Control light at the molecular level.
The science of electrochromics. Transition from crystal clear to perfectly tinted in seconds with a micro-electric charge.
Active Control
Passive transition lenses rely on unpredictable UV rays. Electrochromics use a targeted electric pulse. You dictate the tint, not the weather.
Instant Speed
Chemical reactions happen instantly. Watch your lenses adapt seamlessly to changing environments in ~5 seconds.
Micro-Power
Power is only drawn during the transition state. Once tinted or clear, the lens locks its state, allowing the battery to last 7+ days.
A marvel of material science.
WaSun lenses are constructed using a multi-layer stack of advanced nano-materials. When you tap the frame, a microscopic voltage pushes ions from the storage layer into the electrochromic layer, absorbing light and darkening the lens instantly.
What this means for you.
Photochromic Problems
Legacy transition lenses rely entirely on UV rays. When you step indoors, the chemical reaction slowly reverses, leaving you with dark lenses for 5-10 minutes.
Worse, car windshields block UV light, meaning your expensive photochromic lenses will not tint while you're driving.
Electrochromic Freedom
Because electrochromic lenses use an electrical charge, they are independent of UV light. You control the tint.
Step inside? Tap the frame and the lenses clear instantly. Driving into the sun? Slide the arm to engage a 100% dark tint. Complete control, everywhere.
