Made for use with the Aqua Sphere Eagle Swim Goggle, the Eagle Optic Lens is a breakthrough in design offering optional interchangeable optic lenses that bring clarity back to your swim. Eagle Optics clear lenses are designed to provide the greatest visibility indoors or in low light. 100% UV protection allows you to swim in full sunlight without the risk of damage to your eyes. Durable, polycarbonate diopters are individually available in half-step increments from -1.5 to -6.0, ensuring you'll have perfectly customized visibility without having to purchase multiple pairs of goggles to match your vision needs. Also, an updated easy-adjust buckle makes fitting easier than ever! Aqua Sphere Eagle Optics give you the confidence of clear, enhanced vision while swimming. Quick and Easy 4-step "pop-and-swap" diopter-lens replacement process. Additionally, Eagle Optics Corrective Lenses are fog and scratch resistant. The Lenses are interchangeable, so you do not need to specify Left or Right.

Finding Your Diopter Strength

Although similar to your glasses prescription, swim goggle diopter lenses require 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

Example: If your left eye (OS) has a sphere of -4.5 and a cylinder of +.25, your diopter strength would be as follows:

(1/2)(.25) + (-4.5) = -4.375


Remember: Water will refract light and correct vision a bit without any prescriptive power applied. With that in mind, if your calculation does not end with a .5, select a diopter strength that is one step lower than the outcome of your calculation. In the example above, with calculation of -4.375 you should order a -4.0, not -4.5 diopter strength. If you need help, please give us a call or open a chat session for guidance.
