I have been using Ortho-K contact lenses for about 2 1/2 years, and I love them. They are easy to use. At night, I put them in before bed, take them out in the morning, and the next day my vision is 20/20 all day long. They are easy to take along with you when traveling. When I am active, I dont have to worry about clumsy glasses anymore. I would recommend Ortho-K to anyone that is active and doesnt want to wear glasses.
