Abstract

Aim: Quality of vision in color blind while driving in different conditions. Main outcome measures: Driving quality in different visibility conditions. Methods: Observational study with 24 color blind cases and 15 age- sex- matched controls with normal colour vision. Inclusion criteria: Color blinds with BCVA >6/12. Exclusion criteria: Acquired color blindness cases. Without knowledge of colour vision status, the instructor tested all in driving school simulator under normal condition, in fog, night and during rain (Courtesy: Maruti driving school). Results: In normal condition & at night, both cases & controls had comparable results. But under poor visibility, color blinds had visibility up to 100m in high fog & 50 m in rain. Controls had difficulty in driving in a similar ambience. Conclusion: Color blindness does not hamper maneuverability and may prove useful in certain circumstances. Revision of driving guidelines is recommended to include 8% of men who are colour blind worldwide
