2 Pack - Biotrue Hydration Boost Eye Drops for Irritated, Dry Eyes in Single Dose Vials from Bausch Lomb, Instant Moisture... I, personally, didn't find this anymore helpful than the rest for my chronic dry eye. I ordered it on my eye doctor's advice. My insurance doesn't cover prescription eye drops so I've been trying them all. If you have chronic dry eye and none of the single ingredient drops are working for you, may I suggest Refresh Digital Preservative Free Vials? I've used these before and with 3 lubricants, it helps so much better than the single ingredient lubricant drops which I think should be used for the occasional dry eye, not chronic.
