I just got my first bifocal eyeglasses via the internet, I have wore it for 3days, but I found that my vision goes completely blurry if I take them off....is that normal?
I phoned the optician who sold me the glasses, he told me that it takes me several weeks to get used to my new eyeglasses.
I just want to know is that true?

Usually, you need some time to adjust to your new eyeglasses, specially for bifocal glasses, you maybe cann't acclimatize yourself to the line or you may feel dizzy when you up or down stairs, but it is really quite nomal, you just need time, if anything won't change in a week, you should come to the optician who sold you the eyeglasses to check them, good luck!

Yep ,that`s normal case ,you don`t have to worry about that ,and not only bifocal eyeglasses but also progressive eyeglasses need time to adjust yourself to it .Take it easy.
