* Used for refractive +/- correction – these are not prisms.
May be used to adapt sunglasses to bifocals or swim goggles or dive masks for Rx correction.
3M™ Press-On™ D-Seg Bifocal Lenses are great to use to alter sunglasses or in swim goggles & dive masks to add magnification to allow easy reading of gauges, watch or camera. Available to all, no Rx needed.
3M™ Press-On™ Optics are inexpensive, per-diecut, and may be used for temporary or long term solutions.
For use in water, use the following formula to find the right diopter lens for you:
(1/2)(Cylinder) + Sphere = Diopter. (found on your most recent Rx)
Water will refract light and correct vision a bit without any prescriptive power applied.
With that in mind, always select a diopter strength that is one step lower than the outcome of your calculation
