These drops are exactly what the doctor ordered. They lubricant the eyes perfectly. One drop each eye 2-3 times a day for moderate dry eye. These are the same drops my father used per his doctor. I believe the quality of these drops are outstanding. Packaging is secured to ensure no tampering. I really like these drops.
I've been dealing with dry eyes for a while now, and finding a reliable solution has been quite a journey. While I've given TheraTears Extra Dry Eye Therapy Lubricant Eye Drops a solid 4-star rating, I've noticed that the initial soothing sensation after application could be a bit longer-lasting, as I do find myself needing to reapply them more frequently than I'd like. Overall, I'm pleased with my purchase.
