Optometry is a healthcare profession that involves the examination, diagnosis, and treatment of visual disorders and diseases of the eye. Optometrists are trained to perform comprehensive eye exams, prescribe eyeglasses and contact lenses, and diagnose and treat various eye conditions such as glaucoma, cataracts, and age-related macular degeneration. Optometry is a rapidly evolving field, and optometrists play a critical role in helping people maintain good eye health and vision.
Optometry is an important and fascinating field, with a rich history and a wide range of knowledge and skills required. From the anatomy and physiology of the eye to the latest advances in technology and treatment, optometry offers a wealth of information to learn and explore.

Take Water Cooler Trivia for a test run with our four-week free trial.
We do everything we can to ensure that Water Cooler Trivia's questions are appropriate, relevant, and accurate. Our database has tens of thousands of questions, so we don't always get it right. If you see a question that needs editing, we would love if you let us know here or email quizmaster@watercoolertrivia.com.
