Hi, all!
I am sure I will keep learning, but just a little update after I did some reading yesterday. This is a big deal in our lives right now, but don’t feel bad if you’re not interested. I’m writing about it both to inform those who want to know and to organize my personal thoughts about what’s happening with Asher.
Just like any medical condition, names identify the different visual conditions that Asher is dealing with. Asher has:
-Hyperopia (farsightedness)
-astigmatism (misshapen eyeball or lens or cornea or something)
-Strabismus (an eye that occasionally crosses in — though I think I can sometimes see it in pictures, it’s not really noticeable to me)
-Amblyopia (the condition I’ve explained before that occurs in small children whose eyes have different strengths that causes one eye to start going blind, also known as “Lazy Eye.”)
The good thing is that all four of these conditions are incredibly common. Having them is not as common as not having them, but whatever. Another really good thing is that the Hyperopia and astigmatism are easily corrected with the correct glasses and/or contact lenses. And, as I’ve mentioned before his age will help drastically with the treatment of both his Strabismus and Amblyopia. While his treatment is extremely important right now, we are very hopeful that in a few years both of these conditions will no longer be an issue for him.
So that’s what is going on. His Hyperopia is pretty bad, I guess. Hyperopia/farsightedness is caused by an eye that is too small. Knowing that it is caused by a physical development helps me understand why it is hereditary. I know that people with poor vision are encouraged to get their children’s eyes checked at a very young age (though it’s good for ALL little children to get their eyes checked while they’re young – !!!) Hyperopia occurs when a person’s eye is too small or when his lens or cornea is too flat or something like that. When any of these things happens, light travels incorrectly into the eye and does not meet at the correct focal point, causing images to be blurry. Asher’s doctor said that his eyes can change until he is about 7 years old, which is about the age that I keep reading is when a person’s eyes are done with the very crucial developments (maybe all the developments and growth? I’m not sure yet). So when we found out yesterday that Asher’s vision has gotten worse, it could be that his actual eyeball changed. There is a chance that the eye doctor didn’t get the prescription right to begin with, since he is so young and everything, but we think it’s more likely that his eye ball changed. He took to his glasses extremely easily (after about 2 days of being suicidal) and did exceptionally well with them until the last several weeks when we started noticing the weird things that I mentioned in my post yesterday. Come to think of it, he also outgrew a lot of clothes in the last 2-ish months… Hmmm…
So anyway, there are some of my thoughts about his prescription change. I know it’s normal for a small child’s vision to change pretty quickly, and from what I have read I think that is because a little kid is constantly growing and changing.
Here is a visual simulator that shows what a person with Hyperopia will see without glasses. Asher’s eyes are +4.5 and +7, so slide the little bar to those levels and see (or don’t see) what happens! It’s pretty crazy! If you hover over the top where it says “refractive errors” a little drop down list will appear and you can also see how the astigmatism affects his vision. He is currently at -1.0 in each eye with the astigmatism. Anyway, here is the link:

(I don’t know why it linked that last statement too, but it does it each time I try to fix it and I don’t feel like messing with it. Just know that I know it happened and then move on.)
And here is a video of Asher playing and watching TV yesterday to show how he has started using the corners of his glasses to focus on things. The doctor says he has found out how to create his own “pinhole” where the power of the glasses is intensified in the corners to help him see, since the prescription is now too weak. I guess it’s the same way that people learn to use bi/trifocals – their eyes just learn where to look to see properly. I don’t know if he’s using different spots for different distances, but he is definitely doing this for looking at things both far and near. Oh, before I post the video I wanted to mention that I read that people with severe Hyperopia don’t only have a hard time focusing on things close up. I guess people with Myopia (nearsightedness) often see perfectly fine up close, but lack the ability to see far, whereas people with Hyperopia like Asher often see blurry images of things both near and far, though it’s common to think they only struggle with what is near. Back to the video: Note that the cars I’m trying to get him to look at are a little bit to the side of him. You can see that when he looks at them he looks out of the corner of his eye and you can see him sometimes move his head very slightly to get a better focus. Then when the video changes and he is watching TV you can see that, though he is sitting directly in front of the TV (but across the room), he turns his head sideways and looks through the corners of his lenses.
I’m anxious to see how he does with his new lenses!
