Swelling below the eye, along with redness, watering, irritation, or discharge, can occur due to conjunctivitis, an eyelid infection, an allergy, blocked oil glands, a sinus infection, or irritation around the eye tissues. Sometimes the swelling develops because rubbing the eyes repeatedly increases inflammation and fluid buildup around the delicate skin near the eyes. Cold compresses, proper eye hygiene, lubricating eye drops, and resting the eyes may help reduce irritation and swelling in mild cases. If infection is present, medicated eye drops or other treatment may be needed, depending on whether the cause is viral, bacterial, or allergic. Avoid touching or squeezing the swollen area, and do not share towels or pillows because some eye infections spread easily. Pain while moving the eye, fever, thick pus-like discharge, blurred vision, rapid swelling, or difficulty opening the eye can sometimes indicate that the infection is spreading deeper around the eye and may require immediate eye treatment and examination.

Viral eye infection can cause redness, watering, irritation, burning sensation, sticky discharge, and sensitivity to light. The infection usually improves gradually over several days, but irritation and watering may continue for some time even after the redness starts decreasing. Touching or rubbing the eyes repeatedly can worsen irritation and spread the infection further. Cold compresses, gentle eye cleaning with clean water, proper hand washing, and resting the eyes from screens may help improve comfort and reduce irritation. Lubricating eye drops are often used to reduce dryness and burning sensation. Drinking enough fluids, eating fruits rich in vitamin C, leafy vegetables, nuts, and maintaining good sleep may support recovery and overall immunity. Avoid sharing towels, pillows, eye cosmetics, or handkerchiefs because viral eye infections can spread easily within families. Very severe pain, blurred vision, swelling around the eyes, thick pus-like discharge, or increasing light sensitivity can sometimes happen when the eye irritation becomes more intense and may need proper eye treatment and examination.

Redness and watering of the eyes are commonly caused by viral eye infections, allergies, dust irritation, or conjunctivitis. Some people also experience burning sensation, itching, mild swelling, sticky discharge, or sensitivity to light along with the redness. Eye irritation may increase after rubbing the eyes or prolonged screen exposure. Lubricating eye drops and cold compresses may help reduce irritation, dryness, and watering in many mild cases. If an allergy is contributing, anti-allergy eye drops may also help reduce itching and redness. Keeping the eyes clean with fresh water, avoiding touching or rubbing the eyes, and resting the eyes from mobile or computer screens may improve comfort faster. Hand hygiene is important because some eye infections spread easily. Avoid using leftover steroid eye drops without proper guidance because they can worsen some infections. Thick yellow discharge, severe pain, blurred vision, swelling around the eyes, or increasing light sensitivity may mean the eye problem needs proper examination and treatment adjustment.
