Abstract

The prevalence of myopia has significantly increased over the past 50–60 years and is no longer limited to urban areas in East Asia. In the United States, approximately 148 million people (51% of the population) use visual correction aids, with 34 million wearing contact lenses. The incidence of myopia rises with age: 3% among children aged 5–7 years, 8% in those aged 8–10 years, 14% in ages 11–12 years, and up to 25% among adolescents aged 12–17 years. This study aims to determine the prevalence of refractive error (myopia) due to e-learning among students at SMK Negeri 1 Purwokerto. A quantitative survey method with a cross-sectional approach was used, involving questionnaires and direct visual acuity examinations. The study involved 26 respondents, with the majority being female (88.46%). The results showed that 4 students (15.38%) were diagnosed with refractive error (myopia) after engaging in e-learning. The number of students with visual acuity decline increased from 6 students (23.08%) to 10 students (38.46%) after the implementation of online learning. These findings suggest that e-learning, particularly with excessive gadget use, contributes to the rising incidence of myopia among students. This study highlights the potential link between prolonged screen time and visual health, underlining the need for preventative measures to reduce the adverse effects of digital learning on eye health.

Abstract

Hypermetropia, or farsightedness, is a condition where an individual struggles to see nearby objects clearly due to the eyeball's main axis being too short, causing light entering the eye to focus behind the retina. As a result, objects positioned close to the eye cannot be seen clearly by the affected person. The aim of this research is to understand the subjective refraction examination method to determine the lens prescription for both distance and near vision in individuals with presbyopia and hypermetropia refractive status. This study is a descriptive case study that describes the subjective refraction examination cases in presbyopic individuals with hypermetropia refractive status. The research sample was taken from Optik Boy Semarang during the period from October 1 to October 31, 2023, and included individuals with presbyopia and hypermetropia. The findings revealed that among the 58 total patients, 22 individuals (37.93%) had presbyopia with hypermetropia refractive status. Following the refractive examination of two patients (case studies), the prescribed eyeglass prescription was determined to be ODS. S+1.00 D 6/6 with Add S+2.00 and OD S+1.00 OS Plano 6/6 with Add S+3.00. The research concludes that prescribing eyeglasses for presbyopic individuals with hypermetropia refractive status involves correcting near vision by providing addition lenses. For distance vision correction, positive spherical lenses (S+) are prescribed based on the refractive examination results. The emphasis is on the patient's visual comfort without compromising the best monocular vision, assisting in clear vision for both distance and near activities.
