Re:snorkel mask w/ prescription lenses. to correct my nearsightedness, do I enter the ""DV" or "NV" number? my NV is 2.25. should I order 2.5?

I ordered the mask for my girlfriend who is near-sighted. She gave me a copy of her prescription. Under the "Dist" part of her prescription, sphere is -8.5 which is the number I used when I placed my mask order. I am assuming "DV" is distance, and "NV" is near. If so, I believe you would enter the "DV" number. The mask worked great for my girlfriend. She said she could see better out of the mask than her glasses. Hope that helps, Brian H.

When you snorkel, you wouldn't be using your bifocal lens. You should order the lens that you need for distance sight.

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,

Yes, that is what it means. I did the same thing that Wanda did. When I went to the Optometrist and got bifocals for work I mentioned that I just got drugstore glasses for reading at home. He asked what power I was buying and I said 225's and he said "Well, next time you buy some get 250's which I did. I love these glasses, they look nice and fit comfortably. Get them.

I have different sizes for different areas. I have been using the 1.0 for my face, 0.5 for around the eyes and 2.0 for body areas. I hope this helps. I actually did my face last night.

I am so accustomed to wearing a snorkel, I haven't noticed that it impairs vision at all. I wear goggles every swim so, I would say its safe to wear a mask.

Michael - Thank you! Thank you! Thank you! I just educated myself on the 10-22 mm and decided that is the lens for me! Now to save up... :)

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 just received my order. Right on the side of the box for Model DPG28 it has a label that says: "99.9% UVA-UVB Protection."Can we please just retain what we "think" and only share what we know? I was wondering this same thing before I ordered, and the comment below almost caused me to not purchase them. Then I figured that it would almost be impossible to have darkened lenses that don't offer any such protection, so I looked it up online and found a vague answer saying that they did offer some kind of protection. Very pleasantly surprised to see that they offer such thorough protection! I just received my order.

Sorry, our lens only adjust single vision. If it is for snorkeling, bifocal/reader lenses are not necessary.

The "Telephoto Lens" that came with this package is a "Vivitar Series 1 - High Definition 2.2x58mm" with the number 1090413 on the lens itself. Maybe I am stupid but I do not know what IS means. On the folded paper that came with the lens, which is the "user guide", there is nothing on the paperwork that would indicate IS, whatever that is.

I recently had cataract surgery and I am now farsighted. Standard 5X magnification didn't help at all, so I went for the highest one I could find. If a 5X doesn't work at all for you, go for the highest magnification.

Id say pick the 17-35 if you intend to stay on DX size for another 5yrs... the 50mm covers the middle of the 24-70 so moving your feet will cover that distance, but the 17-35 will allow for group shots and landscapes/buildings... the 24 will limit that somewhat.... my2cents!

I'm considering CBRN Requirement and using only NIOSH approved masks too. They're much more expensive though. Looks like the SGE 400/3 BB is the lowest cost mask that meets the requirements (maybe)

It mostly depends on the width of your face as to the size, at least that is what I found. I have what most would consider a pretty average - male - face in medium worked fine for me. Make sure you get the right filter for vapors and should be great. I would never go back to a 1/2 mask as the full is so much more comfortable and protects the eyes. Happy spraying. PS, I noticed that you said mold. If there is mold there now make you have a mold filter and please wear a full suit for own good.

Vision is relatively normal with snorkel in position, I use swim goggles and the fit together fine. Mask would be too big.
