There are many benefits of Ortho-K. I love this treatment because of the convenience of wearing contacts at night while sleeping, instead of daytime, for contacts may interfere with your daily activities and social life. When I was still wearing glasses at age 8, I felt like I was fighting with a nefarious devil all day long. Now I can experience euphoria every day without heavy metal glasses hanging on my face. I am very grateful for the invention of Ortho-K, this treatment has helped me through my daily life and it will keep on helping me day after day, and year after year.
