I'm sorry I'm posting again but I can't stop worrying about my son (19 yrs old)
I noticed today that he has a red line in the white part of his eye. It goes from the inner corner over to his pupil. I'm in a panic over it, thinking the worst.
I'm falling down the eye cancer route and I can't stop it. I don't even know if a red line like that is a sign of eye cancer.
Has anyone had a red line like that just appear? What can cause it?
It's definitely fairly new, wasn't there a week or two ago.

The last time he went to see an optician was about 6 months ago. He just went for a routine eye exam as he needed new glasses.
The optician told him then that his eyes looked fine, but it was 6 months ago.
