It’s simply your visual system becoming worn out from general tiredness. The muscles in your eyes are becoming tired and are trying to relax which causes the blurry, out of focus vision. The same thing happens when you’re very relaxed, intoxicated, or when you first wake up. Anything that causes the muscles in your eyes to relax will have this effect.
