What file do you recover?The instructables should help in explaining the project to you!
Yes, I think so too!
Thanks for your comments and appreciation and of course the votes!!!Much appreciated :-)
Thank you for the comment and the warning. I will have to test it for a longer period of time to know if salt water does anything to it. However, in my case the lens is encased in an airtight compartment that is made of acrylic so the lens does not come into direct contact with the salt water. Acrylic also is known to be resistant to salt water. But in any case I will have to observe if any problems show up in time. Thanks and cheers!
Thank you for taking the time to comment and appreciate!:-)
Thanks for the information! Will let you know of there are any problems as I'm using acrylic.
This article should help explain some of the physics:http://www.askamathematician.com/2010/10/q-why-is-our-vision-blurred-underwater/
I actually experimented with my corrective lenses (+1.75) and also a 10X magnifying glass immersed directly underwater and I just couldn't get a focused magnification. I then found someone on the internet (http://www.seaslugforum.net/find/526) who recommended encasing a magnifying glass in a sealed container with air. I used the same principle for my corrective lenses and it worked. I am not very clear about the physics behind it but "intuitively" it sounded correct. I later added more power (+0.50) to my corrective lens to get the optimal correction underwater.
Thank you for the suggestion and information. I didn't know that the refractive index of lenses could be easily changed and that such lenses were that affordable. I was under the impression that making such specialized lenses would be expensive and one of the objectives of my project was to make it affordable. I will now explore your suggestion. Thanks again!
Oh... my bad... I missed the joke.. Shows I don't go to the oculist often enough :-)Cheers
Thank you for the appreciation!I am keen to see if someone from the industry, i.e. a dive mask manufacturer, can incorporate a similar concept in their masks. It would be more compact.Happy diving!
Both are equally functional but the the "2" improved version, is much more convenient to use. However it requires more 3D modeling skills and a bit more work.

Thanks for the appreciation! :-)Yes indeed this is also an alternative to using contact lenses while scuba diving. You should try it.
