You are helping people see. Without you, people get headaches, are stressed out, can't drive and can't work. 20/20 vision is a godsend to those who don't have it. That makes you a god. Try to keep things in perspective. Optometrists are famous for their volunteering and charitable community work. If you want glory, use your free time to travel to countries or areas of the country where vision means the difference between a life of poverty and a life of schooling and employment. Diagnosing or treating glaucoma and macular degeneration will provide a lot of relief for older adults. You know how medical marijuana is a common treatment for glaucoma? Many states are now passing laws allowing optometrists to write prescriptions, so you could have a real marketing magnet right there.
