Hi,
Your friend has high myopia in which far vision is a problem for which lenses/glasses are given for correction for distant vision only at such young age. For near vision, glasses have to be removed and then seen.
There are other issues also related to such high myopia for which your friend should get evaluated like dilated retinal evaluation for retinal periphery.
