Color of visual display terminals and the eye. Green VDTs provide the optimal stimulus to accommodation.
The longitudinal chromatic aberration of the human eye is substantial and therefore the color of the phosphor chosen for a visual display terminal (VDT) will affect refractive state and accommodative demand. For most working distances, green stimuli (lambda max 520 nm) are optimal.
