Abstract—A tool chain is presented which allows an estimation of the danger a laser source can pose to the human eye. It makes use of a ray tracing approach to define the spot positions and diameters within the eye. This information is then used to calculate the temperature and likelihood of damage via Finite Volume Method (FVM) calculations. Therefore a previously developed computer model of the human eye is incorporated which allows to determine the thermal behaviour over time as well as tissue damage. The method is exemplarily demonstrated for a scanning laser device and the influence of the accommodation state on the ocular hazard is pointed out.
