      Yeah, I have Deuteranopia. It doesn’t mean I can’t see red or green, or differentiate between them, but it means I can’t see certain shades of either colour. So that meant I couldn’t be a pilot because of landing lights.

      You know those tests at the opticians where there’s hundreds of colour dots, and you read a number from them? I always get those wrong.
