TINTS: Tinting can range from light tinting for indoor wear to dense tinting for outdoor use. For outdoor use, UV protection should be added to all tinted lenses.

PHOTOGRAY / PHOTOBROWN: Photogray is a glass lens which darkens in the sunlight. It is activated by UV radiation. These lenses do not darken fully when driving, because the windshield absorbs much of the UV radiation. It is available in gray and brown.

POLARIZED: This lens is very popular among fishermen as it cancels glare coming from the water's surface.

TRANSITIONS: This lens is similar to photogray, but is constructed of plastic. This lens is much lighter than the glass photogray lens. Advancements in this lens have made it one of the most popular options due to its speed in lightening / darkening and its virtually clear appearance indoors.
