What are polarized lenses and how do they work?

Polarized lenses contain a chemical filter that blocks horizontal light waves - the kind that create blinding glare off water, snow, roads, and glass. The result is sharper contrast, reduced eye strain, and clearer vision in bright conditions. Every Kraywoods frame comes fitted with TAC polarized lenses as standard.

Polarized vs non-polarized sunglasses - which should I choose?

Polarized lenses are worth it whenever glare is an issue: driving, water sports, skiing, or any time you're outdoors in bright sun. Non-polarized lenses still block UV light but won't cut reflected glare. For regular outdoor use, polarized is the better choice.

What does UV400 protection mean?

UV400 means the lenses block all ultraviolet light up to 400 nanometres - covering both UVA and UVB rays. This is the highest standard of UV protection available in sunglasses. All Kraywoods polarized lenses meet UV400.

Q: How do you test if your sunglasses are polarized?

Hold your lenses up to a reflective surface - like a phone screen or window - and rotate them 90 degrees. If the reflection darkens or disappears at a certain angle, the lenses are polarized. You can also look through two pairs at once and rotate one: if the view goes dark when they're perpendicular, both are polarized.

Q: Do polarized lenses affect touchscreen or LCD screen visibility?

Some LCD screens can appear darker or tinted when viewed through polarized lenses - especially at certain angles. This is a known optical effect and not a defect. Simply tilt the device or your head slightly if needed.

Q: How do I care for polarized sunglasses?

Wipe lenses with the included microfibre cloth - avoid paper towels or clothing fibres which can scratch coatings. Rinse frames with clean water after salt or chlorine exposure. Store in the included protective case when not in use. Avoid leaving frames in a hot car, which can warp acetate and wood.

¿Qué son las gafas de sol polarizadas?

Polarized sunglasses are sunglasses with lenses that contain a chemical filter built into the lens itself. The filter blocks horizontal light waves that cause glare from reflective surfaces like water, roads, snow, and glass. The result is sharper contrast, reduced eye strain, and clearer vision in bright outdoor conditions.

How do polarized sunglasses work?

Polarized sunglasses work by filtering light waves at the molecular level. Sunlight scatters in every direction, but when it bounces off a flat surface like water, pavement, or a car hood, it organizes into horizontal waves that hit the eye as glare. The polarized filter in the lens blocks those horizontal waves while letting vertical light pass through, eliminating glare without darkening your overall view.

What is the difference between polarized and non-polarized sunglasses?

Polarized sunglasses block glare from reflective surfaces; non-polarized sunglasses do not. Both lens types block UV rays, but only polarized lenses filter the horizontal light waves that cause glare from water, snow, roads, and glass. Non-polarized sunglasses simply darken your view. Polarized lenses sharpen contrast and reduce eye strain in bright conditions, which makes them especially valuable for driving, outdoor sport, and time near water.

Polarized vs UV protection — which matters more?

You need both, and Kraywoods polarized sunglasses include both as standard. UV protection blocks invisible UVA and UVB rays that damage the eye over time. Polarization filters visible glare from reflective surfaces to sharpen what you see in the moment. UV protects long-term eye health; polarization improves daily visual comfort. Neither replaces the other.

Are polarized sunglasses worth it?

Polarized sunglasses are worth it if you drive often, spend time near water or snow, or struggle with glare in bright conditions. Polarized lenses cut reflective glare in a way that non-polarized lenses simply cannot, and they reduce the eye strain that builds up across a day in the sun. For most outdoor wearers, the upgrade pays back in daily visual comfort.

When should I wear polarized sunglasses?

Wear polarized sunglasses anytime glare is a problem. Driving in bright sun, time on or near water, snow conditions, beach days, and outdoor activity all benefit from polarization. Polarized lenses are less useful in low light or indoor conditions, and some shoppers find them tricky for reading LCD screens. For everyday outdoor wear, polarized is the stronger choice.

Can you wear polarized sunglasses for night driving?

Polarized sunglasses are not recommended for night driving. The polarized filter reduces overall light reaching the eye, which can make low-light conditions harder to see clearly. Polarized lenses are also tinted, which compounds the issue after dark. For night driving, untinted prescription glasses with anti-reflective coating are the right tool.

Do polarized lenses affect phone screens or LCD displays?

Yes, sometimes. Some LCD screens can appear darker, tinted, or rainbow-patterned when viewed through polarized lenses, especially at certain angles. This is a known optical effect, not a defect. It does not affect your ability to use the device — simply tilt the device or your head slightly to clear the effect.

How do I test if my sunglasses are polarized?

Hold the lenses up to a reflective surface like a phone screen or a window and rotate them 90 degrees. If the reflection darkens or disappears at a certain angle, the lenses are polarized. You can also look through two polarized pairs at once and rotate one — when they cross perpendicular to each other, the view turns dark.

Can I get polarized sunglasses with prescription lenses?

Yes. Every Kraywoods sunglasses frame can be made with prescription lenses, and polarization is one of two lens protection options at checkout. To order, select your frame, tap "Select Lenses" on the product page, and choose your prescription type, tint, and polarization. Every order is reviewed by our certified in-house optician before production.

How should I care for polarized sunglasses?

Use the microfiber cloth and hard case that come with every Kraywoods order. Wipe lenses with a mild lens cleaner or warm water; avoid alcohol, ammonia, or abrasive cloths, which can dull the lens coating. Rinse frames with clean water after salt or chlorine exposure, and avoid leaving them in a hot car, which can warp wood or acetate.
