Once I woke up with an eye that looked like that. Amazingly it did not hurt at all, although it looked horrible. I did searches on that condition and it can be caused by a tiny broken blood vessel in the eye, without any pain, or even discomfort, and will often resolve on it’s own very quickly. I think mine lasted 2 days. Just went away.
His might be that, or something else. But if I were a public figure, I would certainly not appear in public with an eye that looked like that.
