Can I Just Buy Over The Counter Reading Glasses Instead Of Filling My Glasses Rx?

I just got a prescription for glasses- Dr said that I should use them anytime I am reading, on the computer, watching tv etc. My rx is +1.25 in both eyes and astigmatism in my right eye only -50. Would I be able to buy over the counter reading glasses and get the same results?

Astigmatism Laser Eye Sergery? (filling Up Space)?
