Titanium has been an increasingly used material in the optical industry since the 1980s. Titanium glasses first appeared in France around 1986, while they were already very common in Japan.
Origin and manufacture of titanium:
Discovered in 1791 by the British William Gregor, the first use of titanium dates back to the beginning of the 20th century, as an additive to cast iron and steel, in the form of ferrotitanium. It is the 22nd element of the periodic classification, with the symbol Ti. It is a stable element belonging to the family of transition metals such as silver, cadmium... It is the 7th element in order of abundance in the Earth's crust and most igneous or sedentary rocks contain it. However, it is mainly imported from Australia.
The manufacture of titanium requires various complex operations that we will not elaborate on... we will simply say that it is obtained in the form of a sponge whose excess magnesium chloride is distilled under vacuum at about 1000°C. This sponge is then consolidated by vacuum melting to obtain ingots or castings. These processes explain the cost of this material, which is also why it is used with other materials in the form of alloys such as beta-titanium.
Characteristics of titanium glasses, what are their advantages?
Titanium glasses are an excellent choice for wearers.
Titanium prescription glasses are extremely lightweight, on average 40 to 50% lighter than traditional metal frames.
It is scientifically recognized for its hypoallergenic properties.
In addition, titanium is a perfectly anti-corrosive material; it resists perspiration and seawater. It is the ideal material for people with acidic sweat. Perspiration and corrosive atmospheres are the lot of many people; titanium frames respond well to the demands of certain professions or the practice of a sport.
This material is more elastic than other commonly used materials, providing superior fit and comfort for titanium prescription glasses. The frames deform little at the front, and the temples remain flexible.
That's why they are perfect for presbyopia magnifying glasses that are constantly taken off and put back on.
While their price remains a little higher, the advantages of titanium are undeniable. The solidity of the material combined with a timeless design makes titanium glasses a high-quality and timeless product.
