Introduction
Eye discomfort with constant tearing may be due to physiological factors, such as eye irritation caused by smoke, dust, windblown sand, or foreign bodies like eyelashes or animal hair entering the eye. It could also result from pathological conditions, such as allergic conjunctivitis, in which inflammatory stimulation leads to the discharge of inflammatory exudate, or trichiasis, in which misdirected eyelashes irritate the eye. Additionally, dry eye syndrome—caused by insufficient tear production or excessive tear evaporation—may also be responsible.
Eye discomfort with constant tearing may be caused by physiological factors or pathological conditions such as allergic conjunctivitis, trichiasis, or dry eye syndrome.
I. Physiological Factors:
This may occur when the eyes are irritated by smoke, dust, shampoo, or other substances, or when foreign bodies such as eyelashes or animal hair enter the eye and are not promptly removed, causing ocular irritation.
II. Pathological Factors:
1. Allergic Conjunctivitis: Exposure to allergens such as pollen or dust mites, or use of substandard eye drops or cosmetics, may trigger allergic conjunctivitis. Inflammation and inflammatory exudates result in tearing.
2. Trichiasis: Scarring of the skin around the eyelashes due to conditions such as blepharitis, chalazion, or trachoma may cause scar tissue to pull the eyelashes inward (trichiasis), leading to eye irritation.
3. Dry Eye Syndrome: Poor dietary habits, such as picky eating leading to insufficient vitamin A intake, prolonged use of contact lenses, or extended screen time on computers, smartphones, and other electronic devices may result in inadequate tear production or excessive tear evaporation, causing dry eye syndrome.
In addition, glaucoma could also be a potential cause. It is recommended to seek timely medical evaluation to determine the underlying cause and receive appropriate treatment as directed by a physician.
