The direct eye contact story is actually what Oakley JP and its Japanese premium dealers told fans in 2005 or 2006 if you asked them about why there were so many clear exclusives in the Japanese eyewear lineup (Hatchet titanium clear, Gold and Ruby Clear Unknown, Ti Clear Juliets). Whether this is actually true or just lip service is unknown, but that's what their official answer was.
That's very interesting. But also very odd since by making the lenses almost clear, they are no longer sunglasses, although they do allow for eye contact!
