Comprehensive Eye Exam

If you’ve had a vision screening recently, you might say, “My vision is fine! I don’t need a comprehensive eye exam.”

But a vision screening provides a limited perspective on the overall health of your eyes. It’s a bit like getting your blood pressure checked and not getting the rest of your annual physical. You’ll have useful information, but it’s not the whole picture.

The American Optometric Association recommends an eye exam at least every two years if you aren’t having any problems and you’re aged 18-60. After the age of 61, you should schedule a comprehensive exam annually or as recommended by your eye doctor. Contact lens wearers need an annual eye exam and most vision insurance covers yearly exams for all ages.

For children, experts estimate that one in five preschool children have a vision problem and one in four school age children need or wear corrective lenses. Undetected and untreated eye and vision disorders can make learning difficult and affect children in school. In-person comprehensive eye exams provided by an eye doctor are recommended yearly.  At Oswego Optique we will happily see your school-age child, but recommend a pediatric office for younger children.
 

What are the Benefits of a Comprehensive Eye Exam?

Comprehensive eye exams evaluate all aspects of your vision and eye health.
The comprehensive eye exam looks at your eye externally and internally for any signs of eye disease, then tests your vision in a variety of ways.

• External Exam – This is an evaluation of the whites of your eyes, the iris, pupil, eyelids, and eyelashes.

• Internal Exam – This is an evaluation of the retina and optic nerve. 

• Visual Function and Eye Health – This includes testing depth perception, color vision, peripheral vision, and the response of the pupils to light, as well as an evaluation of eye focusing, eye teaming, and eye movement abilities.

• Glaucoma Testing – This is a test of fluid pressure within your eyes to check for the possibility of glaucoma.

• Visual Acuity – Your doctor will test your vision with different lenses to determine if glasses or contact lenses can improve your vision.
   

Comprehensive eye exams look at your total health history.
Even though you visit a separate office for your eye health, that doesn’t mean your eyes shouldn’t be treated holistically. Your eye doctor will discuss your overall health and that of your immediate family, any medications you’re taking, and whether you have any conditions that can create a higher risk to your eye health like high blood pressure, diabetes, or a history of smoking. All these factors help the eye doctor properly assess your eye health.
 

What are the Limitations of a Vision Screening?

Typical vision screenings only test your ability to see clearly in the distance. This is called visual acuity and is just one factor in your overall vision. Others include color vision, peripheral vision, and depth perception. The screening also doesn’t evaluate how well the eyes focus up close or work together. Most importantly, it doesn’t give any information about the health of the eyes.
 

Vision screenings are conducted by individuals untrained in eye health.

Vision screenings are offered in many places – schools, health fairs, as part of a work physical or for a driver’s license. Even if your physician conducts the screening, he/she is a generalist and only has access to a certain amount of eye health training. Most individuals don’t have the tools or knowledge to give you a complete assessment of your vision or eye health.

Vision screenings use inadequate testing equipment.
In some cases, a vision screening is limited to an eye chart across the room. Even when conducted in a physician's office, they won’t have the extensive testing equipment of an eye doctor.
