A polarized tinted lens for sunglasses includes a first polarizing tinting member and a second tinting member. The first polarizing tinting member is capable of reducing the transmission of glare through the lens. The second tinting member at least partially overlays the first tinting member so that light passing through the lens in the portion where the first and second tinting members are overlain must pass through both the first and second tinting members. Preferably the sunglasses created thereby are polarized sunglasses with two tints in one lens. The user can adjust the tint though which he sees by tilting his head or adjusting the angle of his eyes.

Embodiments are described that simultaneously block glare arising from the reflection of polarized sunlight and can also allow a polarized liquid crystal display (LCD) to be clearly viewed. Embodiments may be useful for use as polarized sunglasses. Embodiments operate by using a unique property of a circular polarizer. One side of the circular polarizer substantially blocks the transmission of incident polarized light whereas the other side allows substantially complete transmission of incident polarized light. Using these opposite behaviors, polarizing sunglasses can be constructed in which the top portion uses a first side of the circular polarizer to block the polarized glare and the lower portion uses a second side of the circular polarizer, opposite from the first side, to view the LCD. Because two different polarizers are used, these sunglasses are called dual-polarization sunglasses to differentiate them from the traditional linear polarizer sunglasses
