I received my free box of contacts and tried out a pair a few days ago. The left contact seemed uncomfortable, and I had to take it out after only about 6 hours. I put my regular contacts in the day after that and left them in for my usual amount of time, 15 hours. They were comfortable all day.
I tried the Hubble Contacts again the next day, and although I was able to leave them in about 10 hours, they became very uncomfortable again, and they made my eyes feel very dry. I guess as an emergency pair they would be okay, as long as you didn't need them for more than 6 hours or so.
Needless to say, I was very disappointed and now have to wait until I can call Hubble to cancel (you can't cancel online).
Bottom Line: No, I would not recommend this to a friend
