Transitions spectacles have some great benefits particularly when choosing them as every day spectacles. The photochromic lenses in the spectacles darken as they become exposed to the ultraviolet rays in daylight-but they have one significant disadvantage in that until now they have not been appropriate or beneficial for use as driving spectacles.
When wearing spectacles for driving, you are typically trying to address two primary concerns (apart from the prescription eyeglass lenses remediating vision of course) – glare from either oncoming traffic, or reflections from road surfaces caused by moisture for example, and as prescription sunglasses that can attenuate or reduce the brightness of incoming sunlight. Modern windscreens however take away one of these benefits as they are designed to absorb the ultraviolet light that has been necessary to activate the photochromic reaction in the glasses lenses.
Drivewear lenses resolve this conflict by using unique and patented dyes in the transitions lenses which do respond to visible light as well as ultraviolet light. This enables the driving spectacles to change color tint as the light intensity changes and consequently improving the driver’s vision. They also block 100% of incoming UVA and UVB sunlight.
