2 Ways: The most effective and tempting way is not recommended: using drops that 'get the red out', like the original version of visine and clear eyes. These drops make bloodshot eyes white by constricting blood vessels, but they are highly addictive. Your eyes can become more red once you try to stop. Using non-medicated lubricating drops frequently, is a less effective but much better way to go.
