There are basically two types of frame material, metal and plastic. Current advances in the type of materials used makes either a good choice for most individuals. Back to Top Metal Frames Metal frames have a longer life but tend to need more maintenance than plastic ones. Most metal frames have nose pads that are connected to the frame. Nose pads work well for people who have a small bridge or a small nose.
Some people can be allergic to certain metals.
If you have sensitive skin please look for metal frames that are hypo-allergenic. Back to Top Plastic Frames Plastic Frames are typically lighter than metal. Some types of plastic contract and expand with temperature changes and need to be adjusted more often. Most plastic frames do not have separate nose pads attached to the frame. Certain types of plastic frames can become brittle over time and may not be the best choice if you want to keep your frames and just get new lenses time after time.
