  1. CBQ-oL Colour Blindness Quality of Life scale, SF-36 MH mental health subscale of the MOS 36-Item Short Form Health Survey, PMI Positive Mindset Index
  2. Comparisons between CB participants and NV controls are made using matched t-tests. For men there were 11 age-matched pairings from 16 CB participants and 18 NV controls, and for women there were 5 age-matched pairings from 5 CB participants and 20 NV controls. Comparisons between CB and NCV are made using matched t-tests. The 30 age-matched pairings were from 46 CB and 199 control participants
