Before the radioactive spider bite, I used to wear thick glasses.
"Used to wear" shows a past state (wearing glasses) that has completely changed in the present.
I also didn't use to have any muscles at all.
For the negative form, we use "didn't use to" (without the "d" on "use"). It shows a past state that wasn't true before, but is true now!
