• How does SunSync work?

  Photochromic nanoparticles “unfold” when exposed to UV, absorbing light, blocking UV, and appearing colorful (dark). When the UV source is removed, the nanoparticles gradually return to their original state and appear colorless (clear).

• How fast does SunSync activate and deactivate?

  Due to the high number of environmental factors that impact the performance of light-reactive lenses, it is difficult to accurately provide general activation and deactivation times. The best way to gauge and demonstrate performance speed is to request a SunSync demo lens.​

• Is SunSync compatible with ​other lens enhancements?

  Yes. In fact, adding a premium anti-reflective coating like TechShield^® Elite will enhance the performance of SunSync.

• How much blue light does SunSync 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 publish spectral transmittance graphs that show the percentage of reduction at all wavelengths, not just certain points. View SunSync spectral transmittance graphs here.

• How does SunSync compare to Transitions^® lenses?

  SunSync is an excellent base lens that utilizes the latest advancements in photochromic technology. We encourage our customers to compare the performance characteristics of SunSync with any base photochromic offering.​
