holding book close to eyes

while for ages we have been told to hold the book a little far while reading, i came across this article that says that this is in fact a myth! take a look.. http://mayoclinichealthsystem.org/locations/la-crosse/services-and-treatments/ophthalmology/myths-and-facts according to this, children can focus as per requirement even when the book is close, and this will not cause any stress on their eyes and not lead to myopia. this article also says that there is really no way to prevent myopia, and that reading and screen time won't really cause or worsen it. https://medlineplus.gov/ency/article/001023.htm
