I just want to put a plug in for the EyeWear Pavilion in Albany. They carry Wiley X ballistic eyewear that the US military uses and Duraflake uses for prescription safety glasses where I work. They worked with me to get a prescription set of glasses for shooting pistol at steel targets safely, where the bifocal is at the top of the glasses instead of the bottom and focused for the front sight! They work great. So pass it on if anyone shooting iron sights at steel need a good pair of prescription shooting glasses.
