Why cant you see clealy when you wake up in the morning?

When you wake up in the morning, your vision may be blurry due to several factors. One common reason is that your eyes may be dry from sleeping, as tear production decreases during the night. Additionally, the eyes might be adjusting to changes in light and focus after being closed for several hours. Other factors, like sleep inertia and temporary changes in eye shape, can also contribute to this temporary lack of clarity.
