[Optometric scale for pre-schools: method for determination of regional figures]

Children often show difficulties to identify optotypes in the picture scale. An experimental quantitative study with a sample of 384 randomly selected children was developed in order to identify pictures known by them and create suitable optotypes for a local reality. According to children's drawings, it was possible to realize how much the drawings were related to their daily lives. Considering the most meaningful drawings, we can mention: sun, human figure, house, cloud, tree, car, ball, star and heart. The most frequent figures were synthesized in order to make them more similar to the optotypes; the pictures were validated based on 95% confidence interval for the number of right answers: car (100%), house (98%), heart (98%), star (95%), ball (89%), flower (85%), sun (83%) and human figure (78%). In conclusion, those pictures belong to local culture.
