Adjustment
The adjustment of a frame makes a big difference in terms of comfort and vision. A frame that keeps its fit longer is a guarantee of quality. Be aware that all eyeglass frames require readjustments at least a few times a year, but as a general rule, if your frame loses its proper fit in a few days, it may indicate poor quality.
Flexibility
Generally speaking, whether it’s made of metal or plastic, a better frame will either be more flexible and durable or, depending on its material, will have a better shape memory. This flexibility reduces the risk of breakage and increases comfort. Don’t hesitate to ask a professional to handle the frame you are interested in to verify its flexibility. It’s amazing how malleable plastic or metal can be!
Look & Feel
Quality plastic frames usually have a variety of features. They have a rich colour, they are soft to the touch, glossy and all their edges are polished. Quality plastic frames usually have a certain weight in hand and are not among the lightest. However, this is different for metal frames, for example, which can be made of ultra-light materials such as titanium and stainless steel.
