Because I’ve written in the past about my son’s colour blindness, I do get a lot of search engine queries about it at this blog. Questions relating to whether or not their child is colour blind. I’ve been meaning to share a few links that have helped me for a while now, and spending time at a parenting forum today, talking to another mum who was wanting to know, has prompted me to write this now.
Obviously, once I had reason to believe my son was colour blind, we had an opthalmologist confirm it (he had an appointment in a month’s time anyway, so we just waited until then to confim what we already by now knew). An optometrist would also suffice, we just went to an opthalmologist because he sees one regularly for other vision problems anyway.
You can always check if a child knows their colours by showing each colour separately. My son, although colour blind, can recognise every colour most of the time if they are not next to another colour. Trying to distinguish colours that are side by side is where the confusion sets in. So, once you’ve had a look at how your child handles separate colours, put some together and see how they go. My son was incredibly frustrated when I tried him with this!
There’s also some good tests you can do on the internet as you’re waiting for an optometrist’s appointment:
There were two other good tests I found when I was checking my son out, and frustratingly, I can’t find them now! If/when I do, I’ll edit them into this blog post for you. If your child appears colour blind from one test, it’s natural to want to try a few other tests as well. Please, don’t ever hand over money for online colour blindness tests! There are plenty of free ones that will give you the answers. If you’re going to spend any money on this, it should be at the optometrist.
Here’s a tool that has helped me to familiarise myself with my son’s colour blindness: a colour filter. I used this when I created this blog post, showing how non-ripe bananas look to my son.
Note: if your child has colour blindness, both pictures will look identical to them.
I had a quick play with it just now, to show you how I look to everyone else (left) and how I look to my son (right)
Seeing how my son views people had led me to a theory about why he loves zombies so much. I decided to put a Plants vs Zombies character through the colour filter, and as you can see, there is really very little difference!
As I mentioned in my first post about his colour blindness, his drawings were a dead giveaway to his teacher! Don’t they look like zombies too?
There are other things my son’s colour blindness affects, so if you’re not sure if your child is colour blind, see if any of these sound familiar:
- can’t understand why he can’t eat a green banana no matter how much you explain it to him. (They both look yellow if you are colour blind)
- can’t make out red trees from green in Autumn
- struggles to make out colours on a map.
I also came across this link which will make any computer games-mad colour blind child happy:
I hope this is helpful to those who are looking! If you have any more resources you have found helpful or might help someone else relating to colour blindness, please feel welcome to share them in the comments below.
