Ray-Ban employs four differing kinds of lenses for his or her sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and standard lenses, which we won't examine here mainly because there is certainly nothing Specific about them (They only come in different colors).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block 100% of all UV rays and allow only 15% with the obvious light to pass through them (that is an eighty five% reduction!). These brown lenses also give a little bit more contrast by reducing down on the quantity of blue gentle, versus a G15 lens (that is described in the next paragraph). Blue mild is incredibly easily captured by the attention and it has the result of softening other colours which have been harsher to our vision. To paraphrase, by minimizing the level of blue mild, the differences concerning colours and brightness of objects tend to be more pronounced.

G15 XLT Lens

The G15 XLT lenses possess the same Attributes since the B15 XLT lenses, nevertheless they're of greyish/greenish colour. The G15 lens is the first aviator lens which the navy requested Ray-Ban to build. The challenge was to layout a lens which was "colour neutral"; To paraphrase, a lens that filters gentle much like the human eye does. If you need a lens that offers rather less contrast between colors, then the G15 XLT lens is to suit your needs mainly because it features related colour-sensitivity for the human eye. Having a lessen contrast lens, the difference in colour and brightness of objects might be dampened. Which means the colors you see as a result of these lenses might be all-natural and tender within the eyes.

Both the B15 and G15 XLT lenses are made of effects resistant optical glass that is naturally scratch resistant. Excellent and stability are amazing and as time passes you can discover virtually no fading in any respect in the colour.

Polarized Lens

Polarized lenses in essence Slice down the level of glare made by reflective surfaces like h2o or other semi-clear objects, and also some metallic surfaces. Glare refers to The problem of looking at in bright mild.

Sunlight, one example is, bounces off surfaces in all Instructions (i.e. vertically, horizontally or diagonally). For people who find themselves Lively within the "horizontal plane", it implies that the intense sunlight bounced horizontally enters the eye in the same vogue. This results in the pupils to constrict and significantly decrease contrast. That's why drivers have difficulty seeing the road in advance of these should they're driving in pretty sunny disorders (if the Solar is in advance of these).

Polarized lenses Have a very laminated surface area with vertical stripes that produce a filter, which efficiently cuts out the horizontally-polarized light and makes it possible for only vertically-polarized light-weight in. To paraphrase, colored contacts for those who materialize being on a transparent lake you'll be able to almost certainly see under the area or for anyone who is driving, you can now begin to see the street ahead.

Some limits to polarized lenses are that LCD shows may possibly grow to be distorted or you might see a "rainbow" influence if your car's Home windows are tinted.

All 3 lenses are really valuable, especially the polarized kinds, but count on to pay for a top quality over the sunglasses.

Lens Foundation

The lens base basically refers to the base curve or maybe the front curve with the lens measured in "diopters", that's a term that actually only issues to opticians. You'll find that lots of Ray-Ban aviators Have got a "Lens Base 6", which mainly implies that they are sufficiently curved and designed to to function as sun shades (i.e., they go over the eyes adequate).

Lens Dimensions

Lens size is measured in millimeters and refers to the size (or width) of 1 lens. Bear that in your mind when making a obtain. Quite a few Ray-Ban models are available in many distinctive dimensions of lens. Ensure you get the size that fits your encounter or you could possibly end up getting a set of aviator shades that do not fit effectively.

Some Ray-Ban sunglasses have lens sizes which can be specified as further modest, smaller, etcetera. This is often common for models that don't resemble common Eyeglasses with two lenses. These sun shades Have a very "uni-lens" layout, the place the lenses are linked seamlessly throughout the bridge. For that reason, standard sizing just isn't relevant. These shades are to get a large style look.
