Performance in Overdrive
SunSync Drive XT takes the old notion about light-reactive lenses not working in the car and throws it out the window. Combining in-car color retention with ultra-dark outdoor color and exceptional indoor clarity, this conventional extra reactive lens takes the show on the road and anywhere else life takes you.
Darker. Clearer. Faster.
SunSync Drive XT outperforms other conventional photochromic lenses in three key areas:
- Outdoor darkness
- Indoor clarity
- Fade-back speed


Why Does SunSync Drive XT Work in the Car?
Whereas traditional light-reactive lenses activate based on exposure to UV light only, SunSync Drive XT responds to both UV and visible light. So the lenses retain color in the car, even if the windshield blocks the UV.

What is the difference between SunSync Drive XT and Original SunSync?
SunSync Drive XT retains all the benefits of SunSync Light-Reactive Lenses while introducing in-car activation and a darker outdoor color.
-
How does SunSync Drive XT work?
SunSync Drive XT activates in response to both UV and visible light unlike standard photochromic lenses which activate in response to UV light only.
-
Why does SunSync Drive XT work in the car?
Standard photochromic lenses that only activate in response to UV light do not typically darken or stay dark in a car because most car windshields block UV light from entering the car.
SunSync Drive XT lenses activate in response to both UV and natural visible light. Therefore, the visible light coming through the windshield and side windows allows the lenses to retain color in the car. -
What does SunSync Drive XT look like?
SunSync Drive XT is near-clear indoors and darker than original SunSync outdoors. In its activated state in the car, SunSync Drive XT is slightly less dark than its full dark color outdoors.

What colors are available with SunSync Drive XT?

-
Is SunSync Drive XT compatible with other lens enhancements?
Yes. In fact, adding a premium anti-reflective coating like TechShield® Elite will enhance the performance of SunSync Drive XT. However, we do not recommend adding a blue-light-reducing AR coating like TechShield Blue because it intentionally reduces the amount of blue (visible) light reaching the lens, which can negatively impact lens performance.

"Sunsync lenses made it very convenient to have 2 in 1 pair of lens when driving or coming out of a building specially here in Florida. The automatic change from indoors to outdoors and vice versa is fantastic. I definitely will recommend this product to my family and friends who use glasses."
