I am sorry to hear that you get subconjunctival hemorrhage. If you want to do something good to your eyes, you's better not wear contact lenses in this moment.

No, it is not okay to wear contacts with a subconjunvtival hemorrhage. Having a subconjunctival hemorrhage means your blood vessels bursts in the eye and leads to some of the white part of your eyes turn red.

As far as I know, a lot of people get the same problem or trauma with you due to their carelessness and bad living habits. Actually, subconjunctival hemorrhage is one of the most complicated and dangerous eye problem you will encounter. Therefore , it would be unwise if you insist on wearing contact lenses even if you are sick. Of course it is extremely harmful and the contact lenses would scratch the retinal again.
