Wouldn’t a Vision Screening at a Local Health Fair Cover an Eye Exam?

What to know about Vision Screenings | Clio, Michigan

Numerous studies have shown that quick vision screenings at health fares are nowhere near as effective as an in-house eye exam. Screenings have a significant percentage of being wrong on their diagnosis. For instance, they can falsely identify somebody with a potential problem panicking a parent over nothing. Another potential problem is when a vision screening claims a person has a normal vision when truthfully, they do not. This is the worst-case scenario that a parent can have a sense of assurance and peace of mind and feel an in-person eye exam is unnecessary. They may go for years without a real eye exam, and live years with an undiagnosed vision disorder, eye condition, or learning disorder.

Eye exams are the key to good eye health - not vision screenings

No matter what, a vision screening at a local far can never address the level of testing or analysis of an actual eye exam. Most advanced technology is often not portable, so a vision screening can never achieve the same level of diagnosis as an eye exam at an office.

At our office, we have digital retinal images through an Optomap retinal camera. It allows us to capture awesome images of the retina of the eye. We also use an OCT (ocular coherence tomography), the equivalent to an ultrasound that measures the retinal layers. An OCT is an essential part to identify early signs of sight-threatening disease.

Reading the eye chart across the room is an effective evaluation for visual acuity and is generally enough to receive a screening pass. However, an in-person exam tests reading skills, the risk for double vision, a sinister eye disease in hiding like Glaucoma, or a subtle sign in the back of the eye that shows signs of diabetes. A vision screening will never identify these serious issues for eye health. Vision screenings are meant to educate people and parents about the importance of in-person eye exams with an eye doctor.

Wellness exams are preventative and needed regardless of displaying symptoms of a disorder.

In our area, we must educate friends and family that a higher level of care starts by visiting an optometrist in person.
