How to do subjective refraction?RefractionRefraction involves altering the wave direction while passing from one object towards the other. Also, several forms of errors may occur during the refraction process. These errors include; nearsightedness and farsightedness....
Retinoscopy (objective refraction) Retinoscopy basics The aim of retinoscopy is to obtain an objective refraction – that is, an estimation of the patient’s spectacle prescription using a process that does not require any decisions to be made by the patient. Retinoscopy also gives a good bench...

The lenticule is made in such a way that it refracts the returning light at a specific angle and magnifies the image. The strips are aligned so that all of the strips for a particular image are refracted to the same point. Because of the refraction and magnification, what you see is a...
This is called refraction. When light reaches a convex lens, the light rays bend toward the center: When light rays reach a concave lens, the light rays bend away from the center: The eye has multiple angulated surfaces that cause light to bend. These are: The interface between the air ...
