Are they even safer? Not exactly. While they do sharpen your vision in situations where glare can be distracting or even dangerous, they don't offer any additional protection from UV light. So in other words, they're not healthier for your eyes, but they do improve your vision for many outdoor activities.
Polarized light waves, on the other hand, are light waves in which the vibrations occur in a single plane. Polarized lenses transform these light waves (so they become polarized), and as a result less disturbing to your vision. Non-polarized lenses don't filter light in this way, so the glare is much more noticeable.
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.
Although gray and green lenses have their own benefits, and colorful lenses are fun, copper and amber tints increase contrast, making them the best options for driving. If you're looking for a crisp, clear view, we suggest finding a pair of shades with amber or copper lenses – and extra points if they're polarized.
Sunglasses with green lenses provide better contrast than gray lenses and transmit color accuracy better than brown lenses. Ideal for both sunny and low-light environments, green lenses have a way of reducing glare while brightening shadows.
When fixing scratches on polarized plastic lenses;
- Clean both sides of the two lenses with warm water and mild soap.
- Use a thin coat of petroleum jelly or scratch removing polish onto the entire lens.
- Rub the polish gently in a circular motion on the lens using a clean and dry microfiber cloth.
Only transverse waves can be polarised (or polarized in US English). Longitudinal waves cannot be polarised. Transverse: vibrations perpendicular to the direction of travel of the wave .
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.
UV protection protects your eyes from the dangerous rays of the sun while polarized sunglasses eliminate glare. Having ultraviolet protection is crucial while polarization is more of a preference. Polarized glasses do offer better image clarity but do not come with full UV protection.
Polarized : Ray-Ban® Polarized lenses not only reduce reflections, but also enhance contrast, improving visual clarity and reducing eye strain. All Ray-Ban® polarized lenses bear a distinctive “P” next to the Ray-Ban® logo on the right lens and are treated with Anti-Reflective coating.

What are Polarized Lenses? During the manufacturing process, a special chemical is applied to an eyeglass lens to polarize it. The chemical is laminated in a vertical pattern, which reorganizes light. This pattern blocks the light that is horizontal to eliminate glare, which is similar to how a window blind works.
Polarized sunglasses are usually more expensive, since they contain higher quality lenses that protect your eyes. You can think of this as an investment in your health! One Downside: Polarized lenses may reduce your visibility on LCD screens like ATMs, tablets, or phones.
Those little dots or lines you see are sections of the glass that partially polarize light on a horizontal axis. Since your polarized lenses have a vertical axis, that light is blocked, which is why it appears as dark dots or lines.
How to Choose the Best Sunglasses: Six Things to Consider
- Make it 100 percent. The single most important thing to look for when buying sunglasses to protect your eyes is a sticker or tag indicating that they block 100 percent of UV rays.
- Bigger is better.
- Darker lenses don't protect better.
- Color doesn't matter.
- Polarized lenses cut glare, not UV.
- Cost shouldn't be a factor.
Glasses to Avoid While Night DrivingUV and polarized glasses usually have a yellow or blue tint to them. Headlights and streetlights are not the same as sunlight, however, and these glasses may actually be dangerous to wear at night. Polarized and UV lenses just serve to block the light, not enhance it.
As we know, the polarized sunglasses just like the sunglasses protect our eyes from the strong sunlight and uv. However the coating part which adopts the special material may make you feel dizzy at first time of wearing. Because of the special design and perfect material, Polarized lenses can block 100% of glare.
Polarized lenses are not recommended for use in the aviation environment. While useful for blocking reflected light from horizontal surfaces such as water or snow, polarization can reduce or eliminate the Page 5 visibility of instruments that incorporate anti- glare filters.
Light also reflects off of the asphalt of many road surfaces. Polarized glasses can block some of the reflected light, reducing dangerous glare and making driving safer. This myth is completely true. The light is polarized in such a way that the polarized glasses can make it disappear entirely.
Oakley CollectorAccording to the AS/NZS1067:2003 standard, lenses are banned for use when driving if they provide "very high sunglare reduction", so the ban seems to be based on light transmission levels.
Generally the brighter the light, the darker the lenses will turn. Lenses that only react to UV light are not suitable for driving because car windscreens filter out UV, slowing and limiting the reaction of the lenses. You could find yourself driving with lenses too light as a result.
Don't worry - there's nothing wrong with your lenses or your eyes. The rainbows you see are actually strain patterns in the tempered glass windows. However, sunglasses with polarised lenses filter all light waves except vertical ones, allowing you to see the strain patterns in car side and rear windows.
Some Oakley Prizm lenses are polarized, meaning they include a filter to block glare from reflected light. Prizm lenses don't mean polarized—it's an entirely different lens technology. Whereas polarized lenses block glare from reflected light, Prizm lenses amplify what you're seeing.
Blue glasses are not suitable for driving, while yellow sunglass lenses are really good for sharpening up images, but causes more colour distortion. Brown lenses reduce glare sufficiently well, including absorbing the blue frequency of light in the sun's rays, which makes your surroundings seem hazy.
Clinical research has shown that FL-41 tinted glasses provide the most relief for chronic photophobia, offering extensive protection against fluorescent lighting and other bright sources.
