For Nearsightedness
For nearsightedness, close the eyes and pass the fingers, very gently, several times across them outward, from the canthus, or corner next the nose, towards the temple. This tends slightly to flatten the corner and lens of the eye, and thus to lengthen or extend the angle of vision. The operation should be repeated several times a day, or at least always after making one’s toilet, until shortsightedness is nearly or completely removed. For long sight, loss of sight by age, weak sight, and generally for all those defects which require the use of magnifying glasses, gently pass the finger, or napkin, from the outer angle or corner of the eyes inward, above and below the eyeball, towards the nose. This tends slightly to “round up” the eyes, and thus to preserve or to restore the sight. It should be done every time the eyes are washed, or oftener.
