WebWhen a light ray enters from a denser to a rarer medium, it bends away from the normal, leading to the angle of refraction is greater than the angle of incidence. When the angle of incidence is smaller, both reflection and refraction occur and most of … WebSubjective refraction is can be used to fine tune retinoscopy or auto-refraction measurements. Subjective refraction needs the patient to give feedback by telling the examiner which lens gives the clearest vision. You may know this as the part of the exam where the ophthalmologist asks “which is better, one or two.”
