Simple vision screenings give limited insight into the health of your eyes, much like getting your blood pressure checked but not getting the rest of your annual physical. On the other hand, a comprehensive eye exam provides a complete perspective into your overall eye health by factoring in much more information about your eyes and general health.

The Benefits of a Comprehensive Eye Exam

Comprehensive eye exams evaluate all aspects of your vision and eye health, examining your eyes internally and externally for any signs of eye disease. These tests include:
​​​​​​​

• External exams, an evaluation of the whites of your eyes, the iris, pupil, eyelids, and eyelashes

• Internal exams, an evaluation of your retina and optic nerve while your eyes are dilated

• Visual function and eye health tests, an evaluation of your depth perception, color vision, peripheral vision, and the response of your pupils to light.

• Glaucoma testing, an evaluation of the fluid pressure within your eyes to check for the possibility of glaucoma

• Visual acuity, an evaluation determining if glasses or contact lenses can improve your vision

They treat eyes holistically, factoring in your overall health history including your blood pressure, the amount of sun exposure you get, and whether or not you have diabetes, smoke, or take medications.

The Limitations of a Vision Screening

They only test visual acuity, or your ability to see clearly in the distance, and they do not provide insight into the health of your eyes.

They are typically conducted by individuals untrained in eye health at your annual physical, school, work, or other places lacking extensive testing equipment.

The test is frequently limited to an eye chart across the room, which fails to test various distances and take into account factors like room lighting which can affect test results.

The American Optometric Association (AOA) recommends that adults between the ages of 18 and 64 get an in-person eye exam every year regardless of their eye health
