AR coating is especially beneficial on high-index lenses. These lenses are thinner and lighter than regular plastic lenses. They can reflect up to 50% more light than regular plastic lenses so less light reaches your eyes.

The exact formula of anti-reflective coating depends on the company that makes it. In general, AR coating is made of many very thin layers of metal oxides that are applied to the lens surface. The layers alternate between high and low refractive indexes (the refractive index measures how the lens refracts — or bends — light). The more layers there are, the less amount of light that’s reflected onto the lenses of your anti-glare glasses.

The majority of lenses with anti-reflective coating have a very light tint, which is usually green or blue. The color depends on the brand of coating that’s on your lenses.

Most premium AR lenses include a surface treatment to seal the anti-reflective layers and make the lenses easier to clean. These treatments also repel water so you won’t get water spots on your lenses. Some lens surface treatments repel both water and oil from your skin.

Anti-reflective coating has many benefits, but it is an add-on so your anti-glare glasses will cost more. If you’re considering it, talk to your eye doctor so they can help you decide if it’s worth it for you.

The more light that reaches your eyes, the better you can see. Anti-reflective coating (also called “AR coating” or “anti-glare coating”) decreases the amount of light that is reflected off the front and back surfaces of your eyeglass lenses. This lets more light pass through the lenses and reach your eyes.

Most regular plastic lenses reflect about 8% of the light hitting the lenses so only 92% of available light enters the eyes. AR coating eliminates almost all reflections so up to 99% of light passes through your anti-glare glasses and reaches your eyes.

Light is critical for good vision. When light enters your eye, it hits the retina — the light-sensitive layer of tissue at the back of the eye. Photoreceptors cells in the retina turn the light into electrical signals. Those cells send the electrical signals to the optic nerve, and the optic nerve sends them to the brain. The brain turns those signals into the things you see.

We have developed a low-noise digital camera based on a 512 x 96 element CCD operating in the time-delay integration mode. This camera has been combined with an x-ray image intensifier to record radiographic images produced by a scanning slot beam of radiation. This results in the rejection of a large fraction of scattered radiation, without a significant increase in x-ray tube heat loading or image acquisition time. Here we describe the design of our CCD camera and the results of our investigations of camera resolution, linearity, noise, and quantum efficiency. We have found that both the resolution limit (50 mm-1) and the dynamic range (2100) of this novel camera are greater than reported values for conventional video cameras. Applications of this system in digital angiography and mammography are discussed.
