11. Static retinoscopy is a type of retinoscopy used in determining a patient's refractive error . 12. This can be treated with occlusion, and any refractive error can also be corrected. 13. The word " ametropia " can be used interchangeably with " refractive error ". 14. Examples of refractive error are myopia, hyperopia, and astigmatism. 15. When a refractive error is corrected with concave lenses. 16. On refraction, his refractive error was-7.25 Diopters in right eye and-8.00 /-0.25x15 in left eye. 17. A typical human eye without refractive error has a refractive power of approximately 60 diopters. 18. PRK is a laser treatment of the corneal surface for the correction of refractive errors . 19. People mostly begin to suffer from presbyopia, refractive error between the ages of 40 45 years. 20. Accommodative esotropia is a form of strabismus caused by refractive error in one or both eyes.
