How does a photochromic lens work?
The lens darkens when exposed to UV light and clears again as the light fades. It adjusts automatically, so you never need to change lenses.
Do photochromic lenses work behind a car windscreen?
Most windscreens block UV, so photochromic lenses darken less while driving. For driving in bright sun, a fixed Smoke lens like Revolver or Jager is the better choice.
Which lens option should I choose?
Day / Night suits all-day outdoor use. Clear / Grey suits people who spend more time in lower light and want a lighter tint.
Are Tsunami sunglasses ballistic rated?
Yes. They are certified to EN166, ANSI Z87.1 and AS/NZS 1337.1, and exceed US military ballistic requirements.
