First, let me say that I consider dyslexia to be poorly defined and often poorly diagnosed. By that I mean that I’ve found that children who struggle with reading (and often writing as well) often have problems with their visual skills that have gone undiagnosed. In particular, they often have binocular vision problems. That is, their eyes don’t work well as a team, even though both eyes have good vision individually (sometimes after correction with glasses) and even though they are capable of passing the rudimentary testing for binocularity that nearly all optometrists will administer.

But put those same children in front of a few pages of print and they either struggle initially, or they begin to struggle after a few lines, paragraphs, or pages, of print. They simply can’t maintain the effort to keep both eyes properly aligned and working together.

So is a child with poor vision skills dyslexic? Well, if they can’t read well, and have struggled with normal reading instruction, they’ll almost certainly be considered to have some sort of dyslexia. Unfortunately, the reading research community has gone down the route where they almost uniformly consider dyslexia to be an auditory problem, not a visual one. But if you fix the vision problem and a “dyslexic” child then easily learns to read, were they dyslexic? See the problem?

Anyway, if your real issue is one of poor vision skills, they here are other issues you might face:

You might have trouble catching a ball (because your eyes disagree on where the ball actually is.)
You might be considered somewhat clumsy, often bumping things or knocking them over unless you’re very careful (because binocular vision is essential to depth perception so you have trouble determining visually how far away an object is.)
You might get carsick easily (because the best way to avoid carsickness is to focus on the world outside the moving car, and you’ll have trouble focusing with poor binocularity.)
Ironically, you might naturally develop a skill that many people find difficult to acquire. That is the skill of translating our three-dimensional world to two-dimensional drawings, as architects, engineers and builders are required to do. This is because you have naturally acquired the ability to locate things, say your coffee cup handle, in your world without being able to rely upon the depth perception most of us rely upon. Instead, you’ll be continuously evaluating lines in the room, the line of your desk relative to the location of the cup, for example, or the lines of the napkin it sits upon. These all provide clues as to how far you have to reach for the cup handle. They’re not perfect clues, but in learning (naturally, without coaching, because no one’s told you that you lack depth perception) to use those clues, you’re also learning to translate 3-D to 2-D and back again which is what architects do all the time (sometimes after intensive training). And it is a fact that many dyslexics gravitate toward the field of architecture.
Try searching for “issues related to poor depth perception” and you might learn even more examples of what a poor reader (a dyslexic?) with a vision issue might face. Also search for “issues related to poor vision skills” as well. I haven’t done so, but you’ll likely find other suggestions as to things that many people now considered dyslexic will face. For example, one vision skill involves picking detail out of background, a visual perception skill. This sort of vision skill is also addressed by vision therapy.
I just realized that until now I hadn’t mentioned vision therapy. That’s a therapy offered by developmental optometrists to address not only poor binocular vision skills, but also other vision skill deficits. I found it to be the answer for many of the children I worked with over the years. Once their vision issues were addressed, teaching them to read became relatively easy to do. Before they were addressed, both student and I would often struggle to accomplish much.

Incidentally, there are some who consider vision therapy quackery. Someone claimed exactly that in response to one of my previous posts. They’re wrong, but no one will convince them of that, including the hundreds of thousands of parents who found it to be an answer to their child’s struggles. Vision therapy isn’t the answer for all reading problems, but the existence today of around a thousand vision therapy centers in the U.S. argues that they are probably providing something of value to parents with children who struggle with reading.

I hope you find this a useful comment.
