I have used this product just because I wanted to use a natural treatment to cure my eye sight and wanted to keep my eyes away from other eye drops. so I have been using it for a couple of months now but recently stopped. seriously, I still can’t see any improvement at all rather it burns so much as it contains lemon juice, honey, onions etc.It is useful to clean eyes if some kind of dirt is there in your eyes but it didn’t improve my eye sight.
