A spare set of brown Photochromic lenses for the SWAMPER.
LIGHTEN + DARKEN AUTOMATICALLY
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.
LIGHT CONDITIONS: designed for low to very bright light
PHOTOCHROMIC EFFECT: automatically adjusts from light to dark and vice versa to suit light conditions
COLOUR EFFECT: darkens colours and slightly increases contrast by reducing blue hues
VISIBLE LIGHT TRANSMISSION: 47%—15%, category 1—3
UV PROTECTION: 100% UVA, UVB, UVC and harmful blue light to 400nm
POLYCARBONATE LENS MATERIAL
Polycarbonate is the extraordinarily durable thermoplastic that’s used in bulletproof glass, riot shields and astronaut helmets. It’s the ideal material for performance eyewear because of its high impact resistance, inherent UV protection and light weight. All of our lenses are made of polycarbonate.
All of our lenses block 100% of UVA, UVB, and UVC rays, and harmful blue light to 400nm. These harmful rays are a leading cause of cataracts, skin cancer and wrinkles around the eyes—all great reasons to block them out.
All of our lenses are shatterproof, meaning they won’t break up into dangerous little shards when impacted. An extremely strong impact may damage the lens, but it will never shatter. If astronauts trust this material to keep their heads from exploding while on a 17,000 mph space walk, you’ll have nothing to worry about on your adventures, no matter how fast you’re going.
The lenses in all of our sunglasses are made by injecting molten polycarbonate into a mold that is specially shaped to eliminate distortion. This process makes the lenses optically correct, increasing comfort and minimizing eye fatigue.
We apply a scratch-resistant coating to all of our lenses. Though this process makes the surface of the lens considerably harder than the base lens material, it’s impossible to make the lenses completely scratch proof (short of making them from diamonds) so please care for them properly as they may still scratch under certain conditions.
