About Optometry

Know any good quotes about optometry or optometrists?
I have to give a speech about the subject tomorrow morning for high school and I'm have trouble ending it. I was thinking a quote, but if you know something better, tell me. It's about what optometrists do, the training they go through, their salary, etc. and why being an optometrist would be rewarding.

Question about optometry prescriptions etc?
So I lost my glasses in June. I put off doing anything about it for over three months. I finally ordered new glasses online, using my old prescription which was already almost two years old when I lost them. When I put them on, the right eye seems waaay different than it was before. Which do you think is more likely...a All the eye strain from going w o glasses for over three months made my right eye prescription change drastically.b The eyeglass manufacturer screwed up.

Does anyone know of any good novels about Optometry?
Either a fictional book about an optometrist, maybe a story of what it's like being an optometrist, or even an informational book about optometry?
