The following FAQ refers specifically to SunSync Drive XT. View the SunSync FAQ and SunSync Plus FAQ for additional details on each product.
What is SunSync Drive XT? |
SunSync Drive XT is an extra-active, light-reactive lens that gets darker outdoors and stays dark in the car. In lab testing, SunSync Drive XT outperformed the leading extra-active photochromic in three key categories:
|
What is the difference between SunSync and SunSync Drive XT? |
SunSync Drive XT retains all the benefits of SunSync Light-Reactive Lenses while introducing in-car activation and a darker outdoor color.
|
What are the benefits of SunSync Drive XT? |
SunSync Drive XT provides wearers the following benefits:
|
|
|
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. |
Will SunSync Drive XT activate indoors in response to interior lighting? |
SunSync Drive XT will not activate in response to interior lighting. If sitting indoors directly beside a window without UV protection, SunSync Drive XT may activate to varying degrees.
|
What materials are available with SunSync Drive XT? |
SunSync Drive XT is available in 1.50 plastic, polycarbonate, Trivex, and 1.67 high-index.
|
What lens designs are available with SunSync Drive XT? |
SunSync Drive XT is available on the following Unity® and Ethos® lens designs:
SunSync Drive XT is also available on Shamir lens designs. |
What colors are available with SunSync Drive XT? |
SunSync Drive XT is available in gray and brown.
|
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 less dark than its fully activated outdoor color.
|
How fast do SunSync Drive XT lenses activate and deactivate? |
Due to the high number of environmental factors that impact performance of light-reactive lenses, it is difficult to accurately provide general activation and deactivation times. However, in lab testing, SunSync Drive XT delivered the fastest fade-back speed in the extra-active photochromic category.*
|
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 blue-light-reducing AR coatings because they intentionally reduce the amount of blue (visible) light reaching the lens, which can negatively impact lens performance.
|
How much blue light does SunSync Drive XT filter? |
As a standard practice we do not promote a single fixed percentage of blue light reduction for any of our products. This is because we do not feel this is the most scientifically appropriate or accurate way to describe what the lenses are actually doing in terms of blue light reduction.
Instead, we refer to spectral transmittance graphs for our products, which demonstrate the percentage of reduction at all wavelengths, not just certain points. |
How does SunSync Drive XT compare to Transitions® XTRActive Lenses?
|
In lab testing, SunSync Drive XT outperformed Transitions XTRActive for darkness, clarity, and fade-back speed.* We encourage you to compare the performance characteristics of SunSync Drive XT with any photochromic brand and are confident SunSync Drive XT will deliver comparable or superior performance to any other photochromic product lines.
