I purchased the Ice walker contacts and had only had them for 8 months. I put them in a few nights ago for a Halloween Ball and only wore them for 6 hours. I got home and took them out and went to sleep. The next morning when I opened my eyes, my eyelids tore off 50% of both of my Corneas. These contacts weaken and starved my eyes of oxygen and then my corneas were extremely damaged because of it. DO NOT PURCHASE! I was in extreme pain and unable to open my eyes for days after this horrific experience! I'm going in tomorrow to check if I have permanent eye damage. Do Not Buy from here!
