Rex Specs lenses are all engineered from premium materials to provide protection from anything your dog may encounter. All of our lenses are impact resistant and UV 400 rated, blocking 99% of harmful UVA and UVB rays.

Clear:
Allows 92% of visible light to pass. For everything except protection from brightness (still UV 400). Perfect training lens.

Red Mirror:
Allows 23% of light to pass. Giddy up! The red mirror is great for most dogs and is very similar to the smoke lens with a bit more style.
