What are the benefits of memory metal frames?
Memory metal materials are inherently lighter than metal materials, which can reduce the pressure on the bridge of the nose and skin. The memory metal frame is super elastic, so it never deforms, and it is so apparent that the temples on both sides of the frame line up with the ring. Because the bending can be automatically restored to its original state, the stability is comparatively strong. It has the benefits of high-temperature resistance, corrosion resistance, which will not cause skin allergy, and so on. It is a hypoallergenic lightweight metal for eyeglass frames that is strong and flexible. It is resistant to corrosion, making it proper for people who work, live or play sports in all kinds of outdoor weather conditions. The memory metal can be placed on the side of the face, making it easier and more comfortable to wear. The memory temples can freely rebound 180 degrees without deformation, making up for the insufficient effect of elastic β titanium. This kind of frame is not able to recover due to careless bending, and it has the function of restoring shape itself.
Different Type of Lenses: How to Choose
In this section, we will list some of the lenses for glasses.
Plastic lenses: In 1947, the Armorlite Lens Company in California introduced the first lightweight plastic lenses. The lenses were made of a plastic polymer called CR-39, because it was the 39th formulation of a thermal-cured plastic developed by PPG Industries in the early 1940s. Plastic lenses are light and low cost.
Polycarbonate lenses: polycarbonate lenses were first introduced in the 1970s and they have become increasingly popular anad remained for a long time. Polycarbonate glasses are slighter and significantly more impact-resistant than CR-39 plastic, making them a preferred material for children’s eyewear, safety glasses, and sports eyewear.
The extraction of titanium
Nowadays, the commonly used extraction method is the reduction method of titanium tetrachloride. Compared to copper and zinc, although high in content, much more expensive. On the other hand, China is the country with the largest reserves of titanium, and a large number of steel mills with perennial overcapacity began to produce titanium, so the price of titanium fell year after year.
