Dear Dee and Emma,
Wore glasses since childhood, and nothing makes you feel better than finding a style that flatters you. Presently sitting in a Seattle WA cafe, with my trusty second pair by my side . . .
Never ordered glasses online, although it is available in the US.
Feel that it is very important to get your glasses properly fitted for comfort and for looks. Personally, I don't like the top of my eyewear to be under or over my eyebrows, and I don't like my eyewear sticking out beyond my face, or not coming to the edge of my face.
Your friend,
Monica
