About this trial

The goal of this clinical study is to evaluate how adults aged 18 to 65 move their bodies and eyes when they use screens, with various eyeglasses. The main questions it aims to answer are :

* How the behaviour between young and presbyopes is different while performing visual tasks on digital devices ? * How the behaviour while performing visual tasks changes according to different types of eyeglasses ? Participants will be asked to take part in an eye exam and do simple visual tasks on digital devices.
