Which is better UV or polarized sunglasses?
Key Takeaways. UV Blocking Sunglasses protect your eyes from dangerous ultraviolet rays and are crucial to good eye health. Polarized Sunglass Lenses can make your eyes more comfortable by eliminated glare.
Which sunglasses give the most protection?
Sunglasses with UV400 protection can filter out up to 99% of UVA and UVB rays. This is slightly higher than what British Standards require for eye protection, which makes them the best choice to ensure that your eyes are fully protected from sun damage.
How can I tell if my sunglasses are UV protected?
Most sunglasses today have UV protection embedded in the lens rather than coated over it, and most reputable brands list UV protection on their label. Look for a label that says “100% protection against both UVA and UVB” or “100% protection against UV 400.”
Is 100% UV protection the same as Polarised?
Polarization and UV Protection Are Not One and the Same
This is known as glare. Polarized lenses have a special filter that blocks intense reflected light for better visibility. Images seen through polarized lenses may appear a bit darker than normal, but objects should look clear and crisp.
What category sunglasses is best?
Category 2 lenses are the most common you will find in sunglasses. They provide good protection from UV rays but don’t have as dark a tint as the category 3 and 4 lenses. Category 3 lenses provide extra protection from UV light and will block out the majority of visible light to protect your eyes.
Do all sunglasses block UV?
Some inexpensive sunglasses still do not come with UVA/UVB protection. If sunglasses do not indicate such protection, don’t buy them. Wearing sunglasses without UVA/UVB protection can give a false sense of security, leading to irreversible sun damage.
How do I choose the right sunglasses?

Do all Ray Bans have UV protection?
All Ray-Ban lenses have UV protection, but the exact level varies among the types of lenses. Here’s what Ray-Ban offers: Classic lenses absorb 85% of visible light and block most blue light while providing a “natural vision” because they don’t alter the colors you see around you.
Do all polarized sunglasses have UV protection?
Polarized lenses and UV-protected lenses aren’t the same thing. So, it’s important to remember that polarized lenses don’t provide UV protection unless otherwise labeled. UV protection alone also doesn’t make a pair of sunglasses effective against reflected beams of light and glare.
What are the disadvantages of polarized sunglasses?
List of the Disadvantages of Polarized Lenses
- Polarized lenses make it difficult to view LCD screens.
- Polarized lenses can alter how you perceive the world.

Which is better UV400 or polarized?
UV400 protection provides our eyes with the highest level of protection. It blocks out 100% of all harmful light from the sun including harmful UV rays. Polarized lenses use a special film to further filter reflected light and reduce glare from smooth surfaces.
How much UV protection should sunglasses have?
100 percent
Sunglasses should have 100 percent protection from both UVB and UVA rays. Although UVB is known to be more harmful to skin and eyes, doctors suggest to avoid both types of rays. The lenses should also block UV wavelengths up to 400 nanometers.
How can I tell if my sunglasses are polarized?
Look at a bright, reflective light source (e.g., glass, water, or polished metal) with your shades on. If the light increases in intensity when you tilt your head sideways to around 60 degrees, you’re wearing polarized sunglasses. If there’s no change in quality, they’re just tinted.
Which sunglass color is best for eyes?
Dark colors (brown/gray/green) are ideal for everyday use and most outdoor activities. Darker shades are intended primarily to cut through the glare and reduce eyestrain in moderate-to-bright conditions. Gray and green lenses won’t distort colors, while brown lenses may cause minor distortion.
What color blocks the most UV rays?
Dark or bright colors, including red, black and navy blue, absorb more UV rays than lighter colors like whites and pastels.

If you find yourself squinting a lot, even when you’re wearing sunglasses, consider investing in polarized sunglasses.
What sunglasses do optometrists recommend?
