Convex Vision Photochromic Lenses — One Lens, All Lighting Conditions
The Business Case: Fewer Pairs, Higher Satisfaction
Photochromic lenses solve a problem most patients don't think to ask about until it's pointed out: needing two pairs of glasses for different lighting conditions. Positioning this as "one pair that adapts" rather than "an upgrade" tends to land better with price-sensitive patients, since it reframes the cost against buying a second pair of prescription sunglasses.
Core mechanism: lenses sit at a light 5% tint indoors — visually indistinguishable from standard clear lenses — and darken to sunglass-level tint within 30 seconds of UV exposure.
ColorMatic® 3 (Rodenstock Technology)
This is the premium recommendation within the photochromic category.
Key features to lead with:
100% UV protection and glare protection
Fast tint transition in both directions (darkening and clearing)
Integrated blue light reduction — relevant for patients who are also heavy screen users
Available in grey, brown, and green
Available across 1.54, 1.60, and 1.67 index — so this isn't limited to standard-thickness lenses only
Blue Light Reduction — A Secondary Selling Point
Worth mentioning to patients who spend significant time on screens: even in its clear (non-activated) state, the lens filters 34% of light in the 400–455nm blue light range. Once partially activated (around 80% transmission), that filtering increases to 46%. This gives you a talking point for patients who are hesitant about the photochromic tint itself but interested in blue light protection — the benefit exists even before the lens visibly darkens.
