“May all be happy, may all be healed, may all be at peace and may no one ever suffer."
Eye refraction is the process by which the eye's ability to refract or bend light is measured, typically to determine the appropriate prescription for corrective lenses such as glasses or contact lenses. The goal of eye refraction is to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
During an eye refraction test, an eye doctor or optometrist will use a series of lenses and a device called a phoropter to measure how the eye refracts light. The patient will be asked to look through the phoropter and indicate which lens provides the clearest, sharpest image. The doctor will then use this information to determine the patient's prescription for corrective lenses.
Eye refraction tests are typically part of a comprehensive eye exam, which may also include tests for visual acuity, color vision, depth perception, and eye movement. These tests can help diagnose and monitor various eye conditions, such as cataracts, glaucoma, macular degeneration, and diabetic retinopathy.
It is important for individuals to have regular eye exams, including refraction tests, to maintain good eye health and ensure that any vision problems are detected and treated promptly.
