I woke up from an afternoon nap with my right eye blurry. When I only use my left eye or use both of my eyes, my eyes are fine.
It has been an hour since I woke up and my right eye is still blurry.
Thanks for your Question
Most likely you have pressure induced blurred vision. Most likely you slept on your right side and your head under your face and press on your eye. It usually resolve within hours and if not you should visit an eye doctor.
