Abstract: Anti-radiation glasses can be used to reduce the damage to human eyes caused by electromagnetic radiation, which is of great significance for the quality of life and health and safety of glasses wearers. There are two types of anti-radiation eyeglasses: anti-radiation eyeglasses with coating and anti-radiation eyeglasses without coating. In this paper, a simulation model was developed by using CST-Microwave Studio to study the variation in microwave transmittance of glass lenses with the degree, over a degree range of 150-600 ° and a frequency range of 100-3000 MHz. It was found that the transmittance was increased with increasing electromagnetic wave frequency and degree of the lens, with a certain degree of fluctuation. In the lower frequency range, the transmittance of the glass lenses had only a slight increase with the degree, due to the influence of the fluctuation. In the higher frequency range, the increase in the transmittance became obvious and the increase followed a step-like pattern, also due to the fluctuation.
Key words: glass lenses; electromagnetic wave; transmittance properties
