DS might be colour blind

[SandandSky]

Just that really - Nursery and the Health visitor have flagged it (and now listening to what they’ve said it makes sense with a few of his behaviours) but no one has really offered any guidance from here? Even when asked.

Considered going to the optician but looking it up, I’m not sure they can test him until he’s older?

Anyone been there that can offer some advice, it would be hugely appreciated.

How old is he?
about 1 in 10 boys have a colour deficiency.

He’s just turned 3. He can’t really recognise any colours consistently apart from Pink/ Red and he has to smell everything before he will eat it. He puts a lot of non food items in his mouth.

They can test. It's not life threatening but worth flagging to school.

My ds is colour blind, didn't realise till he was 7, so took him to the optician.

They had those dotty circles with numbers inside, but they also had some shapes instead of numbers for younger kids.

The main ways it impacts ds is football training (orange cones on green grass are camouflaged to him), and ive been warned that when he goes to secondary to let his geography teachers know as maps can have shades of browns, greens and some bits of red which will all blend into each other.

My partner is colour blind and was diagnosed at 4. He was tested due to family history - maternal grandfather was colourblind so he had a 50% chance of being colour blind.

It is a spectrum and how severely it impacts you depends on how much of the colour definition you have lost. My partner doesn't have any red/green differentiation and slightly reduced blue/yellow. It causes shifts in the colour spectrum so it's not restricted to red/green. My partner can't see the difference between red and brown nor blue and purple. He can't see colour changes so struggles cooking meat it always looks pink to him so we bought a meat thermometer. He also can't see if meat has turned green.
He can't see pink at all. He once put on my black socks with pink hearts on thinking they were his as he couldn't see the pink hearts to him they just looked black. I could lost a dozen more amusing stories linked to his colour vision!
You can get glasses and there are add ons to add a filter to your computer. My partner uses this at work as overlaying red and green images is common in science.
I would say most weeks he his colourblindness comes up but its not something that negatively impacts his life it's just something that walks alongside him.

Red green colourblindness is hereditary. It's on the X chromosome Girls are XX and would need to colour blind X's to be colourblind. Boys are XY so only need to inherit one colour blind X to be colour blind. They get this from their mother. If the mums father was colourblind they would have one X and one Colour blind X. When they have sons it's 50:50 which X they get.

There are tests that can be done on children. There are the traditional what number do you see in the dots tests that can be done on older children and adults but they also have variants for younger children where they are looking for shapes in the dots instead.
