A high-quality discount prescription glasses frame is made with good materials, good design, good craftsmanship, and good accessories. This is also the reason for producing frames, which can ensure quality and align with standard product quality.

High cost-effectiveness is not only about low prices but also about the lack of comparative value for different qualities. It is easy to compare prices, and if an independent brand only focuses on low prices as a selling point, many of them are simply trading in the concept of low prices and high cost-effectiveness.

The materials with better metal properties are pure titanium and beta-titanium, followed by alloys. Plastic materials are best made of general board and tungsten titanium, followed by TR90. Good materials are usually indicated on the discount prescription glasses' frame lining or legs.

A good quality eyeglass frame liner logo should be neat and the font should be clear. The details of the metal hinge are very important. If the hinge is rough, don't mention how good the frame material is.

For mirror leg identification, pay attention to the information on both sides of the mirror legs. High-quality frames will have logos, materials, models, sizes, and other information printed on both legs.

If laser engraving is used to engrave text on metal frames, the quality will also be particularly good. Some frames have legs that are too thin to engrave. Why is pure titanium or beta titanium generally recommended for metals, while sheet metal and tungsten titanium are recommended for plastics?

Many ordinary metals are easily oxidized to form copper green; some may even cause skin allergies and other problems. Pure titanium is much better, not only light but also corrosion-resistant, not easily allergic, and not easy to fade, which does not mean that it will not fade.
