Technical information about lenses

[Oculus_OD]

Hi @,

I'm looking for a website/database where I can search for technical information about specific lenses of the most common lens manufacturers.
The question I've is for example:

- lens freeform of conventional.
- What kind of freeform? (Trueform, back-curve freeform) etc. etc.

Thank you.

Hi,

Well I would suggest you that research a lot and find relevant information about specific lenses. As there are various eye test clinic available, just consult with the doctor and get it done for you.

I agree with sylviaandrew. I think you should consult with the doctor to get all the technical information related to lenses.

Oculus, sadly there is no list or database of different lenses or technical information. Only a few companies offer this information at all anymore without large amounts of Scotch and NDA's involved, and some won't even give it to their own sales reps. With one recent lens question I had to go the VP products before I got the answer I wanted.

I have had to result to blackmail, bribery, and even.... gasp.... talking to engineers. I even had to figure out away to map free-form lenses on my own which was both time consuming and expensive. Optiboard remains the best source of readily available info without resorting to expensive Single Malt Scotch or an AR Dual Lens Mapper. (not at the same time of course, friends don't let friends drink and map lenses).

Out of curiosity, Did you or anyone publish their results from lens mapping? I wish there was a cheep way to see them.

Try www.thelensguru.com the site is by subscription but it gives all the details you need.

Tony the site owner breaks it down by surface side and categorizes to molded, digital mold, and digitally surfaced. That way can tell a traditional grinder from all the other variations. He also includes base curves, insets, fitting cross above set, recommended RX ranges, adds, and material availability. I have found the information to be thorough and accurate. The subscription is peanuts and when you compare it to a lenses subscription from framesdata your definitely better off. I think the site has a two week trial so you don't have to take my word for it.

Better to consult with the doctor about technical specification of lenses. Do a lot of research on Internet and find best source for yourself.

Yes, a doctor of mathematics, with a strong background in differential geometry, physical and visual optics. Read their patents and white paper(s), and wear their lenses.
