Why You Should Wear Sunglasses Even on Cloudy Days

Most people understand the importance of wearing sunglasses outdoors during hot summer days. Good quality sunglasses help protect the eyes from harmful ultraviolet (UV) rays and help prevent glare. Most people need to realize that sunglasses are vital even on overcast days. 

The harmful rays are present regardless of the season and can cause significant eye damage. Studies suggest that UV light exposure can be just as damaging on cloudy days. Find out why you should wear sunglasses even on cloudy days. 

Understanding UV Rays 

UV energy is invisible to the eye; the only natural and most common source is the sun. The radiation produces vitamin D, which is vital for good health, but it can harm the eyes and skin. UV radiation is divided into UVA, UVB, and UVC, with the first two causing the most harm. 

UVC is absorbed into the ozone layer and does not pose much risk. UVA rays can penetrate deep into the skin and are consistent all year round. Overexposure to the sun’s rays can cause vision problems and increase the risk of blindness. 

Sun Rays on Cloudy Days 

Clouds help block the sun, providing much-needed shade on hot days, but that does not mean the rays are gone. It is vital to realize that UV rays can penetrate through clouds. Some studies also show that particular clouds increase UV radiation. 

Partly cloudy skies increase UVB levels by 25 percent, which can cause sunburnt eyes. Wearing sunglasses daily can help prevent or reduce short-term or long-term eye damage. 

Reasons to Wear Sunglasses 

There are reasons why you should wear sunglasses even on cloudy days:

• They can help prevent eye issues such as corneal sunburn, macular degeneration, and certain eye cancers. 

• Prolonged sun exposure can increase the risk of cataracts. Sunglasses protect the eyes, reducing your chances of developing age-related cataracts. 

• They can help improve vision by enhancing contrast and making it easier to see objects. 

• Sunglasses can prevent the development of benign and malignant eye growths caused by sunlight exposure. 

• They shield the eyes from debris in the environment, especially when it is windy. They keep away dirt, allergens, and other irritants. 

• Sunglasses help reduce glare from surrounding surfaces, improving clarity on overcast days. They help improve driving conditions. 

Tips for Buying Quality Sunglasses

Wearing protective sunglasses is the best way to protect your eyes from the harmful effects of the sun. It is essential to know that the quality of the sunglasses you wear will determine how well you protect your eyes. 

There are issues to consider when shopping for sunglasses. They include size or style, label, lens type, color, and prescription. In most cases, the best quality sunglasses tend to be costlier than regular sunglasses. However, you can get affordable sunglasses of good quality. 

Regular Comprehensive Eye Exams

Apart from wearing eye protection, it is vital to schedule regular eye exams. Early detection of eye conditions is crucial for effective treatment. The exams are preventive as they help provide information. Your eye doctor can offer tips about the best sunglasses to protect your eyes.
