Morning blurred vision is blur on waking that often improves during the day. The cause is commonly related to the cornea, tear film, or overnight conditions.
Likely Causes
Corneal oedema from Fuchs’ endothelial dystrophy or contact lens overwear causes cloudiness that clears as the eye dries and pumps out fluid. Overnight dryness, incomplete lid closure, or sleeping in lenses also disturb the tear film and lead to blur on first opening the eyes.
- People with Fuchs’ dystrophy often notice misty vision and glare on waking
- Night‑time eye rubbing or exposure can trigger recurrent corneal erosions
- Thicker night‑time ointments can cause temporary blur until they disperse
- Uncontrolled sleep apnoea or fluid shifts can exacerbate morning oedema
When to Investigate
Persistently worse morning vision warrants corneal evaluation and review of lens habits and medications. Early treatment of endothelial or surface disease can protect long‑term clarity.
- Special drops, surface protection, or surgery may be recommended for corneal disease
- Good lid closure and humid bedroom environments support the tear film
- Sudden severe morning blur with pain needs urgent assessment
- Regular follow‑up monitors progression of any underlying disorder
