In this study, the researchers will be using eye tracking and detailed lighting measurements to understand how different types of indoor and outdoor lighting affect the eye movements and pupil sizes of our participants. Participants will be paired up and undergo six eye tracking sessions, split across two appointments. Each appointment will involve viewing either indoor or outdoor scenes, and before each session, participants will spend time adapting to the lighting conditions. Overall, each participant will spend 24 minutes being tracked, and the entire study will take about 2-3 hours to complete. The investigators expect differences in eye movements and pupil size between indoor and outdoor scenes.

All participants will be exposed to the same environmental conditions (same indoor and outdoor scenes for the same duration) and the captured eye-movement data of every participant will be of the same type. Participants will be exposed to different orders of scene sequences.
