Abstract

Color vision deficiency is the inability of the eye to distinguish colors, this can occur both congenitally and acquired. Color vision deficiency can affect a person's quality of life performance and the selection of advanced study programs in children. This study aims to determine the prevalence and characteristics of color vision deficiency in detail in elementary school-age children. This study used a total sampling technique with a cross sectional method with 366 respondents. Data collection was carried out from September to October. In this study, 5.2% (10 people) of respondents experienced color vision deficiency. As many as 2.2% (8 people) of respondents had partial color vision deficiency and 0.5% (2 people) of respondents had color blindness (monochromat). Of the 195 male respondents, 4.6% of them suffered from color vision deficiency while of the 171 female respondents, 0.6% of them suffered from color vision deficiency. Color vision is related to cone cell photoreceptors. Each type of cone cell plays a role in color vision. The prevalence of students with color vision deficiency is 2.7%. In this study it was found that students had partial and total color vision deficiency (monochromat). The most common type of red-green color vision deficiency. The highest prevalence is in male students. It is recommended to the government and schools to carry out a complete eye examination including a color vision examination so that it can support the learning process and the selection of advanced study programs according to the child's condition.

Abstract

Myopia is an eye disorder in which parallel rays coming from an infinite distance are refracted in front of the retina. Astigmatism is an optical condition of the eye, in which parallel rays are not refracted at a single focal point, so that the focus is unclear, vision is blurred and often dizzy. Anisometropia is a difference in refractive error between the two eyes of 1-2 Diopters (D) in one or more meridians. This can cause aniseikonia, namely a difference in shadow both in shape and size that causes difficulty in fusion. Hypermetropia / Hyperopia / farsightedness is a condition of not being able to see close objects clearly, this condition is the opposite of farsightedness (myopia). The symptoms of hypermetropia are similar to presbyopia in the elderly. Research objective is to educate students about visual health. Method is data collection was conducted through anamnesis, visual acuity examination using refraction instruments and distributing questionnaires to students of the Nafiri Sion Fajar Kemuliaan Christian Church aged 12-22 years, totaling 62 people, then diagnosed with refractive disorders. There is a relationship between refractive disorders and students' reading behavior.
