Wearing sunglasses is vital to ensure your best optical health. Although many people believe that they are only necessary in the summer, they are actually useful all year round. Sunglasses act not only as a stylish accessory, but also protect your eyes from harsh environmental effects. Here are several reasons you should invest in a pair of protective sunglasses:
The harmful UV rays of the sun can actually cause sunburn to your eyes. This is called photokeratitis. Although this is a temporary condition it can be quite painful. You will experience a feeling of having grit in your eyes as well as heavy tearing. Your eyes will also be more sensitive to light and feel like you have something in your eye. Photokeratitis rarely results in permanent damage. Wearing sunglasses will protect your eyes from photokeratitis.
Prolonged exposure to UV rays can cause cataracts. Cataracts are a clouding of the eye that can impair vision. That is why it important to wear protective sunglasses all year long starting from early childhood. Many parents will slather on the sunscreen but not think to provide their little ones with sunglasses. UV protected lenses are a must for children especially when near water or when it is very snowy.A cap with a visor will also assist in protecting your eyes.
UV rays can also cause macular degeneration which is damage to the retina. Your retina is the light sensitive part of your eye. When macular degeneration occurs it can interfere with vision and in severe cases it can lead to complete or partial vision loss. Simply wearing sunglasses will help lessen the chances of developing macular degeneration later in life.
Without proper protection from the sun the delicate skin around your eyes are at risk of developing skin cancer. Wearing sunglasses and a wide brimmed hat can keep your eyes well shaded.
To protect your eyes from the harmful rays of the sun look for sunglasses that offer 99 to 100 percent UV protection. Glasses that offer wrap around protection and that sit close to your face will provide the best protection. Larger lenses will also help block out the rays more effectively. Although blue blocking lenses aren’t recommended for driving, they are an excellent choice in both summer and winter as they help combat the glare of the sun and snow.
