A correct frame width will ensure your eyes are properly aligned in the center of your lenses for optimal vision. The frame width should be slightly wider than your face but with the space between your temple and frame no larger than a finger’s width.

Moreover, you also should ensure the Arm Length is right for you. The arms of glasses should run along with your temple and wraps around your ears. The arms should run horizontally and sit comfortably around your ears only touching your head right before your ears. Of course, you can find the arms-length of glasses on the side of the temple.

The frame of prescription glasses

At present, the more common materials for frames are non-metal and metal. Non-metals mainly include TR90, sheet material, etc., and metals include alloys, titanium, and so on. TR90 and sheet material are actually plastics, but they are firm and are not easy be deformed at room temperature. Also, they have good formability so that they can be made in many fashionable styles. The general alloy material has good firmness and flexibility, but the disadvantage is that it is easy to fade. The pure titanium frame is corrosion-resistant and very strong. It is about 40% lighter than the general alloy frame. It must be welded and electroplated in an oxygen-free state, which requires high equipment and technology. Relatively speaking, the price of TR90 and alloys will be lower, and pure titanium will be more expensive. You can choose according to your budget.
