Ray-Ban uses four various kinds of lenses for his or her shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and normal lenses, which we will not discuss here due to there being nothing special about the subject (they simply are available in different colours).

Ray-Ban B15 XLT lenses are brown in colour, block 100% of Ultra violet sun rays and permit only 15% from the visible light to feed them (that's an 85% reduction!). These brown lenses offer a little more contrast by cutting lower on the quantity of blue light, instead of a G15 lens (that is described within the next paragraph).

Blue light is extremely easily taken through the eye and it has the result of softening other colours which are harsher to the vision. Quite simply, by reduction of the quantity of blue light, the variations between colours and brightness of objects tend to be more pronounced.

The G15 XLT lenses have a similar qualities because the B15 XLT lenses, however they are of greyish/green colour. The G15 lens may be the original aviator lens the military requested Ray-Ban to build up.

The task ended up being to design a lens which was "colour neutral" quite simply, a lens that filters light such as the eye does. If you prefer a lens that provides rather less contrast between colours, then your G15 XLT lens is perfect for you since it offers similar colour-sensitivity towards the eye. Having a lower contrast lens, the main difference in occhiali donna rayban colour and brightness of objects is going to be dampened. Which means that the shades the thing is with these lenses is going to be natural and soft around the eyes.

Both B15 and G15 XLT lenses are constructed with impact-resistant optical glass that's naturally scratch resistant. Quality and stability are outstanding and also over time you will observe without any fading whatsoever within the colour.

Polarized lenses basically cut lower the quantity of glare created by reflective surfaces like water or any other semi-transparent objects, as well as some metallic surfaces. Glare refers back to the impossibility of seeing in vibrant light.

Sunlight, for instance, bounces off surfaces everywhere (i.e. vertically, horizontally or diagonally). For those mixed up in "horizontal plane", this means the vibrant sunlight bounced horizontally enters the attention similarly. This will cause the pupils to tighten and considerably reduce contrast. This is exactly why motorists have a problem seeing the street in front of them if they are driving in very sunny conditions (when the sun is in front of them).

Polarized lenses possess a laminated surface with vertical stripes that induce a filter, which effectively reduces the horizontally-polarized light and enables only vertically-polarized light in. Quite simply, if you perform a obvious lake you are able to most likely see underneath the surface or maybe you are driving, now you can begin to see the road ahead.

Some limitations to polarized lenses are that LCD displays can become distorted or if you notice a "rainbow" effect in case your car's home windows are tinted.

The lens base simply refers back to the base curve or even the front curve from the lens measured in "diopters", that is a term that actually only matters to opticians. You will find that many Ray-Ban aviators possess a "Lens Base 6", which essentially implies that they are sufficiently curved and made to operate as shades (i.e., they cover your eyes enough).
