UV Rays and Your Eyes
Hollywood can create or change a movie star’simage with a particular pair of sunglasses. Models, musicians, and movie stars popularize trendy shades and out-of-sight styles. But are your sunglasses fashionable and functional? With the right ingredients, sunglasses can protect your eyes against ultraviolet (UV) radiatio, bright visible light and glare. The colour, darkness and fashion of sunglasses has little to do with UV protection. Many countries set standards for UV absorption of sunglasses. Special lens treatments can add polarizing filters, mirrored coatings, or special tints to sunglasses that can reduce glare, reflect bright light, enhance contrast, or make it easier to see on overcast days.
When purchasing sunglasses, people are looking for more than just a great look. They want to cut down the exposure to bright light, harmful ultraviolet (UV) radiation and glare. |
