Hao Qian explained what are the advantages and precautions of PC lenses?

1. What is a PC lens: PC tablets are also known as "space tablets" and "world tablets". The chemical name is polycarbonate, which is a thermoplastic material (that is, the material is solid, and the lens is also solid after being heated). Strong and tough, not broken (2cm can be used for bulletproof glass), so it is also called safety lens. The specific gravity is only 2 grams per cubic centimeter, which is the lightest material currently used for lenses. If there is no problem in the process, the weight is 37% lighter than the general resin sheet, and the impact resistance is 12 times higher than the general resin! Good anti-ultraviolet function, not easy to yellow.

2. Characteristics: The material has good light transmittance and is not easily deformed. Generally, the temperature will be deformed when it reaches more than 120. This high temperature resistance has many advantages. In addition, PC has high impact strength, high hardness, good thermoplasticity, good electrical insulation, and will not pollute the environment. The PC lens inherits the characteristics of the original material's super impact resistance, and because of the high refractive index and light specific gravity, the weight of the lens is greatly reduced, and it will not yellow within the general 3-5 years. If there is no problem in the process, the weight is 37% lighter than the general resin sheet, and the impact resistance is 12 times higher than the general resin!

Third, maintenance: The advantages and precautions of PC lenses are very important. Incorrect maintenance will only add a variety of other damages. The cloth for scrubbing the lens must be soft, otherwise the lens may be scratched. The cotton lens cloth should be used for scrubbing, but it is not possible to scrub the lens often, because the PC is neutral, and often scrubbing will generate static electricity, and will also absorb the oil fumes in the air, which will damage the lens. When cleaning, you need to use alcohol or neutral detergent to wipe the test, then rinse with water, and finally use a cotton mirror cloth or a soft paper towel to absorb the water.
