Don't forget to wear your sunglasses...
Sunglasses should be worn all year round however not all sunglasses are created equal therefore its not enough to just wear any kind. Here's the rundown:
Sunglasses should be worn anytime you are outdoors, particularly under these circumstances:
during the summer, when the level of ultraviolet radiation (UVA and UVB) is at least three times higher than during the winter; when at the beach or in the water; when participating in winter sports, especially at high altitudes; when using medications that can cause photosentivity
You should always buy sunglasses with this feature. Long-term exposure to ultraviolet (UV) radiation in sunlight is linked to eye disease. UVB radiation is considered more dangerous to the eyes and skin than UVA radiation.
Both plastic and glass lenses absorb some UV light, but UV absorption can be improved by adding chemicals to the lens material during manufacturing or by applying special lens coatings.
Look for sunglasses that block 99% or 100% of all UV light. Some manufacturers’ labels say “UV absorption up to 400nm.” This is the same thing as 100% UV absorption. (eyecareamerica.org)
