Ray-Ban utilizes four different types of lenses for his or her sun shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and standard lenses, which we won't discuss here for the reason that you will find nothing at all Distinctive about them (they just appear in various colours).
B15 XLT Lens
Ray-Ban B15 XLT lenses are brownish in colour, block one hundred% of all UV rays and permit only fifteen% in the obvious light to go through them (that's an eighty five% reduction!). These brown lenses also provide a bit a lot more contrast by reducing down on the amount of blue light, rather than a G15 lens (and that is explained in the following paragraph). Blue mild is incredibly easily captured by the attention and has the result of softening other colours which are harsher to our eyesight. To paraphrase, by reducing the amount of blue light, the variations among colours and brightness of objects are more pronounced.
G15 XLT Lens
The G15 XLT lenses have the same properties as the B15 XLT lenses, nevertheless They are of greyish/greenish colour. The G15 lens is the first aviator lens the navy requested Ray-Ban to create. The challenge was to structure a lens which was "colour neutral"; Basically, a lens that filters mild much like the human eye does. If you prefer a lens that provides a little less contrast among colours, then the G15 XLT lens is in your case as it presents related colour-sensitivity towards the human eye. Having a lower contrast lens, the difference in colour and brightness of objects are going to be dampened. Consequently the colors you see through these lenses will likely be purely natural and comfortable on the eyes.
Equally the B15 and G15 XLT lenses are created of effects resistant optical glass that is naturally scratch resistant. High-quality and balance are outstanding and eventually you'll detect virtually no fading in any respect during the colour.
Polarized Lens
Polarized colored contact lenses primarily Slice down the level of glare made by reflective surfaces like water or other semi-transparent objects, and in some cases some metallic surfaces. Glare refers to The issue of looking at in vibrant mild.
Sunlight, one example is, bounces off surfaces in all Instructions (i.e. vertically, horizontally or diagonally). For people who are active in the "horizontal airplane", it signifies that the intense sunlight bounced horizontally enters the eye in a similar fashion. This leads to the pupils to constrict and considerably reduce distinction. That is why motorists have problem viewing the highway forward of these whenever they're driving in extremely sunny conditions (Should the Sunlight is forward of these).
Polarized lenses Use a laminated surface with vertical stripes that develop a filter, which efficiently cuts out the horizontally-polarized light and lets only vertically-polarized mild in. In other words, in case you happen to get on a transparent lake you'll be able to probably see under the surface area or for anyone who is driving, Now you can begin to see the road ahead.
Some limitations to polarized lenses are that LCD displays may possibly turn into distorted or you may discover a "rainbow" impact if your car's windows are tinted.
All three lenses are very useful, especially the polarized ones, but expect to pay for a high quality within the sunglasses.
Lens Foundation
The lens base simply just refers to the foundation curve or even the entrance curve with the lens measured in "diopters", which is a expression that really only matters to opticians. You will discover that lots of Ray-Ban aviators Possess a "Lens Foundation six", which fundamentally indicates that they're adequately curved and made to to function as sun shades (i.e., they include the eyes plenty of).
Lens Dimension
Lens measurement is measured in millimeters and refers to the length (or width) of one lens. Bear that in mind when producing a invest in. Lots of Ray-Ban models come in many unique measurements of lens. Ensure you get the size that matches your face or you could end up with a pair of aviator shades that do not in good shape properly.
Some Ray-Ban sun shades have lens measurements that happen to be specified as further modest, tiny, and so on. This can be common for products that do not resemble conventional Eyeglasses with two lenses. These sunglasses Use a "uni-lens" layout, in which the lenses are related seamlessly from the bridge. Because of this, traditional sizing is not really applicable. These shades are for your higher vogue appear.
