Ray-Ban makes use of four different types of lenses for their sun shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and typical lenses, which we can't go over in this article due to the fact there's very little Specific about them (They only come 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 fifteen% from the noticeable gentle to go through them (that is an eighty five% reduction!). These brown lenses also present you with a little bit far more distinction by cutting down on the level of blue mild, versus a G15 lens (which can be described in the subsequent paragraph). Blue gentle may be very easily captured by the eye and has the effect of softening other colours which can be harsher to our vision. To put it differently, by minimizing the quantity of blue gentle, the discrepancies involving colors and brightness of objects are more pronounced.

G15 XLT Lens

The G15 XLT lenses hold the identical Attributes given that the B15 XLT lenses, however They are of greyish/greenish colour. The G15 lens is the initial aviator lens the armed forces requested Ray-Ban to develop. The obstacle was to style and design a lens that was "colour neutral"; To put it differently, a lens that filters light like the human eye does. If you want a lens which offers a little less contrast involving colours, then the G15 XLT lens is for you personally mainly because it presents similar colour-sensitivity to the human eye. Which 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 smooth to the eyes.

Both the B15 and G15 XLT lenses are made of influence resistant optical glass that is of course scratch resistant. Good quality and balance are impressive and as time passes you can observe virtually no fading in any respect within the colour.

Polarized Lens

Polarized lenses fundamentally cut down the quantity of glare produced by reflective surfaces like drinking water or other semi-clear objects, and even some metallic surfaces. Glare refers to the difficulty of viewing in vivid gentle.

Daylight, such as, bounces off surfaces in all Instructions (i.e. vertically, horizontally or diagonally). For people who find themselves Energetic during the "horizontal airplane", it ensures that the intense sunlight bounced horizontally enters the eye in an analogous style. This brings about the pupils to constrict and appreciably reduce distinction. That's why motorists have difficulty seeing the road in advance of these should they're driving in pretty sunny conditions (if the sun is in advance of these).

Polarized lenses Use a laminated floor with vertical stripes that develop a filter, which properly cuts out the horizontally-polarized gentle and makes it possible for only vertically-polarized mild in. To put it differently, grey lenses should you take place to become on a transparent lake you can in all probability see beneath the surface or if you're driving, Now you can see the highway forward.

Some limitations to polarized lenses are that Liquid crystal display displays may perhaps become distorted or it's possible you'll detect a "rainbow" impact if your car's Home windows are tinted.

All three lenses are certainly beneficial, particularly the polarized types, but anticipate to pay for a top quality over the sunglasses.

Lens Foundation

The lens base only refers to the base curve or maybe the front curve with the lens measured in "diopters", and that is a term that actually only issues to opticians. You'll find that numerous Ray-Ban aviators Possess a "Lens Foundation six", which fundamentally usually means that they're sufficiently curved and built to to function as sunglasses (i.e., they protect the eyes enough).

Lens Measurement

Lens sizing is measured in millimeters and refers to the size (or width) of one lens. Bear that in your mind when earning a buy. Quite a few Ray-Ban models are available in many distinctive sizes of lens. Ensure you get the size that fits your confront or chances are you'll end up having a set of aviator shades that do not fit correctly.

Some Ray-Ban sunglasses have lens sizes which can be specified as further smaller, smaller, etcetera. This is common for designs that do not resemble traditional Eyeglasses with two lenses. These sun shades Use a "uni-lens" structure, where by the lenses are related seamlessly from the bridge. This is why, regular sizing will not be applicable. These shades are to get a higher fashion look.
