It’s the blue part of the goggles behind the eye pieces. I’ve tried extruding a circle and proportional editing but with disastrous results. What approach or type of modeling should be used? also i only have this one reference image so i can’t trace it out or anything.

The name of the product is pretty clear 
You need a certain amount of resolution to get the correct result:

A cylinder with 48 sides is sufficient, also, the picture of the top view helps too 
Thanks this gives me more images to work from… Also i now realize it’s not all one piece and the cylinder pieces can be separated. 
now i can work on this, this evening as a relaxing project… Thanks a lot.
The goggles are a single block, the lenses are obviously separated, but the body is made of a single piece, I made only half without connecting it to make it quick, as the other part is just a flat piece that connects the them together and the bridge.
Inside there’s a soft part that is made of another material, that’s there to make them wearable.
