What are the causes of red under-eye bags?

Red eye bags can be caused by physiological factors, but they may also be due to diseases such as styes and blepharitis.

1. Physiological Factors: Patients who stay up late for long periods, use electronic devices excessively, or read in low-light environments may experience dry and painful eyes. At this time, the eye bags can become congested and red, accompanied by mild pain. After blood coagulation, dark circles may also form.

2. Styes: Patients who frequently rub their eyes, share towels with others, or do not pay attention to eye hygiene can allow Staphylococcus aureus to invade the eyelid glands, forming styes. At this time, the patient's eye bags can quickly become congested and swollen under the stimulation of inflammation, with visible soft boils and pustules locally, resulting in red eye bags.

3. Blepharitis: When patients are infected with Demodex mites, rub their eyes frequently, or experience sty swelling, it can lead to blepharitis. When stimulated by bacteria and Demodex mites, the eye bags become congested and swollen, accompanied by itching and a burning sensation. Ulcers and erosions may form locally, causing the eye bags to turn red.
