Which mechanism enabled Ibn al-Haytham to accurately model imaging within the human eye around 1000 AD?

💡 Explanation

Ibn al-Haytham modeled vision by tracing light rays from object points through the eye to the visual cortex, treating the lens as a single refracting surface because this simplified the complex corneal and lens curvatures involved. Therefore a simplified refractive surface modeling of lens resulted, eliminating need for more precise surface mapping or simulating lens imperfections.
