This work presents a framework of decision-making for additional monitoring of eye lens dose for radiation workers in reflect to the reduction of the annual dose limit of the eye lens dose. Based on a quantitative scheme to systematically estimate (non-) homogeneity of exposure, the proposed "homogeneity index (HI)" is introduced as a criterion of condition branching for decision making of additional monitoring of eye lens dose.
