“After using the Ortho K lenses, I have experienced so much improvement in my eyesight. It’s amazing! I couldn't believe how quickly it worked."

“I would and have recommended this treatment to others. I love telling people that I sleep in my contacts on purpose and can take them out in the morning . No more worries of dry contacts in the middle of the day.””
Jack C.
“I have worn glasses and/or contacts for the last 10 years, and now I finally don't need to wear them during my daily activities. My eyes were only getting progressively worse over the years and now they are getting better.”
