 | With three different light reduction levels, Umbra-coated lenses cover an extremely wide range of applications:
Umbra 25
 Light protection filter with 25% light reduction
For all-round use indoors and outdoors if no sun protection is required
The cosmetic brown tint harmonises with the complexion and is found by many wearers to be more comfortable to wear in artificial light than clear lenses
Umbra 75
Sun protection lens with 75% light reduction
Ideal for sunny weather in moderate climates
Umbra 85
Sunglass lens with 85% light reduction
For sunny weather when increased protection against glare is needed, e.g. at the seaside or in the mountains
