Abstract


611 children (297 boys and 314 girls) of a primary school were determined under 2 cyclogyl.
(1) Among 611 children, refractive error was 70.46% and emmetropia 29.54%.
(2) As to the distribution of refractive errors, 72.47 % were hyperopic and 27.53 % myopic Hyperopia was more common than myopia.
(3) Hyperopic refractive error was increased until 7 years of age. Since then it has been decreased 8.74% yearly.
Myopic refractive error has been increased 8.74% yearly since 8 years of age.
(4) The refractive errors were more frequent in women (37.81) than men (32-65%)
(5) Refractive errors were numerous around the age of 11. (24-77%).
(6) The degree of refractive errors varied, but in the great majority was less than 3 diopters.
(7) As to the type of astigmatism, 59.42% were with the rule and 39.94% were against the rule.
