Ray-Ban B15 XLT lenses are brownish in colour, block one hundred% of all UV rays and allow only 15% from the obvious gentle to pass through them (which is an 85% reduction!). These brown lenses also offer a little bit more distinction by chopping down on the quantity of blue mild, instead of a G15 lens (which can be described in the subsequent paragraph). Blue mild is extremely very easily captured by the attention and has the effect of softening other colors that happen to be harsher to our vision. Basically, by lowering the level of blue light, the distinctions involving colors and brightness of objects tend to be more pronounced.

G15 XLT Lens

The G15 XLT lenses have the identical Qualities given that the B15 XLT lenses, on the other hand They are of greyish/greenish colour.

For people who are active within the "horizontal plane", it ensures that the intense sunlight bounced horizontally enters the attention in a similar trend. This results in the pupils to constrict and considerably minimize contrast. That is why drivers have problem viewing the highway forward of these whenever they're driving in extremely sunny conditions (If your sun is forward of these).

Polarized lenses have a laminated floor with vertical stripes that make a filter, which correctly cuts out the horizontally-polarized mild and will allow only vertically-polarized light in. To paraphrase, should you materialize to become on a clear lake you could almost certainly see beneath the floor or when you are driving, Now you can begin to see the highway forward.

Some restrictions to polarized lenses are that LCD displays may turn out to be distorted or you could possibly detect a "rainbow" influence if your vehicle's windows are tinted.

All three lenses are really practical, significantly the polarized types, but anticipate to pay for a premium over the sunglasses.
