I’ve seen countless images of the Grand Prix legends of the 1960s with a bit of gaffers tape obscuring part of their goggles. I never really thought about it until I saw this rather extreme example of Graham Hill’s. Does anyone know why they did this? Was covering the top half of the goggles done to block out the sun? Was it to isolate the extreme motion of items in their peripheral vision? Was it simply to strengthen the goggles themselves?
