Teaching your children to wear sunglasses may be more important than giving them a college fund.
All children should be taught to wear sunglasses, especially between 10 AM and 2 PM, when ultraviolet exposure is the most dangerous. This is true even for children with darker eye colors, even though their darker pigments afford partial protection. Of course, children with light-colored eyes need sunglasses all the more. Ultraviolet exposure is at its peak when children are at high altitudes, snow-covered landscapes, bright sandy beaches, or near reflective bodies of water.
Most people wear sunglasses to reduce glare. This is trivial compared to the long-term protection they afford for the precious ability to see. Parents can set a good example for their children by wearing sunglasses at the appropriate times.
All sunglasses are not the same. Effective sunglasses should block both UVA and UVB radiation. Large lenses that fit close to the eyes are best. Those that block visible blue light are even safer. Thankfully, all sunglasses block UVB radiation. A great many sunglasses, however, do not afford UVA protection. Expensive brand names and polarizing lenses are no guarantee. The sunglasses must be measured to block 99% to 100% of UVA or UV400 (400 nm is the wavelength of UVA radiation).
