Prepare a few pairs of glasses
Many people now have a 'reserve' of glasses. For example, you can choose two pairs of glasses. One pair is for daily use, and the style should be relatively simple and traditional. The other pair is for use at gatherings or weekends and can be as cool as you want. The more conservative style is a thin and bright metal frame that matches the shape of your face. For the other pair, you can choose a flat plastic frame or a shiny polished metal frame with a unique shape.
Difference between green film and blue film
In addition to the usual hardening, anti-fouling, anti-reflection, anti-radiation, and other functions, the green film has remarkable anti-ultraviolet performance, suitable for people who work outdoors for a long time to use. In addition to the general hardening, anti-fouling, anti-reflection, and anti-ultraviolet functions, blue film’s anti-radiation ability is very good, and it is suitable for computer workers and other people affected by radiation greater.
The coated lenses were originally produced in green, mainly to distinguish them from the uncoated lenses. At 515 nm, the reflection increases the reflectivity by about 2%, so there is a contrast, and the green film is seen in the reflection. This film is the most standard anti-reflective film, and it is the best and oldest one available.
What can I do if the rimless glasses frame is broken?
It depends on the material of the frames. If it is a metal frame, the welding effect of 50 yuan is not worth looking forward to, because the high temperature will burn the welding point and the surrounding color. The electroplating will be destroyed, and it is difficult to accept the appearance. If the metal material is alloyed copper, it will quickly corrode and produce patina. If your frame is broken in a temple, you can fix it yourself with 502 glue or duct tape, but the look will definitely be affected. Or you can go to the optician shop to change the temple. But if all the temples are broken, it's impossible to repair.

When the titanium purity reached more than 99% of the titanium metal materials, they can be called pure titanium glasses. Many people may not know what pure titanium is. In reality, many famous brand glasses are made of this material. The frames made of pure titanium have the benefits of high melting point, light material, strong resistance to corrosion, and strong electroplating, to ensure the two important properties of beauty and durability spectacle frames.
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.
How do you clean an eyeglass case?
Sprinkle a little water on the glasses case first, to soften the dirt and dust on it. Brush gently with a soft brush to avoid damaging the glasses case. The inside of the case needs to be cleaned with a brush. Use a rag to wipe the surface of the glasses case for moisture and dirt. Wash it several times with a wet cloth. Use paper towels to dry the surface and interior. And then dry in the sun.
