The threshold for light sensitivity is much higher in infants compared to adults. From birth, the pupils of an infant remain constricted to limit the amount of entering light. In regards to pupil dimensions, newborns' pupils grow from approximately 2.2 mm to an adult length of 3.3 mm. [ 2 ] A one-month-old infant can detect a light threshold ...
A later experiment with kittens raised in the dark and then placed on the visual cliff showed that depth perception was not innate in all species as the kittens would walk on either side of the visual cliff. After six days of being in the light, the kittens would avoid the deep side of the visual cliff (Rodkey, 2015).

Clothing may be worn, but the clothing should be placed over the light pad, and the light pad should still be in direct contact with the baby's skin. The light pad should never be placed on the baby's head. [11] The baby can sleep, eat, or be held while the light pad ...
