Abstract  The human eye lens is sensitive to radiation. Thus, detailed eye models are needed to accurately assess the dose and radiation risk for the eye lens. A detailed eye model was build based on the characteristic parameters of Chinese adult males. The eye model includes nine main structures for the eyelids, scleral, choroid, retina, lens, iris, cornea, vitreous body and aqueous humor. The model was then used in an MCNP code to calculated the eye lens absorbed dose conversion coefficients for electrons for various irradiation conditions. The results compared with other studies show that the relatively deep anterior chamber of the Chinese male eye results in significant differences in the absorbed dose for electron energies between 0.6-1.2 MeV with a maximum relative difference of 98%. The detailed eye model in this paper provides a tool for accurate assessments of eye lens doses of Chinese adult males.
