Transitions glasses have some great benefits, especially when chosen as everyday glasses. Photochromic eyeglass lenses darken when exposed to ultraviolet rays in daylight, but they have a major disadvantage in that they have not been appropriate or beneficial for use as driving glasses until now.

When you wear glasses to drive, you’re generally trying to address two main concerns (aside from prescription vision remedial glasses, of course): glare from oncoming traffic or reflections from road surfaces caused by moisture, for example, and prescription sunglasses that can dim or reduce the glare of incoming sunlight. However, modern windshields eliminate one of these benefits, as they are designed to absorb the ultraviolet light that has been necessary to activate the photochromic reaction in eyeglass lenses.

Drivewear lenses resolve this conflict by using exclusive, patented transition lens tints that respond to both visible and ultraviolet light. This allows the driving glasses to change color tint as light intensity changes, thereby improving the driver’s vision. They also block 100% of incoming UVA and UVB sunlight.

In almost all driving situations where there is a lot of sunlight, these lenses provide optimized comfort and safety for the driver. In less intense daylight, these glasses have a slight yellowish tint that is known to provide high contrast and thus allow the driver to easily distinguish objects in their field of vision. When activated behind a car windshield, the yellowish tint changes slightly to a more coppery tint that also reduces glare and actively filters some of the visual sunlight while maintaining excellent visual characteristics.

Another benefit of this color tint is that it is optimized to allow a strong carryover of colors in the red and green spectrum and therefore makes it easier to first see traffic lights from a distance and then easily differentiate between colors.

When worn as everyday eyewear outside the car, photochromic transition lenses continue to darken and filter visible light in proportion to the intensity of daylight the lens receives, providing active comfort in changing conditions sunlight and filters excess daylight.

However, like all tinted glasses, they should not be used for night driving, as there is broad agreement among experts and institutions that no attempt should be made to filter incoming light at night, as it is intended to reduce the integrity driver’s vision and thus adversely affect safety.
