    Area of Science:

    • Ophthalmology
    • Neuroscience
    • Vision Science

    Background:

    • Accommodation is the eye's ability to change focus.
    • Blur is a key factor influencing accommodation.

    Purpose of the Study:

    • To determine if target blur is a sufficient stimulus for accommodation.
    • To investigate the role of blur in open and closed-loop feedback configurations.

    Main Methods:

    • Experiments were conducted using various open and closed-loop feedback setups.
    • Accommodative responses were measured in response to different blur types.

    Main Results:

    • Accommodative responses to target blur were equivalent to responses to defocus blur.
    • Blur was confirmed as a sufficient neurological stimulus for accommodation.

    Conclusions:

    • Blur acts as the primary neurological stimulus for accommodation.
    • The eye's 'hunting' action corrects blur-induced errors and adapts to feedback.
