Abstract

The invention provides artificial tear collyrium for relieving asthenopia. Persons who operate video terminals and watch screens for a long time have the symptoms of dry eyes, asthenopia, blurred vision and the like, which causes myopia aggravation and fixation function decrease, eyesight regulating capacity decrease, xerophthalmia and the like. The symptom of dry eyes is caused by insufficient tear, so that artificial tear is developed for relieving collyrium, and the formula adopting a pH buffer system is stable in property and mild in application, and is added with vitamin A, taurine and chloramphenicol to achieve the effects of preventing nyctalopia, enhancing eye resistance, sterilizing and removing bacteria.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to an artificial tear eyewash for relieving eye fatigue. Background technique [0002] Along with popularizing of notebook computer, people have to face computer for a long time in life, office, and the harm that long-term use computer causes to eyes is also more and more obvious. The display principle of computer CRT cathode ray tube is the same as that of TV. The electron flow emitted by the cathode ray tube hits the fluorescent screen to display visible light. This process will produce harmful rays to the human body, and there is a low-frequency electromagnetic field, which is easy to suffer from electromagnetic pollution for a long time. It is easy to cause various eye diseases. Most people who use computers often have "video terminal syndrome", which is dry eyes, eye fatigue, blurred vision and other symptoms caused by staring at the fluorescent screen before operating vide...
