Specific style of eyeglasses?!

I presume you mean rectangular wire frames with wire temples?

While the heavy, rectangular, plastic ones with wide temples seem to be popular now, there should be tons of glasses like you describe available, try looking on some of the on-line sites. Even if you prefer to get your glasses at a local shop, at least you can see what is available without driving all over town.

For example, go to www.go-optic.com, than click on "designer glasses" when the list of names come up, scroll down to "Kashiyama" and take a look at the frames and see if they are like what you are looking for. Check out the BI- 57, 65, 80, 116, 129. 145 and others. You can also check out other makers as well. However, just because they have a picture of the frame, doesn't necessarily guarantee they have it in stock.
