چکیده
?Myopia is an error of refraction, due to elongation of the-yeball, and its conditions vary with its degree. When it does n?t exceed four or five dioptres it is of little disadvantage, excePt to those who wish to enter the public services, or whose 0ccupations require particularly good far vision ; but as the amount increases, it causes more and more damage to the 'gnt, until in its high degrees it becomes a very serious disease. ntants are almost always hypermetropic, and the higher &rades of myopia are reached in every instance by gradual svelopment through the lower, so that any case, however ^ght, may be on its way to the highest degree of the defect. *s therefore of the greatest importance that thoroughly CornPetent medical advice should be sought in every case of c?rnrnencing short sight, in order that the disease may be arrested if possible, or at any rate prevented from reaching the extrenie amount which would result if all prophylactic measures ere disregarded. The problem of defective eyesight can nder no conditions be properly dealt with merely by testing e refraction and prescribing spectacles, and there is no ember of a family whose future comfort and usefulness will ePend more on well-timed medical advice and hygienic treatment than the child who is developing myopia. .
