Brief Summary
Myopia, also known as short-sightedness or near-sightedness, is a prevalent condition that typically emerges during childhood and early adulthood. It occurs when the eye elongates excessively, causing images of distant objects to focus in front of the retina, leading to blurred distance vision. The number of people with myopia is increasing every year, reaching half of the world's population by 2050. The global potential productivity loss due to uncorrected refractive errors was $244 billion in 2015. Due to the strong association between high myopia and pathological changes in the choroid, retina, and sclera, leading to irreversible vision loss, and the fact that correcting the refractive error does not halt the progression of pathology, the prevention of myopia, especially high myopia, has emerged as a crucial international public health concern. In ocular examinations of children under noncycloplegic conditions, the influence of accommodation cannot be disregarded. Cycloplegic refraction is widely regarded as the gold standard in epidemiological assessment of refractive errors in pediatric populations. Moreover, due to children's decreased cooperation and unreliable responses, subjective refraction tests are less valued, and objective tests under cycloplegia are preferred. The portable vision screener 2WIN-S is a binocular tool that detects various ocular abnormalities and measures the refraction of both eyes. Along with measuring phorias/tropias in prismatic diopters and objective refraction in the range of -15D to +15D, 2WIN-S also captures additional features. This study employed the cycloplegic condition to measurements using 2WIN-S, ARK-1 and subjective testing, we wanted to test the reliability and accuracy of 2WIN-S.
