Right now, my eyes are -7.5 and -6.5 in each eye. I recently bought glasses according to my current prescription. However, whenever I read, it puts a huge strain on my eyes and wears me out. I have a pair of old glasses that is around -5 in each of the lenses. Is it ok for me to use my old glasses for reading or using the computer and new ones for everything else/farther away activities?
Added (1). Also, is it ok to use the old glasses when i'm just walking around the house/ doing chores?
