The most durable eyeglass frames Your choices boil down to plastic or metal. Some frames combine metal and plastic, but that’s more of a fashion convention than a durability boost. Isn’t metal inherently tougher than plastic? Perhaps, but everything depends on how you use your eyeglasses. ...
If the right lens is higher than the left lens, bend the left temple arm down. Top tip: We only recommend doing this with wire metal frames. Plastic frames with thick temple arms may need to be heated to adjust; we do not recommend trying this at home. You should seek the assistance...
If your frame has broken into two separate pieces, the best option is to have it repaired by a professional. Broken metal frames can’t be glued together and attempting to weld or solder it yourself will likely damage the lenses. It’s possible to try and mendplastic framesbut the risk i...
5 The finished lenses are now ready to be mounted in eyeglass frames. Frames are constructed to hold the lenses in place using either a tension mount or screw mount design. Tension mounting is typically used in plastic frames. In this type of frame, the dimensions of the lens opening on ...
If you sit on a pair of aluminum eyeglass frames and bend them permanently (in scientific words, "subject them to a plastic deformation"), it's tricky to get them back exactly how they were. You have to use your own memory of what the frames were originally like and laboriously twist ...
changes, they don't transmit all light wavelengths as well as glass, and they don't always bend light as successfully (glass typically has a higher refractive index, although it is possible to use special, high refractive index plastic as an alternative if you want thin, light, eyeglass ...
Be careful using the hair dryer as you could melt the plastic. Another way to bend plastic frames is to run them under hot water for 15 to 25 seconds before trying to make adjustments. The arm should become pliable enough to adjust, but be careful. The plastic can snap even when heated...

Typically that means they have to be made from materials such as stainless steel or tough alloys such as bronze. Some alloys have a property called shape-memory, which means they're naturally springy. Eyeglass frames are often made from a nickel- titanium shape-memory alloy called nitinol, ...
