Sunglasses protect your eyes from harsh environments, but have you ever wondered if they are beneficial for them on cloudy days? Your eyes need complete protection from harmful UV rays even when the sun is hiding in the shade of clouds. From protection against UV exposure to enhancing vision and visibility, sunglasses help us a lot under harsh weather.
Read on to learn about the benefits of wearing sunglasses on a cloudy day and dispel the misconceptions about their usage.
Risk and Dangers of Harmful UV Rays on Cloudy Days
Clouds Do Not Provide Complete Protection
People are often under the misconception that clouds pose as a shield, blocking harmful UV rays. However, even though they may partially act as a filter for UV radiation, they don’t fully protect your eyes, resulting in a significant amount of UV rays reaching the earth’s surface.
UV Rays can Pass Through the Clouds.
Even when the sky is covered with clouds, and there is no sun in sight, the UV rays can go through the cloud cover and reach your eyes and skin. This exposure to UV rays can result in both short-term and long-term complications for eye health.
Environmental exposure can also lead to hay fever, for which you can opt for various effective ways to relieve hay fever.
Higher Risk of Damage to Eyes
Long exposure to the sun’s UV rays can lead to an increase in the risk of damage to the eyes and developing conditions such as photokeratitis and cataracts, which can result in permanent vision loss.
Higher Risk at Higher Altitudes
For Individuals who reside at higher altitudes or spend significant amounts of time in mountainous areas, the intensity of UV increases due to a thinner atmosphere and less filtration of UV radiation.
Reflective Surfaces Enhance Exposure
Even with the clouds, UV rays can reach your eyes through the reflecting surfaces, including water, snow or sand, increasing the intensity of exposure. This means that the people living near water bodies will be more affected by it.
