Eyesight and Electricity.
Hitherto it has -been supposed that electric light is more injurious to the eyesight than any other artificial Ugh*,, but Russian oculists who have feeeu closely studying the subject now maintain that, on the contrary, it is less injurious than the light either of gas or candles or any other material. As a reason for this statement they point out that diseases of the eyes are in proportion to the number of times the eyes blink or wink when subjected to artrficial light, and that after numerous tests had been made, it was found that the eyes blink about seven times a minute when exposed to candle light, about three times when exposed to gas, twice when exposed to the sun, and only once when exposed to electric light.
