Visible Light Transmission
0-10% – very heavy tint, too dark for most needs. 10-30% – heavy tint for bright sunny days. 20-60% – light tint, great for cloudy, overcast conditions and shady trails. 60-80% – very light tint (often coloured), for improving contrast in low-light conditions, think dawn or dusk. 80-100% – little to no tint, this what you want in the dark.
