A long-sighted, or hypermetropic, eye is one which can focus light from distant objects, but not from near objects. These defects in focusing are remedied by wearing glasses with lenses so shaped as to counteract them. Short-sightedness is corrected by concave lenses and long-sightedness by convex lenses, as shown in diagrams above. Astigmatism is another defect in the focusing power of the eye.
Are we justified in concluding, then, that in the "good old times" of our great-grandmothers that idyllic time when women must have been at least free from the reproach that they, solely and unaided, were destroying the hopes of the race that myopic, hypermetropic and astigmatic eyes were not in existence? Such a conclusion would be manifestly unfair.
