Dear Dr. Thomas Azman,
I want to thank you gratefully on giving me a perfect opportunity to pass my color vision test. The contacts were a success and therefore, I passed my full medical exam. Your determination and professionalism has allowed me to enhance my career and free my worries about any future vision test. At first, when I found out about my color vision problem I lost hope about any job of my expectation. However, You changed that and therefore you changed me for the better.
Thanks again for your dedication!
Thomas
