The onset of glaucoma is closely related to local eye structure, age, gender, genetics, refractive errors, and other factors. Individuals possessing these characteristics constitute the high-risk group for glaucoma, susceptible to acute attacks triggered by adverse external stimuli—such as sleep deprivation potentially inducing glaucoma.Patients present with red eyes, pain, sudden vision loss, and may even experience nausea, vomiting, and general malaise. The condition can affect one or both eyes simultaneously. During an attack, intraocular pressure often surges above 50 mmHg (normal range: 10–21 mmHg), and the eyeball feels rock-hard to the touch.
Patients often report staying up late or experiencing fatigue before the attack, with some even attributing it to prolonged television viewing. Why do these factors trigger glaucoma attacks?
It turns out that excessive fatigue, sleep deprivation, emotional fluctuations, irregular eating habits, or overeating can disrupt the vascular-neural regulatory center, leading to vascular dysfunction:On one hand, they can dilate capillaries and increase vascular permeability, causing ciliary muscle edema and anterior displacement that obstructs the anterior chamber angle, blocking aqueous humor outflow. On the other hand, they can stimulate excessive aqueous humor production, elevating posterior chamber pressure. This pressure forces the peripheral iris forward, shallowing the anterior chamber and narrowing the angle. These factors collectively trigger a rapid rise in intraocular pressure, ultimately precipitating an acute glaucoma attack.
Therefore, physicians refer to these as triggers for acute glaucoma attacks. This underscores the critical importance for glaucoma patients to maintain regular routines, emotional stability, and balanced diets while actively avoiding adverse stimuli.
How to Prevent Glaucoma?
Prevention primarily targets individuals with risk factors.Individuals with glaucoma risk factors may develop the condition at any time when exposed to triggers like adverse psychological stress. Therefore, it is essential to eliminate all harmful factors that could elevate intraocular pressure in daily life to prevent glaucoma onset.
1. Maintain emotional well-being and avoid excessive mood swings. The primary trigger for glaucoma is prolonged negative psychological stress, including irritability, depression, anxiety, and fear.
2. Maintain a regular lifestyle and diet. Balance work and rest, engage in moderate exercise, avoid strenuous activities, ensure quality sleep, and consume a light yet nutritious diet. Abstain from smoking, alcohol, strong tea, and coffee. Control daily water intake to 1000–1200ml, with no single intake exceeding 400ml.
3. Practice eye hygiene and protection: Avoid reading in bright light, limit prolonged stays in dimly lit rooms, ensure adequate soft lighting, and prevent eye strain.
5. Individuals with glaucoma family history or risk factors must undergo regular follow-up examinations. Should any signs of onset appear, actively cooperate with treatment to prevent sudden loss of visual function.
We hope the above methods for triggering and preventing glaucoma provide some helpful guidance.

Dietary Approaches for Glaucoma: Four Therapeutic Methods for Patients
Glaucoma is a bilateral condition that may affect both eyes simultaneously or begin in one eye before progressing to bilateral blindness.
Beware of Developing Glaucoma from Sleeping with Your Head on the Desk
On hot, stuffy days after a heavy meal, midday drowsiness is common. Many take advantage of their lunch break to nap with their head resting on the desk. Little do they know that improper napping posture not only strains limbs but may also lead to glaucoma.
Glaucoma patients should avoid watching TV in the dark
To save electricity, many turn off the lights while watching TV. However, for glaucoma patients, dark environments can elevate intraocular pressure, increasing strain on the eyes.
