Swelling in one eye may be caused by a mild eye infection, such as a stye or conjunctivitis. An allergic reaction to dust, pollen, or cosmetics may also lead to swelling, often accompanied by itching. Sometimes, fluid can collect around the eye due to lack of sleep, excess salt intake, or rubbing the eye. Insect bites or minor injuries may also cause local swelling. In many cases, the swelling is mild and settles on its own within a day or two. You can try simple measures such as applying a clean, cool compress, avoiding rubbing the eye, and keeping the area clean. If you suspect an allergy, avoiding the trigger may help. However, if the swelling worsens, becomes painful, affects your vision, or is accompanied by fever or significant redness, please see an eye doctor for an examination and appropriate treatment, if required.

Tearing and mild eye discharge are quite common in newborns, especially in the first few weeks of life, and are usually not serious. The most common cause is a blocked tear duct, which means that tears are not draining properly from the eye into the nose. This can lead to watering and a small amount of sticky or yellow discharge, especially after sleep. In most cases, this condition improves on its own over a few weeks or months as the tear duct opens naturally. You can help by gently cleaning your baby?s eye with clean cotton soaked in warm water. Always wipe from the inner corner of the eye outwards and use a fresh piece of cotton each time. Gentle massage over the inner corner of the eye, near the nose, may also help open the tear duct. However, you should watch for signs such as redness of the eye, swelling, or excessive discharge, as these may indicate an infection and require medical attention. If the problem persists for several weeks or worsens, it is best to consult a doctor for a thorough examination and guidance.

Waking up with tired, sore eyes and mild pain is a common problem and can have several simple causes. One of the main reasons is the dryness of the eyes during sleep. When your eyes do not produce enough tears or do not stay fully closed at night, the surface of the eye can become dry and irritated by morning. Another common cause is eye strain, especially if you spend long hours on screens such as phones or computers. This can tire your eye muscles, leading to discomfort when you wake up. Poor sleep quality, allergies, or sleeping in an air-conditioned or dusty environment can also contribute to morning eye soreness. Sometimes, conditions like blepharitis, which is inflammation of the eyelids, may cause irritation and mild pain upon waking. To reduce symptoms, try getting enough sleep, limiting screen time before bed, and keeping your room clean and well-ventilated. You can also use artificial tear drops if dryness is a problem. If the pain becomes severe, if your vision changes, or if redness and swelling develop, please consult a doctor for proper evaluation and treatment.
