Most people with nystagmus have poor contrast sensitivity too. That means it's hard or impossible for us to read green text on a blue background for instance. We like strong contrasts like black on white, yellow on black, etc. We like the brightness turned up on our phone and laptop screens. We struggle to see things in shadow. Generally speaking, poor contrast sensitivity is yet another subtle reason why we don't see as well as people who don't have nystagmus.
Nystagmus itself does not, as far as I know, affect colour vision. So, most children with nystagmus can see colours just like most other people. However, there are of course always some caveats. Some of the eye conditions associated with nystagmus may affect our ability to see colour. And our ability to see colours at a distance is likely to be affected too.
The CVI Society is entirely run by people giving up their spare time to share information and support others.
If you can provide funds for the things we cannot get for free then you can help us to help others.
