The spirit behind celluloid glasses

Because celluloid material is flammable, it cannot be mechanized and basically needs to be created by hand, which forms a unique set of handcraft modes of Japanese crafters. Today, there are only a few celluloid factories in Japan, and the unique manual process and production are relatively small. This makes celluloid handmade glasses even rarer and more valuable. Celluloid was originally a very common and cheap material, even with a certain degree of danger, but because of the unique craftsmanship of skilled craftsmen, its performance was brought to the extreme, so that celluloid glasses became unique and sought after by some people. The material of the frame is an important factor that determines the comfort of the glasses. While ensuring comfort, people hope that the glasses can have a decorative effect and play a role in clothing matching in different scenes.



How to adapt to progressive lenses?

People who are prone to motion sickness or have inner ear diseases may suffer dizziness, nausea, vomiting, and other symptoms due to their inability to tolerate the slight deformation of the visual objects, so they need to pay more attention when wearing them. For people who have not worn reading glasses before, it is not recommended to wear graded multi-focus glasses directly because their eyes will not be able to adapt quickly.


Are blue lenses good for driving?

Do not buy blue sunglasses, which cannot filter ultraviolet rays. In the choice of sunglasses, try to choose brown or gray. When driving a car, choose to wear sunglasses, and safety should come first. Wearing and viewing comfort is the most important indicator. It is worth reminding that wearing dark-colored sunglasses will create a very dark environment for the eyes, which will easily lead to pupil dilation, and long-term wearing will cause certain damage to the eyes.



When were the first glasses invented?

No one knows when the first pair of glasses were invented, but we do know that the grinding techniques for making simple magnifying glasses have been around since 1000 AD, especially in regions where glasses were already produced (including northern Italy). The earliest artwork of glasses appears in the Treviso Cathedral fresco painted by Tommaso de Modena in 1352. There is reliable evidence that eyeglasses were invented in Italy in the late 13th century. The first pair we think of as eyeglasses appeared in Italian pizza in the late 12th century and looked more like two small magnifying glasses (made of raised glass) riveted together at the top of the handle. In 1266, The English Franciscan Monk Roger Bacon wrote about the scientific principles of corrective lenses, but there is no evidence that he applied this knowledge to the manufacture of eyeglasses.

Anti-reflection Coating

Anti-reflection Coating, known as reflective coating and antireflection film, is called anti-reflection coating in English, or AR Coating for short. Initially, anti-reflection coating technology was used in the sights of weapons. It was only after the war that the technique was used to improve the performance of eyeglasses. Another problem occurs when taking pictures because the lens's surface is relatively reflective. The resulting photos don't show the eyes of friends who wear glasses. This problem is solved by plating anti-reflection film.
