Transitions are adaptive lenses that automatically adjust from clear to dark depending on external sunlight conditons. As well as helping with visual performance, transitions reduce eye fatigue and strain as well as blocking 100% of UVA/UVB light. With UVA/UVB rays being a contributing factor in cataract formation, it is essential to keep your eyes protected.
These photochromic lenses are ideal in that the technology is built in to your lenses so you have ready protection whenever you need without having to constantly switch between your prescription eyewear and sunglasses. Transitions lenses are activated by ultra-violet light which is why they remain clear indoors and darken when exposed to sunlight. The darkening of the lens is variable depending on sunlight conditions. On a bright sunny day, the lens will be at its darkest whereas on a cloudy day, it may darken only slightly. However, whatever the light conditions, you can be assured that you are protecting yourself from those harmful UVA/UVB rays.
Transitions lenses are available in all types of prescriptions from single vision to progressive and high index. There are varying types of progressive lens available to suit your lifestyle needs from an everyday lens to one that is suitable for driving and even polarized Transitions which allow for variable polarization that adjusts to match outdoor glare levels.
