Rx insert for ess eyeshield - ESS P-2B™ Blank Rx Lens Insert, 740-0311

While they are light weight and hold the Rx lenses in place properly, they are thick enough to interfere with peripheral vision. The wire ones may be better, I'll try them next time.
Pros: relatively inexpensive, lightweight
Cons: way too thick
