A system for performing measurements of an eye comprises: a measurement toolforperforming measurements of the eye, the measurement tool including anobjectiveand implementing an image capturing function using the objective； at least onerestdesigned to maintain a facial measurement position, the at least one restdefining acentering rest portion designed to maintain a lateral facial measurementposition； anadjuster mechanism adapted to move the objective relative to the eye； and aprocessingunit configured to control the system to: position, via the adjuster mechanismand for a first eye, the objective at a predefined first pre-scan position；scan,via the adjuster mechanism, the objective away from the first pre-scanposition untilthe system detects a pupil of the first eye； and trigger one or moremeasurements ofthe first eye via the measurement tool dependent on the system detecting thepupilof the first eye.
