Ray-Ban utilizes 4 different types of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and usual lenses, which we can't talk about below simply because you will find absolutely nothing Distinctive about them (They only appear in numerous colors).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block a hundred% of all UV rays and allow only fifteen% of your seen light to go through them (that is an 85% reduction!). These brown lenses also give a bit more contrast by chopping down on the quantity of blue gentle, in contrast to a G15 lens (and that is explained in the following paragraph). Blue light-weight is rather effortlessly captured by the eye and it has the impact of softening other colors which are harsher to our vision. In other words, by minimizing the level of blue light-weight, the variances concerning colors and brightness of objects tend to be more pronounced.

G15 XLT Lens

The G15 XLT lenses possess the very same Houses as the B15 XLT lenses, nonetheless they're of greyish/greenish colour. The G15 lens is the original aviator lens that the army requested Ray-Ban to build. The challenge was to design and style a lens that was "colour neutral"; To put it differently, a lens that filters mild such as the human eye does. If you need a lens that provides a little less distinction concerning colors, then the G15 XLT lens is in your case as it gives equivalent colour-sensitivity for the human eye. Having a reduce distinction lens, the main difference in colour and brightness of objects will likely be dampened. Because of this the colors you see by means of these lenses will likely be natural and comfortable on the eyes.

Equally the B15 and G15 XLT lenses are created of impact resistant optical glass that is naturally scratch resistant. Good quality and security are extraordinary and with time you might notice practically no fading in any respect from the colour.

Polarized Lens

Polarized lenses effectively Slash down the level of glare produced by reflective surfaces like water or other semi-clear objects, and perhaps some metallic colored lenses surfaces. Glare refers to The issue of observing in vivid gentle.

Sunlight, as an example, bounces off surfaces in all Instructions (i.e. vertically, horizontally or diagonally). For people who are Energetic while in the "horizontal plane", it signifies that the brilliant sunlight bounced horizontally enters the attention in the same style. This triggers the pupils to constrict and substantially decrease distinction. This is exactly why motorists have issues seeing the street in advance of them whenever they're driving in extremely sunny disorders (In case the sun is forward of these).

Polarized lenses have a laminated floor with vertical stripes that make a filter, which efficiently cuts out the horizontally-polarized light-weight and enables only vertically-polarized light-weight in. In other words, in case you happen to become on a clear lake it is possible to likely see under the surface or in case you are driving, you can now begin to see the highway forward.

Some restrictions to polarized lenses are that LCD shows may well develop into distorted or it's possible you'll see a "rainbow" influence if your vehicle's Home windows are tinted.

All 3 lenses are extremely useful, significantly the polarized types, but anticipate to pay for a top quality over the sunglasses.

Lens Foundation

The lens foundation only refers to the foundation curve or the front curve of your lens measured in "diopters", which happens to be a phrase that actually only issues to opticians. You'll find a large number of Ray-Ban aviators have a "Lens Base 6", which mainly implies that they're adequately curved and meant to to operate as sun shades (i.e., they include the eyes ample).

Lens Dimensions

Lens sizing is calculated in millimeters and refers back to the size (or width) of one lens. Bear that in mind when producing a acquire. Quite a few Ray-Ban styles are available several various sizes of lens. Make sure you get the dimensions that fits your confront or chances are you'll end up getting a pair of aviator shades that do not suit correctly.

Some Ray-Ban sun shades have lens measurements which are selected as further little, compact, and many others. This can be typical for styles that do not resemble regular Eyeglasses with two lenses. These sunglasses Use a "uni-lens" style, where by the lenses are connected seamlessly from the bridge. For this reason, classic sizing is not applicable. These shades are for the superior fashion search.
