How to choose anti-radiation anti-fatigue goggles?

Anti-radiation anti-fatigue high-end goggles, mainly used to protect the eyes from excessive ultraviolet rays and radiation rays such as computer and mobile phone screens. Our eyes are a very fragile organ and are particularly sensitive to these radiation rays. Except for some Except for special types of work with a large amount of radiation, the most suitable people are office workers who deal with computers for a long time. When purchasing, we can choose really high-quality high-end products that can not only have high radiation, but also can resist fatigue. Health is very important. Of course, its beauty and practicality must also be considered. Let me talk about some purchasing skills from these aspects.

First of all, the choice of lens type: There are two types of lenses for radiation-proof glasses, one is coated lenses and the other is synthetic lenses. The surface coating lens is to coat a layer of reflective film on the surface of the lens, which can reflect and offset the radiation light; its advantage is that the process is simple and the cost is low, and the disadvantage is that the radiation protection performance is relatively low, and it can only prevent 30-50%. Durable, the surface coating layer is easy to wipe off, the market retail price of this kind of anti-radiation glasses is generally 100-200 yuan. Synthetic lenses are multi-layer vacuum synthesis of electromagnetic and reflective lens layers. Its advantages are durability, good light transmission, strong impact resistance, and a radiation protection rate of up to 99.9%, but its disadvantages are complicated process and high cost. The market retail price is generally higher than 300 yuan, or even thousands of yuan. The following is a comparison of the effects of vacuum synthetic lenses before and after use:

Secondly, it is the choice of lens quality: this should take into account the light transmittance of the lens, the thickness of the lens, the weight of the lens and the hardness of the lens. Compared with the aspheric ultra-thin optical lens, the light transmittance is better, and the glass lens is heavier than the resin lens. Glass lenses are harder and more wear-resistant than resin lenses. Resin lenses are stronger than glass lenses, impact-resistant and not fragile, and which one to choose depends on the needs of each person.
