 * 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.
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

These may not be returned as they are cut for each order. – Sorry

International Orders may be accessed Duty / Taxes at the time of delivery – these are not pre-paid
