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.

Benjamin Franklin, an American scientist, and philosopher invented bifocals, which divide the lenses into far and near parts. The two lenses are held together by a metal frame. Frame construction has improved over the centuries, and today frames have come in different kinds of styles and designs. Unbreakable lenses were invented in 1955, and in 1971 a new type of lens combining plastic and glass properties was invented.

What Is Trivex Lens?

Trivex is another light, impact-resistant eyeglasses lenses. Like polycarbonate lens, Trivex is an excellent lens material for safety applications and children’s eyewear.

Trivex lenses are made of a urethane-based monomer. They are produced using a slower, cast molding process similar to how regular plastic lenses are made.
