Are these 100% original Ray-Ban?

NOT REAL 100% .. If your Ray-Ban sunglasses or not made in the USA they are not real RAY BANS sunglasses, they are simply a cheap knock off. The Ray-Ban sunglasses made in Italy are of inferior quality to the glasses that were previously made with strict quality control in the USA. In order for the company Luxo to produce, manufacture and sell, then ship sunglasses with the EXACT same QUALITY MATERIALS and QUALITY CONTROL as the original RAYBAN made in the USA sunglasses they would have to charge $ 350 to $ 450 a pair. So wise up and realize the actual but sad truth that the Italian made RAYBAN SUNGLASSES are unfortunately a cheap hoax.

Everything we sell is 100% authentic and 100% new. We buy direct from the manufacturer. These glasses are from The LUCOTTICA Group so we can make sure we only get the real deal. -The Star Eyewear Team

What is the difference between polarized and not?

Ray-BanG15XLTLensThe G15 XLTlenses have the same properties as the B15 XLT lenses, however they're of greyish/greenish color. If you want a lens that offers a little less contrast between colors, then the G15 XLT lens is for you because it offers similar color-sensitivity to the human eye. With a lower contrast lens, the difference in color and brightness of objects will be dampened. This means that the colors you see through these lenses will be natural and soft on the eyes.What'sthedifferencebetweenaB15XLTlensandaG15XLTlens?Both the B15 and G15 XLT lenses are made of impact resistant optical glass that is naturally scratch resistant. Quality and stability are remarkable and over time you will notice virtually no fading whatsoever in the color. This means that in terms of function, they're the same.The difference is in the color and what kind of contrast you're looking for when wearing sunglasses. If you're interested in more contrast, then go with a B15 lens. If you're interested in a more natural contrast between colors, then go with a G15 lens.Ray-BanPolarizedLensPolarized lenses essentially cut down the amount of glare produced by reflective surfaces like water or other semi-transparent objects, and even some metallic surfaces. Glare refers to the difficulty of seeing in bright light. Ray-Ban polarized lenses are of incredible quality.Sunlight, for example, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For people who are active in the "horizontal plane", it means that the bright sunlight bounced horizontally enters the eye in a similar fashion. This causes the pupils to constrict and significantly reduce contrast. That's why drivers have difficulty seeing the road ahead of them if they're driving in very sunny conditions (if the sun is ahead of them). Since there's no contrast, the eye can't distinguish between objects.Ray-Ban Polarized lenses have a laminated surface with vertical stripes that create a filter, which effectively cuts out the horizontally-polarized light and allows only vertically-polarized light in. In other words, if you happen to be on a clear lake you can probably see under the surface or if you're driving, you can now see the road ahead.Some limitations to polarized lenses are that LCD displays may become distorted or you may notice a "rainbow" effect if your car's windows are tinted.All 3 types of Ray-Ban lenses are very useful, particularly the polarized ones, but expect to pay a premium on the sunglasses. However, since Aviator Shades is an auction site, you'll probably find an incredible deal.LensBaseThe lens base simply refers to the base curve or the front curve of the lens measured in "diopters", which is a term that really only matters to opticians. You'll find that many Ray-Ban aviators have a "Lens Base 6", which basically means that they're sufficiently curved and designed to function as sunglasses. Some Ray-Ban aviator sunglasses are curved even more with a Lens Base of 8.LensSizeLens size is measured in millimetres and refers to the length (or width) of one lens. Bear that in mind when making a purchase. Many Ray-Ban aviator models come in several different sizes of lens. Ensure you get the size that fits your face or you may end up with a pair of aviator shades that don't fit properly... unless you're going for the bug-eyed look.Some Ray-Ban sunglasses have lens sizes that are designated as extra small, small, etc. This is common for models that do not resemble traditional glasses with two lenses. These sunglasses have a "uni-lens" design, where the lenses are connected seamlessly through the bridge. For this reason, traditional sizing is not applicable. These Ray-Ban shades are for a high fashion look.
