UV400 sunglasses: what they are and why they matter
All OWEИ sunglasses have UV400 protection.
UV400 sunglasses filter ultraviolet radiation up to 400 nanometres, a range that includes the sun’s UVA and UVB rays. This protection helps reduce your eyes’ exposure to UV radiation when you are outdoors.
What does UV400 mean?
When choosing sunglasses, look for a clear UV400 label or a statement that they block 99–100% of UVA and UVB rays.
UV protection and lens tint are different features. Colour alone cannot tell you how much protection a pair provides.
Why is it important to wear sunglasses with UV protection?
UV exposure can affect the tissues of the eyes. Over time, it is associated with conditions such as cataracts. Making UV-protective sunglasses part of your outdoor routine is a simple way to care for your eyes.
Frequently asked questions about UV400 sunglasses
Do darker lenses offer more protection?
A dark lens can reduce the visible light you perceive, but that does not guarantee better UV protection. Always check the lens information, whether the lenses are black, brown, lightly tinted or mirrored.
What is the difference between UV400 and polarised sunglasses?
UV protection filters ultraviolet radiation. Polarisation reduces certain reflections, such as glare from water or roads.
Sunglasses can combine both features, but being polarised does not guarantee UV400 protection. Check each specification separately.
Do I need sunglasses in winter or on cloudy days?
UV radiation is present throughout the year and can pass through clouds. Water, sand and snow also reflect it. That is why protection matters beyond summer, especially when you spend time outdoors.
How to choose your next pair
- Look for clear information about the lenses’ UV protection.
- Choose a comfortable frame that stays in place and covers your eyes well.
- Remember that UV radiation can enter from the sides; a wide-brimmed hat can complement your sunglasses.
- If you are unsure about sunglasses you already own, an optician can check their UV protection.
