ScubaSpec Dive Mask Prescription Insert 199 EB

The 199 EB Scuba Spec is a prescription spectacle insert specifically designed for the visually deficient diver. The 199 EB Scuba Spec attaches to the dive mask via an anchor bracket which is bonded to the glass faceplate. The Scuba Spec prescription insert can be snapped in and out of the mask at the diver’s discretion. The same prescription powers used in the diver’s habitually worn glasses can be used in the Scuba Spec insert (single or bifocal vision).
