Corrective optics for myopia (short sight) return the vision to a fully correct state.
However if you have red-green deficient colour vision then this relates to the physiology of the retina and cannot be truly corrected with optics.
One suspects that the optics being offered enhance the light/dark contrast perception of the colours on the test charts, allowing the hidden patterns to be more visible to the colour defective eye.
As it is not clear that that would help you distinguish (for example) an isolated red navigation light from a green one in any real situation, where there is no contrast comparison to help you, it is doubtful that this is a valid corrective technique.
