Our bodies are capable of adapting to changes in the eyes. According to Dr. Wernick FCOVD, the human body is really resilient and the behavior of someone could change without them even knowing it in response to an eye problem. A person might have a dominant eye and the other one has a problem, whether it's a lazy eye, an eye turnor a damaged eye, they have one eye that works much better than the other. One behavioral change that can be seen is that people will lead with one eye and turn their heads when they talk so they can look with their dominant eye in the middle of their head. Their reason for doing this is that it expands their usable field, so what they're looking at gets preference, and everything else opens up their field. That's one adaptation, but there are many other examples of how we adapt to changing visual performance. For example Dr. Wernick will often notice children that change behavior without realizing it is vision related, they may begin to hold reading material closer, squint, close one eye when reading, tilt their head while reading, or become upset about doing near vision tasks such as reading.

There's more to it than meets the eye

It isn't always what it seems, both for the person experiencing it and for those observing it.

You can't tell from the outside whether someone has vision problems. In reality, it's not uncommon for an individual who is having trouble to not realize that something is wrong and that they need to mention it. As an example, a child with double vision may assume that it's completely normal.

Once, a parent contacted Dr. Wernick after a lecture and said that when talking to her kids about the lecture, her son casually mentioned that he sometimes wasn't sure which football to catch. It turned out that he had been intermittently experiencing double vision and assuming it was normal, he had not mentioned it.

Including adults as well

Children aren't the only ones who experience this. An elderly person with vision problems might simply write it off as a natural issue brought on by aging when in fact it is something completely different that can be treated.

It is possible for younger adults to do something similar, but in a different manner. A minor issue could be dismissed as nothing to worry about, and they might not seek treatment. If said minor issue is an indication of something more serious, this could end up becoming a bigger problem down the line. Treating something early is always the best course of action.
