Hey I recently bought a pair of goggles, usually I'm good at find out information on the internet but I'm having a hard time. These goggles don't have any markings and I don't even know what they'd be used for. They have an aluminum frame (I think), orange/yellow lenses, and I think the previous owner changed the original straps to sewn on shoe laces. Also, I found out after I bought them that the sides of the frame come up and the lenses can be removed. Any info regarding these would be great even what they were used for. Also, I'm a newbie to the forum so tell me if I need to change anything.
