Ray-Ban takes advantage of 4 different types of lenses for his or her sun shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and typical lenses, which we can't talk about below since there's practically nothing Distinctive about them (they just arrive in several colors).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block 100% of all UV rays and allow only 15% on the obvious light to pass through them (that's an 85% reduction!). These brown lenses also give a little bit extra distinction by cutting down on the amount of blue mild, rather than a G15 lens (which happens to be explained in another paragraph). Blue light-weight is extremely very easily captured by the eye and has the impact of softening other colours which can be harsher to our vision. Quite simply, by cutting down the quantity of blue gentle, the discrepancies concerning colors and brightness of objects are more pronounced.

G15 XLT Lens

The G15 XLT lenses possess the identical Qualities because the B15 XLT lenses, nonetheless they're of greyish/greenish colour. The G15 lens is the first aviator lens which 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 amongst colours, then the G15 XLT lens is for yourself as it gives similar colour-sensitivity into the human eye. By using a reduced distinction lens, the main difference in colour and brightness of objects will probably be dampened. Therefore the colours the thing is by means of these lenses will be pure and gentle over the eyes.

The two the B15 and G15 XLT lenses are created of influence resistant optical glass that is of course scratch resistant. Quality and security are remarkable and after a while you will observe pretty much no fading in any way from the colour.

Polarized Lens

Polarized lenses basically Minimize down the level of glare produced 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, such as, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For people who are active inside the "horizontal aircraft", it signifies that the intense daylight bounced horizontally enters the attention in the same manner. This causes 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 conditions (When the sun is in advance of these).

Polarized lenses Use a laminated floor with vertical stripes that produce a filter, which efficiently cuts out the horizontally-polarized mild and enables only vertically-polarized light in. In other words, if you materialize to generally be on a transparent lake you'll be able to almost certainly see under the area or for anyone who is driving, you can now begin to see the street ahead.

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

All 3 lenses are really valuable, especially the polarized kinds, but count on to pay for a premium over the sunglasses.

Lens Foundation

The lens foundation just refers back to the base curve or perhaps the entrance curve on the lens calculated in "diopters", which can be a time period that actually only issues to opticians. You will discover that lots of Ray-Ban aviators Have got a "Lens Base 6", which gray lenses mainly implies that they are adequately curved and made to to function as sun shades (i.e., they address the eyes adequate).

Lens Dimensions

Lens size is measured in millimeters and refers to the size (or width) of 1 lens. Bear that in your mind when making a buy. A lot of Ray-Ban products come in numerous diverse dimensions of lens. Make sure you get the scale that matches your face or you could end up getting a pair of aviator shades that don't suit appropriately.

Some Ray-Ban sun shades have lens measurements that happen to be selected as more compact, small, etc. This really is typical for versions that do not resemble conventional Eyeglasses with two lenses. These sun shades Use a "uni-lens" style and design, where by the lenses are linked seamlessly from the bridge. For that reason, classic sizing just isn't applicable. These shades are for a superior manner glance.
