At Delaney Eye Center, we strive to provide comprehensive, primary eye care for the whole family. Preventive and routine eye exams are important for maintaining good eye health. Often, eye and vision problems do not have obvious symptoms or signs but are easily diagnosed by a licensed optometrist. By diagnosing eye and vision conditions early on, our optometrist is able to provide treatment options and in many cases restore or prevent vision loss. The American Optometric Association recommends yearly or bi-yearly eye and vision exams, depending on whether you are at-risk or not.
