Advice from a mountaineering medic of the silver age
before the glare begins to be felt.
A five per cent solution of cocaine dissolved in rose-water, and with a little boric acid added, acts like a charm in snow-ophthalmia. It is not easy, unless the right method is adopted, to introduce the fluid into the eye, for directly the lids are separated a gush of tears ensues and washes out all the lotion. The sufferer should be directed to lie down with the back of his head to the light and with the eyes closed; a few drops of the solution are then poured into the little depression which is above the inner angle of the eyelids by the side of the nose.
