Is 20/20 Vision Perfect Eyesight? Not Necessarily – Here’s What You Should Know About Eye Health

You might think your eyesight is perfect because you have 20/20 vision, but there are other considerations that aren’t related to refractive error. Here’s what you should know about possible undiagnosed eye conditions. OptiExpress provides comprehensive eye exams, contact lens fittings, a gallery of designer frames, and a one-hour onsite lab.

Numerous vision issues aren’t caused by nearsightedness, farsightedness, or astigmatism. Unfortunately, many people don’t realize they have a vision issue, and this lack of attention can lead to problems in the long-term.

Vision Conditions in Children

Certain vision problems are fairly obvious – lazy eyes and crossed eyes are two of the most noticeable conditions – but numerous issues are easily missed. Vision problems in very young children are often undiagnosed for a variety of reasons. These reasons the inability of small children to articulate what they’re seeing and feeling, and the possibility that they don’t know that there’s anything wrong because the symptoms have always been there.

Sometimes, vision issues in children are interpreted as behavioral problems. Challenges with concentration, short attention span, lack of depth perception, and physical complaints like headaches and neck pain are often misinterpreted. Some children with undiagnosed vision issues might be thought to have learning disabilities, when the problem is really their ability to see.

Binocular Vision and How it Affects Your Sight

Our eyes must function as a pair in order to perform optimally. Each eye captures an image at a somewhat different angle because of the way both eyes are set from each other. It’s the combination of images that achieves a three-dimensional picture of the environment, giving us special awareness and depth perception. Both eyes’ ability to work together is called binocular vision. Problems with binocular vision can be due to the following issues:

  • Amblyopia: This is the medical term for “lazy eye,” a condition where one eye’s acuity diminishes because the brain begins to favor the image capture of the other eye.

  • Convergence Excess: This is when the eyes involuntarily turn inwards too much when focusing on close objects.

  • Convergence Insufficiency: This is when the eyes lack the ability to turn inward to focus on close objects.

  • Divergence Excess: This is when they eyes turn outward to excess when focusing on distant objects.

  • Divergence Insufficiency: This is when the eyes are incapable of adequately turning outward when focusing on distant objects.

  • Strabismus: This is when the eyes do not align with each other, and instead turn outward or inward. Also commonly known as crossed eyes.

These conditions can be successfully treated with corrective eyewear, with special therapies, or surgically, depending upon severity.

Regular, comprehensive eye examinations are essential for ensuring optimal vision. Having your eyes checked by a qualified optometrist can help you identify these and other potential concerns with your eyesight and overall health. Eye exams are particularly important for school-aged children, because the standard test with the eye exam chart doesn’t always catch binocular dysfunction or other vision issues.
