Introduction
Sharp, needle-like pain at the outer corner of the eye may be caused by physiological factors or pathological conditions such as dry eye syndrome or conjunctival concretions. Appropriate treatment should be based on specific circumstances. The detailed analysis is as follows: If one frequently uses mobile phones or computers in daily life, and engages in prolonged eye use, the eye muscles may remain tense for extended periods, leading to eye strain.

Pricking pain at the outer corner of the eye, similar to being pricked by a needle, may be caused by physiological factors or pathological conditions such as dry eye syndrome or conjunctival concretions. Appropriate treatment should be based on specific circumstances. The detailed analysis is as follows:

I. Physiological Factors

If one frequently uses mobile phones or computers in daily life and engages in prolonged eye use, the eye muscles may remain tense for extended periods, leading to visual fatigue. Without timely rest, muscle spasms in the eyes can cause a sharp, needle-like pain at the outer corner of the eye. It is recommended to take appropriate breaks after using the eyes for a period of time to relieve eye strain.

II. Pathological Factors

1. Dry Eye Syndrome

If the eye has suffered trauma or inflammatory infection, lacrimal gland function may decrease, resulting in insufficient tear secretion to lubricate the eyeball, causing symptoms such as dryness, soreness, and aching. In severe cases, corneal damage may occur, leading to the aforementioned pain. Patients are advised to use medications such as sodium hyaluronate eye drops or carbomer eye gel under medical guidance.

2. Conjunctival Concretions

In patients with chronic conjunctivitis, inflammatory factors may spread to the conjunctiva and surrounding soft tissues, causing local cell shedding and accumulation, which may form conjunctival concretions. If these concretions grow large enough, they may rub against surrounding tissues and cause such painful symptoms. It is recommended that patients seek hospital care where the concretions can be surgically removed.

Besides the above, this condition may also result from other diseases such as conjunctivitis, keratitis, or foreign bodies in the conjunctival sac. When significant eye discomfort occurs, patients should promptly seek medical attention for proper diagnosis and treatment.
