Radiation protection glasses are made by adding some compound substances during the processing of the lens of the glasses, and the relevant radiation protection film is pasted on the lenses. Because computer radiation is caused by electromagnetic waves, generally speaking, electromagnetic waves have a certain amplitude and wavelength. The compound medium and the radiation protection film of the radiation protection glasses use this principle to use electromagnetic waves of different wavelengths to interfere with each other to achieve the purpose of radiation protection. Before buying sunglasses, we must first recognize these two points. One is that not all sunglasses have UV protection. When the eye encounters strong light, the pupil will naturally become smaller, so that the ultraviolet energy entering the eye is reduced. Once wearing glasses without UV protection, the pupils will be dilated, and the glasses do not have the effect of isolating ultraviolet rays. Eyes are like a wide open door, and letting ultraviolet rays enter, the damage to the eyes can be imagined. The second is that sunglasses can block ultraviolet rays because a special coating is added to the lenses. Inferior sunglasses not only cannot block ultraviolet rays, but also severely reduce the transmittance of the lenses, making the pupils larger, and the ultraviolet rays will be injected in large quantities. Damage to the eyes. In addition, inferior lenses also cause people to have symptoms of visual fatigue such as nausea, forgetfulness, and insomnia.
