What's medical optometry?

Medical optometry involves checking the concentration of light as it hits the eyeball and measuring the difference in concentration between the checked eye and the emmetropic eye. It provides a scientific prescription given based on examining the patient's eye, refractive state, eye position, adaptation, visual function, age, occupation and eyes habits, etc., involving the optometric degree, eye position, adaptation, binocular/monocular function, convergence function, binocular balance and dominant eye discrimination with the aim of maximizing the clarity and comfort of vision as well as attractiveness of available eye care including glasses. This can all be achieved through deep medical and optometric knowledge.
