variable focal length
i have an idea!
the problem of eye strain is due to continuous gazing at a fixed point (say computer screen). the point at the which the electrons emitted from the gun is fixed. if i keep it changing continuously, the focus point of the eye lens varies and the strain reduces.
the problem here is the screen, which has the flourescent material at the back is fixed, if i vary the electron speed, i have to change the distance of the screen accordingly. how is it possible. is there any other way. suggest.
thanks
