Sunglasses may also be labelled UV 400 and block at least 95% of UV between 190 and 400nm. The standard requires that sunglasses claiming a level of UV protection must meet this claim. It is important that the price of sunglasses not be used to gauge the quality of protection from UV radiation.
AFAIK, the roof glass on the Y does NOT have IR/heat protection. Many of the members here tint their roof with 30% or greater UV/IR blocking film. I, on the other hand, have the roof shade from Tesmanian (v2 with magnets). It works wonders against scorching CA sun. I am very comfortable in 100 degree weather running the AC at 70 degrees.
FDA has found that sunlight reflecting off of certain surfaces “further increases exposure to UV radiation.” 14 As a result, FDA has studied glass and plastic surfaces as a means of protecting the eyes from harmful sun exposure and has determined that certain materials made into sunglasses can provide near 100% UV (both UVA and UVB
UV exposure is a powerful attack on the skin, creating damage that can range from premature wrinkles to dangerous skin cancer. Damage from UV exposure is cumulative and increases your skin cancer risk over time. While your body can repair some of the DNA damage in skin cells, it can’t repair all of it.
Glare protection refers to the portion of sunlight we’re able to see. So all dark lenses come with glare protection as it blocks or reduces part of the visible light. But there’s also an invisible part, which is known as UV light. And our eyes need to be protected against this – even on cloudy days when the sun is only partially visible.
