Light conditions are constantly changing. Time of day, weather, or simply a change in location or direction of travel will alter the intensity of the sunlight that’s reaching your eyes. Photochromic lenses automatically adjust to suit the amount of sunlight at any given time.

Our Photochromic lenses are made using an injection process that ensures they’re optically correct, decreasing eye fatigue and increasing comfort. At all tint levels — from the lightest to the darkest — RYDERS Photochromic lenses provide protection against 100% UVA, UVB, UVC and harmful blue light to 400nm.

When exposed to sunlight, the lenses will start to darken instantly. The time they take to reach maximum darkness depends on a number of factors including the intensity of sunlight and air temperature. Generally speaking, the adjustment from light to dark is quite rapid. The adjustment from dark to light will begin instantly but occur more gradually.

It’s important to note that most car windshields block the UV light that’s needed for the Photochromic reaction to take place. For this reason, you should not expect the tint of the lenses to darken while driving in bright conditions.
