Comprehensive Eye Exam
During your eye exam the optometrist will not only evaluate your eyes for visual correction (whether or not you need eye glasses or contact lenses), they will also be checking the overall health and function of your eyes.
Many eye diseases have very miniscule or slow progressing symptoms which cannot be detected without a comprehensive eye exam. It is important to catch eye diseases during their early stages, as some diseases, like glaucoma, are irreversible. Fortunately, early detection can make it significantly easier to manage the disease, and preserve vision.
