Continuous use of vasoconstrictor eye drops such as Visine is unwise.
Dry eyes? Use a preservative-free artificial tear supplement.
Repeated use of vasoconstrictors causes REBOUND REDNESS. Once the drugs’ chemicals wear off, the previously constricted blood vessels relax, dilate and cause even more redness. Over time vasoconstrictors, like many eye drops, lose their potency. The eye drops fail to perform as well as when first used. Vasoconstrictor eye drops should be used sparingly for special occasions, like an important photograph or severe allergy.
