ELI5:Why does closing your eyes after your alarm wakes you up feel so good?

Like you're not even asleep yet but it feels amazing compared to ur eyes being opened.

The tear film on your eyes is reduced while your eyes are closed during sleep. If your bedroom is air-conditioned, the low humidity can make this even worse. When you first open your eyes, the reduced tear film dries out quickly and closing them helps redistribute the liquid that's left. 

BTW, you may notice that your eyes do not focus as well when you first wake up - this is also due to the fact the the tear film is reduced or momentarily absent. Your eye's focusing system depends on the different refractive indices between each layer, i.e., from cornea to tear layer and from tear layer to  air, and is not as effective when the transition is directly from cornea to air.
