What Type 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 won’t discuss here because there’s nothing 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 offer a bit more contrast by cutting down on the amount of blue light, as opposed to a G15 lens (which is described in the next paragraph). Blue light is very easily captured by the eye and has the effect of softening other colors that are harsher to our vision. In other words, by reducing 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 as the B15 XLT lenses; however they’re of grayish/greenish color. The G15 lens is the original aviator lens that the military requested Ray-Ban to develop. The challenge was to design a lens that was “color neutral”; in other words, a lens that filters light like the human eye does. If you want a lens that offers a little less contrast between colors, then the G15 XLT lens is for you because it offers similar color-sensitivity to the human eye. With a lower contrast lens, the difference in color and brightness of objects will be dampened. This means that the colors you see through these lenses will be natural and soft on the eyes.

Both the B15 and G15 XLT lenses are made of impact resistant optical glass that is naturally scratch resistant. Quality and stability are remarkable and over time you will notice virtually no fading whatsoever in the color.

Polarized Lens Polarized lenses essentially cut down the amount 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 light.

Sunlight, for example, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For people who are active in the “horizontal plane”, it means that the bright sunlight bounced horizontally enters the eye in a similar fashion. This causes the pupils to constrict and significantly reduce contrast. That’s why drivers have difficulty seeing the road ahead of them 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 create a filter, which effectively cuts out the horizontally-polarized light and allows only vertically-polarized light in. In other words, if you happen to be on a clear lake you can probably see under the surface or if you’re driving, you can now see the road ahead.

Some limitations to polarized lenses are that LCD displays may become distorted or you may notice a “rainbow” effect if your car’s windows are tinted.

Things To Look At For The Best Digital Camera

When you are looking are looking for the best value digital camera, there are a few things that need to be considered. Even though the price of the best value digital camera is the factor that people think about most often when it comes to value, that’s not the only thing. There are a few things that you should look at when you are looking for value in digital cameras, and we’ll go over them here.
One of the things that you should examine first is the digital camera’s resolution. This is going to be determined by the number of megapixels that it has. Choose a camera with more megapixels than less megapixels. You will get better quality pictures with more megapixels.
The next thing that you want to look at is the zoom lens. An important thing when looking for the best value digital camera is to know that you can see your subjects clearly even if they aren’t close to you. It’s really frustrating to miss a good picture due to the fact that you don’t have a decent zoom lens.
You should select a camera that has an LCD screen which is big. This is helpful in figuring out whether or not your picture or to redo it.
The next thing to think about when purchasing a digital camera is the weight of the camera. Even though it may not be at the top of your list when you are buying a digital camera, it might make a difference. It can be uncomfortable and you may end up losing some good pictures because you have to stop taking pictures to rest. So when you are comparing cameras, look at their weight as well as the other items that are listed.

Although people look at this first, usually, it should be the last thing to consider. You may find that your bargain camera isn’t a bargain without the other thing on the list being considered.
You need to consider a lot of thing when you are choosing the best value digital camera. But taking time to weigh the factors in equal portions and not factoring in price til the end will help you make a good choice. You may find that you paid a lot for a camera that you thought would be cheap because you didn’t choose wisely. You are going to find value in the time you take to carefully weigh the factors.
