The main reasons why eyes may hurt upon waking up include dry eyes, eye infections like conjunctivitis (pink eye), eye allergies, inflammation of the eyelids (blepharitis), eye strain, and eyelid issues such as incomplete closure during sleep (nocturnal lagophthalmos). Other contributing factors can be environmental conditions like dry air or sleeping with fans on, wearing contact lenses overnight, and sinus infections causing pressure around the eyes. These conditions can cause symptoms like redness, dryness, itchiness, a gritty sensation, pain, and light sensitivity upon waking.

Common Causes of Morning Eye Pain

• Dry Eyes: Tear production decreases during sleep, leading to dryness and irritation in the morning.
• Eye Infections: Conditions like conjunctivitis can cause redness, pain, and discharge.
• Allergies: Allergens on pillows or in the environment may irritate the eyes overnight.
• Eye Strain: Excessive screen time before bed can overwork eyes, causing discomfort.
• Eyelid Issues: Lids not fully closing during sleep exposes eyes to dryness and irritation.
• Environmental Factors: Air conditioning, fans, or dry indoor air can dry out eyes.

When to Seek Help

Persistent, worsening, or severe eye pain along with other symptoms such as vision changes or intense redness should prompt a visit to an eye care professional for a thorough examination and targeted treatment. Thus, eye pain on waking is commonly related to dryness, irritation, or underlying eye conditions that require appropriate care or lifestyle adjustments.
