types of optics for either temporary or long term corrections.
Press-On™ Prisms, also known as Fresnel Prisms, and Press-On Aspherics, provide
a system for creating prismatic and
spherical corrections is simple, inexpensive, and fast.
Press-on prism material is flexible static vinyl which can easily be cut to
shape with scissors to determine the acceptance of a proposed corrective
prescription. Adheres well to existing lenses, yet it can be repositioned and

Press-On™ Aspheric Lens and D-Segs (bifocals lens)
For Rx Corrections. May be used to adapt sunglasses to bifocals or swim goggles or dive masks for Rx correction.
Although similar to your glasses prescription, for use in the
water requires a quick calculation to ensure that the proper strength is
selected and post-swim headaches are avoided. Looking at your prescription,
you'll want to locate the sphere and cylinder for each eye. Use
the following formula to find the right diopter lens for you:
(1/2)(Cylinder) + Sphere = Diopter. 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 or open file to use formula to determine the correct lens strength .
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 - call 1-800-544-4760 or go to www.myipatches.com
