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.

Abstract

Accommodation insufficiency is an accommodation disorder characterized by a lower accommodation amplitude than the minimum limit of the Hofstetter formula. Symptoms of accommodation are impaired near vision, asthenopia (eye fatigue), blur, headache, and visual discomfort. This study aims to determine the prevalence of accommodation insufficiency in FKIK UKRIDA students class of 2023.  This study used descriptive quantitative research method and cross sectional research design with 150 respondents. Each subject was only observed once at the same time using the RAF Rule as a measuring instrument. Data collection was carried out from September to November.  The prevalence of accommodation insufficiency in FKIK UKRIDA Batch 2023 students amounted to 2 people (1.3%) in both eyes, 6 people (4%) in the left eye, and 2 people (1.3%) in the right eye.  Accommodation disorders can be influenced by age and refraction. The prevalence of accommodation insufficiency in FKIK UKRIDA students of 2023 is 1.3%. The highest number who experienced accommodation insufficiency was in the left eye, which was 4%. It is recommended that people pay more attention to their eye health by conducting routine eye examinations every 6 months-1 year.
