A Unified Formula for Light-adapted Pupil Size with Interactive Demonstrations

Andrew Watson of the Ames Research Center reviews seven published formulas and proposes a new unified formula for pupil size. The formula incorporates the effects of luminance, adapting field size, observer age, and monocular or binocular adaptation. The work includes interactive demonstrations and software implementations.

Use Cases

• Modeling visual performance based on pupil size dependencies described in the formula
• Simulating human visual system adaptation for display and lighting design based on luminance and field size parameters
• Developing age-adjusted vision models based on the age factor incorporated in the unified formula
• Comparing monocular and binocular adaptation effects in vision research based on the formula's parameters

Strengths

• Formula is derived from a review of seven published historical formulas
• Incorporates multiple modulating factors: luminance, adapting field size, observer age, and monocular/binocular adaptation
• Includes interactive demonstrations and software implementations for practical use

Limitations

• Row count and column-level documentation are absent; data structure must be inferred after download
