Check out www.prescriptiondivemasks.com. I hate the feel of contacts & have a very strong prescription. I had bought a Scubapro frameless mask, which I love, but it's quite low volume. They worked magic & put two fantastic lenses into my mask; feels great, and I can see. Because of the severity of my prescription, they needed to use high index lenses which ran me about $175 instead of $100, but it's well worth the cost. My prescription hasn't changed in years, so I decided to splurge on this now...

If my prescription had been changing significantly every couple years, I probably would've learned to deal with disposable contacts. That's what my wife uses while diving, and she loves them. Then again, she's got decent vision even without them, so if they get washed out of her eyes on an unexpected mask flooding or something, she can still see perfectly well to complete the dive safely.

Thanks Jim! I'll check out the site. My problem will be how they will able to fix up a lens for me with me not going stateside. Hydroptics (a company Web Monkey is recommending and I came across) is offering that I just have my eyes checked here locally (Philippines) and send them the results and they'll work it out stateside and send the mask here to me.

What's bothering me is that will it be correct or how will it turn out.

Hmmm...this is giving me a very good idea...why not set up a business here in the Philippines helping people like me suffering the same dilema?

There are no companies here that supply and or provide prescription lenses for dive masks.

Thanks Jim!
 
Thanks archman, jerryg, and hallmac...I'm not DIR cert either. Like what archman said, I find interest in what they believe and practice. Thanks for your posts.

But to comment on jerryg's post...okay, I can suck up to the pain and danger of having lasik surgery (I'm still cringing at the thought). But the cost of it...WOW! Here in the Philippines it's about $1000usd per eye. That's $2000usd for both...hmmm...that's about the best bp/wing from dive rite, the best regulators in the market, wetsuit, fins, and the whole bag of other stuff...LOL...jerryg I'd rather go diving half blind but with all them cool stuff :). Thanks!
 
You may want to consider giving contacts a second try. It took me several makes before I found really comfortable ones. I can't even tell I'm wearing the ones I have now and they never come out under water. When I swim I often open my eyes (not wide) and have never lost a lens yet. BTW you have salt water in your eyes now!

I have a totally different solution. I use glasses which are made to go inside of a gas mask, for example in a refinery. They are made by a company called Vallen. They fit easily inside of the dive mask and are secured by a thin adustable rubber strap around the head. They can be worn all of the time on the dive boat or during beach dives. I must admit that it does look a bit staange, but it does work well and I do not really care what it looks like anyway. I do not know how much they cost, as the company I work far buys them for me as a safety item. I do not think that it would be very much however. I hope that this helps you and others. ;)

Thanks Terry! Yes, I came across the Hydroptics site. They do have some tricked out mask! And they do have some hi-tech way of explaining stuff. But that mask is way too pricey for me..just like the sea vision masks. I'm thinking I could already buy one very good mask and some other stuff!

I'll let you know if I give this mask a try. Thanks!


I have a hydroptics mask. But have 20/20 vision.
And I'm unwilling to do contacts to make me nearsighted.

However. My sister and dive buddy are both nearsighted and they love the mask. No distortion, and perfect/nearperfect vision without contacts for them.

The volume in the hydroptic mask is a bit more than a normal mask, and prolly not DIR. But do you really care ?

I've seen new hydroptics masks on eBay for at or near $100.

Best of luck in whatever you choose.

...until a couple months ago. Like you, I started wearing glasses at age 8, and the lenses were very thick. Something in the neighborhood of 7.5 diopters. I had 20/300 vision in my right eye, 20/200 in the left. I watched LASIK for a very long time. Finally, my optometrist, who I really respect, sat down with me and told me I was the 'ideal' candidate. My eyes are very healthy and very, very stable with very little change in the prescription from year to year. Like you, I would put my glasses on while in bed in the morning and then get up, and take them off as I turned off the light at night to go to sleep. When traveling, I would wear a pair of glasses and carry a spare pair in my pocket and another spare pair in my luggage. I was scared to death that something would happen and I would lose or break my glasses and not be able to function.

Finally, after reading everything I could get my hands on about LASIK and three years of urging from my eye doctor, I made the appointment for the prescreening. Got through that first several hour long appointment and filled out all the paperwork. Paid my money and got my date set.

The night before the actual LASIK procedure, I had a MAJOR panic attack in the middle of the night. Woke from a sound sleep, sounding like I had just run 10 miles, covered in sweat.

Went in for that procedure, in a middle of a blizzard, with nearly a foot of fresh snow on the streets, with my wife in tow to drive me home. Sat in the waiting room for an hour before going in for the 'prep' and sitting nearly another hour waiting my turn. Got led into the Laser room, and on my back on the table, just as they got ready to make the first correction, the power in the room blinked out for a second. OFF the table, back to the waiting room while they reboot the computer and test the machine for index.

Finally, back on the table. One eye took 45 seconds to correct. The other took 48. The procedure is completely painless, I never lost my vision. Got off the table and could see without my glasses! Close your eyes, go home, go to bed and sleep, use pain medication, use antibiotic eyedrops, see the doctor in two days.

Well, it's been nearly 3 months now, and my vision in both eyes is 20/20. I wear reading glasses, like most men my age (50) and wonder why I didn't do this a long time ago. I get to wear regular sunglasses. My eyes don't fog up when I come in from the cold like my old glasses use to. My doctor says you can't even see where the incision was made in my eyes. I can't remember being happier about a decision than I have been about my LASIK. I just wish I could have done it years ago.

My mask, both of them, have regular lenses in them, and I can see to rig my drysuit hood and walk to the water.

Don't discount LASIK so quickly, unless you have all of the information about the procedure and how it will work......

I really hope I posted in the right forum.

I've been wearing glasses since I was 7. I cant eat, walk, work, without them.

I'll have to take them off during diving, I don't like contacts so I was hoping if there are any suggestions of prescription masks that would work for a DIR setup...meaning a DIR mask.

I was initially looking into the Mares ESA tech black.

Please don't suggest LASIK...it scares the hell out of me. I don't like the idea of burning a laser into my retinas while I'm awake and then go blind within the next 15 or so minutes hoping that my sight would return.

Thanks a bunch!

Hi deep_6,

I know you didn't ask about Lasik and I'm not trying to push my thoughts on you but if you ever want to discuss Lasik I would be glad to chat with you. I did a lot of research before making the decision to go ahead with it 4 years ago. The results have been wonderful. My vision was 20/2000 (no, not 20/200, it was 20/2000) and -9 diopters with astigmastism in both eyes. I had to stand 3 feet from the eye chart to be able to make out the big E on top. Not to see it clearly, but just to be able to make it out. To read my watch without my glasses I had literally had to bring the watch to within about six inches of my eyes.

Anyway, if you ever want to chat about Lasik I would be glad to share my experiences with you.

Take Care,
Mark
 
My thanks to EricDive, Aeolus, Dwain, frankenmuth_tom, and fins for your very helpfull informative and encouraging posts.

Right now I'm leaning towards the direction of wearing a mask (regular or hydroptics) but have yet to determine what kind.

LASIK is still out of the question at this time due to cost. Like what I said in an earlier post I'd rather spend on gear and dive half blind.

Thank you all.
 
Hi all. I'm getting stock corrective lenses for a snorkeling mask. I am nearsighted with some astigmatism. The question is how many diopters to get.

One web site http://www.snorkel-mart.com/c171377.2.html says to take the sphere (the first number in my prescription, representing nearsightedness) and add to that half of the cylinder (the second number, representing astigmatism) to compute the effective spherical correction. Is this correct?

Another site http://www.freediver.net/freedivelist/faqstuff/faq_masks.html advises to subtract 0.50 diopters to compensate for the distance from my eyes to the lenses and for the refractive properties of water.

On the other hand, because I am a multifocal lens wearer, maybe I should add a little plus correction to compensate, since the objects I will be looking at are not too far away.

Thanks to anybody who can help!
 
Unless the online lenses are [strong]really[/strong] cheap, you should probably just send your mask and prescription to an optician that does a lot of this.

There are a bunch of variables that need to be considered, including the distance from your eyes to the mask, placement of the lenses, the refractive index of water and the distances you need to see (gauges, far away stuff, etc.)

If you only need them for close up, you can buy very thin plastic stick-on lenses that make your mask sort-of bifocals. These sound really cheesy, but work well.

If you need to see far away, you might like contacts better, since putting lenses in your mask decreases the field of vision significantly.
