The eye may be designated as an end organ of the brain through which the latter discharges its visual function, thus explaining the disturbance of cerebral reflex centers by slight errors of refraction and consequent interference with various functional activities.
Twenty-five per cent. of all civilized people suffer from conditions dependent on ocular malfunction and clinically described as eyestrain. A large proportion of these cases is not reached because few physicians correctly diagnose the condition, the profession, as a whole, being poorly informed on this subject. If insomnia, nervousness, headache, indigestion and constipation may result from ocular defects, the physician should know this and so be able to prescribe the proper remedy.
Whenever our text-books emphasize more clearly, and our medical schools teach more explicitly, the pathogenesis of eyestrain, we may have recognized colleges for postgraduate work along these lines and laws confining the practice of opthalmology and refraction therapy
