Wetzlich uses transition technology for photochromic lenses. In their basic state, glasses with only 5% tint cannot be distinguished from clear glasses. When exposed to sunlight, the lenses tint to the equivalent of sunglasses (approx. 80% tint) within 30 seconds.
- 100% UV protection, complete filtering of UVA and UVB radiation
- Significant increase in contrast
- Totally clear indoors
- Darkening in sunlight up to 85% (like sunglasses)
- Fast darkening and brightening
- Available for all lens materials
Transitions® Signature™ Vll lenses provide a balance between darkening, clarity and speed in returning to their initial state. The lenses are suitable for your normal glasses with vision correction and for indoor and outdoor use. The colour of the lenses indoors is clear. The lenses darken quickly outdoors depending on light conditions and absorb 100% of UVA and UVB rays. The lenses remain clear inside a car. The lenses also reduce blue light irradiation.
Transitions® DriveWear™ are lenses that adapt to different light conditions to make driving easier. The lenses are suitable for sunglasses. Transitions® DriveWear™ Glasses should be used outdoors and in the car during the day. The colour varies depending on the light conditions (green/yellow to copper and through to dark red-brown). Unlike other photochromic lenses, they darken completely in a car and offer 100% UVA and UVB protection. The lenses also reduce blue light irradiation.
