Some eyewear brands block 100% of UV rays, but only to 380nm, which means they’re letting the most harmful, high energy visible light through the lens. These rays (along with UV) are a leading cause of cataracts, skin cancer and wrinkles around the eyes—great reasons to block them out. All RYDERS lenses—of every tint and shade—block 100% of UVA, UVB, UVC rays plus these harmful, high-energy visible light waves all the way to 400nm.
WHAT IS UV?
UV, or Ultra Violet, is high-energy light that’s beyond the spectrum that’s visible for humans. Other invisible light includes x-rays and gamma rays on the higher-energy end of the spectrum. Infrared rays, microwave rays and radio waves are found on the lower-energy end of the spectrum.
UV radiation is harmful to the eyes and skin. Immediate damage is noticeable in the form of sunburn, but cumulative damage over years or decades may be much more sinister as it can come in the form of cataracts and skin cancer. So think of our lenses like lead vests for your eyes. You wouldn’t opt out of the lead vest during an x-ray, would you?
DOES THE LENS COLOUR OF A RYDERS LENS AFFECT ITS UV PROTECTION?
No, every one of our lenses meets or exceeds the same standards of UV protection. Whether the lens is clear, coloured or dark grey, you have the same protection against UV rays and harmful blue light.
WHAT IS VISIBLE LIGHT TRANSMISSION [VLT]?
When we talk about VLT as it relates to a lens colour, we are talking about the amount of visible light (not invisible UV light) that is able to pass through the lens and reach your eye. The percentage of visible light that makes it through the lens is a very different thing than UV protection. VLT is a carefully measured number to quantify how light or dark a lens is. Some colours however, increase contrast and therefore give the illusion of being brighter than they really are. For example, a grey lens with 50% VLT will seem darker than an orange lens with 50% VLT even though they are transmitting the exact same percentage of visible light.
HOW DOES A VISIBLE LIGHT TRANSMISSION [VLT] VALUE AFFECT UV PROTECTION?
In our lenses, we’re proud to say it doesn’t. All of our lenses—of all tints and shades—block 100% of UVA, UVB, and UVC rays and harmful, high-energy light to 400nm.
