Lower eyelid fluttering can be caused by visual fatigue, eye neuropathy, inflammation and infection. 1. Visual fatigue: If you use your eyes for a long period of time in close proximity, such as looking at the computer, cell phone, etc., it will easily lead to overexertion of the eyes and visual fatigue, which will cause the eye muscles to be tired, resulting in the lower eyelid throbbing of the eyes. 2. Ocular neuropathy: when the optic nerve of the eye is damaged or compressed, it will easily affect the innervation ability of the eye muscles, stimulate the eye muscles, cause muscle twitching, and the phenomenon of lower eyelid throbbing occurs. 3. Inflammatory infections: If you often rub your eyes with your hands or don’t pay attention to the cleaning of the eye area, it may lead to conjunctivitis, keratitis and other diseases, causing inflammatory infections and the appearance of the lower eyelid throbbing. If you have a throbbing lower eyelid, you should go to the ophthalmology department of the hospital in a timely manner to clarify the cause of the problem and follow the doctor’s instructions for treatment.
