Why can't I see in the morning?

Beginning about 6 months ago I have noticed my vision is blurry in both eyes for about two hours after I wake up. I can’t see anything close up or far away. Squinting doesn’t help. It’s like there’s sleep in my eyes. They aren’t red or itchy. After a couple of hours, sometimes less, my vision for the rest of the day goes back to 20/20 or better. Eagle eyes.

What do you think causes this? Is it something I can correct?
