Result: The number of global patents in treating and preventing asthenopia gradually increased,and the proportion of patents from China was more than 99%.The main patent applications were pharmaceutical composition,oral preparation,external eye patch and so on,but the ratio of licensed patents in total patents was low.In term of drug utilizing regularity,the oral prescriptions paid much attention to using TCM for nourishing the liver and kidney,while external prescriptions highlighted relieving sickness heat and detoxification.
