Ray-Ban works by using 4 different types of lenses for their sun shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and normal lenses, which we won't go over below simply because you can find absolutely nothing special about them (They only occur in various colors).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block 100% of all UV rays and allow only 15% with the noticeable gentle to pass through them (that is an 85% reduction!). These brown lenses also offer a bit far more distinction by slicing down on the level of blue light-weight, as opposed to a G15 lens (that's explained in the subsequent paragraph). Blue gentle may be very effortlessly captured by the eye and has the effect of softening other colours which are harsher to our vision. To put it differently, by minimizing the quantity of blue mild, the variations involving colors and brightness of objects are more pronounced.

G15 XLT Lens

The G15 XLT lenses hold the identical Qualities because the B15 XLT lenses, having said that they're of greyish/greenish colour. The G15 lens is the original aviator lens the navy requested Ray-Ban to create. The challenge was to structure a lens which was "colour neutral"; Quite simply, a lens that filters mild just like the human eye does. If you want a lens which offers a little less distinction involving colours, then the G15 XLT lens is for yourself as it gives similar colour-sensitivity into the human eye. By using a reduce distinction lens, the main difference in colour and brightness of objects will be dampened. Consequently the colours the thing is via these lenses might be organic and tender about the eyes.

Both the B15 and G15 XLT lenses are made of impact resistant optical glass that is naturally scratch resistant. Quality and stability are amazing and as time passes you might discover almost no fading whatsoever within the colour.

Polarized Lens

Polarized lenses primarily Minimize down the quantity of glare produced by reflective surfaces like water or other semi-clear objects, as well as some metallic surfaces. Glare refers to the difficulty of looking at in dazzling light-weight.

Sunlight, for instance, bounces off surfaces in all Instructions (i.e. vertically, horizontally or diagonally). For people who find themselves active within the "horizontal plane", it ensures that the intense sunlight bounced horizontally enters the eye in a similar manner. This will cause the pupils to constrict and drastically decrease contrast. That is why drivers have problems viewing the street in advance of these when they're driving in pretty sunny problems (In the event the Solar is ahead of them).

Polarized lenses Use a laminated surface with vertical stripes that produce a filter, which correctly cuts out the horizontally-polarized light-weight and will allow only vertically-polarized light-weight in. To paraphrase, for those who materialize being on a clear lake you may most likely see under the area or if you're driving, Now you can see the street ahead.

Some limits to polarized lenses are that Liquid crystal display displays could grow to be distorted or chances are you'll see a "rainbow" outcome if your automobile's Home windows are tinted.

All 3 lenses are quite beneficial, specifically the polarized oneday colored contacts kinds, but be expecting to pay a high quality around the sun shades.

Lens Base

The lens foundation simply refers back to the foundation curve or even the entrance curve of the lens measured in "diopters", which is a expression that basically only matters to opticians. You will find that numerous Ray-Ban aviators have a "Lens Base 6", which mainly indicates that they're sufficiently curved and intended to to operate as sun shades (i.e., they address the eyes plenty of).

Lens Dimension

Lens measurement is calculated in millimeters and refers back to the length (or width) of one lens. Bear that in mind when building a purchase. Several Ray-Ban styles are available a number of distinct measurements of lens. Make sure you get the scale that matches your face or you could possibly end up getting a set of aviator shades that do not healthy appropriately.

Some Ray-Ban sunglasses have lens dimensions which are designated as added tiny, modest, and many others. This is often popular for products that don't resemble common Eyeglasses with two lenses. These sunglasses Have a very "uni-lens" layout, the place the lenses are linked seamlessly with the bridge. Because of this, conventional sizing isn't applicable. These shades are for just a superior vogue seem.
