RX inserts are prescription lens carriers that fit inside certain types of eyewear, such as sports goggles, safety glasses, or motorcycle helmets. Instead of placing prescription lenses directly into the outer frame, the insert holds customised lenses behind the main shield. RX inserts allow people with vision correction needs to use performance or protective eyewear without wearing separate glasses underneath.
