They look interesting, especially to someone like me who needs corrective lenses. I can imagine them to be great in a soaring situation - but how are they in a cockpit ? Reason I ask is the huge difference in light between outside and inside (i.e. instrument panel). I fly with graduated glasses for this reason, but these, of course, are not interchangeable
I went for a medical and was told by my AME that I had to use glasses for flying. Off to the eye specialists and they said no your vision is fine maybe a tiny fraction for poor light reading but hey the AME is the boss.
No way did I want to wear glasses so had the glasses tinted so they looked like sunglasses.
Back to the AME and out comes the book for the colour test "failed" !
But How can I fail as I have had loads of colour tests over the years without a problem.
Then it struck me! Put on blue glasses look at yellow and you will see green etc. I protested. " You have to wear the prescription glasses for the eye tests". was his reply.
That was it " so every pilot wearing sunglasses is colour blind and hence illegal" ?
The Ame stuck to his guns, I had to go and buy a pair of clear glasses resit the test before he would issue my medical.
I was livid as I had to buy a third set of glasses when my eye specialists said I didnt need them anyway and that medical cost me a fortune.
I never used that AME again but beware.
