Hey! always good to meet another Israeli on board!

Any chance you're Dan from Siam? :)
We probably know some of the same people, but not all of them.

OceanMan, we'll start gathering some people. I hope the cost is indeed 6euro per package. Do you know what kind of mail is that> (as in how fast it'll get here)

Have you told the people ordering that there is only a 10% chance that their lenses will result in working goggles?

It is much harder than it seems. In the past many people ordered 'just lenses' from me and I warned every one of them. In the end about 1/10 actually managed to make working goggles.

Fine for people to make a group order, but make sure they know what they are getting into.

Did you tell them that they need to spend 3 hours trying to scratch out the anti-fog coating inside their swim goggles, to make the glue stick? And that in doing that there is a 75% chance the goggle will be ruined?

It seems that several people here have managed to build their own fluid goggle with success. So nothing impossible.

DeepThough I will get some information about the post/mail and I let you know.

It's not impossible to make your own goggles, but it is much harder than it seems.

When people would order lenses from me, I would warn them that it was a hard process.

Most people would eventually complain later, saying that their goggles 'didn't work' and they wanted their money back for the lenses. But, it wasn't my fault since I warned them in the first place.

That's why I stopped selling just the lenses!

I'm curious, is it the cost of the fluid googles that is making most of the people on this thread want to make their own fluid goggles, or is it the challenge of making them. $165.00 US isn't all that much to spend on a piece of equipment for freediving. When I look at the cost of suits,or fins (bi fins or mono fins) for freediving, I find it hard to believe that someone would be that hard pressed to put the money out for something like fluid goggles.

Hardhat, you may find it hard to believe but 165$ for some of us it is a lot of money.
I'm a poor student. There's a '-' infront of a nice sum of money in my bank account. The situation is the same for many of my student friends. In some countries the earning/expenses ratio is not as good as in the US. I even canceled on a mono I was fantasizing of that costs about the same sum of money. I'm freediving with 3y/o plastic fins.
My estimates are that no matter how hard I'll work (which I don't really at this exact moment, though it'll change in 2 weeks) I won't be able to go through university without any support from my parents. That's the same for 100% of my student friends.
Among the list of Israeli freedivers who will join this order, beside students there are also teenagers.

Considering that fluid goggles rank pretty low on the essentials for diving (for most of us atleast), somewhere after weights and even a nose clip (which I'll probably do my own as well), many can't justify that expense.

(and yes, there's always something nice in the DIY challange)

Eric, thank you for sharing your difficulties (and inventing the goggles!!).

I am aware of (some of) the risks of trying to make them my own.
With the cost of a little more than a cheap meal I am willing to take that risk as it's the only chance I'll get to have fluid goggles in the next few years.
I have a few old swimming goggles laying around that won't be of any loss if the attempt would fail.

I was thinking of attatching the lenses to the sides of the goggles through some plastic extender rather than to the goggles' lenses themselves.
Making holes in goggle's lenses and puting the fluid lneses inside is also an option (if allignment seems to work).
Last option is to put them in any round frame (a cross section of a pipe for example) with a band to wear them. Will be Crude and uncomfertable, the rather salty water of the red-sea will sting more than I intended, but it should work. I've seen this last version made by Bevan.

4.62€ per pair?
How much would it be a total cost with shipment to Croatia...
If it's now too much count me in for one pair (I'll ask if anyone else is interested)!

I went ahead Ignoring all the "this is a specialist thing" "you cant make them" Dont waste your money" and I made some! There was NO anti fog coating that took three hours to scrape off with an accurately calculated 75% risk of ruining the goggles.

My goggles work and they look great and they are on the earlier pages of this thread.

My advice is if you want to try, Go for it! use your inventive nature and build something. lets face it, its the joy of making something for yourself that you can use that counts

Get stuff free or make stuff Dont feed the machine!!!

What if some of us from the States got in on your order?

If you could ship them here, reasonably, I think we could round up the rest of the needed 100 minimum order.

Im definetly interested in about 5 sets in the 100 for Sydney Australia if we can work out payment and postage.
It would be great if everyone could post some pics of their creations and say how they affixed the lenses in place and what brand of goggles used .

Cheers Nathan Watts

Ok guys it is now a world command and not only a European command. If I can ship the lenses to Finland or Israel why not to Australia or USA ? Let's go for it. The cost of shipment from France to Australia or USA or else is not that much, depending on the weight. For 0,1 Kg = 100 g the maximum price is 2,85 € ; for 200 g it is ~8 € . I don't know exactly the weight of lenses.

If you are interested please send me a private message with your email so I can create a mailing list with those who want to buy lenses. Then we will be able to organize the command.

I have sent you a private message.

We are closer and closer to the 100 lenses if we haven't reach it yet. Please feel free to contact me to join the command.

Re: DIY Fluid Goggles - Silly Question

Okay, this might be a dumb question by someone with little understanding of optics, but here it is.

When making fluid goggles why are we using PCX lenses, which stands for Plano Convex Lenses and, which means to use them for magnification we have to look through from flat side and convex side is against the inside of the goggle lense, which means we have to build stands off and fool around with mounting them, etc.; when we could use PCV (Plano Concave) lenses and just glue the flat side to the goggle lenses with some non-yellowing optical glue like the optical shops do for prescription dive masks?

Maybe I found the answer to my own question. I saw these statements on an optical web site:

“Plano-Convex Lenses (PCX) have one flat and one outward curved face and a positive focal length. They can magnify or condense.”

“Plan-concave lenses (PCV) have one flat side and one inward curved face and a negative focal length. The are use for image reduction or to spread light”

So if I understand it, if you look through the inward curved side of a PCV lense you get image reduction, but from the other direction they are made to spread light, not magnify sight. You probably only see blurry enlargement with lots of light.

PCX lenses can be used for image magnification or reduction based on which way you look through them.

But I wonder if the gluing idea could still work by doing what bevan dewar did on page three of this thread and attach the PCX lense to the outside of goggle lense, but instead of trying to use hold offs to allow water between the two lenses and then have to deal with air bubbles and cleaning issues, just glue them together with no air space.

One major problem is the small diameter of the lenses, 20mm. When you go up in diameter of pre-manufactured lenses the focal point goes way past 20mm.

The cost of one (1) Hiteck lens is 4,62$ according to their website.

I've been waiting for someone else to answer you. Optics is not my best subject.

Concave lenses will make focuse worse.

"PCX lenses can be used for image magnification or reduction based on which way you look through them."

It doesn't care which way you look through them, they act the same. The flat side allows you to mount them inside or outside the goggles. If you mount them inside, you will be able to see in and out of the water (if the goggles are filled with saline solution). On the outside, you can't see until you're face is submerged.
