• Product description+

  The deepest filter in the range, made for the hours before bed. The red lens blocks almost all blue light — and most green too — so your whole view turns a deep red.

  • Blocks around 99% of blue light, casting everything in deep red.
  • Blocks effectively all UV, so nothing harsh gets through, even under artificial lighting.
  • The deepest, most tinted lens in the set — the more intense of the two night lenses, for the last hours of the evening.

  Available in clear, grey or brown frames, with a storage bag and cleaning cloth. This selected product has no eye prescription correction.
