Fog-Free Lenses- These are great for humid environments or unstable climates. They are also good for moving from one extreme to another.

Mirrored Lenses- Mirrored lenses reduce eyestrain outdoors and in sunny environments while protecting the eyes. Mirrored glasses are just as dark as the smoke lenses, they just have a different appearance when on the outside looking in.

Smoke Lenses- Smoke lenses greatly reduce eyestrain in sunny environments but also allow visibility in dark environments. The smoke lenses are similar to a sunglass lens as far as appearance.

Sunglasses- Sunglasses provide protection from harmful light rays; however, they are not impact resistant like a safety glass.
