眼镜,通常用于矫正屈光,很少考虑用它来防止有害光对眼的损伤。随着工业的发展,人们利用各种光线来为人类服务,如用紫外线消毒、红外线取暖,激光打孔、X光透视、微波通讯、Y射线作放射治疗等等,但这些光线也给人们带来危害,它们在足够数量时会损坏细胞组织,对人眼也带来危害。就以紫外线来说,其短波紫外线会造成电光性眼炎,而长波紫外线则造成水晶体混浊和白内障等眼病。为了保护眼睛,人们研制成各种防护眼镜,如电焊镜、X光防护镜、微波镜、各类激光防护镜。这些镜大多 Glasses, usually used to correct refractive errors, rarely consider using it to prevent harmful effects of harmful light on the eye. With the development of industry, people use various kinds of light to serve human beings, such as ultraviolet disinfection, infrared heating, laser drilling, X-ray, microwave communication, Y-ray for radiation therapy, etc., To harm, they will damage the cell tissue in a sufficient number of human eyes are also harmful. To ultraviolet light, the shortwave ultraviolet light can cause electro-optic ophthalmia, while the long-wave ultraviolet light is caused by crystal opacity and cataract and other eye diseases. In order to protect the eyes, people developed a variety of protective glasses, such as electric welding, X-ray protective glasses, microwave mirrors, various types of laser protective glasses. Most of these mirrors
