Varieties of Lenses Utilized by Ray-Ban

Ray-Ban utilizes 4 differing types of lenses for his or her sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and usual lenses, which we won't examine here due to the fact there's almost nothing special about them (They simply appear 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 obvious gentle to pass through them (that is an eighty five% reduction!). These brown lenses also give a little bit far more contrast by chopping down on the level of blue gentle, rather than a G15 lens (that's described in the subsequent paragraph). Blue light-weight is very effortlessly captured by the eye and has the influence of softening other colors which have been harsher to our eyesight. In other words, by lessening the amount of blue light-weight, the discrepancies between colours and brightness of objects tend to be more pronounced.

G15 XLT Lens

The G15 XLT lenses have the exact same Qualities because the B15 XLT lenses, nevertheless They are of greyish/greenish colour. The G15 lens is the original aviator lens that the army asked for Ray-Ban to develop. The problem was to design a lens which was "colour neutral"; To paraphrase, a lens that filters gentle such as human eye does. If you want a lens that provides rather less contrast concerning colors, then the G15 XLT lens is for yourself as it delivers similar colour-sensitivity on the human eye. That has a decrease contrast lens, the primary difference in colour and brightness of objects are going to be dampened. Consequently the colours you see via these lenses will be pure and soft on the eyes.

Equally the B15 and G15 XLT lenses are created of affect resistant optical glass that is of course scratch resistant. Quality and stability are impressive and after a while you can observe virtually no fading in any way from the colour.

Polarized Lens

Polarized lenses basically Minimize down the level of glare made by reflective surfaces like water or other semi-transparent objects, and in many cases some metallic surfaces. Glare refers to The issue of seeing in brilliant gentle.

Daylight, for example, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For people who are active while in the "horizontal plane", it ensures that the intense daylight bounced horizontally enters the eye in the same vogue. This results in the pupils to constrict and considerably minimize contrast. That is why drivers have problems viewing the road ahead of these should they're driving in very sunny circumstances (In case the Solar is ahead of them).

Polarized lenses Use a laminated floor with vertical stripes that produce a filter, which proficiently cuts out the horizontally-polarized gentle and lets only vertically-polarized gentle in. To paraphrase, in the event you transpire for being on a clear lake it is possible to almost certainly see under the area or for anyone who is driving, you can now see the road in advance.

Some constraints to polarized lenses are that LCD shows could turn out to be distorted or you may see a "rainbow" influence if your car's Home windows are tinted.

All 3 lenses are really valuable, especially the polarized ones, but hope to pay a high quality within the sun shades.

Lens Base

The lens foundation merely refers back to the base curve or perhaps the front curve with the lens measured in "diopters", and that is a phrase that really only issues to opticians. You will find that many Ray-Ban aviators Use a "Lens Base 6", which basically usually means that they're sufficiently curved and created to to function as sunglasses (i.e., they go over the eyes plenty of).

Lens Dimensions

Lens sizing daliy contacts is calculated in millimeters and refers back to the size (or width) of one lens. Bear that in your mind when making a order. Many Ray-Ban products are available various diverse measurements of lens. Make sure you get the scale that matches your experience or it's possible you'll end up with a pair of aviator shades that don't in good shape correctly.

Some Ray-Ban sun shades have lens sizes that are designated as additional little, tiny, and so forth. That is widespread for styles that don't resemble classic glasses with two lenses. These sunglasses have a "uni-lens" design, where the lenses are related seamlessly in the bridge. Due to this, common sizing will not be relevant. These shades are for any large fashion look.
