does kid's eyeglass frame can be processed with bifocal lenses?

[eyeglasses men]

My face is too small like a baby face. Sometimes, i buy the eyeglasses with kid's size. But, recently, i update my prescription, the eye doctor told me that i need wear the bifocal eyeglasses. Meanwhile, i noticed that there is a ADD value +0.75 in my prescription. Thus, from *********, i find a content frame, OLC1209, how to buy it with bifocal lenses?
