light - What causes a selective shift of colour perception after removing wavelength filtered glasses?

Background

To improve sleep by reducing blue-light melatonin disruption, I wear night-glasses that filter short wavelengths (e.g. something like these). With these glasses on, both the top and bottom bars of this test image will appear visually identical:

But the colour spectrum you "see" while filtering the blue light will not appear to be either of these bars; instead some partially de-saturated hybrid of the two. I think this is probably due to a pervasive blue wavelength of the LCD back-light regardless of defined colour contrast.

However, there is something else odd going on. If I wear these glasses for several hours and then remove them for some reason - all the blue colours I should see will be muted, partially de-saturated or even interpreted as a shade of green for at least several minutes afterwards (I haven't stop-watched the effect). Freaky.

Question

Why is this selective shift of colour perception occurring for a while after removing wavelength filtered glasses?
