OPTICAL INSERT ANTISHOCK PIN X4 parent_sku_AEROWATT-FOZA_ps This historic milestone stands asSet of four mushroom shaped silicone pins designed to be applied to the prescription lenses of the optical insert. They act as a buffer to prevent direct contact and potential scratching between the insert and the sport sunglasses' sun lenses. The pins are mounted between the Nylor thread and the prescription lens, which must be shaped with a small notch.
