Recreational & Occupational Uses for Press-On Spheres
•  Sunglasses - Converts non-corrective sunglasses to single vision or bifocal eye wear.  For temporary use.
•  Diver's Masks, ski or swim goggles - Adds correction to Plano lenses by applying to inside surface.
•  Hobby / Sports - Apply small sphere segments for magnification to read golf score cards, tying fishing flies, stamp collection, etc.
•  Welding mask.
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
