The Sun & Your Eyes
The easiest, and possibly most effective way to take care of your eyes is by protecting them from the ultra violet rays from the sun.
Ultra violet rays (UVA/UVB) can damage your eyes over time and can cause cataracts. In order to protect your eyes from these rays, simply wear sunglasses that block UVA/UVB rays when the sun is bright!
Hats with a wide brim are another way to help protect your eyes. Some light reaches your eyes around the sunglasses, and the hat blocks most of those.
Contacts can also have UV protection. But be careful, not all sunglasses provide UVA/UVB protection, so be sure to check the label to make sure the sunglasses you are buying will protect your eyes.
