Which kind Of Lens Is Rayban Using On Their Sunglasses?
Ray-Ban uses four different types of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and normal lenses, which we can't discuss here because nothing seems special about them (they just come in different colors).
B15 XLT Lens
Ray-Ban B15 XLT lenses are brownish in color, block 100% of all UV rays and allow only 15% of the visible light to pass through them (that's an 85% reduction!). These brown lenses also suggest to a bit more contrast by cutting concerning the regarding blue light, as opposed to a G15 lens (which is described in the other paragraph). Blue light is fairly easily captured by the interest and maintain a pool of effect of softening other colors that are harsher for your vision. Some other words, by reduction of the amount of blue light, the differences between colors and brightness of objects are more pronounced.
G15 XLT Lens
The G15 XLT lenses have the same properties since your B15 XLT lenses; however they're of grayish/greenish shading. The G15 lens may be the original aviator lens how the military requested Ray-Ban to improve. The challenge were to design a lens that was 'color neutral'; in other words, a lens that filters light like our eye conducts. If you want a lens that gives a little less contrast between colors, then the G15 XLT lens great you simply because offers similar color-sensitivity towards human eye. With a lower contrast lens, some time in color and brightness of objects will be dampened. Nowadays . that the shades you see through these lenses will be natural and soft around eyes.
Both the B15 and G15 XLT lenses are formulated of impact resistant optical glass that is naturally scratch resilient. Quality and stability are remarkable additionally time you will notice practically no fading whatsoever in eliminating.
Polarized lenses essentially lessen the level of glare produced by reflective surfaces like water or other semi-transparent objects, and even some metallic surfaces. Glare refers to the difficulty of seeing in bright thin.
Sunlight, for example, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For individuals who are mixed up in the 'horizontal plane', it signifies that the bright sunlight bounced horizontally enters the eye in similar fashion. This causes the pupils to constrict and significantly reduce compare. That's why drivers experience difficulty seeing the road ahead regarding if they're driving in very sunny conditions (if the sun is ahead of them).
Polarized lenses have a laminated surface with vertical stripes that make a filter, which effectively cuts the actual horizontally-polarized light and allows only vertically-polarized light regarding. In other words, for happen end up being on a certain lake you probably see under top or for anybody who is driving, may get now understand the road send.
Some limitations to polarized lenses are that LCD displays can turn into distorted anyone may notice a 'rainbow' effect if your car's windows are tinted.
All 3 lenses incredibly useful, in particular the polarized ones, but expect you'll pay reasonably limited on the sunglasses.
The lens base simply refers towards base curve or best curve within the lens measured in 'diopters', which is really a term indeed only matter to opticians. You'll find out that many Ray-Ban aviators have a 'Lens Base 6', which basically means that they're sufficiently curved and designed to operate as sunglasses (i.e., they cover the eyes enough).
Lens dimensions are measured in millimeters and refers into the length (or width) 1 lens. Bear that to mind when making an acquisition. Many Ray-Ban models are useful several sizes of scope. Ensure you get product . that fits your face or you could potentially end up with an associated with aviator shades that don't fit rightly.
Some Ray-Ban sunglasseshave lens sizes will be designated as extra small, small, etcetera. This is common for models that not resemble traditional glasses with two lenses. These sunglasses have a 'uni-lens' design, where the lenses are connected seamlessly through the bridge. For this reason, traditional sizing isn't applicable. These shades are for a superior fashion look.
