I was recently sent these images of my goggles in their pre-welded state. I think you’ll agree that they look simply gorgeous as they are!The lenses are camera filters. Just the cheap UV versions that you can now get second-hand from camera shops that have a second-hand section or car boot sales. The reason I chose filters was because of the welding. I decided that the extreme temperatures may melt traditional plastic welding lenses whereas the camera filters have a metal ring around the circumference which should offer enough protection.
The fork has a small bend in the prong which is to attach the two goggles together in the middle. Something I nearly forgot!
