“Night Blindness.”

There is a defect of eyesight common among the natives of India known as “ratandhi lit, “night blindness. ” Persons affected with this have either ordinary powers of vision by daylight or else powers so little less affected than ordinary as to feel no little inconvenience, so that usually no defect js. noticeable; while in feeble twilight their sight fails in the most extraordinary way, and in the dusk they become (in bad cases) practically, blind. Of course there are all degrees of this

affection, but the strongly marked cases alone are likely to attract attention. By medical men in India this affection is said to occur most among men living pn - a low diet (chiefly of cereals), and the palliative treatment is * to prescribe a meat diet.
