Constructing a human eye model: The cornea shape effect on optical imaging for the human eyes

This paper study the effect of cornea shape on optical imaging of the human eyes for future constructing a human eye model using ray tracing method in optical design software Zemax. Theoretical calculation results show that geometric image is best when the cornea's front surface radius being 7.8mm and gets bad away from 7.8mm. When the cornea's front surface radius is 7.8±0.015mm, the image can't be recognized. Further, calculation RMS radius shows the radius is smallest when the cornea's front surface radius being 7.8mm and gets big when away from 7.8mm.
