What is the best UV rating for sunglasses?

Best UV rating for sunglasses?

You may know that the best way to protect your eyes from the sun’s harmful UV rays is to wear sunglasses when you’re outside, but how much UV protection do you need?

The answer is within the numbered rating range, and the best UV protection rating offered is UV400.

What level of UV do sunglasses need?

The higher the rating, the better, so look for sunglasses labeled UV400 that provide almost 100% protection against harmful UV rays.

The UV 400 protective lens blocks wavelengths up to 400 nanometers. It also filters 75% to 90% of the visible light from the sun. This light penetrates the Earth’s atmosphere and reaches the skin and eyes in the form of UVA and UVB rays.

How good is the UV protection of polarized sunglasses?

Polarized sunglasses help protect your eyes from dazzling glare, but they don’t always provide the best protection against harmful UV rays. That’s why most sunglasses combine polarized lenses with UV protection.

How Polarized Sunglasses Work:

    • Polarized sunglasses lenses use a special filter to block glare, such as strong light, reflected off glossy surfaces such as water and snow.
    • Polarized sunglasses are often recommended for water sports and winter activities to improve visibility and reduce glare discomfort.

For example, many of the cheaper polarized sunglasses do not provide adequate UV protection. Why UV protection is important

The damage to the eyes and skin caused by UV rays from the sun is cumulative. That is, the risk of developing eye conditions and other conditions related to the sun and UV rays continue to increase throughout life.

Children are more outdoors than adults, so they are at increased risk of eye damage from the sun’s rays. Also, the eyes’ lenses are more transparent than adults, making children more susceptible to eye damage. As a result, UV light can penetrate deep into the eye.

However, the damage caused by UV exposure as a child often does not appear until the age of 40, so it is important to wear UV400 sunglasses for life to protect your eyes.

How to know that UV protects your sunglasses?

The amount of protection is also indistinguishable by the color of the lens, as the shade of the lens has nothing to do with UV protection.

Your best option is to bring your curtains to an optician. An optician can perform a simple test on sunglasses to determine the level of UV protection and usually runs the test for free.

100% protection against UVA and UVB rays, or UV400. Reputable retailers provide labels that are accurate with UV sunglasses, so you need to be able to detect if the pair you need provides maximum UV protection.

What to look for: 

If the beam from a UV light source causes the fibers to shine even after passing through the lens of the sunglasses, you know that the sunglasses do not provide adequate protection against UV radiation.

It is especially important to check your old sunglasses to make sure they keep your eyes healthy when you enjoy your time in the sun.
