My sclera is blueish grey on the left eye. Is it a problem? Also, I sleep late playing on my phone until 5:00am

Blue sclera. As for the blue sclera, see your physician and potentially a geneticist. There are a variety of bone and cartilage disorders which are associated with blue sclera. Regarding the sleeping late, I would recommend shutting off your phone and all tech screens at LEAST one hour before you plan to go to sleep. Warm bath, dark light, books, bed.
