I have now completed and had published 260 page book on tint prescribing and dispensing, got a video tint course ready (10 hrs approx) both in English and Russian. There is a lot new for optometrists and opticians - and some of the videos are spectacular.
My thoughts are that I would give the video course away with the book for private individuals but would charge a license for colleges / universities if they wanted to use info.
Cost of book is around $70 + postage in English (arrangements are different in Russian - course is already available).

Is this a good model or should I do it differently for USA / rest of world.

Book already available in UK - contact me for retailers - it has been described as "brilliant" by probably the most knowledgeable person in UK optics!
