For the last two days I've been noticing that when I wake up my right eye is bright red. At first I thoughts it's an infection but by noon it disappears. Next night when I went to bed, my eyes were again sore at night. When I woke up at 2 am again it was red. This.morning too it was red but a few hours later it's gone. I don't have any other symptoms. Some side notes. - I live in delhi and can't tolerate much cold and use room heaters ( dry heater or blower which does irritate my skin, throat, eyes sometimes). - I did read somewhere it could also be if eyes aren't shutting properly but.thye seemed ok. I did hav bells palsy five years ago when I couldn't close one eye for a few weeks. But those things got better in 2016 itself.
