RESULTS OF EYESTRAIN

SICK HEADACHES MOST COMMON Neuralgia and sick headaches are the most common result of eyestrain. Another common effect of errors of sight is giddiness, and people are very prone to think: of it:as-being caused by the heart or the kidneys, or by gastric trouble, or something of the kind (and, indeed, it often is), but the most common cause- in people about middle life—eye defect—is often slight and, therefore, unsuspected. Nausea and vomiting are often due to eyestrain, too. the commonest form being the sick headache that follows after being on . the water, exposed to brilliant sunshine, on a bright day. The less common manifestations are where the energy - runs to waste and the nervous system ibecomes exhausted. LOSS OF NERVOUS ENERGY Eyestrain taps the' nerves and lets your energy drip away uselessly. It may cause such surprising manifestations as attacks of hysteria, or even seizures, that have been mistaken for epilepsy.. In degrees still more protounced, it may lead to melancholia. If, therefore, you find that you or your friends need, to screw up the eyes, or I lace the head on one side, in order to read or to see some distant object, a capable medical specialist in eyes should l e consulted; and if there is a slight redness and swelling of the margins of the eyelids, particularly the upper eyelid—or if, in a patient under 40 years of age, a white line is seen rimming the iris, and especially if one eye only i i ', affected —eyestrain from an eye defect of some kind is almost certain to tie present.
