What My Patients Taught Me About Vision 

When I first started seeing family eye care patients at Anderson Family Vision Care, I assumed that most vision problems would show up in the standard tests. However, the longer I saw patients, the more I found that there were many other vision-related conditions that people were struggling with that required more specialized testing and treatment.

Most eye tests are about looking at something still and far away. You sit in a chair, look at letters on a wall, and read them out loud. 

But think about what you actually do with your eyes all day, every day.

You’re reading a book, then glancing up at someone talking. You’re switching from your computer screen to your notes dozens of times an hour. You’re following lines of text, keeping your place, moving from word to word. You’re catching a ball, driving in traffic, cooking while checking a recipe. Your eyes are in constant motion, constantly adjusting, constantly working together.

I remember there was a point when I started seeing kids who could see the eye chart, but fell apart doing everyday tasks. One lost her place every few sentences while reading. Another couldn’t copy notes from the board without headaches. A third avoided reading because it was exhausting.

Their parents were baffled. “But the doctor said her vision was perfect!” And technically it was—at least the part we usually test for. But nobody had checked whether their eyes could do all the things eyes need to do in real life. Nobody did anything wrong; they just weren’t looking at how people were using their eyes.

One teenager I saw could see the eye chart, but struggled with homework taking much longer than it should. His eyes weren’t working together properly when he read, so his brain was working overtime to make sense of what he saw.

Some patients had had head injuries—sometimes major, sometimes seemingly minor concussions. They’d been medically cleared, but months later, they still struggled. Reading made them dizzy. Bright lights bothered them. Busy places, like grocery stores, felt overwhelming. A head injury can throw off how the eyes work together, even when the eyes themselves are perfectly healthy.

Vision is far more complex than whether you can see letters clearly on a wall. If someone’s struggling with reading, learning, or persistent headaches—or still having trouble after a head injury—and everything else checks out, it’s worth looking at how their vision actually functions in real life. Not just whether they can see clearly, but whether their eyes can work together the way daily life demands.

Sometimes the problem isn’t the eyes themselves. It’s everything those eyes are supposed to do together.

Due to the need for this type of care, we at Anderson Family Vision Care created GRAND Vision Development Institute to focus specifically on diagnosing and treating vision problems that affect our daily lives beyond those that require glasses, contacts, or surgery. At GRAND, we work with many optometrists and other healthcare professionals to provide this level of care.
