What VLT means

VLT stands for visible light transmission: the share of daylight that passes through a shield or lens. The lower the number, the darker the lens. For example, the Daytona Viper Mirror Shield is rated at 8% VLT.

Choosing a tint by light level

  • S0, above 61%: very light. Overcast or foggy days, and night riding.
  • S1, 42% to 60%: light. Dull, overcast and foggy days.
  • S2, 12% to 41%: medium. Partly sunny days and most weather.
  • S3 and S4, 0% to 11%: dark. Bright, sunny days.

Choosing a tint by time of day

  • Daytime: mirror, blue, gold, rainbow, green, red or photochromic.
  • Day and night: photochromic or smoke.
  • Night: photochromic or clear.

What REVO coating is

REVO is a multi-layer mirror coating on the outside of a lens. It cuts glare and reflections in bright light, and its mirrored finish hides your eyes from view.
