In my experience, the legs on the cheap glasses online are rarely as long as they should be. That means the bend in the leg sits just forward of my ear.

The practical difference in negligible, though. They feel just fine, and they don't fall off or anything.

So yeah, I buy all my glasses online, and have been for years.

Most of the time you can adjust this with a heat gun. I've seen the guy in target optical do it at his desk.

They're metal legs with a plastic coating that was molded, in my case. Can't really bend them or reshape them.

And for the plastic ones, it would mean the ends of the legs would be rather short, leaving them to sit funny on the desk when open and possibly more likely to fall off if you lean forward.
