Hi, my right eye becomes reddish in the cornea area if I sleep less than 6 hours. Normally for others both eyes become red but I get this issue in the right side only. Also the condition persists even after good sleep the next day or after that for 2-3 days. I am working night shift (rotational) for the past 2 years. This occurs once or twice in four months as working in night shift I have less sleep most of the days and my eyes are fine (though tired). I have checked symptoms online and it says hypoxia and few suggest corneal neovascularization. Please help.
