Kinds of Lenses Used by Ray-Ban

Ray-Ban makes use of four different types of lenses for their sun shades. The B15 XLT lens, the G15 XLT lens, polarized lenses and regular lenses, which we can't talk about below since you can find nothing at all Distinctive about them (they just arrive in several colors).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block a hundred% of all UV rays and allow only 15% on the obvious light-weight to pass through them (that's an 85% reduction!). These brown lenses also give a little bit more contrast by cutting down on the amount of blue mild, in contrast to a G15 lens (which happens to be explained in the next paragraph). Blue light-weight is extremely very easily captured by the eye and has the result of softening other colours which might be harsher to our vision. Quite simply, by cutting down the level of blue gentle, the discrepancies involving colors and brightness of objects are more pronounced.

G15 XLT Lens

The G15 XLT lenses possess the identical Qualities because the B15 XLT lenses, nonetheless they're of greyish/greenish colour. The G15 lens is the first aviator lens which the military asked for Ray-Ban to acquire. The problem was to layout a lens that was "colour neutral"; in other words, a lens that filters light-weight similar to the human eye does. In order for you a lens that provides rather less distinction in between colors, then the G15 XLT lens is in your case since it offers identical colour-sensitivity on the human eye. Using a lower contrast lens, the difference in colour and brightness of objects are going to be dampened. Which means the colours the thing is via these lenses will be normal and gentle to the eyes.

Each the B15 and G15 XLT lenses are created of impact resistant optical glass that is naturally scratch resistant. High-quality and balance are extraordinary and after some time you may notice almost no fading in anyway inside the colour.

Polarized Lens

Polarized lenses fundamentally cut down the quantity of glare made by reflective surfaces like h2o or other semi-clear objects, as well as some metallic surfaces. Glare refers to The problem of observing in dazzling light.

Sunlight, for example, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For people who are Energetic while in the "horizontal aircraft", it signifies that the brilliant daylight bounced horizontally enters the attention in an analogous manner. This causes the pupils to constrict and considerably minimize contrast. That is why drivers have trouble viewing the road ahead of these should they're driving in very sunny conditions (if the sun is in advance of them).

Polarized lenses Possess a laminated surface area with vertical stripes that create a filter, which successfully cuts out the horizontally-polarized light and allows only vertically-polarized light-weight in. Basically, when you transpire to get on a clear lake you can probably see underneath the surface area or in case you are driving, Now you can see the highway forward.

Some limitations to polarized lenses are that Liquid crystal display displays may perhaps develop into distorted or you could possibly recognize a "rainbow" effect if your vehicle's windows are tinted.

All three lenses are extremely practical, notably the polarized ones, but be expecting to pay a high quality within the sun shades.

Lens Base

The lens base simply refers to the foundation curve or the front curve of the lens measured in "diopters", which happens to be a phrase that basically only matters to opticians. You will find that a lot of Ray-Ban aviators Have got a "Lens Base 6", which mainly implies that they are adequately curved and made to to function as sun shades (i.e., they address the eyes adequate).

Lens Dimensions

Lens size is measured in millimeters and refers to the size (or width) of 1 lens. Bear that in your mind when earning a buy. A lot of Ray-Ban products come in a number of diverse dimensions of lens. Make sure you get the scale that matches your experience or chances are you'll end up having a set of aviator shades that do not in good shape properly.

Some colored contact Ray-Ban sunglasses have lens sizes which are designated as added tiny, modest, and many others. This is certainly popular for products that don't resemble regular Eyeglasses with two lenses. These sunglasses Possess a "uni-lens" style, in which the lenses are connected seamlessly through the bridge. For this reason, traditional sizing is not relevant. These shades are for the substantial style appear.
