Adding outdoor time in the mix is also important, says Repka, who cautions schools to keep physical education time a priority. A recent analysis of eye health research by members of AAO suggests outdoor time is related to lower rates of nearsightedness in children and young adults.
One of the key factors in this correlation is the amount of distance viewing that comes naturally in outdoor activities versus indoor ones. While the results of the analysis require further research, Repka says the findings add "fuel to the fire that 'near work' is a problem."
