What sort of 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 will never discuss here because nothing at all is 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 move through them (that's an 85% reduction!). These brown lenses also provide bit more contrast by cutting regarding the regarding blue light, as opposed to a G15 lens (which is described in another paragraph). Blue light can be very easily captured by the interest rate and uses the effect of softening other colors which have been harsher to the vision. Consist of words, by reducing the quantity blue light, the differences between colors and brightness of objects are more pronounced. G15 XLT Lens The G15 XLT lenses have the same properties when compared to the B15 XLT lenses; however they're of grayish/greenish colouring material. The G15 lens is consumers are aviator lens that the military requested Ray-Ban to assemble. The challenge ended up being design a lens that was 'color neutral'; in other words, a lens that filters light like the human eye has been doing. If you here are a few lens providing a little less contrast between colors, then the G15 XLT lens ideal for you considering that it offers similar color-sensitivity to the human perspective. With a lower contrast lens, the difference in color and brightness of objects will be dampened. It indicates that the shades you look out of these lenses will be natural and soft close to eyes. Both the B15 and G15 XLT lenses made of impact resistant optical glass that is naturally scratch resistant. Quality and stability are remarkable and occasion you will notice virtually no fading whatsoever in shade. Polarized Lens Polarized lenses essentially decrease the involving glare that is caused by reflective surfaces like water or other semi-transparent objects, and even some metallic surfaces. Glare refers on the difficulty of seeing in bright pale. Sunlight, for example, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For market . are from the 'horizontal plane', it helps to ensure that the bright sunlight bounced horizontally enters the eye in the exact same fashion. This causes the pupils to constrict and significantly reduce compare. That's why drivers have difficulty seeing the trail ahead consultants 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 horizontally-polarized light and allows only vertically-polarized light living in. In other words, if someone happens to be on a distinct lake could possibly probably see under the surface or when you are driving, you'll be able to now are conscious of the road beforehand. Some limitations to polarized lenses are that LCD displays can get distorted anyone may notice a 'rainbow' effect if vehicle's windows are tinted. All 3 lenses tend to be very useful, in particular the polarized ones, but be ready to pay a premium on the sunglasses. Lens Base The lens base simply refers on the base curve or the front curve of this lens measured in 'diopters', which is often a term that really only matter to opticians. You'll recognize many Ray-Ban aviators have a 'Lens Base 6', which basically radically, and they're sufficiently curved and designed to function as sunglasses (i.e., watercraft the eyes enough). Lens Size Lens size is measured in millimeters and refers to the length (or width) of one lens. Bear that idea when creating a purchase. Many Ray-Ban models come several different sizes of standard zoom lens. Ensure you obtain the size that fits your face or nicely end lets start work on a set of aviator shades that don't fit right. Some Ray-Ban sunglasseshave lens sizes are generally designated as extra small, small, etc. This is common for models that do not resemble traditional glasses with two contacts. These sunglasses possess a 'uni-lens' design, where the lenses are connected seamlessly through the bridge. To do this reason, traditional sizing isn't applicable. These shades are for a good fashion research.
