I have suffered from severe dry eyes for almost 2 years and have tried every product on the market to get relief. Since I switched to using I-DROP® PUR GEL, the condition has improved dramatically. I-DROP® PUR GEL is much more durable than any other product designed for use during the day. It is also compatible with my scleral lenses without causing blurry vision. It relieves redness and the burning sensation that I used to feel throughout the day. In my opinion, the I-DROP® PUR GEL is truly the best eye drop on the market. Every time I visit my optometrist, I stock up on I-DROP® PUR GEL. Thanks I-MED Pharma for this amazing product!
