What causes a feeling of head distension and blurred vision?

Head heaviness and blurred vision may be caused by lack of sleep, elevated blood pressure, glaucoma, etc., and require targeted treatment. The specific analysis is as follows:

1. Sleep deprivation

Prolonged sleep deprivation can lead to abnormal blood vessels and circulation in the eyes and brain, slow lymphatic metabolism, and accumulation of excess fluid in the eye and brain areas, resulting in symptoms such as head fullness and blurred vision. It is recommended to improve sleep quality, avoid staying up late, and maintain a regular sleep schedule with early bedtime and early rising.

2. Elevated blood pressure

When blood pressure rises, cerebral blood vessels dilate and blood flow to the brain increases, leading to symptoms such as head fullness, dizziness, and blurred vision. Under medical guidance, medications such as felodipine sustained-release tablets or nifedipine sustained-release tablets may be used for treatment.

3. Glaucoma

Glaucoma may be caused by aging factors. During an episode of glaucoma, increased intraocular pressure causes expansion of the eyeball wall, stimulating sensory nerves within the wall and leading to these symptoms. Under medical supervision, treatments such as brimonidine tartrate ophthalmic solution or carteolol hydrochloride ophthalmic solution may be used.

In addition to the above, conditions such as diabetes, hyperthyroidism, heart disease, and others can also cause head heaviness and blurred vision. It is recommended to seek timely medical care at a hospital to prevent adverse effects on health.
