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.

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.

Continuous irritation in the inner corner of the eye for a couple of days may be caused by dryness of the eye, dust or a small foreign particle, a mild infection, or blockage of the tear duct. Sometimes, frequent eye rubbing or exposure to screens, smoke, or pollution may also lead to this discomfort. You can start with simple care at home. Gently wash your eye with clean water to remove any irritants. Applying a clean, warm compress over the closed eye for five to ten minutes a few times a day can help soothe irritation and improve tear flow. Try to avoid touching or rubbing the eye, as this may worsen the problem. Using preservative-free lubricating eye drops may also provide relief. If you notice redness, swelling, discharge, pain, or blurred vision, or if the irritation does not improve within a few days, please consult an eye doctor for examination and appropriate treatment.
