If you’ve ever worn light-reactive (a.k.a. photochromic) lenses, you’re undoubtedly familiar with the following scenario. You’re indoors and your lenses are nice and clear. You step outside to run an errand or go for a drive and your lenses darken up. Then you get inside your car and that comfortable tint starts fading away before your eyes.
Until now, this meant scrambling for your prescription sunglasses. Thankfully, the scramble for your suns is a thing of the past.
SunSync Drive XT is an extra-active light-reactive lens that gets darker outdoors and stays dark in the car. So, you enjoy comfortable, glare-free vision whether you’re in the park or on the highway.
Why do they stay dark in the car?
Why do extra-active, light-reactive lenses like SunSync Drive XT work in the car when traditional lenses don’t? Traditional light-reactive lenses activate and deactivate based on exposure to UV light. For good reason, most car windshields and windows come with UV protection built into them. No UV light getting into the car means no UV to activate your lenses.
SunSync Drive XT on the other hand activates based on exposure to UV and visible light. So, when you get into your car and the windows block the UV, the visible light coming through still activates your lenses.
The “extra” in extra-active.
In addition to working in the car, SunSync Drive XT also get darker outdoors. And not only do they get darker than standard photochromic lenses, they also offer you the darkest outdoor color of any extra-active lens available. They also change from dark to clear faster, and get clearer indoors than any other extra-active light-reactive lens.
Add all this to the standard benefits you enjoy with all SunSync Light-Reactive Lenses, and you get the ultimate lens package of comfort, clarity, convenience, and confidence:
- 100% UV protection
- Targeted blue light filtration
- Exceptional scratch resistance
- Outstanding cleanability
