QUESTION:
Research and the university of Pennsylvania and the childrens hospital of Philadelphia indicates that children who sleep in a dimly lighted room until age 2 may be up to five times likely to develop myopia when they grow up. The researchers asked the parents of children who had been patients at the researchers' eye clinic to recall the lighting conditions in the childrens bedroom from birth to age 2.Of the total of 172 children who slept in darkness, 10 percent were nearsighted. Of total of 232 who sleep with a night light, 34 percents were nearsighted. Of the total of 75 who slept with a lamp on, 55 percent were nearsighted. The lead ophthalmologist, Dr.Graham E. Quinn, said that, " just as the body needs to rest, this suggests that the eyes need a period of darkness".
" I've already chosen question 2....above is question 2...sorry for the confusion.
