The optometrist holds a special spot in all of our hearts, even if they aren't the most respected doctors. Out of all the doctors in the world, an optometrist is the one you want to see. No one is ever scared about going to the optometrist. Sure, it's annoying like running any other errand, but it's nothing like going to the dentist or the doctor. You go to the dentist and you know you're going to go through horrible pain. You go to the doctor and you might be told that you're dying. What's the worst that'll happen when you go to the optometrist? He'll say you're going blind, but that won't come as a surprise. You can see out of your own eyes after all.
There are many different options for optometrists that range from starting your own practice to working with a large company. If you wanted to forgo the risk of starting your own practice, that's perfectly fine and there are plenty of opportunities to do so. Here's the one catch though. You're going to need good eyesight. It doesn't make much sense for your optometrist to have bad eyes.
