While your standard tinted sunglasses are great for reducing brightness, they don’t eliminate any harsh glare like polarized sunglasses do. Don’t let darker lenses fool you into thinking they offer more protection from UV rays, either. The darkness of the lens does not accurately represent the lenses’ ability to block UV rays. Its a trick.
Always check your label on your sun glass lenses to see what level, if any, of UV protection they offer. Also, remember that dark sunglasses without UV protection will cause much more damage to your eyes than not wearing sunglasses at all. Darker tints on sunglasses with no or little UV protection can cause the pupil to dilate, letting more UV rays into the inner part of the eye. Terrible.
