors or in low-light settings.
Corning is synonymous with innovation in the world of optical technology, particularly in developing high-quality glass lenses. Among their most notable offerings are the Photogray Extra (PGX) and Thin & Dark lenses. Both crafted from premium glass, these lenses cater to diverse needs but with distinct characteristics. This article will delve into these differences to assist you in choosing the most suitable lens for your eyewear.
Corning’s Thin & Dark lenses are engineered to balance aesthetics and functionality. They are thinner and lighter than standard glass lenses, and notably, they achieve a slightly darker tint than the PGX lenses under similar conditions.
