I’m a 20 year sufferer of MGD, Blef,dry eye and have tried countless products, drops, services like Lipiflow, cauterized ducts, IPL (over 20 sessions), doctors, surgeries, gland probing, etc. I bought this with very low expectations. I've tried it all and hope is not a luxury I give myself often. I have been using the Nulids device for two weeks. I'm stunned with the results as I thought I was good with lid hygeine after all Ive been through. My eyes feel so good like never before. I can literally feel the oil coat eyes from glands that have been clogged. This is not a magic bullet cure but something I now can't live without that is a part of my daily maintenance plan. My eyes are so much clearer - even white much of the time during the day after my morning routine settles down. I would highly recommend this product as it has changed my world for the better!
