The Art and Science of Writing a Prescription by an Ophthalmologist
The clinical examination for a spectacle power lens is called refraction. All eye specialists are perfectionists besides being surgeons. But the science of refraction is also given as a clinical course to non-medical persons. It is called optometry and includes refraction and the making of spectacle glasses and their fitting into frames. The optometry course is of two or three years all over the world. Nobody, except an eye specialist or an optometrist, is authorised to test eyes though in the hard trade world of today every salesman claims to be an oculometrist. The oculometrist, however, always seeks the help of an ophthalmic surgeon when a problem involves more than eve testing. I would like to emphasise that there is no alternative treatment by way of drugs to substitute glasses. In all cases, glasses must be accepted as a tonic for the eyes.
