These are drops that are meant to make your eyes “whiter”. The most popular here is Eye gene. It’s important to remember that these drops simply make your blood vessels thinner, therefore making your eyes look less red. They do not address what caused the redness in the first place. Conditions such as allergies, infections, dry eyes, eye strain caused by prolonged computer use, astigmatism and farsightedness; can all result in red eyes, get your eyes examined to find the true cause. Prolonged use of these drops results in the opposite effect, that is, they end up making your eyes more red over time.
