UV Protection Sunglasses
European experts state in the journal that "under average conditions, more than 50% of eye exposure is caused by scattering and cloud reflection." Clouds and haze increase scattering. Experts claim that reflected UV light is an important and underestimated contributor to vision damage.
Also, while we have long been warned to protect our skin when out in the midday sun, at different times of the year and at different latitudes, peak eye exposure to UV depends on the angle of the sun, and it can occur in the early morning or late afternoon.
Children are particularly vulnerable to UV damage to their eyes. The lens inside their eyes is still clear and their pupils are wider than those of adults, which allows more damaging light to reach the retina, where the visual image must be focused if we are to see clearly. Once the retina is damaged, the visual impairment is likely to be permanent.
Here are some things to consider when choosing lenses that will protect your eyes from the dangers of excessive UV exposure
All sunglasses today, even those purchased at dollar stores, should come with full (400 mm) UV protection, although more expensive lenses provide better visual clarity. The color of the lenses doesn't matter, though lighter tones don't work well for people whose eyes are very sensitive to bright light. If the label says UV 400, chances are that it is true or very close.
