UV are ultraviolet light rays from the sun that are damaging to the skin and eyes over time. There are different types of UV rays, including UVB rays which make up 5% of the sun’s rays. The best UV protection is a rating of UV 400, which blocks 99% to 100% of UVB rays. Then, there are UVA rays that make up 95% of the sun’s rays. These are more damaging and penetrate deep into the skin. UV protected lenses block wavelengths up to 400 nanometers and block 75% to 90% of visible light from the sun. UV protection is important because it reduces the risks of macular degeneration – which affects central vision, cataracts – cloudiness in the clear lens of the eye, and photokeratitis – exposure to ultraviolet rays that damage the cornea. Sunlight exposure throughout your lifetime is inevitable, so it’s important to know how polarized and UV differ in protecting your vision.

At this stage of life, it is important to establish good eye health habits for a lifetime of strong, healthy vision. For example, people with diabetes or pre-diabetes need to have regular eye exams to make sure they don’t develop diabetic eye disease. A big part of diabetic eye care is working with your doctors to control weight and blood sugar, as well as blood pressure and cholesterol.
