Lets hope we get a critical mass of people to get this sorted. On a related note, does anybody know where the CAA (or the law for that matter) stands on the use of colour vision 'correcting' contact lenses (ChromaGen and the like)? I asked the question a couple of years ago after failing the HW lantern test at Gatwick and was told (suprise suprise) that they were not permitted to be used in any tests. This leads to another intersting legal angle for us. If you are permitted to use ordinary eyesight correcting contact lenses (up to a maximum prescription), then why not colour vision correcting lenses? Both result in the test being passed (hopefully!) so, by the CAA's own definition, both cases are fit to fly. Anybody have any experience of using these lenses in a medical?
