Bloodshot eyes are eyes with noticeable blood pigments and swollen blood vessels. You generally get bloodshot eyes from lack of sleep.
When I wear lashes with my contacts I find my eyes get tired and bloodshot after a few hours.
no, it would not cause your eyes to be bloodshot. Bloodshot eyes come from inflammation of the conjunctiva (the mucus membranes over your eyes/eyelids). Thinning of the blood could not cause conjunctivitis (bloodshot eyes) unless you have an allergy to that medication that could cause bloodshot eyes (which I would think would be almost impossible).
