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)

I'm sorry I can't help you here. I use ComforTouch 30g Lancets in my device.

I have tried almost all types of googles these where the best yet---it just depends on the configuration of your facial features esp area where the googles lie---I apparently need shorter ones and these fit the bill. You just have to try on several brands to find out! I even tried swedish googles as well---which work well but the hurt!

These googles work great for nearsightedness! Just choose the correction is that is closest to your regular glasses prescription.

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.

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.

Yes. Looks like step 1 in the user's guide dictates that you should. Hope that helps, but you could check with Oster if there's some reason you can think of not to.

First, size. The 1.2 is huge! And the reason is also the second thing, optics. Unless you have a huge need, budget or ego, don't go 1.2. The 1.4 is amazing but the price may make you feel insecure, like it's not "good enough".

The first googles I had were a gray or blue color which I think would be good in sunlight. BUT I do all my swimming indoors so I can't really answer your question.

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

I purchased the 1.4X, after doing research on the results of both products. From what I read, the images stay "sharper" at the edges, with the 1.4x. I have used the 1.4X, and have been very pleased with the results. I do intend to purchase the 2x, understanding that the clarity may not be as good.

sigma recently came out with 17-70 version which has a C mark on it. its a good walk around woiyth f2.8 to 4. IS or OS is a good thing and its a personal decision. I have always preferred them as sometimes you forget to hold your breath for that magic moment which may not be as crisp otherwise.

You are speaking of a different product. My doctor says you want the EPA-DHA to be as high as possible and recommends my husband and I take the 720. Works well for us. Doesn't mean you can't take the 500, but the 720 will be better for you.

My suggestion is to phone Oregon Scientific and ask them. Both are their products. I've always found them courteous and knowledgeable.
