Eyesight At Birth

At birth no infant can see. Professor Preyer, who has carefully worked on a single subject (a boy of his own), considera that although sensibility to light exists from tha moment of birth, yet this sensibility is more alive to the sense of feeling than to that of sight. The infan from the first closed its eyes when ex posed to a strong light. With regar( to actual sight, as denoted by the fix ing of the eyes on objects, Preyer says that up to the tenth day h8 noticed no movernents indicating that the child fixed its eyes on an object He seemed only to look at objects before him up to that time. Other authorities assent that in this latter respect infants differ greatly. This much, however, is clear, that it usually requires between two and three weeks for the sense of sight to come into full operation.
