My OD is (sph -3.25/cyl -1.0 )and OS(sph -3.25/ cyl -0.75). How should I choose the googles?

Remember these are basically keeping water out of your eyes and not for reading. I chose the prescription that was closest to my actual prescripton and they work very well. I have no issues with fogging if I put a little surface tension reducer (spit) inside then rinse them out.

-3 ought to work. They are not going to be perfect- they are not custom googles but are just going to be better than non-prescription!

Click SELECT in the ad and you'll see options available. Choose the one that is closest to your degree. In your case, -3 or -3.5.

The lenses in these are not as sophisticated as the ones you would get from an optometrist. Consider the price! As a rule, I normally go down rather than up, so in your case I would get -3 (rather than -3.5)

For any Olympus body except the OMD EM5 (or any future bodies with 5 axis in-body image stabilization), use the lens OIS with the Panny 45-200. Pretty much everyone agrees OIS is better than IBIS with this combo.

I think -4.0 and -4 are the same. If you are near-sighted, you should choose negative.

Massive difference on the bokeh side - the 85/1.8D has a (subjectively speaking) nasty rear defocus rendering. The G OTOH seems to have quite a pleasing bokeh.

16 1/8" ID, 16 1/2" OD (There is an outward curving lip which creates this much difference.) ... Strange that I measure such a difference from Paul's answer.

O.D. is 3/16"or 0.5 cm. If you looking for closer precision, you will have to get some serious drawings, otherwise these measurements are from my kids ruler and my eyeball.

Od would be 26.67mm, according to engineering toolbox that would be a 20mm sch 40 if such a thing exists, the threads would have to be imperial threads tho.

The numbers 1.25, 1.5 etc refer to the maginification of the lens, the reading glass strength. The frames are all sized the same, for a unisex head shape. The temples are adjustable in length assuring a comfortable fit on a wide variety of head sizes. You'll need to know which power (+2.0? or +1.5? ect) you'll need for the lens of course. Thanks,

Mine is 24.84. According to their site they have switched to 25.5 so there is a disparagement in mine and what their official site claims. I read somewhere else they switched at some point so I may have an older model.

Mine is a SPX0710XD. I do not know what the O and X difference would be but the spider gasket worked fine for me.

Monica W., Changing the O/S will not void your warranty. Also, while we cannot guarantee that any particular version of Linux will run without issue, we do not expect you would experience anything out of the ordinary.

I have never had any reason to look at either of those numbers. I guess I would contact the manufacturer & pose the question there. Or, you could use the old method of trying both types and see if you can find any "difference" (that's my method of solving a question...)" :) :)

By my measurements as it sits on my S100, OD=29mm+/- 0.5mm (approx. 1.15"); ID=26.8mm+/-0.5mm (approx. 1.05") It fits the S100 perfectly. I'd check the mfg specs.
