Combine the sphere (sph) and cylinder (cyl) values into a single spherical equivalent To convert your prescription for swimming goggles from the format you provided (sph -4.00, cyl -1.00, axis 180) to a more common spherical format, you'll need to combine the sphere (sph) and cylinder (cyl) values into a single spherical equivalent. Here's how you can do it Calculate the strength of the diopter you need using this formula 1/2 of the cylinder + sphere = diopter strength > Sphere (SPH) is the degree of weakness in diopters. This is always a negative number for nearsighted people, and a positive number for farsighted. Cylinder (CYL) is the degree of Cyl power in your eye. Add half of this number to the sphere to determine diopter strength. > Enter the Sphere and Cylinder values from your prescription into the Lens Calculator below and click the Calculate button to determine which diopter strength would best suit your needs. > To choose a diopter lens, simply find the one that has a prescription closest to your own. A general rule of thumb when choosing a diopter lens is to round down — rather than up — to the prescription that most closely matches your own. This places less strain on your eyes. > For example, if your prescription is a sphere of -5.0 and a cylinder of +2.0, then (1/2 x +2.0) + -5.0 = -4.0 step diopter lens. Or if your prescription is a sphere: -2.0 and a cylinder: -1.0, then (1/2 x -1.0) + -2.0 = -2.0 (rounded up from -2.5) step diopter lens. > For example, if you have a prescription -3.00 -1.00 x 180 OU in the swim goggle, you would prescribe -3.50sph OU. When you have a high prescription of -8.00sph OU in glasses, you would keep the same prescription (-8.00sph OU) for the swim goggle prescription, as opposed to giving -7.50sph OU. The reason for keeping it the same is when you are underwater things will appear more magnified, so it already takes into account for vertex distance. > Note : OU - Both eyes oculus uterque Review: Best power swimming goggles. - The quality of this goggles is very good and the most important thing it's power is accurate.
