Ocular discomfort characterized by a gritty, scratchy, or burning sensation upon awakening is a common experience. Individuals may also report blurry vision that gradually improves after blinking several times. The underlying cause is often insufficient tear film lubrication during sleep, leading to dryness and irritation of the cornea and conjunctiva.
Maintaining adequate ocular surface hydration is crucial for clear vision and overall eye health. Discomfort upon waking can disrupt sleep patterns and impact daily productivity. Historically, such symptoms were often dismissed, but contemporary understanding acknowledges the significance of addressing nocturnal dryness to prevent chronic conditions and improve quality of life. Environmental factors, underlying medical conditions, and certain medications can contribute to this phenomenon.
