Relationship Between Accommodation Reaction And Accommodation Stimulus
Relationship Between Accommodation Reaction And Accommodation Stimulus
1.Accommodation Stimulus Quantity
The near target that can induce the accommodation reaction of the eye is called the accommodation stimulus. Because the accommodation amount expected to be generated by the fixation eye must conjugate the macular fovea with the near target in order to see the near target, the reciprocal of the distance between the accommodation stimulus and the axial plane of the main point of the eye (m) is called the accommodation stimulus.
2.Accommodation Reaction Quantity
The actual regulatory impulse caused by the accommodation stimulus of the human eye to the near target is called accommodation reaction.
Whether the accommodation reaction is exactly equal to the accommodation stimulus is one of the labels to measure the accommodation function of the eye
- If accommodation reaction is lower than accommodation stimulus, it is called accommodation lag
If accommodation reaction is higher than accommodation stimulus, it is called accommodation lead.
