How to Preserve Eyesight.

Avoid all sudden changes between light and darkness. Never begin to read, write, or sew for several minutes after coming from darkness to a bright light. Never read by twilight or moonlight, or on dark, cloudy days. Wheh reading it is best to let the h'ght fall from above obliquely over the left shoulder. Do not use the eyesight by light so scant that it requires an .effort to discriminate. The moment you are instinctively prompted to rub your eyes, that moment stop using them. If the eyelids are glued ’together on waking up do not forcibly open them, but apply saliva with the huger. It is the speediest dilutent in the world; then wash your eyes and face in warm water.
