A comprehensive eye exam is the best way to prevent vision problems in the future, and to catch any issues before they become worse. While you think that you would probably notice if your eyesight were to get worse, there are many other vision and health problems that are screened at a comprehensive eye exam. Most of these problems don’t exhibit any noticeable symptoms, often going undetected unless a qualified optometrist tests for them. An eye exam is typically separated into two parts: the Eye Health portion, and the Vision Examinationportion.
EYE HEALTH PORTION
With the help of the latest instruments and technology, a comprehensive eye exam can test for several vision problems as well as general health issues. By measuring things such as eye pressure, curvature of the cornea, and evaluating the eye’s lens, retina, and posterior section (through dilation of the pupils), an optometrist can test for:
- Macular degeneration
- Health problems such as high blood pressure and diabetes
Advanced testing instruments have improved the ability of an optometrist to test for many of these vision problems. For example, using the GDX Screener, an optometrist can detect glaucoma and optic nerve damage much earlier than was previously possible.
VISION EXAMINATION PORTION
The vision portion of your examination utilizes reading charts (where you read off letters from a chart at a distance) to test your visual acuity. The vision examination will determine if you need glasses or an update to your prescription. However, during this portion we also test for:
- Contact lens fit
- Color vision
- Depth perception
- Ocular muscle coordination
- Whether you are a good candidate for laser vision surgery
Even if you are not experiencing any noticeable problems with your vision, it’s recommended that all adults receive a comprehensive eye exam at least once every year. Be proactive when it comes to your vision, and schedule your Dallas eye exam today!
