    never directly into the mirror, as that would soon irritate and compel him to close his eye. In this way the patient avoids the strain of looking into the bright reflexed light, and at the same time the macular region is refracted (see Fig. 32). It is customary to cover the patient's other eye while its fellow is being refracted; for obvious reasons this is specially important in cases of squint. The axonometer placed before the eye being examined is a decided advantage in any instance (see p. 52 and Fig. 44).
