I first came to Zacks because I was worried about my son’s progressive myopia when he was just 8 years old. Every 6 months his prescription was increasing and already -4.00 at such a young age. We were recommend to see Jonathan by a friend whose child had similar issues. Jonathan is very professional and did a very thorough examination. We discussed the treatment options and decided to try Orthok. I am so glad we did because since starting the treatment my sons prescription has hardly changed in 4 years. Being free from glasses also helps him with sports, especially swimming, his favourite.
