"Rotcho OTG (Over the Glasses) Goggles is the inexpensive and high quality solution for airsoft safe eye wear for people who wear glasses. Their large frame accepts most types of glasses so you do not have to spend a ton on really expensive goggles and having to get a custom prescription filled out. These are ballistic rated and are ventilated to resist fogging."
