Aching, Stiff Eyes? Why You Should Suspect 'This' Instead of Simple Fatigue

When translating the Donguibogam concept of liver heat into the language of modern medicine, it is closely linked to autonomic nervous system imbalance. Chronic stress, a common malady of modern life, excessively activates the sympathetic nerve, placing our bodies under continuous tension much like an engine constantly running at high RPM. This persistent tension significantly affects the delicate tissues around the eyes. A stiff ache deep inside the eyes or the sensation of the eyeballs popping out can arise from multiple complex factors. First is ocular muscle hypertension caused by excessive visual focus. Prolonged use of computers or smartphones keeps the ciliary muscle in constant contraction, causing stiffness similar to delayed onset muscle soreness. In particular, extreme fatigue in the extraocular muscles and ciliary muscle irritates the surrounding nerves, easily leading to orbital pain. Second is blood circulation disorder and inflammation. Stress and tension constrict microvessels, impeding the supply of oxygen and nutrients to tissues around the eyes while obstructing waste removal. Such an environment can induce a chronic inflammatory response, where inflammatory mediators stimulate nerves to provoke deep, stabbing pain. It resembles waste backing up in a clogged drain. Third, trigeminal nerve hypersensitivity is another critical factor. The trigeminal nerve, responsible for facial sensation, also branches around the eyes; chronic stress or tension can sensitize this nerve, causing substantial pain even from minor stimuli. The feeling that the eyeballs might pop out is a typical feature of neuropathic pain, which can occur via nerve hypersensitivity even without elevated intraocular pressure. Fourth, dry eye syndrome is a major factor exacerbating this discomfort. Autonomic nervous system imbalance decreases tear secretion and lowers tear film quality, drying the ocular surface. Dry eyes readily develop inflammation and pain even with minimal irritation, sharply escalating eye fatigue. It is like a weakening of the protective barrier that shields the eyeball from external insults. In conclusion, the pain feeling as if the eyeballs might pop out—attributed to liver heat in ancient times—is more than an isolated eye issue. It can be interpreted as a condition where stress and tension disrupt the autonomic nervous system, which in turn comprehensively triggers ocular muscle hypertension, blood circulation disorder, nerve hypersensitivity, and dry eye syndrome. Through this discomfort, your body is signaling you to pause and rest.
