My boy friend wants to buy a pair of sunglasses for me from the online stores, he asked me which kind of eyeglasses I like? Actually, I want to know which kind of eyeglasses will be suitable for me? I am 23 years old, I have a round face and a strong prescription? Could you please advise which kind of eyeglasses will suit me best?

For your strong prescription, you should choose the full rim eyeglasses frames and high index prescription lenses. And for your round face, I think angular narrow frames and geometric frames are your good choices.
