If someone were to ask your professional opinion on the perfect lens to enhance with a photochromic, you wouldn’t be alone or incorrect in responding, “progressive, bifocal, or single vision.” With all the benefits of light-reactive lenses, they’re a natural fit for everyday eyewear options. But, there’s another lens type that’s so perfectly suited for a light-reactive enhancement, it’s surprising more eye care professionals don’t utilize it as a fantastic second-pair recommendation.

In part one of this three-part series, we took an in-depth look at standard light-reactive lenses . In this second installment, we’ll be covering their extra-active associates.

Eye care professionals were asked for their opinions on SunSync's revolutionary offering and were quick to heap praise on the ultra-fast lens that changes from dark to clear in seconds.

The first photochromic lenses appeared in 1964, and quickly drew interest for their unique ability to darken in sunlight and fade back indoors. However, the first generation of photochromic lenses came with cosmetic and functional barriers – two of the largest being that it took them about an hour to fade and they never got fully clear.

Fast forward more than half a century, and the technology has greatly expanded, as have the types of light-reactive lenses available. Reaction speeds, darkness, clarity, and overall aesthetics have all improved greatly, and there are now four different types of light-reactive lenses available: standard, extra-active, ultra-fast, and polarized.
