Cellulose Acetate
Acetate is a kind of thermoplastic resin obtained by esterifying acetic acid to acetic anhydride under the action of a catalyst. Acetate is resistant to water, gasoline, mineral oil, and lipids, weak alkaline solutions, and acids, excellent weather resistance, not resistant to ethanol, strong acids, and strong alkaline solutions. During thermoforming, it is very necessary to dry the material before forming. Acetate was born in the early 20th century, and was successfully trial-produced and industrialized by the UK in the early 1920s. At present, it is the second-largest variety in cellulose fiber after viscose fiber. Acetate can be used to make textiles, cigarette filters, film bases, and plastic products.
Eye problems that may occur while driving.
Visual fatigue and xerophthalmia: when driving, the spirit and eyes are in a highly tense state, reducing the blink of an eye, which will easily cause eye fatigue and xerophthalmia. Flash glare -- car headlights and city light pollution -- can cause serious damage to the eyes. UV damage: UV radiation is strong when driving in the daytime, especially in the plateau and snow weather. Nocturnal myopia: nocturnal light is insufficient, so it can make the eye pupil dilate, causing nocturnal vision to drop influence driving safety.
Does the phone screen have irregular color bars when wearing polarized lenses?
It is mainly the special properties of the polarizing film. The polarizer is able to see the internal stresses in the plastic, so when we usually look at the edge of the mobile phone screen, it will have a colored stripe or a black piece, which is mainly caused by the uneven edge pressure when the screen is installed. It's mostly a matter of light and shade. Wearing a polarized lens to see the LCD screen a tilt will find that the screen darkens, mainly because the polarizing lens can absorb light in a certain direction. The LCD screen is a one-way light (different from sunlight), so it is absorbed, so it is found to be dark.

Can you wear blue light glasses while driving?
The damage of blue light has a cumulative effect. The longer the exposure time is, the more serious the damage of retinal cells will be, which will eventually lead to irreversible damage of the structure and function of the retina. Once the retina has permanent damage, degeneration will directly affect the metabolism and function of photoreceptor cells, resulting in vision loss. It depends on the glasses you're wearing. The function of anti-blue light glasses depends on the material of the glasses. Some blue light glasses have a special anti-reflective coating, which can reduce glare. These glasses are definitely helpful when driving at night.
