If you wake up with blurry, foggy vision in the morning that slowly clears as the day goes on, it’s not just “sleepy eyes.”
This can be a sign of Fuchs Endothelial Corneal Dystrophy.
In this condition, the innermost layer of the cornea (called the endothelium) doesn’t work properly. These cells normally pump excess fluid out of the cornea to keep it clear. Over time, they slowly reduce in number, allowing fluid to build up.
At night, when your eyes are closed, evaporation decreases and fluid accumulates in the cornea. This causes corneal swelling, which is why vision feels hazy or foggy on waking. As the day progresses and your eyes stay open, evaporation improves and vision often clears temporarily.
Don’t ignore morning blur. Early diagnosis helps manage symptoms and protect long-term vision.
If this sounds familiar, an eye check can make all the difference. 👁️
