Best Answer

Visine has an active ingredient which reduces redness by shrinking the blood vessels. (also known as a vasoconstrictor) These same blood vessels are responsible for bringing oxygen and nutrients to your eyes. So, basically it's like shrinking a fire hose to a garden hose to put out a fire. (Visine should be used very sparingly) If you have persistent redness, you have other eye problems that need to be addressed by your eyecare professional.
