Introduction
In general, eye redness may be caused by prolonged eye use, exposure to irritants, lack of sleep, keratitis, glaucoma, or other factors. After identifying the specific cause, appropriate measures such as general treatment, medication, or surgical treatment should be taken under the guidance of a professional physician. During treatment, the specific therapeutic approach should be selected according to the underlying cause.
Generally, eye congestion may be caused by prolonged eye use, contact with irritants, lack of sleep, keratitis, glaucoma, and other factors. After identifying the specific cause, improvements can be made under the guidance of a professional physician through general treatments, medication, and other measures. A detailed analysis is as follows:
1. Prolonged Eye Use
Staring at computer screens, mobile phones, or other electronic devices for extended periods can keep the eye muscles in constant tension, reduce blinking frequency, and lead to dryness, fatigue, and consequently eye congestion. It may also be accompanied by symptoms such as dry eyes, blurred vision, and headaches. It is recommended to rest the eyes timely to alleviate fatigue.
2. Contact with Irritants
Contact of the eyes with irritants such as smoke, dust, pollen, or residual cosmetics may stimulate ocular tissues, trigger inflammatory responses, and cause eye congestion. Symptoms may include eye pain, foreign body sensation, and tearing. It is recommended to immediately stop contact with the irritant, rinse the eyes thoroughly with clean water to help remove residual substances. If symptoms persist, seek medical attention promptly.
3. Lack of Sleep
Long-term sleep deprivation can lead to eye fatigue and insufficient blood supply, resulting in poor ocular blood circulation and congestion. It may also be accompanied by symptoms such as fatigue, difficulty concentrating, and dark circles. It is recommended to maintain sufficient sleep, avoid staying up late, and avoid using electronic devices before bedtime to prevent disruption of sleep quality.
4. Keratitis
Keratitis is an inflammation of the cornea caused by bacteria, viruses, fungi, etc. The cornea becomes infected, triggering a local inflammatory response, leading to vasodilation and infiltration of inflammatory cells, manifesting as eye congestion. It may also be accompanied by symptoms such as eye pain, photophobia, and vision loss. It is recommended to select appropriate treatments based on the underlying cause, such as Gentamicin Sulfate Eye Drops, Moxifloxacin Hydrochloride Eye Drops, etc.
5. Glaucoma
In glaucoma, impaired circulation of aqueous humor within the eye leads to elevated intraocular pressure, which compresses the optic nerve and causes eye congestion. It may also be accompanied by visual field defects. It is recommended to seek timely medical attention and follow medical advice to use intraocular pressure-lowering medications such as Carteolol Hydrochloride Eye Drops, Timolol Maleate Eye Drops, Pilocarpine Eye Drops, etc.
During treatment, appropriate therapeutic measures should be taken according to the specific cause. At the same time, attention should be paid to maintaining good lifestyle habits and ocular hygiene, avoiding excessive eye use and eye fatigue.
