Refraction of the eye – what is refraction and what are the main refractive disorders of the eye?
Refraction of the eye, to put it simply, is the refraction of light by which a person is able to see an image clearly. It occurs when light entering the eye becomes focused so that it reaches the retina. This phenomenon makes it possible to see observed objects clearly, provided that the patient does not experience refractive disorders, i.e. a defect in vision. What are refractive errors and how are they corrected?
