Comprehensive Eye Exam

Why You Need a Comprehensive Eye Exam

If you’ve had a recent vision screening, you might think, “My vision is fine! I don’t need a comprehensive eye exam.” However, a vision screening offers only a limited perspective on your eye health. It's similar to getting your blood pressure checked without having a full physical exam—you gain some useful information, but it's not the complete picture.

• Vision screenings only test for distance clarity.

Vision screenings primarily assess your ability to see clearly at a distance, known as visual acuity. This is just one aspect of your overall vision. Other important factors include color vision, peripheral vision, and depth perception. Screenings also do not evaluate near vision or how well your eyes work together. Most critically, they provide no information about the health of your eyes.

• Conducted by untrained individuals.

Vision screenings are often performed at schools, health fairs, work physicals, or for driver's license renewals by individuals without specialized eye health training. Even if conducted by a general physician, they lack the extensive training and equipment necessary for a complete vision and eye health assessment.

• Limited testing equipment.

Many vision screenings use only basic tools like an eye chart. Even screenings in a physician’s office do not match the comprehensive testing equipment found in an eye doctor’s office. Factors such as room lighting and testing distances, which can affect results, are not always adequately controlled.

Evaluates all aspects of vision and eye health.

A comprehensive eye exam involves detailed evaluations of both the external and internal structures of your eyes, along with various vision tests:

• External Exam: Evaluates the whites of your eyes, iris, pupil, eyelids, and eyelashes.
• Internal Exam: Involves dilating your eyes to assess the retina and optic nerve.
• Visual Function and Eye Health: Tests for depth perception, color vision, peripheral vision, pupil response to light, and evaluates focusing, teaming, and movement abilities.
• Glaucoma Testing: Measures fluid pressure within your eyes to check for glaucoma.
• Visual Acuity: Determines if glasses or contact lenses can improve your vision.

Considers your overall health history.

Your eye health is connected to your overall health. Dr. Li will review your general health and that of your immediate family, any medications you’re taking, and whether you have conditions like high blood pressure or diabetes. They will also ask about smoking habits and sun exposure. These factors help in accurately assessing your eye health.

Regular eye exams recommended.

The American Optometric Association recommends an eye exam every two years for adults aged 18-60 if you’re not experiencing any issues. After age 61, annual comprehensive exams are advised, or as recommended by Dr. Li.

Taking these steps ensures your vision remains sharp and your eyes stay healthy. Schedule your comprehensive eye exam with Dr. Li to maintain optimal eye health.
