I have a friend in India who has asked me to look into a problem he is having with his eyes.
When he wakes up most mornings he is completely blind (black vision) in both eyes for about 10 minutes. He has a burning sensation in his eyes. his sight only returns when he washes his eyes, and it takes about 10 minutes to come back. he has had very watery eyes and a burning sensation for most of the time for about 2 and a half years.
He went to an eye specialist in Delhi recently and was told that he was short-sighted but the doctor wanted him to have a brain x-ray to determine the cause of these symptoms. He cant afford to have the x-ray at the moment, and isn't sure it is necessary (doctors in Delhi are notorious for recommending unnecessary, expensive treatments). Any ideas what the cause of this could be and what he should do about it?
