Official title
Modèle de Performance Subjective Généralisé
Overview
This clinical study wants to understand how blurred images look to young adults. The main question is: How do different kinds of images and different kinds of blur change the way people think those images look? Participants will get an eye exam, then look at several blurred images and rate how good or bad each one looks on a quality scale from 1 (very bad) to 10 (very good).
Interventions
- Device eye exam
participants will follow a complete eye exam - Other image rating
participants will have to rate the perceived quality of images on a 10 points scale
Primary outcome measures
- Subjective image quality rating on a quality scale from 1 (very bad) to 10 (very good) [Time frame: Day one]
Eligibility criteria
