Does 100% UVA UVB mean polarized?
No. “100% UVA/UVB protection” and “polarized” describe two different features. UVA/UVB protection refers to how well the lens blocks harmful ultraviolet radiation, while polarization refers to how the lens reduces glare from reflective surfaces like water, snow, or pavement.
What 100% UVA/UVB protection actually means
When sunglasses say they provide 100% UVA/UVB protection (sometimes shown as “UV400”), it means the lenses are designed to block ultraviolet rays that can contribute to eye damage over time. This protection is about safety for your eyes, not visual comfort in bright reflections.
What polarized lenses actually do
Polarized lenses include a special filter that cuts horizontally reflected light, which is the type of glare that can make it harder to see clearly while driving or spending time around water. Polarization can improve visual clarity and reduce eye strain in high-glare environments, but it does not automatically tell you anything about UV protection unless the label also states UV blocking.
Why the two labels get confused
Many high-quality sunglasses offer both features, so shoppers often see “100% UVA/UVB” and assume polarization is included. The only reliable way to confirm polarization is to look for “polarized” on the product listing, lens tag, or specifications.
How to check if a pair is polarized
If product details aren’t clear, check the packaging or the retailer’s specs for the word “polarized.” In person, you can also do a quick test by looking at an LCD screen (like a phone) and rotating the sunglasses—polarized lenses often darken the screen at certain angles.

FAQ
Is UV400 the same as 100% UVA/UVB protection?
Usually, yes. UV400 typically means the lenses block UV rays up to 400 nanometers, which covers both UVA and UVB. Still, it’s best to confirm the label explicitly states 100% UVA/UVB or UV400 from a trusted seller.
