I (24 M) wear Proclear Toric lenses, which I understand have less oxygen permeability (27 according to the fact sheet) than newer silicone hydrogel lenses. I wear them for about 12-18 hours per day, and I never sleep with them.
A couple months ago, I noted a prominent red blood vein in my right eye. It doesn't reach my cornea, and is only on the white part of my eye. I've heard that veins can invade the cornea due to a lack of oxygen from contact lens use. Is a vein like this something to worry about?
My last eye appointment was 8 months ago, and I've started to wear glasses when I'm at home to reduce my contact lens wear time. I know I'm probably concerned about nothing, but I thought I'd ask. Can new veins in the white of the eye be a sign of something worse in contact lens wearers?
