Looking for some amazing item which was discovered lately I found an interesting invention of the last century.
I love to read books in bed the problem was after an hour when my neck or spin was in pain because of uncomfortable position I head during the reading. That's why I cannot read longer than 1.5 hour.
This invention could change it...

It was created in 1936 in England. The prism change  line of sight 90 degree without distortion. So you can lie flat in your bed and read or watch TV without neck-ache. I think is the chance for paralyzed or bedridden people.

It didn't become very popular but it available to buy through the Internet it costs around  150-300zł. 

I'm thinking of buying it.
