? on scope accessory

[thebuckhunter]

I was wondering if anyone knew where to get those rubber eyepiece extension thingies that attatch to the ocular end of the scope. It has a formed eye piece then an extended "bellows" like section then attatches to the scope. They are designed to keep periferal light out of the eye. If anyone knows of a canadian dealer for these, please let me know. Thanks
