Summer Sun Tips: How to Buy the Right Sunglasses
The National Eye Institute recommends wearing sunglasses that block UV rays whenever you go outside during the day—no matter your age or the time of year. But how do make sure your sunglasses offer the best protection?
Choose sunglasses that block both UVA and UVB rays, both of which are types of energy radiated from the sun that can harm our eyes. According to Dr. Andrea Thau, president of the American Optometric Association, sunglasses with a label or tag indicating they provide “100% protection” against UVA and UVB or UV 400 are a must.
Darker sunglasses that block visible light are also essential in the bright summer sun. Studies show damage from sunlight can have a negative effect on night and color vision. Sunglass lenses should be large enough to cover as much of the sensitive skin around your eyes as possible, to reduce the risk for skin cancer. And don’t forget children’s eyes—sun damage accumulates over time.
