What does UV400 mean on sunglasses?

Optimal UV protection

The UV400 label guarantees that the sunglasses block 100% of UV light, including both UVA and UVB rays. This protection is essential to prevent both short-term and long-term eye damage from prolonged sun exposure.

Reduced eye strain

Sunglasses with UV400 not only protect against direct UV rays, but also reduce the amount of reflected light. This reduces strain on the eye muscles and increases comfort, making them suitable for both leisure activities and sports.

Tested and documented quality

It is important to choose sunglasses that have been proven to be UV400-tested. Many fashion glasses simply offer decorative UV protection that does not provide the necessary blocking of harmful UV radiation.

Choose sunglasses with documented UV400 for reliable and effective protection for your eyes.
