I have been weight lifting and taking whey protein supplement on the day I workout, but the rest of the week I have 2-3 glasses of milk with meals or snacks. Is that enough to build muscle and weight?

Okay soooo……. Glasses.
Explain how myopic people see.. (that’s what i think i am give a list Maybe?)
Okay so this is it… My school screening is 20-200 i had it done twice just to make sure the machine wasn’t broken….. And any way…. I can’t see faces on photos from across the room… i can read road signs until we’re upon them….. i have trouble seeing the chalk/white board… I can see wayyyyyyy better when i squint my eyes, using my fingers to make them look slanted….

im going to go to my first real eye exam soon to get glasses, im just wondering when they tell me what kind of glasses prescription i need, will i be able to glasses on that day or will i most likely have to wait for them to make the glasses?
thanks
or does it depend on were i go? im thinking of lens crafters or pearle vision
