Use travatan for 7 months and am experiencing eye color change & bloodshot eyes. Is there anything I can use to counteract the bloodshot eyes?

Stop the medicine. Both the eye color change and the bloodshot eyes are unwanted side effects from travatan. Your ophthalmologist will need to change you to a different type of medication to lower eye pressure.
Not really. Unfortunately there is not anything you can do about the iris color change, even if you stop travatan. As for the redness, i'd advise non-preserved artificial tears as it will soothe the eyes. I don't recommend vasoconstrictor agents like visine, which are likely to cause rebound redness if overly used., ; they only mask the redness. Only stopping travatam will eliminate the redness.
