Numerous eye gaze changes of different fixation viewings are involved in driving. In addition, driving is done under various surrounding illuminance conditions. However, the effect of different illuminance transmissions on eye gaze movement was not explored during driving. This study investigated the saccadic eye movement using eye tracking system under different illuminance transmissions during driving simulation. The investigation was conducted on twenty-eight participants aged between 21 to 26 years old with proper driving licensing and experience. All participants had good vision status, with a good history of systemic, ocular, and binocular vision health. Using driving simulation, the participants were instructed to drive as they usually did, and their saccadic eye movement was recorded via the Dikablis eye tracker. The surrounding illuminance within the experimental room provided 100% transmission of 500 Lux, and the illuminance transmission was varied to 50%, 30%, and 15% using neural density filters. Under different illuminance transmissions, the saccadic eye movement showed no significant differences (p>0.05), even with the 15% transmission, both in the number and duration of saccadic eye movement. This showed similar eye gaze change specifically saccadic movement during driving simulation with different light transmissions. It could be concluded that eye gaze movement was not influenced by reduced illuminance when driving.
