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)

Go to the following website & you'll find a complete Oregon Scientific base & sensor compatibility chart, hope this helps. http://www.weathershack.com/static/osi-sensor-compatibility-chart.html

That's the method we used when buying my daughter's goggles. She ended up with -3.625 (R) and -4.25 (L) so we split the difference with a -4 prescription. She says they work well enough for her, and she has to be read a white board to get her workout during swim practice.

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.

Any would do. If u feel better get the 1.4. ... Can't see or hear any difference.

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 LS2 OEM web site's sizing chart was an exact match for me with my oval head. Now, if you have a round head you will need to go down a size.

I do not know what 'cyl' and 'axis' measurements are, but, here is what we did:1. when ordering Speedo goggles, we got the +/- number, from our opthomologist.2. when ordering the ProMate snorkeling mask, we selected the the color and then selected the appropriate eye-adjustment (my son is nearsighted) from the "size" pull-down menu on the ProMate scuba options.3. My 13 year-old son loves the mask and was our family underwater photographer in Cozumel.

I would definitely start with .5 because after almost a year I still peel with it. I couldn't imagine using the 1.

I would get a 3000 pure sine GP-SW3000-12. I can't find the 3000HD one to be UL listed.

The OTC Version is only 27 mg vs the prescription 40 mg. It is working for me just as well as the 40 did so it is worth a try.

Hi Alexander, I think "OS" stands for "One Size" as in one size fits all, but in this case I don't think so. It is a nice mask from all the ones I've used for lap swimming but they don't give enough length on the adjustable straps. I don't want to discourage you from purchasing the mask, first see what the return policy is and if there is no extra charges on returns give it a try. Happy swimming!

Yes, these are the googles I have. Might need to bend/adjust face mask a bit.

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.
