Ray-Ban uses four various kinds of lenses for their sun shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and regular lenses, which we won’t talk about right here because there is nothing special about them (they just arrive in different colours).

B15 XLT Lens Ray-Ban B15 XLT lenses are brownish in color, block one hundred% of all UV rays and permit only fifteen% of the visible light to pass via them (that’s an 85% reduction!). These brown lenses also provide a bit more distinction by cutting down on the quantity of blue light, as opposed to a G15 lens (which is explained in the next paragraph). Blue light is extremely easily captured by the eye and has the impact of softening other colours that are harsher to our vision. In other phrases, by decreasing the quantity of blue mild, the differences between colors and brightness of objects are more pronounced.

G15 XLT Lens The G15 XLT lenses have the same qualities as the B15 XLT lenses nevertheless they’re of grayish/greenish colour. The G15 lens is the original aviator lens that the military asked for Ray-Ban to develop. The problem was to style a lens that was “color neutral” in other words, a lens that filters light like the human eye does. If you want a lens that offers a little less contrast in between colours, then the G15 XLT lens is for you because it provides comparable colour-sensitivity to the human eye. With a lower distinction lens, the difference in color and brightness of objects will be dampened. This indicates that the colours you see through these lenses will be natural and gentle on the eyes.

Each the B15 and G15 XLT lenses are made of influence resistant optical glass that is normally scratch resistant. Quality and balance are outstanding and more than time you will notice virtually no fading in any way in the color.

Polarized Lens Polarized lenses essentially cut down the amount of glare produced by reflective surfaces like water or other semi-clear objects, and even some metallic surfaces. Glare refers to the difficulty of seeing in vibrant light.

Daylight, for example, bounces off surfaces in all instructions (i.e. vertically, horizontally or diagonally). For individuals who are energetic in the “horizontal plane”, it indicates that the bright daylight bounced horizontally enters the eye in a comparable style. This leads to the pupils to constrict and considerably reduce contrast. That’s why drivers have problems seeing the street forward of them if they are driving in very sunny conditions (if the sun is ahead of them).

Polarized lenses have a laminated surface with vertical stripes that create a filter, which effectively cuts out the horizontally-polarized mild and enables only vertically-polarized mild in. In other words, if you occur to be on a distinct lake you can probably see under the surface or if you are driving, you can now see the street ahead.

Some restrictions to polarized lenses are that Lcd shows may turn out to be distorted or you may discover a “rainbow” impact if your car’s windows are tinted.
