-2 diopter worked well, let’s me see the stopclock on the pool wall to time my laps. Only complaint is that nosepiece not adjustable so pinches

Normally I wear glasses that have a complicated toroidal (astigmatic, cylinder) prescription with a progressive bifocal “add”. The average spherical equivalent diopter is probably -8.5 or even -9 with a 1 diopter or so difference between eyes (didn’t bother to calculate). Custom goggles with just my single vision prescription would cost $200 at an absolute minimum and realistically more like $300.
But I know you don’t always need the exact prescription to see well enough in non-reading, non-detailed-work type situations.
So I ordered the -8 step diopter goggles and they work well enough for swimming. I can read the lane numbers, the clock on the wall, and recognize everyone both above and under water. The goggles seal well enough, and the comfort isn’t perfect but good enough for 1-2 hours. So far the anti-fog is working but I expect that to wear off eventually because it always does. By the time that happens it might be time for new goggles anyway.
So if you’re wondering if you really need expensive custom goggles, then for most people probably not. Some people may if they have a higher difference between eyes, more severe astigmatism, or prism and really need custom lenses to avoid a headache, but for about $20 it doesn’t cost much to buy some off the shelf step diopter goggles and see how well they work.
The approximate process for finding the closest step diopter lenses for your prescription are:
1) add the sphere for both eyes (OD/OS) and divide by two. In other words average them together.
2) if you have “CYL” then you need to find the “spherical equivalent”. Divide CYL for both eyes by 2. Then average the resulting numbers together. Then add that to the average sphere from step 1.
So let’s say you have OD -5 sphere and OS -6 sphere. You’d average those to get -5.5 in which case you’d need to pick -5 or -6 (might want to pick dominant eye or ask your optometrist).
If you had OD -5 sph -2 CYL and OS -6 sph -1 CYL you’d get -5.5 sph + ( (-2/2) + (-1/2))/2 = -5.5 + (-1.5/2) = -6.25 thus the choice of -6 would seem to be more obvious.
Ignore “axis” since that only applies to CYL which is averaged out anyway, and ignore “add” since that’s the “reading glasses” part of a reading glasses or bifocal prescription. If you have prism then definitely ask an optometrist.
Truthfully though, I wasn’t even that scientific about it. Just kind of looked at the numbers and went “yea better get -8” because for me the math would result in something slightly lower than -8 anyway. And -8 is still working fine.
So just try to get the closest thing and you’ll probably be ok. But the optometrist you got your prescription from would probably be able to tell you for free, in about 10 seconds, what the closest step diopter is and if it’s likely to give you a headache.

It doesn’t make the glasses foggy I was shocked. This is such a good item.

I have been wearing these inexpensive goggles for many years. My vision while in the water is super, and they comfortably conform to my face perfectly- no water seepage.
They are plastic, and eventually ( several years) need replacement . They are SO worth it .

These work great for my very nearsighted kiddo
