Cheap but usuable
Although these glasses look like military issue (pilot or aviator, they are not. They are plastic and do not have the same strength or weight that you get with other brands such as AO (Aviation Optical) or Randolph flight style glasses. However, for the price, they will do just fine. If your expectations are for higher quality, then spend the extra $20. But, if you want an inexpensive alternative, these will do just fine.
