From a Traditional Chinese Medicine (TCM) perspective, the eyes are not viewed as isolated organs, but as closely connected to the body’s internal systems—particularly blood circulation, body fluids, and overall vitality.

When blood and fluid nourishment to the eyes is insufficient or circulation becomes sluggish, visual discomfort may gradually appear. This can present as dryness, visual fatigue, sensitivity to light, or disturbances such as floating spots. In modern terms, these experiences are often described as dry eye, glare sensitivity, floaters, or changes in visual clarity commonly associated with nearsightedness, farsightedness, or astigmatism.

In some cases, eye discomfort may also involve redness, irritation, or pressure sensations. Conditions that are clinically described as conjunctival irritation (red eye) or patterns associated with glaucoma-related pressure sensitivity are, from a TCM viewpoint, reflections of underlying imbalance rather than isolated eye problems.

Long-term strain on the nervous system may further influence eye function. When circulation and nourishment to the optic pathway are compromised, symptoms described in medical contexts as optic nerve inflammation, optic nerve degeneration, or visual weakness may become more noticeable. TCM interprets these patterns through the lens of internal depletion and reduced regulatory capacity, rather than a single localized cause.

Modern lifestyle factors often accelerate these imbalances. Prolonged screen use, inadequate rest, limited exposure to natural light, irregular sleep patterns, emotional stress, and dietary habits that weaken digestive and circulatory function all place additional demand on the eyes. Over time, the eyes may struggle to recover, and discomfort becomes more persistent.

From this holistic perspective, eye-related discomfort develops through the combined effects of circulation imbalance, fluid depletion, nervous system strain, and lifestyle stress, rather than from the eyes alone.
