1,350 schoolchildren, ages 11 and 14, from Palma de Mallorca, were explored looking for colour vision defects. The medical examination was performed through Ishihara tables (numbers or letters). There was not anomaloscopy to confirm the first results. We compare our prevalence with other known prevalence from Europe. Different outcomes (learning disability, effect on employment) are discussed.
