Frames & Glasses 101

If you’ve recently been told that you need a prescription to correct your vision by a Miami Beach eye doctor, then you may be curious about picking out a pair of glasses. There are many different materials that glasses are made of, and there are several frame materials to choose from as well. The look of the glasses you choose is up to you, but there are some things you should know about the different materials you can choose from. Some of them are better for certain situations, which is important to keep in mind if you want your glasses to last as long as possible. Eye doctors in Miami can speak with you about the different frame/lense materials and which ones are better for various environments.

What are the Different Materials of Glasses Available?

When it comes to picking out the right frame material, you need to know about the choices available to you. Primarily, there are plastic and metal frames. However, there are different plastics and metals that you can choose from.


● Cellulose acetate & zylonite – This material is popular because many colors and textures are available. They are also hypoallergenic, though they are not very strong or flexible.

● Cellulose propionate – This material is flexible and very hypoallergenic. They are also lightweight.

● Nylon – Nylon glasses are a common choice because they lightweight, strong, flexible, and hypoallergenic. However, they can only be coated so the designs may fade over time.


Titanium – Titanium glasses are strong, though not so flexible. They can also be corrosion resistant with the right coating, which makes them great for hazardous work environments.

● Beryllium – These glasses are one of the most common choices among metal frames because they are strong, flexible, lightweight, and corrosion resistant.

● Flexon – Out of all metal frames, flexon ones are the most flexible. They are also fairly strong and hypoallergenic. Not many styles are available, though.

● Aluminum – Aluminum frames are the least popular out of all the metals because they are not flexible or hypoallergenic, but they do come in various styles because they are able to be coated.

The Actual Glass

The actual lense of your glasses also comes in many different materials. There are standard plastic, mid-index plastic, high-index plastic, polycarbonate, and High Definition glasses. Polycarbonate lenses are shatter proof, which is why many parents choose this material for their children. High-index plastic lenses are better for stronger prescriptions, but they are typically more expensive than the other plastic lenses. You can speak with your optometrist in Miami Beach about which lense is going to be best for you as well. A professional eye doctor in Miami Beach will have no problem helping you pick out the best frames and lenses to fit your lifestyle.
