AR lenses have  a specialized coating that is made of a microscopic layer of metal oxides that neutralize reflections, allowing it to minimize glare from the front and back surfaces of each lens. They aid in the transmission of light through the optical lens and into your eye.

Another advantage of AR coatings is that they make your glasses and eyes look better by nearly eliminating distracting reflections and glare that would otherwise bounce off your glasses.

AR coatings can also help prevent eye fatigue and digital eye strain. Your eyes don’t have to work as hard to capture a quality image since they get more light.

Anti-reflective coatings allow 99.5 percent of light to flow through the lens, compared to 92 percent for regular lenses.

For optimal clarity throughout the day, anti-reflective coatings can be applied to regular optical lenses as well as sunglasses.

Transmission tests are useful for measuring index homogeneity or thickness variation. In addition, they can be used to measure the power of a lens with low power. The Mach-Zehnder can also be used for testing surfaces in reflection by replacing one of the fold mirrors with the test part. The sensitivity is less since the beam is incident at 45° instead of normal incidence.

Anti-reflective (AR) eyeglass lenses reduce glare and reflections that are distracting and affect how well you see. That’s why anti-reflective coatings are one of the most popular lens choices among people who wear glasses.

Another common interferometer is the Mach-Zehnder, which is useful for testing optics in transmission in single pass. If the optic under test has large deviations, this less sensitive test could be better for keeping the wavefront slope within the dynamic range of the interferometer.

Without an AR coating, lenses have noticeable glare, which means light reflects off their surfaces, limiting the quantity of light traveling through the lens. This can make your vision less clear and lower your ability to detect contrasts, especially at night.
