Guide: Scuba Diving with Prescription Mask, Stick-on Lenses or Reading Glasses

[CG43]

Lenses both sides in the water !!!

DiveVue - Mount glasses to your dive mask.
In the page you can read :
When selecting cheap reading glasses, we suggest selecting glasses with a magnification 0.5 less to equal your existing reading glasses (i.e., +2.0 down to a +1.5 magnification) .

That is wrong !

Air has an refraction index about 1,000 :
water about 1,33 : and cheap glas about 1,5 .
The difference between glas and water is much less then between glas and
air .Therefore, the glasses (the visual aid) lose most of their optical refractive power. A pair of glasses for + 2 diopters in water is probably not to buy.
The lenses would have a short focal length , would be thick for a sufficient field of view , and will have a lot of optical errors .
Or you can take two lenses with air in between. But this glases must then be pressure-resistant.
For deep freediving competition , however, there are contact lenses with very high diopters whose curved front is in the water.

A little ways back, I suffered an illness that has affected my vision and now I can't see things up close like being able to read my computer and other gauges. My long distance vision is still relatively still good, I just need correction up close mainly. I am going to see my doctor in a week and find out my exact prescription needs. Since this is all new to me, I am seeking a little advice. I dive a mask that is no longer made (I actually have two of them) and I absolutely love the mask, therefore, I want a prescription lens put in both of the the masks (want to carry a back-up). I don't know this is even possible, but my mask is a single lens mask and I was wondering if anyone out there could make a full lens the exact size & dimensions as my mask and either replace the factory lens with the prescription lens or make the lens the exact size & dimensions as the factory lens and bond it to the factory' lens? If so, what companies would you recommend?

I greatly appreciate your time & assistance.

i am. like you same problem.

they told me you could not put a lens on a single lens mask. could not tell you why.

Other than that i have my prescription lens in my mask really like it worth the money !

You can send your mask to Custom Prescription Dive Masks . They make lenses in any prescription and bond them to the inside of the existing scuba mask glass. They do sell new masks, but as long as your mask has flat tempered glass, they can use it.

Once you have your prescription, give them a call.

I've had 3 masks made by them over the years as my prescription has changed. They all work perfectly.

There is probably a fear that the distance between the eyes and the lenses will increase too much. With simple + or - diopter lenses this does not make much difference in my experience, but there are more complex corrections and I do not know if it becomes more critical here. You can try holding your normal glasses at a greater distance and tilting them to see how sensitive your interpupillary distance and angle are. However, this only applies if you want your diving glasses to have similar optics.
