How to calculate your diopter strength:

Use either of these equations to determine the best goggle diopter for your eyes.

(a) Sphere+ 1/2Cylinder = Goggle Diopter

(b)Myopia+1/2Astigmatism=GoggleDiopter

Examples:

Left Eye: Sphere or Myopia is -5.0. Cylinder or astigmatism is -1.0. Goggle diopter should be -5.0+ 1/2(-1.0) or -5.5

Right Eye:Sphere or Myopia is -5.0. Cylinder or astigmatism is +2.0. Goggle diopter should be -5.0 + 1/2(+2.0)or -4.0

Since corrective goggles are pre-made, they do not cover all diopters. If your calculation falls between 2 diopters (-3.75 for example), always pick the lower diopter(-3.5), as this will put less strain on your eyes.
