E Frame doesn't have the bottom vents to nowhere cut-outs.Two posts? E FRAMES
O Frame (1st Gen - Ver. 2 or 3) Goggles. Commonly used for motocross - or as youth snow goggles, as they are on the smaller side.
These could be snow goggles or motocross goggles but with a snow goggle lens. As MX lenses would have a black pin on L/R edges of the lens to use with tear off clear sheets, typically single vented lenses. Those lenses are dual vented persimmon.
Dual vented lenses have an outer lens that's tinted, and inner lens that's clear. They are glue together with a small gap between them in the middle which aids them in not fogging up; outside air is cold vs. air around your eyes is warmer due to body heat, the space between the lenses is meant to act as a buffer zone to even out the temps so the lense don't fog up - if the inner lens gets cracked it'll no longer perform well for cold weather, but can still be used in warm weather. As with warm weather you don't have that issue of drastically different temps, so they can just use single pane lense with anti-fog coating.
