I have -1.5 myopia and .5 astigmatism in one eye, but I only have -.5 myopia and .5 astigmatism in the other. The optometrist prescribed me glasses and told me I need to wear them, but I don't because I can see very well with both eyes so I don't see much of a difference with or without glasses. Is this bad/should I be wearing them or is he wrong? Thanks
