Not really true
Prolonged use of the eyes, especially for near tasks such as reading, sewing, or computer use, can certainly lead to "eyestrain" or tired eyes.
No real harm is done, and resting the eyes by closing them for a few seconds, or staring at something far away instead of near by is helpful. In children
, many eye doctors
think that prolonged use of the eyes for near tasks, can increase myopia (nearsight).
