When eyes burn upon waking up, it is most commonly due to dryness. During sleep, tear production naturally decreases, which can lead to insufficient lubrication of the eyes and cause a burning sensation. Other common causes include allergies to dust mites or pet dander in the bedroom, inflammation of the eyelids (blepharitis), exposure to dry air from fans or air conditioning, sleeping with contact lenses, poor sleep quality, or eye strain from excessive screen time the day before. These factors can irritate the eyes overnight, resulting in burning, redness, and discomfort upon waking. More specifically:
- Dry eye syndrome occurs when the eyes do not produce enough tears or when tears evaporate too quickly overnight, leading to a stinging or gritty feeling.
- Allergens in bedding or the room can inflame the eyes.
- Blepharitis causes inflammation and crusting on eyelids, causing burning sensations especially in the morning.
- Environmental dryness from airflow (like fans or heaters) can dehydrate eyes during sleep.
- Improper contact lens use and eye infections can also contribute.
- Eye strain from late-day screen use may carry over as morning discomfort.
If burning eyes persist, consulting an eye specialist is recommended for proper diagnosis and treatment.
