Refraction Test
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
The 'refraction-test' typically refers to a diagnostic procedure used in optometry and ophthalmology to measure an individual's refractive error. It helps determine the appropriate prescription for glasses or contact lenses by assessing how light is bent as it passes through the eye. The test involves presenting various lenses or using automated equipment to evaluate visual clarity and identify issues such as myopia, hyperopia, astigmatism, or presbyopia.
