Harmful UV (ultraviolet) ray exposure from the sun can cause eye injuries such as photokeratitis, which is when the UV rays burn the surface of your eyes. This condition can be very painful and make your eyes red or your vision blurry. The best way to protect your eyes from the sun’s harmful UV rays is to wear sunglasses with 100% UV ray protection (both UVA and UVB). Polarized sunglasses can help reduce the intensity of the reflection off of surfaces such as water or cars. Also remember to wear a wide brimmed hat to cover gaps from the sunglasses where you may still be exposed to UV rays.
Swimming pools contain many chemicals such as chlorine that can irritate your eyes and cause blurry vision or make your eyes red. Wearing goggles whenever you are swimming can help protect your eyes from these chemicals or potential pathogens in the water. If you are a contact lens wearer, always remember to remove your contact lenses prior to swimming or hot tub use. Contact lenses can trap bacteria or other pathogens and potentially cause serious eye infections.
The summer hear and dryness can cause dry eyes. Wearing sunglasses or wrap around eye protection can help protect your eyes from the heat. Regular use of artificial tears (preferably preservative free) and maintaining hydration can be helpful with dry eye symptoms.
