4. The front surface of the eye absorbs 99 percent of the UV radiation. On the surface of the eye, this UV damage predisposes to cancerous growths, as well as noncancerous growths like pterygium and pinguecula. Damage to the cornea can occur when UV light is reflected off the water, like when you’re engaging in water sports or skiing. 5.
Glass is Naturally UVB Resistant. Over time, acrylic will yellow. With a film or coating, acrylic can be UVB protectant, at a cost. Glass is naturally UVB protectant making it a great product to protect furniture as a glass tabletop, art work in frames, or when used as architectural decorative glass, perfect for protecting entire spaces.
Most greenhouse plastics are designed to block UV rays to some degree to protect the plastic and the plants within the greenhouse. Some modern plastics are designed to let UV rays in to better mimic natural growing conditions. Acrylic, polycarbonate, and polyethylene are all used for greenhouses and block different amounts of UV rays.
Both plastic and glass lenses absorb some UV light, but UV absorption can be improved by adding chemicals to the lens material during manufacturing or by applying special lens coatings. Look for sunglasses that block 99 percent or 100 percent of all UV light. Some manufacturer's labels say "UV absorption up to 400nm."
I wouldn't print outside--UV light will be pretty unavoidable. Even average windows block a decent chunk of UV light, allowing you to take the covers off for removing prints and refilling resin. But outside you'll be fighting with rapid curing no matter how well you try and shield the sun.
Paint is by far the best because it contains the elements that best block both UV light and water. The pigment blocks the UV light and the film thickness blocks water penetration. Paint can last for many years if the surface has been prepared well and the areas where water can penetrate (mostly cracks or gaps where siding butts onto trim) have
The spectrum of electromagnetic radiation ranges from radio waves, with a longer wavelength, through normal day light, with its short wavelength UV radiation, to extremely short wavelength X and gamma rays. The shorter the wavelength of radiation, the higher the susceptibility of a plastic to damage.
