new glasses

I went to an eye doctor recently to have a check-up concerning my eyes. I have been complaining about having blurry visions from afar. I used to have eyeglasses before but it's for correctional purposes only. Years before, i only have astigmatism and consistent use of my eyeglasses will help me regain my 20/20 vision. but due to hardheadedness and lack of discipline, i only use it for emergency purposes. Until i lost my glasses and needed a new one. The doctor told me that my eyes are already 125. I dunno what the hell that means but i know it's quite serious. she also told me that my nearsightedness is unfortunately permanent. I have to use this consistently for 1 week so that my eyes will get use to it first. Then after that, i will use it if needed only like driving, watching movies or television. can u imagine? using glasses in watching a movie? it's madness to think that a screen so big isn't enough to make one's eyesight perfect. geez... but does it suit me though? i chose a frame that would be perfect for my face and not old enough to look at.
