I heard somewhere a long while ago, that a certain condiion was spotted and prevented early, through noticing 'red eye' in photos of their child.
Can anyone tell me what that condition was? Is it serious and should I advise my friend, as I have noticed alot of red eye in her 1 yr olds pictures.
I do vaguely remember this story but I thought it was spotted becasue red-eye did not show up in one eye in photos (which is a normal effect from flash). I thought the bad eye looked blackish - I could be wrong.
'Red eye' is caused by light from the camera's flash reflecting off the blood vessels at the back of the retina. It's perfectly normal if a person is facing towards, or at a slight angle to, the light source.
"Red eye" is as Ratter just said, a common result of flash use in photography.
It is not a sign of any condition afaik. What you have picked up is probably based on the notion that if red eye DOESN'T happen in photos of children (or does in one eye only) there may be something up.
