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).
Distance refractive error (equivalent sphere) between -7 D and +5 D
Astigmatism below 4D
Minimum corrected visual acuity: 10/10
Aphakic or pseudophakic eye surgery
Reported systemic pathology that affects vision
Medical treatment or taking medications that affect vision
Severe ocular pathology declared, involving a loss of visual field as in glaucoma, a loss of acuity
Single group
