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.
Polarized Shades Keep You on Top of Your Game
While the goal of UV-blocking lenses is to protect your eyes, the point of polarized lenses is to remove glare so you can see more clearly and easily, i.e., less squinting!
'UV400' refers to UV rays at the top end of the UV spectrum, up to the 400-nanometre wavelength. Sunglasses with this level of protection block an even wider spectrum than the CE and British Standard models, making them the ultimate protection for your eyes.
For maximum protection that prevents wrinkles and UV damage to your eyes and surrounding skin, polarised UV400 wraparound shades are the way to go.
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.

Polarization has nothing to do with UV light absorption, but many polarized lenses are now combined with a UV-blocking substance. Check the label to make sure the lenses provide maximum UV protection. The same goes for lens color and tint, lens darkness, and mirror coating.
When it comes down to it, the question of UV vs. polarized lenses is simple. They are two completely different things. While UV protection sunglasses protect your eyes from harmful sun rays, polarized lenses reduce the glare that causes you to squint in the sunlight.
Polarized sunglasses aren't any better at protecting your eyes from UV light than regular UV lenses, but they can make it easier for you to see. They do this by blocking horizontal light waves—the type that most surfaces reflect when causing a glare.
The answer lies within the numbered rating, and the highest UV protection rating offered is UV 400. According to the American Academy of Ophthalmology, you should choose sunglasses that block 99% to 100% of UVA and UVB rays, and UV 400-protected sunglasses do this.
Is UV400 good for eyes?
UV400 Lenses
Both are harmful to our eyes, which is why sunglasses are essential. Short-term overexposure to these days can lead to 'photokeratitis'- a type of sunburn to the outer layer of the cornea that can happen after spending too much time at high altitudes with limited sun protection (like during snow sports).
For protection, says the American Academy of Ophthalmology, wear sunglasses that block 99 to 100 percent of both UVA and UVB rays.
The biggest disadvantage of polarized sunglasses is their effect on LCD screens. Polarized sunglasses can make LCD screens hard to view due to the way that the lenses filter light. Screens can become extremely dark or even completely blank at some angles when viewed through polarized lenses.
To be considered UV sunglasses, the lenses are required to block 75% to 90% of visible light and must offer UVA and UVB protection to block 99% of ultraviolet radiation. Ideally, you want sunglasses that offer UV 400 protection since they offer virtually 100% protection from UV rays.
Total Protection
Investing in sunglasses that are labeled UV400 blocks 99 to 100 percent of UV light. This rating ensures that all light rays with wavelengths up to 400 nanometers, including both UVA and UVB rays, are blocked out.
0–19% VLT: Ideal for bright, sunny conditions. 20–40% VLT: Good for all-purpose use. 40+% VLT: Best for overcast and low-light conditions. 80–90+% VLT: Virtually clear lenses for very dim and night conditions.
Oakley is known for its high-quality lenses and advanced performance technology, and the Turbine Polarized Sunglasses are no exception. These sunglasses feature Plutonite lens material, which filters out 100 percent of UVA, UVB, and UVC. Better yet, they protect against blue light from devices, too.
1. Ray-Ban. It's no surprise that Ray-Ban is the top pick for the best sunglasses brands in the world. After all, this heritage powerhouse has been making very high-quality, stylish sunglasses for more than 80 years — its Aviator-style shades were originally designed for military use but went “public” in 1937.
There is no definitive expiration date on when your sunglasses begin to lose effectiveness since everybody spends a different amount of time in the sun. It depends on the individual. If it's an everyday pair, they may only last a year or two before needing replacement.
Polarized sunglasses are worth it if they meet your lifestyle needs. They're excellent if you spend time outdoors, live in a snowy climate, or drive a lot. If you're looking for a pair of polarized sunglasses, remember to ensure they have 99 to 100% UV protection to prevent damage to your eyes.
Does polarized mean anti glare?
Both polarized lenses and anti-reflective lenses enhance vision clarity by managing distracting glare, though each has a different purpose and use. Simply put: Polarized lenses minimize glare in bright, sunny, outdoor settings. Anti-reflective lenses minimize glare in dim lighting indoors and at night.
Polarized lenses will not protect your eyes from UV damage more than standard 100% UV lenses. However, they can give you clearer, more accurate vision and alleviate some eye strain. If you find yourself squinting a lot, even when you're wearing sunglasses, consider investing in polarized sunglasses.
Polarized lenses are sometimes suitable for driving during the day, but wearing them at night can be dangerous. The darkened lens makes it harder to see in low-light situations, which can be made worse if you already have trouble seeing at night.
Ultraviolet Eye Protection Matters
UV400 protection — which is to nearly 100 percent protection from harmful ultraviolet rays — can protect your precious peepers for a lifetime. Investing in sunglasses that are labeled UV400 blocks 99 to 100 percent of UV light.
Look for sunglasses that offer 100% UV protection from all UV light (UVA and UVB) or 100% protection against UV 400. If you are uncertain about an older pair of sunglasses, check the level of protection they offer by taking them to an optical shop with a UV light meter.
Blue or purple lenses are both fashion-savvy and practical for UV protection. While the blue tint enhances the contours around objects and improves color perception, it also can have a calming effect on the eyes.
UV400 Blocks all UV rays from 100 to 400 nm (UVA, UVB plus UVC). BUT THEY DO NOT PROTECT AGAINST BLUE LIGHT (HEV = 400 to 500 nm), which is suspected of being 30% responsbile for Macular Degeneration.
Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth's surface. Medium-wavelength UVB is very biologically active but cannot penetrate beyond the superficial skin layers.
The answer lies within the numbered rating, and the highest UV protection rating offered is UV 400. According to the American Academy of Ophthalmology, you should choose sunglasses that block 99% to 100% of UVA and UVB rays, and UV 400-protected sunglasses do this.
Polarized sunglasses are worth it if they meet your lifestyle needs. They're excellent if you spend time outdoors, live in a snowy climate, or drive a lot. If you're looking for a pair of polarized sunglasses, remember to ensure they have 99 to 100% UV protection to prevent damage to your eyes.
Which UV ray is the strongest?
A: UVC radiation is the highest energy portion of the UV radiation spectrum. UVC radiation from the sun does not reach the earth's surface because it is blocked by the ozone layer in the atmosphere.
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.”
Polarized lenses are sometimes suitable for driving during the day, but wearing them at night can be dangerous. The darkened lens makes it harder to see in low-light situations, which can be made worse if you already have trouble seeing at night.
While polarized glasses do offer protection from added UV rays, they also have the added benefit of reducing glare. Some glasses may protect from UV rays while not reducing glare.
It's a common myth that polarized lenses have to be expensive than traditional styles, they actually don't. Fuse Lenses makes replacement lenses for your name brand sunglasses. If you have a pair of Oakley's or Ray Bans, but want them to be polarized, you don't have to drop hundreds of dollars on a new pair!
If you spend a lot of time on the road, on the golf course, on the water or in the mountains, polarized lenses are a good investment. They reduce harmful (and annoying) glare on reflective surfaces like pavement and water, making objects appear clearer—like a golf ball, highway lines or a trail deep in the woods.
The main types of UV rays that can affect your skin include UVA rays and UVB rays. UVB rays have more energy and are a more potent cause of at least some skin cancers, but both UVA and UVB rays can damage skin and cause skin cancer. There are no safe UV rays.
In general, shorter wavelength UV works best for brighter fluorescence. Longer wavelengths (400 nm and higher) tend to produce purple and violet light, reducing the strength of the fluorescence effect. As a result, 365 nm has been the most popular UV wavelength among our customers.
