Ray-Ban employs 4 different types of lenses for his or her sun shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and ordinary lenses, which we won't examine in this article mainly because there is absolutely nothing Distinctive about them (They simply arrive in several colours).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block one hundred% of all UV rays and allow only 15% on the seen gentle to pass through them (that's an eighty five% reduction!). These brown lenses also offer a little bit extra distinction by slicing down on the level of blue gentle, rather than a G15 lens (that's described in the next paragraph). Blue light-weight is rather simply captured by the attention and has the influence of softening other colours that are harsher to our vision. In other words, by cutting down the amount of blue gentle, the variations between colours and brightness of objects are more pronounced.

G15 XLT Lens

The G15 XLT lenses have the very same Attributes because the B15 XLT lenses, even so They are of greyish/greenish colour. The G15 lens is the first aviator lens that the navy requested Ray-Ban to establish. The obstacle was to design a lens which was "colour neutral"; Quite simply, a lens that filters light-weight just like the human eye does. If you would like a lens that offers rather less contrast among colours, then the G15 XLT lens is for you mainly because it features very similar colour-sensitivity to your human eye. Which has a decrease contrast lens, the primary difference in colour and brightness of objects might be dampened. Which means the colours you see through these lenses are going to be normal and delicate on the eyes.

Both equally the B15 and G15 XLT lenses are made of impression resistant optical glass that is naturally scratch resistant. Excellent and stability are amazing and as time passes you can recognize pretty much no fading in any way during the colour.

Polarized Lens

Polarized lenses primarily Slice down the level of glare made by reflective surfaces like drinking water or other semi-transparent objects, and in many cases some metallic surfaces. Glare refers to The problem of observing in shiny gentle.

Daylight, such as, bounces off surfaces in all Instructions (i.e. vertically, horizontally or diagonally). For people who are Lively in the "horizontal aircraft", it implies that the bright daylight bounced horizontally enters the eye in an analogous trend. This leads to the pupils to constrict and significantly lower contrast. This is why drivers have issue viewing the highway ahead of these if they're driving in incredibly sunny situations (if the Sunshine is in advance of them).

Polarized lenses Use a laminated area with vertical stripes that produce a filter, which correctly cuts out the horizontally-polarized light and lets only vertically-polarized light-weight in. Quite simply, if you come about to generally be on a transparent lake you'll be able to in all probability see underneath the floor or if you're driving, Now you can begin to see the street forward.

Some restrictions to polarized lenses are that LCD displays might grow to be distorted or you could possibly observe a "rainbow" influence if your vehicle's windows are tinted.

All three lenses are certainly valuable, notably the polarized ones, but expect to pay for a premium on the sunglasses.

Lens Foundation

The lens base simply just refers to the foundation curve or even the entrance curve from the lens calculated in "diopters", which is a phrase that basically only issues to opticians. You'll find that lots of Ray-Ban aviators Have got a "Lens Base 6", which in essence implies that they are adequately curved and made to to function as sunglasses (i.e., they cover the eyes ample).

Lens Size

Lens measurement is calculated in millimeters and refers back to the size (or width) of 1 lens. Bear that in your mind when making a acquire. Numerous Ray-Ban types are available a number of diverse measurements of lens. Ensure you get the size that fits your face oneday colored contacts or you could end up getting a pair of aviator shades that do not fit properly.

Some Ray-Ban sun shades have lens measurements which can be designated as more modest, little, etc. This is often widespread for versions that don't resemble standard Eyeglasses with two lenses. These sunglasses Use a "uni-lens" style, where by the lenses are linked seamlessly in the bridge. This is why, standard sizing is not applicable. These shades are for your higher vogue appear.
