How to Choose the Ideal Lenses for Your Glasses

Updated: Feb 10, 2022

Prescription glasses and contact lenses are designed to correct different vision problems. It’s not just enough to choose a good-looking frame, you also need to pay attention to the lenses. Choosing the ideal lenses for your new eyeglasses can be a challenge with all of today’s lens and coating options.

How to Choose the Ideal Lenses for Your Glasses

Here are tips for choosing the right lenses for your glasses.

Plastic Lenses

Back in the day, eyeglasses were all made with glass. While it gives a clear view, this material is heavy and prone to breaking. In 1947, the Armorlite Lens Company in California invented the first lightweight plastic eyeglass lenses, which were made of CR-39 plastic polymer. These lenses are lighter, easy to tint, and cost-effective. However, they are not as impact-resistant, can be heavy, and thicker than other materials. In addition, they can’t be used in semi-rimless frames.

Polycarbonate Lenses

You want lenses and glasses that are strong and long-lasting. In the 1970s, polycarbonate lenses were originally made for safety glasses. They are known for their high impact and scratch resistance. Polycarbonate lenses are great because they work well against scratches and chips. They can also come with a 100 percent UV filter.


Trivex lenses are an even better option than polycarbonate lenses. They offer better resistance than plastic lenses and are more lightweight as well. Another great feature of these lenses is that they block 100 percent of harmful UV rays. They are made from a cast molding like glass lenses, giving users clearer vision.

High-Index Plastic Lenses

Manufacturers introduced high-index plastic lenses due to the demand for thinner, lighter lenses. They are lighter than CR-39 plastic lenses since they have a higher index of refraction and may also feature a lower specific gravity.
