I took Trevor for his first eye exam two days ago, and they gave him a color blindness test with the types of color plates as seen in the attached photo. During this eye exam, it was determined that he is farsighted and also has some sort of focusing ability issue, so he has been scheduled to start vision therapy next week. I'm sure to find out more after that first appointment, as right now I can't say that I know much of what's going on with his eyes other than being farsighted.
However, for the color blindness test, which was given to him twice--once before eye dilation and then again after dilation--he failed it the first time but did slightly better after his eyes were dilated. After the first test, the doctor said he was color blind with red and green colors because he could not make out, for example, the number of 6 and 8 in the attached picture (the bottom two circles). He failed to see the numbers, shapes, or lines in five different similarly colored plates during this test. Yet after his eyes were dilated an hour later, he was able to make out some of the numbers, so then the doctor said he wasn't sure...which is why, among other issues, he's referred Trevor to vision therapy, and then doing a re-evaluation of the eye exam in four months with a pediatric opthamologist scheduled to work with him.
I'm having a hard time believing he's color blind. He knows his colors and can pick out whatever color you ask him to from a box of jumbled up crayons or markers. He colors pictures in "rainbows" because he likes all the combinations. Basically, I NEVER in my wildest thoughts and concerns about him would have wondered, is he color blind?
I was wearing a solid light forest green t-shirt yesterday, so I asked him what color my shirt was. He said it was green. I held up a red snack bag of Apple Straws and asked what color the bag was and he said, "It's red." Then I took a real apple that was mostly red and held it so he could see it from the top at the stem, where it had greenish-yellow streaks around the core and stem and asked him what colors he saw. He looked at me like I was crazy and said, "Green and red. Why are you asking me what colors I see?" (the doctor and I hadn't told him he was color blind, and he also wouldn't even know what that meant if we did tell him, hence his confusion).
This morning, I pulled out a "Clifford the Big Red Dog" book and had him look at the cover because there was a leaf pile pictured with the colors red, brown, orange and yellow all mixed together. I showed him the book cover and asked what color leaves were in that pile. He said they're red, brown, orange and yellow almost immediately.
So if he IS color blind, then is it possible for it to not be very severe? I looked it up yesterday and color blindness doesn't seem to have much of a spectrum of severity--either a person is or is not. I'm thinking maybe he just has a problem distinguishing between contrast and saturation of colors, maybe? I mean, when I look at the color plates in the attached picture, it's even a bit difficult for me to find the numbers in the bottom two plates. But I don't think he failed to see the numbers because he couldn't see the colors.
Just wondering if there's anyone out there who is color blind, or who knows more than I do about this, and could give me a little more information.
