The 0.4 lens is a bit bigger than I thought it would be but that is a good thing. The lens coverage is great with a great light fit. Leave them on for a few minutes and you can forget your even wearing them.
The design is more subdued and does not get as much attention as the the others can but you still get that nostalgic feeling when wearing them. A great pair to get into if you looking to start a collection of the Zero lineup as there seem to be plenty of 0.4 in good condition available
A worthy pickup for sure.
