Well I have put a short course out now for parents and teachers on vision and visual processing in education on Udemy.

They have put it at a low price to encourage uptake.

if you wish to see a bit of what is on it free - there is a preview at the start, it may make you interested in the subject,

I am putting another course out on it free this month, about what an optical professional can do with filters, for optical professionals as well as the public.

I hope you find it interesting
