U.S., July 2 -- ClinicalTrials.gov registry received information related to the study (NCT07679048) titled 'Measuring How Quickly the Eye Focuses After Sustained Viewing of Close-up Images and Videos' on June 25.
Brief Summary: In this experiment, subjects will view a cross pattern on the screen and be asked to focus their eyes on it. The cross pattern will look like it is moving towards and away from the eye in a back-and-forth motion. As the subjects focus their eyes on the shapes, we will measure the focus of their eyes using a device called a wavefront sensor. This device uses infrared light to measure the optical properties of the eye in real time. Our goal is to find out how well the eye focuses before and after viewing images on a s...
