Hi I am currently selling some bike sunnies through an ebay shop at this stage.  Choppers brand mainly.

I only sell the padded ones that keep the wind out of your eyes.

Designed in USA, made in china so they are cheap but better quality than price would indicate- $9 to $20 a pair.

Cheap enough that if they get scratched or dog chews them up no big deal to buy another pair (I've been through a few, bloody puppies...)

Been using these for a couple years and find them pretty good, and everyone I've sold a pair seems pretty happy with them.

May not fit your head if its XL or larger.
