As for photographic systems , the human visual system can also be described by an MTF. However, due to the complexity and non-linearity of the visual system, the MTF alone is a poor predictor of response. We have formulated and tested two mathematical models which modify the MTF of the eye. Effectively, an imperfect integrating function (low pass filter) has been proposed to be operating on stimuli which are sent to the brain. The models were tested and found to be better predictors of visual response than the present MTF alone.
