I have a 75 yr old friend. What might cause one eye to be bloody red? Not just your average bloodshot.?

High blood pressure, popped vessel. It could be a number of things, usually not serious, but they should go to the doctor.

When I was younger about 17 I was jumped and since then my left eye has solided red around the curna. In short my left eye has no white just solid red from a bleeding blood vessel or something like that my doctor says. I also have a (conjunctiva) pterygium in the same eye he says maybe from that as well as other things. I could have surgery on both but think its cool lol so I won't. I love my eye it's so cool......

Sounds find it irresistible would be purple eye (conjunctivitis) name his surgeon for an appointment. You can use a hot rainy wash fabric to scrub his eyes within the morning, however he's going to ought to be obvious and handled. If it is purple eye you ought to allow his preschool recognise, and he would possibly not be allowed again to college till it is long past, most of the time with a word from the surgeon.

i will give the ans first u tell what is u r name
