Lenses are divided into glass lens, resin lens, and PC lens, and you can choose according to your preferences. The glass lens has a stable refractive index, good abrasion resistance, and stable optical performance, but it is relatively heavy and easy to break. Resin lens with high light transmittance is light, safe, and not easy to break, but the surface is easy to wear. PC lens has a high refractive index, but the surface is easy to wear.


Types of Single Vision Lenses

Single vision lenses come in several different types including the 1.59 polycarbonate single vision, 1.57 mid-index single vision and polarized single vision.

1.59 polycarbonate single vision lenses are characterized by their durability and impact resistance. They often include an anti-scratch coating or anti-reflective coating. This lens is much lighter and thinner than a traditional plastic lens, and it blocks the sun’s harmful UV, offering maximum UV protection.

1.57 mid-index single vision lenses are thinner than regular plastic and moderately lighter and stronger. They come with an anti-scratch coating or anti-reflective coating. These lenses are an ideal option for people with relatively higher prescriptions. But they are thicker than the polycarbonate lenses.

Polarized single vision lenses are sunglasses that protect your eyes from light that bounces off smooth, highly reflective surfaces like asphalt, snow, and water. These lenses work by controlling certain light properties and limiting specific wavelengths. They boast a vertical filter that does not allow horizontal glare to pass through.



What Should You Do If Your Glasses Are Broken?

Adjust the frame by yourself. If your frame is tilted, place your glasses on a flat surface to determine which arm is higher than the other. If the right arm looks raised, you'll need to use pliers to bend the left arm down at the hinge. Or, if the left arm is raised, bend the right arm at the hinge. You can bend your metal-framed arms inward. You can turn the nose pad inward if the glasses slip under your nose. To make the frames more flexible, you can heat them with a hairdryer. If the metal frame has broken into pieces, you may need to take it to a professional. However, if your metal frames just bend, you may be able to repair them by yourself.


Why do blue light glasses turn yellow?

The glasses are used for a long time. Blue lenses are usually light yellow. If the yellow is too deep, the resin lenses will oxidize and become yellow due to the long-wearing time. The lenses need to be replaced in time. Yellowing of the lens is related to the excessive secretion of facial grease, which leads to yellowing of the lens. The most direct way is to replace the lens glass.



What Is Polycarbonate Lens?

Polycarbonate was invented in the 1970s for aerospace applications and is currently used for the helmet visors of astronauts and for space shuttle windshields.

Polycarbonate lenses were introduced in the early 1980s in response to a demand for lightweight, impact-resistance lenses. Since then, polycarbonate glasses have become standard for safety glasses, sports goggles, and children’s eyewear.

Polycarbonate glasses come with a lot of features such as thin and light and they provide 100% percent UV protection and are up to 10 times more impact-resistance than plastic pr glasses lenses.
