Presciption Mask

[jlaggie]

Hello guys and gals got a quick question i need help on.
I am looking at buying a new prescription mask and the one place I found to have good quality mask cannot quite get my exact prescription.
My prescription calls for a +2.50 on one eye and +2.75 on the other
The place I found only has up to +2.0.
With the magnification of the water, will +2.0 work for me?

You should be able to get + step diopter lenses in .5 increments in a larger range than +2.0
I know it is always a great option to read the gauges. You can get exact prescription lenses as well but they cost more.
I have included what I believe to be the formula to calculate correct step diopter.

How to calculate a prescription for the best suited lens:
OD (Ocular Dexter) refers to your right eye.
OS (Ocular Sinister) refers to your left eye.
Sphere Refers to the degree of correction needed by your eye, measured in dioptres. For nearsighted people this is always (-) negative.
Cylinder Refers to the amount of astigmatism in your eye (the degree by which your eye is not uniformly round).

(There may be other terms on the prescription such as Add, PD and Axis, but these values are not considered when selecting a Step Dioptre Lens)
Although step dioptre lenses do not correct for cylinder, the cylinder number does affect which lens will best suit you.
To best select, you must add one half (1/2) of the cylinder number to the sphere number.
Note: The cylinder may be either (+) positive or (-) negative, which can make the math a little confusing. You need to be careful with the (+) and (-) signs.

+1 on Prescription Dive masks!!!

+1 Get a mask that fits you and send it for the lens to be inserted!! If you get their mask make sure it fits before you dive with it. Once you dive with it then it is yours. Trust me, VOICE OF EXPERIENCE. I have a $200.00 mask that leaks and I'm stuck.

Maybe I can make a case for contact lenses instead. If your vision is slightly impaired, there is a good chance it will get worse over time. That prescription mask will cost you many times over. I converted to contacts this year and couldn't be happier. I get much better range of vision and no head tilting for my bifocal. The plus is that I can see on deck just as well as underwater.

Another vote for Welcome to Prescription Dive Masks 1-800-538-2878..

They are very easy to deal with and do excellent work.

My wife and I both dive prescription masks from SeaVision. We also love the color correction lenses they have.

Not everyone can wear contacts, but if you can- I'd go with this option too. My doctor even offered to just give me 5 days of dailies as a sample for my dive trip, since I mostly wear glasses (I ended up just buying 90 days worth of dailies for the year.)

The problem with a prescription mask is that I either have to wear it on the boat, or I have to deal with glasses too. Based on my experience on boats, it would have been a pain to have to keep going to a bag to get my glasses or put them away before and after dives. Shore dives would be even worse, as I'd have to wear the mask as I climbed down the rocks to get to the water to gear up, that sounds like a huge PITA. My vision is a bit worse than the OP (-3.75, so not too bad) though.

Look into Mares masks.....They carry a wide range of Rx lenses for both near and distance.......
