Features: 2 Bottles, 7.5 Milliters Each FDA Approved Brimonidine Tartrate Opthalmic Solution 0.025% Works in 1 Minute and Lasts up to 8 Hours LUMIFY works differently than other redness relievers by selectively targeting redness† and avoiding some of the potential side effects common to redness relievers — rebound redness and loss of effectiveness over time – when used as directed. LUMIFY significantly reduces redness to help your eyes look whiter and brighter. Approved by the FDA, LUMIFY is the first over-the-counter eye drop to contain the active ingredient brimonidine tartrate (0.025%).
