While many of us look at the front of the frames and the lenses when picking out a pair of eyewear, you should also consider the temples. Also known as eyeglasses arms, this part of the glasses keep the frame front secure as well the part connected to the ears.
Metal temples are usually more robust to breaking and bending compared to plastic. There are though many plastic related materials such as nylon and polycarbonate, which are strong as well. These typically are used for sports glasses/goggles.
There are also spring-hinged temples such as the Optx 20/20 FlexReaders 4 that allow for a wider opening of the temple without it breaking. Without spring hinges glasses too tight on the wearer’s head could leave marks on the side of the face.
Metal frames also many times feature temple tips or end pieces. These parts of the temple allow for adjusting the temple length and how tight it will be on your face. In contrast, plastic temples don’t have tips, as the one piece is non-removable. Usually temple tips are made of plastic, rubber or silicone in a variety of shapes for comfort.
If you are a person who experiences skin allergies, metal, especially nickel metal may not be the right direction to go in. It could redden and irritate the skin. People with this allergy that are still set on metal frames should look into frames and temples made of titanium.
As you can see there are a lot of variables in choosing the best pair of eyewear for you and your family. Test a few and see what feels best.
