Ray-Ban utilizes 4 differing kinds of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and ordinary lenses, which we cannot focus on listed here for the reason that there's nothing Particular about them (they just appear in various colours).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block 100% of all UV rays and permit only 15% on the seen light to go through them (that's an 85% reduction!). These brown lenses also give a little bit more contrast by slicing down on the level of blue gentle, versus a G15 lens (that is described in another paragraph). Blue gentle is extremely quickly captured by the eye and has the effect of softening other colors which have been harsher to our eyesight. Basically, by lessening the quantity of blue gentle, the dissimilarities among colours and brightness of objects tend to be more pronounced.

G15 XLT Lens

The G15 XLT lenses hold the identical Attributes as being the B15 XLT lenses, nonetheless they're of greyish/greenish colour. The G15 lens is the first aviator lens that the military services requested Ray-Ban to develop. The problem was to design a lens that was "colour neutral"; Basically, a lens that filters light-weight such as the human eye does. If you prefer a lens that provides a little less distinction between colors, then the G15 XLT lens is for you personally since it delivers related colour-sensitivity towards the human eye. That has a decreased distinction lens, the primary difference in colour and brightness of objects will probably be dampened. Which means the colours the thing is by means of these lenses will likely be pure and soft on the eyes.

Both the B15 and G15 XLT lenses are created of affect resistant optical glass that is naturally scratch resistant. Top quality and stability are amazing and with time you will observe almost no fading in any respect during the colour.

Polarized Lens

Polarized lenses fundamentally Reduce down the level of glare made by reflective surfaces like water or other semi-transparent objects, and also some metallic surfaces. Glare refers to The issue of looking at in vivid light.

Sunlight, by way of example, bounces off surfaces in all Instructions (i.e. vertically, horizontally or diagonally). For people who are Lively in the "horizontal airplane", it means that the brilliant daylight bounced horizontally enters the attention in an identical vogue. This leads to the pupils to constrict and substantially lessen contrast. That is why drivers have issue looking at the street ahead of these when they're driving in really sunny ailments (If your Sunlight is ahead of them).

Polarized lenses have a laminated surface with vertical stripes that develop a filter, which efficiently cuts out the horizontally-polarized light and lets only vertically-polarized light-weight in. Basically, should you occur being on a clear lake you could most likely see beneath the surface or should you be driving, Now you can begin to see the highway forward.

Some limits to polarized lenses are that Liquid crystal display shows may develop into distorted or you might recognize a "rainbow" influence if your vehicle's windows are tinted.

All 3 lenses are incredibly valuable, specially the polarized types, but assume to pay a top quality about the sunglasses.

Lens Base

The lens foundation only refers back to the base curve or perhaps the front curve from the lens calculated in "diopters", and that is a expression that really only issues to opticians. You will discover a large number of Ray-Ban aviators Possess a "Lens Foundation 6", which mainly suggests that they're sufficiently curved and made to to operate as sun shades (i.e., they include the eyes enough).

Lens Dimensions

Lens size is calculated in millimeters and refers to the length (or width) of one lens. Bear that in mind when generating a purchase. Quite a few Ray-Ban designs can be found in various different sizes of lens. Ensure you get the size that fits your confront or it's possible you'll end up having a set of aviator shades that don't healthy appropriately.

Some Ray-Ban sunglasses have lens sizes that are selected as more compact, compact, etcetera. This is often colored contact prevalent for styles that do not resemble traditional glasses with two lenses. These sun shades Possess a "uni-lens" design, where by the lenses are linked seamlessly in the bridge. For that reason, common sizing is not really relevant. These shades are for any high trend look.
