Ray-Ban uses four several types of lenses for shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and normal lenses, which we won't discuss here because of there being nothing special regarding the subject (they just can be found in different colours).

Ray-Ban B15 XLT lenses are brown in colour, block 100% of Ultra purple sun sun rays and enable only 15% in the visible light to give them (that's an 85% reduction!). These brown lenses offer a bit more contrast by cutting lower on the amount of blue light, rather of the G15 lens (that's described over the following paragraph). Blue light is very easily taken with the eye and contains caused by softening other colours that are harsher towards the vision. Basically, by decrease in the amount of blue light, the variations between colours and brightness of objects tend to be pronounced.

The G15 XLT lenses have the identical characteristics since the B15 XLT lenses, however are of greyish/eco-friendly ray ban esagonali. The G15 lens could be the original aviator lens the military requested Ray-Ban to develop. The job would have been to design a lens that was "colour neutral" basically, a lens that filters light like the eye does.

If you need a lens that gives less contrast between colours, your G15 XLT lens is ideal for you because it offers similar colour-sensitivity for the eye. Getting a lesser contrast lens, the primary improvement in colour and brightness of objects will probably be dampened. Meaning the colors the factor is by using these lenses will probably be natural and soft about the eyes.

Both B15 and G15 XLT lenses are built with impact-resistant optical glass that's naturally scratch resistant. Quality and stability are outstanding well as over time you will see with no fading whatsoever inside the colour.

Polarized lenses essentially cut lower the amount of glare produced by reflective surfaces like water or other semi-transparent objects, plus some metallic surfaces. Glare means impracticality of seeing in vibrant light.

Sunlight, for example, bounces off surfaces everywhere (i.e. vertically, horizontally or diagonally). For individuals involved in the "horizontal plane", what this means is the colourful sunlight bounced horizontally enters the interest similarly. This makes the pupils to then significantly reduce contrast. This is why motorists have trouble seeing the road before them if they're driving in very sunny conditions (once the sun is before them).

Polarized lenses have a very laminated surface with vertical stripes that creates a filter, which effectively cuts down on the horizontally-polarized light and enables only vertically-polarized light in. Basically, should you execute a apparent lake you'll be able to probably see beneath the surface or you are driving, you can now start to see the road ahead.

Some limitations to polarized lenses are that LCD displays may become distorted or you watch a "rainbow" effect in situation your car's home home windows are tinted.

The lens base simply means base curve or perhaps the front curve in the lens measured in "diopters", that's a term that really only matters to opticians. You will notice that many Ray-Ban aviators have a very "Lens Base 6", which basically implies that they're sufficiently curved making to function as shades (i.e., they cover your vision enough).
