Currently the goggles item uses less iron than the standard iron helmet while it uses other ingredients this can technically make it easier to obtain. I would suggest updating the recipe to either use an iron helmet in the crafting or have the same 5 ingots. Alternatively modifying the goggles into a purely functional item that does not double as armor could be useful especially when paired with #69.

or making it an enchanting book so players can apply it to their preferred headgear
