Ray-Ban takes advantage of 4 different types of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and regular lenses, which we cannot examine below simply because there is certainly very little special about them (They only occur in several colours).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block 100% of all UV rays and permit only 15% from the visible light-weight to pass through them (which is an 85% reduction!). These brown lenses also offer a little bit a lot more distinction by slicing down on the amount of blue light-weight, in contrast to a G15 lens (which can be explained in the following paragraph). Blue light is quite easily captured by the eye and it has the impact of softening other colors that happen to be harsher to our vision. Quite simply, by decreasing the level of blue light, the discrepancies among colours and brightness of objects are more pronounced.

G15 XLT Lens

The G15 XLT lenses provide the same Qualities as being the B15 XLT lenses, nevertheless they're of greyish/greenish colour. The G15 lens is the original aviator lens that the navy requested Ray-Ban to produce. The problem was to style and design a lens which was "colour neutral"; Quite simply, a lens that filters mild like the human eye does. If you would like a lens which offers a little less contrast between colors, then the G15 XLT lens is for yourself because it offers similar colour-sensitivity into the human eye. Which has a decrease contrast lens, the primary difference in colour and brightness of objects is going to be dampened. Because of this the colors the thing is by means of these lenses will probably be natural and soft to the eyes.

Each the B15 and G15 XLT lenses are created of impact resistant optical glass that is of course scratch resistant. Quality and steadiness are impressive and over time you may notice just about no fading whatsoever while in the colour.

Polarized Lens

Polarized lenses fundamentally Slash down the level of glare made by reflective surfaces like drinking water or other semi-transparent objects, as well as some metallic surfaces. Glare refers to The problem of seeing in shiny light.

Daylight, for instance, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For people who find themselves active inside the "horizontal airplane", it signifies that the intense daylight bounced horizontally enters the eye in an analogous vogue. This brings about the pupils to constrict and substantially reduce distinction. That's why motorists have problems observing the road forward of these when they're driving in very sunny ailments (In case the Solar is forward of these).

Polarized lenses colored contact lenses Have got a laminated surface area with vertical stripes that develop a filter, which successfully cuts out the horizontally-polarized gentle and enables only vertically-polarized mild in. To paraphrase, in the event you come about to generally be on a transparent lake you can almost certainly see beneath the floor or if you're driving, Now you can begin to see the street forward.

Some restrictions to polarized lenses are that LCD shows might grow to be distorted or chances are you'll observe a "rainbow" outcome if your automobile's Home windows are tinted.

All 3 lenses are extremely handy, notably the polarized kinds, but be expecting to pay a premium over the sun shades.

Lens Foundation

The lens base simply just refers back to the base curve or perhaps the front curve in the lens calculated in "diopters", which can be a time period that really only matters to opticians. You will find that many Ray-Ban aviators Have a very "Lens Foundation six", which fundamentally usually means that they're sufficiently curved and intended to to operate as sun shades (i.e., they address the eyes adequate).

Lens Dimensions

Lens sizing is calculated in millimeters and refers back to the duration (or width) of 1 lens. Bear that in your mind when earning a obtain. Quite a few Ray-Ban models can be found in quite a few diverse dimensions of lens. Make sure you get the dimensions that fits your face or you might end up with a pair of aviator shades that don't in shape appropriately.

Some Ray-Ban sunglasses have lens dimensions that happen to be specified as added little, small, etcetera. This is certainly widespread for versions that don't resemble classic 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 isn't applicable. These shades are for your higher vogue glimpse.
