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 use the Accu-Check Multiclix, Fast easy to use adjustable to skin depth, and doesn't seem to hurt as much a s a few others. Also each lancet can be used several times, though not recommended.

I'd recommend adding KH and GH, otherwise you should be fine. Also, give had great luck fishless cycling with Dr Tims ammonia (really cheap on Amazon).

If you really want a hydor, just go with their Pico line. I think they range anywhere from like 1-100 GPH.

I can fit 20 drops into one. Sorry it took so long. I really don't know what o or oo is. 3 capsules is about 1/2 tsp.

According to the RO System Performance Data Sheet, the RO-45 has a higher TDS Reduction % (96.7) than the RO-90/RO-PERM's (85.1). Of course, it is assuming that your Daily Production Rate L/day (G/day) is 40.1 (10.6) for the RO-45 and 130.5 (34.5) for the RO-90/RO-PERM. So, yes, the other comments are correct: If you have a high demand for R.O. water in your household, then you may want to go with the RO-90/RO-PERM. Just to give you additional information, my RO-90 currently has a rejection rate of 95-96% even though my family and I use less than 130.5 L/day (34.5 G/day).

Rev number should just be the revision number. Essentially like a batch number... if all the other specs match it should be fine. If im not mistaken

I am so thankful that this piece of information came up ... I called Omron and spoke to rep but he couldn't find the answer to this question ... he said this was their lowest on the list and recommended to go for the higher models.

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...)" :) :)

I ordered these 3-D glasses and they are version .63. Although .64 are considered better, I have had no issue whatsoever with version .63. Also, it is my understanding that if you receive the .63 you can contact LG and they will replace them with version .64. I have not done this so I don't know for sure if that is accurate.

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

My daughter's prescription is -7.0 in one eye and -7.25 in the other. I purchased the -7.0 for her and they work great. For you I bet that the 9 would be better as you are already very nearly there at -8.75.

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.

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

OD 90 mm ID 68 mm - you briefly boil the gasket then place onto/ around inner lid. Gives you a bit of stretch. I hope this helps you

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.
