I have not been wearing contacts for more than 6 years now. I started when I was about 16 years old and fully stopped when I was 19 years old. So about a total of 4 years of contacts. When I was 18 years old I wore my monthly contacts for more than 2 months which towards the end of the 2 months. The contacts caused irritation in my eyes. This is when my eyes started to get red and I became unable to have a contact lens in my left eye due to discomfort. But doctors did not find anything wrong. I noticed some new blood vessels on the white of my eye at that point. What I wonder about now is if the new blood vessels were created by lack of oxygen or by the irritation? No doctor has ever told me that I have blood vessels on the cornea itself, I'm referring to red blood vessels on the white part of the eye.
Decreased oxygen and irritation can certainly cause more blood vessels to grow on the cornea, and increased redness. It sounds like you are experiencing contact-lens intolerance, which would respond to decreased weartime, mild steroid drops, or a change in contact lenses. Make sure you have an EyeMD seeing you in addition to your optometrist.
