Types of Lenses Used by Ray-Ban

Ray-Ban makes use of 4 different types of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and regular lenses, which we won’t discuss right here since there’s nothing special concerning them (they just can be found in various colours) Ray Ban Aviators.

B15 XLT Lens

Ray-Ban B15 XLT lenses are brown in colour, block 100% of all UV rays and also permit only 15% of the visible light to go through them (that’s an 85% decrease!). These brownish lenses additionally offer a bit a lot more contrast by cutting down on the quantity of blue light, rather than a G15 lens (which is described in the next paragraph). Blue light is really easily caught by the eye and also has the result of softening various other colours that are harsher to our vision. In other words, by decreasing the quantity of blue light, the differences in between colours and also illumination of items are a lot more noticable.

G15 XLT Lens

The G15 XLT lenses have the very same buildings as the B15 XLT lenses, however they’re of greyish/greenish colour. The G15 lens is the original aviator lens that the army asked for Ray-Ban to create. The obstacle was to create a lens that was “colour neutral”; in other words, a lens that filters light like the human eye does. If you want a lens that offers a little much less comparison between colours, then the G15 XLT lens is for you since it offers similar colour-sensitivity to the human eye. With a reduced comparison lens, the difference in colour and also brightness of things will certainly be wetted. This indicates that the colours you see through these lenses will certainly be natural and soft on the eyes.

Both the B15 and G15 XLT lenses are constructed from impact immune optical glass that is normally scrape resistant. Quality and also security are amazing and also gradually you will discover virtually no fading whatsoever in the colour.

Polarized Lens

Polarized lenses basically reduced the amount of glow produced by reflective surfaces like water or other semi-transparent items, or even some metallic surfaces. Glare refers to the difficulty of seeing in intense light.

Sunlight, for example, jumps off surfaces in all instructions (i.e. vertically, flat or diagonally). For individuals who are energetic in the “horizontal plane”, it indicates that the bright sunlight jumped horizontally gets in the eye in a comparable style. This creates the students to constrict as well as substantially decrease comparison. That’s why drivers have problem seeing the road ahead of them if they’re driving in very warm conditions (if the sunlight leads them).

Polarized lenses have a laminated surface with vertical red stripes that develop a filter, which efficiently cuts out the horizontally-polarized light and also allows just vertically-polarized light in. In other words, if you occur to be on a clear lake you can probably see under the surface area or if you’re driving, you can now see the roadway ahead.

Some constraints to polarized lenses are that LCD screens could come to be altered or you may see a “rainbow” result if your cars and truck’s windows are tinted.

All 3 lenses are really helpful, especially the polarized ones, yet anticipate to pay a premium on the sunglasses.

Lens Base

The lens base simply refers to the base curve or the front curve of the lens measured in “diopters”, which is a term that really only matters to opticians. You’ll discover that lots of Ray-Ban pilots have a “Lens Base 6”, which generally means that they’re adequately curved and also designed to operate as sunglasses (i.e., they cover the eyes sufficient).

Lens Dimension

Lens dimension is gauged in millimeters and also describes the size (or size) of one lens. Bear that in mind when buying. Numerous Ray-Ban models can be found in a number of different dimensions of lens. Guarantee you obtain the dimension that fits your face or you could wind up with a pair of aviator shades that do not fit properly.

Some Ray-Ban sunglasses have lens sizes that are designated as extra small, little, and so on. This is common for models that do not appear like typical glasses with two lenses. These sunglasses have a “uni-lens” style, where the lenses are attached effortlessly with the bridge. For this reason, typical sizing is not applicable. These shades are for a haute couture look.
