The Benefits of Anti-Reflective Coating
After knowing some basic information about anti-reflective coating, you need to know the benefits of anti-reflective glasses.
Anti-reflective glasses enable more light to pass through your lenses to optimize visual acuity with fewer distractions and the lenses look nearly invisible, which enhances your appearance by drawing more attention to your eyes and helping you make better eye contact with others.
In addition, the anti-reflective coating is especially beneficial when used on high-index lenses, which reflect more light than regular lenses. That is to say, the higher the index of refraction of the lens material, the more light that will be reflected from the surface of the lenses.
What’s more, the modern anti-reflective coatings can reduce the reflection of light from eyeglasses, allowing 99.5% of available light to pass through the lenses and enter the eye for good vision.
Because the anti-reflective coating can eliminate the reflections, it can also make your eyeglass lenses look nearly invisible so that people can see your eyes and facial expressions more clearly. Hence, anti-reflective glasses are more attractive and you can look your best in all lighting conditions.
Anti-reflective glasses have sharper vision with less glare when driving at night and greater comfort during prolonged computer use. So, you can find that anti-reflective glasses come with many benefits.

Optical glasses are mainly suitable for the use of photometric glasses. Both the lens material and the production process have higher requirements. A panchromatic or half chromatic resin lens is added to an optical lens, and then they can be sunglasses and can try luminosity, made of myopic sunglasses.
What Are Varifocal Glasses?
Varifocal glasses, also known as varifocals, varifocal lenses, or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between.

Study On the Night Driving Glasses
Researchers at Harvard's Schepens Eye Research Institute recently conducted a study to find out if wearing night driving glasses while driving at night is good for vision. All 22 participants drove under four conditions that simulated night driving, wearing either yellow night driving glasses or glasses with clear lenses. Each participant drove with or without the headlight glare simulator activated to simulate the effect of oncoming traffic. The study found that wearing glasses while driving at night didn't seem to improve: how well the participants were able to recognize pedestrians at night and negative effects of headlight glare on pedestrian detection. Our data suggest that wearing yellow lenses while driving at night does not improve performance at the most critical task: pedestrian detection, the study's authors said. A small 2019 study showed that night driving glasses can actually slow down visual reflection by a fraction of a second, making night vision worse.
