Importance of UV Protection in Sunglasses

Many people may see sunglasses as just a fashion accessory, but they also help protect the eyes from dust, wind, and harmful UV rays. UV protection is the best reason to wear sunglasses. UV rays, which reflect off buildings, water, sand, and snow, can damage the eyes and the skin around the eyes. Sunglasses offer protection even on cloudy days.

When shopping for new sunglasses, find out their UV protective features. July is UV Safety Month, a special time to find out the importance of UV protection in sunglasses. 

UV Coating on Sunglasses 

The UV coating on sunglasses can help protect the eyes from harmful radiation. Short-term exposure to UV radiation without protective glasses can cause damage to the eyes like a sunburn. The eyes can become gritty, red, and puffy, and if you are sensitive to light, you may experience excessive tearing.

Long-term exposure to UV radiation can increase the risk of developing macular degeneration or cataracts later in life. However, UV damage can also occur in children. Sunglasses offer UV protection that helps keep the eyes healthy for life.

Good Quality Sunglasses

The quality of sunglasses differs significantly, and they do not provide the same protection. The best way to protect your eyes from UV rays is by choosing the best quality sunglasses. Choose sunglasses that block 100 percent of UVA and UVB rays.

Consult your optician at Cobb Corner Eye Care to find out the best sunglasses for your needs. Choose sunglasses in a wraparound style with large lenses for optimum protection. Performance sunglasses are ideal for an outdoor lifestyle. The sunglasses’ darkness or color does not determine their UV protection level.

Sunglasses and Losing UV Protection

Sunglasses can lose their UV protection over time. But if you buy good-quality sunglasses, it can take years before they lose their protective function. Replacing your sunglasses every few years will help ensure that you get the best protection.

When choosing a style, think about temple coverage and fit. How well the sunglasses fit will determine the protection, especially when exposed to direct or heavy sunlight. 

UV Protection vs. Polarization 

It is essential to understand that polarization is different from UV protection. Many manufacturers advertise the two terms as similar, but they are not. Polarization is the ability of the lens to reduce glare and haze in sunlight, so it does not protect the eyes from UV. However, polarized lenses can contain UV blocking features. Ensure that you distinguish the features when buying sunglasses. 

Quality and Cost of Sunglasses

Good-quality sunglasses are usually more expensive. Some brands are famous for their quality, and the sunglasses come with UV protection. The protection is in the lens, and heat exposure or cleaning cannot damage it. If you are looking for budget sunglasses, make sure that you consult your eye doctor to determine the level of protection. An eye care professional can measure the amount of UV that passes through the lenses. 

Children are also at risk of UV damage, especially when they spend hours playing outdoors. Protect your children’s eyes by getting them sunglasses. If you are involved in sports, look for sunglasses specific to your sport.
