I'd like some advice on something I've recently noticed in my 29 month old's vision. {History: born at 32 weeks do to PTL, uneventful birth, 23 day NICU stay with 2 weeks on oxygen and 1 on caffeine, febrile seizure after his one year vaccines, and allergies} He has known the basic colors for months and can identify them by name or if you ask him to point at them. Normally he gets them right 95% of the time. Except red and blue, which is 50/50, this leads me to believe he is just guessing and might not be able to see the difference. The past few weeks I've really focused on showing him these colors and talking about different objects that are these colors. Nothing has changed. His vision seems to be normal otherwise. Would this raise any flags for you? Should I set up an appointment for this? There is probably little they can do if he is truly color blind, however it makes me nervous that something else could be wrong.


It would be worth talking to your doctor, perhaps at a check-up or sooner if you are in for something, as he or she has a simple screening test for this. Unfortunately, I can say from my husband's experience with color blindness that there isn't anything you can do about it. If it is that, I believe it is generally thought to be inherited and not related to any other developmental issues.
In my husband's case, during preschool years, there was some confusion for a while as to whether he was having trouble learning his colors, but they eventually figured out that it's color-blindness.
