Ray-Ban makes use of four differing kinds of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and usual lenses, which we won't focus on listed here due to the fact there is certainly nothing at all Unique about them (They only appear in numerous colours).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block one hundred% of all UV rays and permit only 15% from the visible mild to pass through them (which is an 85% reduction!). These brown lenses also give a little bit far more distinction by slicing down on the quantity of blue mild, in contrast to a G15 lens (that's explained in the subsequent paragraph). Blue light is very quickly captured by the eye and has the outcome of softening other colours that happen to be harsher to our eyesight. Quite simply, by cutting down the amount of blue mild, the differences among colors and brightness of objects tend to be more pronounced.

G15 XLT Lens

The G15 XLT lenses hold the very same Houses because the B15 XLT lenses, even so they're of greyish/greenish colour. The G15 lens is the original aviator lens which the military services asked for Ray-Ban to produce. The problem was to design and style a lens that was "colour neutral"; in other words, a lens that filters light-weight similar to the human eye does. In order for you a lens that provides a little less distinction amongst colours, then the G15 XLT lens is to suit your needs because it presents related colour-sensitivity for the human eye. That has a decrease contrast lens, the primary difference in colour and brightness of objects is going to be dampened. Which means that the colors you see by these lenses will likely be natural and comfortable around the eyes.

Both of those the B15 and G15 XLT lenses are made of impression resistant optical glass that is naturally scratch resistant. Excellent and stability are outstanding and after some time grey lenses you'll detect practically no fading by any means in the colour.

Polarized Lens

Polarized lenses in essence cut down the amount of glare produced by reflective surfaces like drinking water or other semi-clear objects, as well as some metallic surfaces. Glare refers to The problem of observing in dazzling light.

Sunlight, by way of example, bounces off surfaces in all Instructions (i.e. vertically, horizontally or diagonally). For people who find themselves active inside the "horizontal aircraft", it signifies 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 trouble viewing the street ahead of them if they're driving in extremely sunny situations (In the event the Sunlight is ahead of them).

Polarized lenses have a laminated area with vertical stripes that make a filter, which correctly cuts out the horizontally-polarized light-weight and lets only vertically-polarized gentle in. Quite simply, in case you come about for being on a clear lake you are able to most likely see underneath the floor or should you be driving, you can now begin to see the street ahead.

Some limits to polarized lenses are that Liquid crystal display displays may perhaps develop into distorted or you could possibly recognize a "rainbow" effect if your automobile's windows are tinted.

All three lenses are incredibly helpful, significantly the polarized types, but expect to pay for a premium to the sunglasses.

Lens Foundation

The lens foundation just refers back to the base curve or perhaps the front curve on the lens measured in "diopters", that's a term that actually only issues to opticians. You'll find a large number of Ray-Ban aviators Possess a "Lens Base six", which essentially suggests that they're sufficiently curved and built to to operate as sunglasses (i.e., they protect the eyes enough).

Lens Measurement

Lens dimensions is calculated in millimeters and refers to the duration (or width) of one lens. Bear that in mind when generating a order. Several Ray-Ban types are available a number of distinct measurements of lens. Make sure you get the scale that matches your face or you could end up having a set of aviator shades that do not match effectively.

Some Ray-Ban sunglasses have lens measurements which might be specified as more compact, compact, etc. This really is frequent for versions that do not resemble conventional glasses with two lenses. These sun shades Have got a "uni-lens" design, where the lenses are related seamlessly in the bridge. Due to this, common sizing is not really relevant. These shades are for the substantial style appear.
