One line of red in my eye for at least 13 years (I'm 25)

Its just a blood vessel and if its not irritable or sore there isnt much you can do about it. As we grow older , the blood vessels near the surface of the eye can become more noticeable especially after an eye infection or if the eye is irritated due to a foreign body. I think maybe yours became more noticeable due to body changes in puberty.Dont worry about it.

I have the same problem i had this just 2 years ago and i cant seem to get rid of it, been to a few doctors and they just gave me the same eyedrops that didnt get the red line out, the eyedrop is hypromellose just to keep my eyes from getting dry. The other doctor suggested not to have it removed since its normal for some people to have it, Im just bothered by the way it looked and i get conscious a lot of times when people look me in the eye. I just want to have it removed.

You could try one of the eye drops which claims to make your eye whites whiter. They usually have a reference to blue . Only buy a reputable make. They are not a cure but are a cosmetic.

I've done research on this and what they say is that it will give you rebound redness overtime. Mine looks actually worse its more visible from the corner of my right eye going straight down.

I don't know yet, i hope not I'll have it checked again once quarantine is over. I'll let you know by then. Btw where are you from? Did you already see an opthalmologist?

I would not be overly concerned unless there is pain, decreased vision or increased redness and in that case seek medical assistance now.

Once routine eye examinations restart the best advice is to go for a full eye examination .
