This is an observational prospective study in a cohort of healthy subjects who are enrolled using convenience and snowballing sampling. The aims of the study is to demonstrate the efficacy of using NeuraLight system to capture oculometric data from healthy participants and to validate the data capture of NeuraLight oculometric measurements as compared with a validated eye-tracker system in subjects who meet the inclusion criteria and who provide a signed Informed Consent.

The purpose of the trial is to demonstrate the efficacy of using NeuraLight system to capture oculometric data from healthy participants, and to validate the data capture of NeuraLight oculometric measurements as compared with a validated eye-tracker system. In addition, we also aim to collect oculometric data from healthy participants in order to optimize a regression model which can be used for future prediction of clinical endpoints in various neurological patients at different stages of disease
