Have specific questions about what to expect during your visit? Here are some detailed answers to help you feel more informed and prepared for your comprehensive eye exam at Vision Source.
The frequency of eye exams can vary based on age, health, and risk factors. The American Optometric Association suggests infants be examined at 6 months, children at 3 years and before school, and regularly every 2 years thereafter. Adults should have their eyes tested biennially from ages 18 to 60 and annually after 61. If you wear contact lenses or have risk factors for eye diseases, more frequent exams might be necessary.
An eye exam at Vision Source doesn’t include contact lens fitting as standard. If you’re considering contact lenses, please mention this when you book your appointment. We’ll ensure that you receive both a comprehensive eye health exam and a contact lens fitting when you come in, providing you with comfort and optimal vision.
A basic vision test typically only assesses your ability to see clearly at various distances, usually just using an eye chart. A comprehensive eye exam includes this test and much more. It involves a detailed examination of all aspects of your eye health and vision, including checking for common eye diseases, evaluating how your eyes work together, and assessing the overall health of your eyes.
Yes, comprehensive eye exams can be the first line of detection for several systemic health issues, including diabetes, high blood pressure, and even some neurological diseases. Our optometrists look for tell-tale signs in the blood vessels and structures of the eye that might indicate broader health concerns.
Bring any glasses or contact lenses you currently use, a list of any medications you’re taking, your medical and vision insurance information, and a list of any symptoms or concerns you have about your vision or eye health.
Typically, a comprehensive eye exam at Vision Source takes about an hour. This time allows us to conduct all necessary tests without rushing, ensuring we provide you with the best care and attention.
No special preparation is needed. But, if you’re a contact lens wearer, you might be asked to switch to glasses before your appointment. This can help with certain tests and make it easier to examine the front surface of your eyes.
