Symptoms of Allergic Conjunctivitis

Allergic conjunctivitis is an inflammation of the conjunctiva caused by allergens, with diverse and significant manifestations. The main symptoms include: 1. **Itchy eyes**: As the most typical symptom, itchy eyes often cause patients to rub their eyes or blink frequently, especially at night or after exposure to allergens. 2. **Conjunctival hyperemia**: Dilation of superficial conjunctival blood vessels leads to diffuse redness of the eye, which is a vascular response caused by the allergic reaction. 3. **Increased secretions**: Patients with allergic conjunctivitis often experience increased eye secretions, which are usually mucous or watery in nature and may cause a sticky sensation in the eyes. 4. **Photophobia and tearing**: Some patients may become more sensitive to light, experiencing photophobia, accompanied by excessive tearing. 5. **Eyelid swelling**: The eyelids may swell due to the allergic reaction, further aggravating ocular discomfort and sometimes affecting vision. 6. **Other discomforts**: Such as a foreign body sensation or dryness, which are also common symptoms of allergic conjunctivitis. If the above symptoms occur, it is recommended to seek medical attention promptly for targeted treatment.
