For ready-made swimming goggles!?
It's more of an approximation than a calculation: in your case -5!.50 R&L would be nearest, but if half-dioptres aren't offered, go for -5!.00!.
At the ranges used when swimming, slight undercorrection is less of a problem than over-correction!.
Half the cylinder added to the sphere, averaged between the eyes and rounded down, roughly!.
But that might not apply if one eye is strongly dominant!.Www@Answer-Health@Com

in ophthalmology the name goggle is not used for a spectacle lens and it is called FRAME OK , ,goggles means a wear for pleasure full experience in people who do not bother about the small time wearing or forgetting the power or having no power,-----!.you have exposed the power you need to see and ------your visual acuity,---- you have not shown to tell you how much you are seeing and hence---------- your expectation is partly AttendedWww@Answer-Health@Com
