What strength eye glasses do I really need?

I'm trying to understand my vision. I'm 55 years old and I started wearing readers around age 45. I'm currently wearing nonprescription readers at 2.00. I've noticed when I try to look at something small like a medicine bottle,
the words seem to be blurry. If I get a magnifying glass it makes things more clear. When looking at my iPhone the words are somewhat blurry but when I move my phone to arm's-length it's more clear. Something I did find strange was one day I had my readers on and my prescription distance glasses on top of my head. The distance glasses fell over my readers and as I was looking at my iPhone everything became sharp and clear. I even mentioned that to my sister and she did the exact same thing and she said wow it was much more clear for her too. Yesterday I went to an eye doctor and he wrote a prescription of +.75 both eyes for distance which is the same as three years ago. And he wrote +2.25 in both eyes in case i wanted bifocals. I currently have no prescription readers. Three years ago I was wearing the same 2.00 readers and he told me they were too strong. Now yesterday he told me they're not strong enough if when I'm looking at my phone and it's blurry but after I push it to arms length it gets sharper. He says I need a stronger reader. Is that correct? Seems like if my phone for example is blurry holding it at a normal distance then it gets sharper as I push it away from me, then the glasses are two strong. I'm so confused.

Iphone 5s case, storage and icloud?

I need a iphone 5s case. I want something slim, but as protective as a slim case can get. I want something that looks nice too. And… I have a price ranger. I want it to be cheap. Like $15 tops. Ik there's like no case out there for what i'm asking for. But anything similar?
please help.
and also, i have a few question. I kinda know what icloud is but not really. What i know is that whatever you put on icloud, it is backed up. But everybody like if you have to much music, just put it on icloud. But i though it only backed things up, i didn't know it was extra storage?
and say you have 1500 song on your itunes on your pc. When you sync you ihpone to the pc with 1500 song, can you pick and choose what song you want on the phone. So say for this month i only want 200 song, but the other month i want 500. Can i pick and choose what to put onto my phone. So instead of having all 1500 song that i won't listen to taking up space, can i only put 100 on and not take up as much space?
