Compare polarised and non-polarised sunglasses for UV protection, glare reduction, and everyday use. Find out which type suits your needs best.
Quick answer
Choose polarised sunglasses for glare-free driving and water sports; pick non-polarised for clear phone screens and low-light conditions.
Why lens type matters more than you think
The main difference between polarised and non-polarised sunglasses is how they handle glare. Polarised lenses use a special filter that blocks horizontal light waves, which cuts glare from flat surfaces like roads, water, or snow. Non-polarised lenses simply darken everything equally without filtering glare.
Both types can offer UV protection, so the choice isn't about safety—it's about what you do in the sun. If you spend time near reflective surfaces, polarised lenses reduce eye strain. If you frequently check your phone or drive with a heads-up display, non-polarised lenses keep screens readable.
What about UV protection?
UV protection depends on the lens coating, not whether the lens is polarised. You can find polarised and non-polarised sunglasses that block 99% of UVA and UVB rays. For example, the Premium Polarised Sunglasses - Mens include UV400 coating that blocks up to 99% of UVA and UVB rays, plus a category 3 filter for glare reduction. Non-polarised options with similar UV ratings exist but won't filter glare.
Polarised vs Non-Polarised: The Trade-Offs
- Polarised sunglasses: Best for reducing glare from water, roads, and snow. Ideal for driving, fishing, skiing, and beach days. However, they can make LCD screens (phones, car dashboards) harder to read and may cause depth-perception issues in some users.
- Non-polarised sunglasses: Best for everyday wear where glare isn't an issue. They allow clear visibility of digital screens and won't distort depth perception. But they do not reduce glare, so they are less comfortable in bright, reflective environments.
- UV protection is not the deciding factor: Both types can offer UV400 protection. Check the label for 'UV400' or '100% UV protection' regardless of polarisation. Polarisation adds glare reduction, not extra UV blocking. Always verify UV protection separately from polarisation.
