Polarized lenses have a filter laminated on them that only allows vertically oriented light to pass through, while non-polarized lenses are usually just tinted to block light. Non-polarized lenses do not contain a filter to remove glare.Know More
Sunlight can be reflected in many directions off of horizontal surfaces, such as water, land, wet roads and the hood of a car. These horizontal reflections create a glare that can blind a driver, causing an accident. According to Perfect Glasses USA, polarized lenses are good for people who drive for a living and need to see well at any time of the day. People who like to fish or boat appreciate polarized lenses, as the lenses remove the glare and help the fisherman see fish or spot rocks that might damage the boat. Polarized lenses are mainly gray and yellow.

According to Eyeglass Guide, Transitions lenses work because they contain certain photochromic dyes that react when they are exposed to the ultraviolet rays in sunlight, causing the eyeglass lenses to activate, or become darker. When the UV light diminishes, the photochromic dyes again react and cause the tint in the lenses to become lighter. As light levels change during the day, the tint in the lenses continues to adjust.Full Answer >
