Refresh Optive Mega-3 Lubricant Eye Drops are uniquely formulated with flaxseed oil to address all three layers of the tear film, providing comprehensive dry eye relief. The lipid-enriched formula helps stabilize and replenish the outer lipid layer of the tear film that prevents excessive evaporation. Clinical studies demonstrate sustained improvement in dry eye symptoms with regular use. Preservative-free vials ensure compatibility with the most sensitive eyes.
