Where are Alternate Color Tests

[Pietrantonio]

This is really starting to stress me out! I have no way to find who does alternate color vision testing. I can't seem to pass the psedochromatic plates, so I'm looking for a Farnswerth or anything. Anyone have any ideas? Ive called around, but they hassle me for some reason. Any advice is welcomed.

I don't think Farnsworth is valid anymore - the best places to try for some of the alternates would be a college of optometry, or a military base clinic. Ohio State had all the necessary alternates when i was looking, although I ended up taking and passing the signal light gun test.

The Farnsworth lantern is still valid. We have one in our office and do several each month. You can also call the Regional Flight Surgeon's office. They have a Farnsworth lantern and will do it for you.

The Farnsworth lantern is no longer manufactured but there are some around the country.

The folks at http://www.leftseat.com have a list of Farnsworth lantern owners but I think they charge you for the list.
