The development of digital technology has had a significant impact on the health sector, including eye examination services. This study discusses the development and implementation of a Digital Optoscope-based Eye Diagnostic application designed using a web platform (HTML). This application provides two main features: visual acuity testing and astigmatism testing, which can be accessed independently by users through digital devices such as laptops, tablets, or mobile phones. Users only need to follow the visual instructions presented interactively on the screen, then perform the test according to the procedure. The testing method is carried out by displaying font size settings according to the Snellen chart standard and radial astigmatism patterns. The results of each test session are automatically recorded and can be saved for further analysis. In addition, users can perform repeated tests to improve the accuracy of self-diagnosis, and the system will provide lens type recommendations based on the measurement results obtained. The trial results show that this application is able to provide convenience, efficiency, and initial accuracy in the process of examining vision disorders. This is very useful, especially for people in remote areas or with limited access to professional eye health services. Thus, the Digital Optoscope-based Eye Diagnostic application has the potential to be an innovative solution for the early digital detection of vision disorders. This study recommends further development, particularly in clinical validation, testing on a wider sample size, and integration with electronic medical record systems to enhance its benefits in comprehensive public health services. Furthermore, collaboration with medical professionals is crucial to ensure diagnostic accuracy. With this approach, the app is expected to become a reliable tool for continuous eye health monitoring.

Presbyopia is called Also eye old or vision old that is condition Where ray come parallel No can refracted appropriate on the retina, but No on One focus point , can in front of or behind the retina. Hypermetropia known Also with nearsighted near , where ray parallel refracted behind the retina, as a result object that is located Far from the eyeball No will looks clear in vision sufferer . Concept base For to overcome presbyopia sufferers with refractive status hypermetropia is with give glasses For tool help his vision . Purpose study This is For know method determine size glasses on presbyopia sufferers with refractive status hypermetropia in optics Agus . Type study This is studies case with approach descriptive . Population in study This is overall sufferer abnormality refraction visiting​ to optic Agus on 01-29 February 2024 . The method of data collection used is interview And observation . Total sufferers abnormality refraction visiting​ to optics Agus as many as 66 patients with details of 5 patients emmetropia , 27 patients with myopia refraction status , 28 patients with refraction status hypermetropia and 6 people with refractive status astigmatism . And in study This obtained case vision Far And near run away , after corrected Then given S+1.00 lens ADD +200 for eye right And left . Based on results study This can concluded on presbyopia sufferers with hypermetropia status can handled with use bifocal or multifocal glasses .

Astigmatism is a refractive disorder caused by uneven curvature of the cornea or lens, causing light not to focus on the retina. This study aims to measure the prevalence of astigmatism among students at Ma Chung University and identify the relationship between the duration and position of gadget use with astigmatism. The study method used a cross-sectional design involving 125 students aged 17–24 years. Data were collected through questionnaires and eye examinations using a Snellen chart and keratometer. The results showed that 38.4% of students had astigmatism. Most students (96.8%) used gadgets for more than 2 hours a day, and 91.2% used gadgets in a lying position. Using gadgets in this position and for long durations increases the risk of astigmatism. The conclusion of this study is that astigmatism is a significant problem among students. Implementation of the 20-20-20 rule and increasing outdoor activities are recommended for prevention. Routine eye examinations are also needed so that disorders can be detected and treated early.

This study aims to determine the prevalence of refractive errors in children with Down Syndrome in eye examination activities carried out during Down Syndrome Awareness Month 2023 by the East Java Association of Parents of Children with Down Syndrome (PIK POTADS). A total of 30 children with Down Syndrome underwent eye examinations, and the results showed that 18 children (72%) had myopia, 7 children (28%) had astigmatism, and 5 children were indicated to require further referral to a pediatric ophthalmologist. These results indicate that children with Down Syndrome have a high risk of experiencing refractive errors, so regular eye examinations and medical follow-up are needed.
