Many people know the harm of sunlight to the skin, but not everyone knows that their eyes are also very sensitive to ultraviolet rays. UVB rays are the most harmful to human eyes. Excessive exposure can cause many problems, such as:

Photokeratitis

cataract

Pterygium

Macular degeneration

Pingkula

Conjunctival squamous cell carcinoma

For lifeguards working near outdoor swimming pools, water parks, or lakes or oceans, choosing the right pair of lifeguard sunglasses is essential. For people with poor eyesight, sports prescription glasses can help correct vision while providing comfort during activities.

What characteristics should be paid attention to when choosing lifeguard sunglasses polarized

When buying lifeguard sunglasses, you need to look for certain features to ensure the best sun protection and performance under strong light conditions. On the one hand, you need to look for glasses that block 100% UV rays. In addition, look for large lenses or close-fitting frames around the head.

When working at the water's edge, polarized lifeguard sunglasses are a must. When light hits the surface of the water, it will scatter and cause glare. This glare can make lifeguards very uncomfortable and make it difficult for them to maintain full visibility of the water, which can make it difficult for them to see any potential hazards in the water or notice when someone is in trouble. Polarized lenses help reduce glare by blocking all horizontal light waves.

You also need to choose glasses that are designed to keep your face safe even in the event of sweating and excessive moisture in the air. Anti-fog lenses are useful in hot and humid environments. If you often need to go into the water, a strap or prescription sports goggles will help you transition from water to land smoothly.
