Summary
Our study aims to delve into the effects of shifting the focal point of blue light from video or text displayed on a terminal screen forward on the axial length of the eye, ocular blood flow, visual fatigue, and visual function, that is, its relationship with Video Display Terminal (VDT) syndrome and myopia. By examining the decoding ability of the adult subjects' retina to the clarity of the signal, we will attempt to develop a novel, non-invasive strategy to curb the elongation of the eyeball associated with myopia. Concurrently, we will also focus on the pathophysiological mechanisms underlying VDT syndrome and explore its potential link to the progression of myopia, providing new scientific evidence for the prevention and treatment of this ocular condition. This research is expected to provide robust support for addressing the global issue of myopia and the health challenges posed by VDT syndrome. Ultimately, by integrating global eye health issues with the challenges brought about by VDT syndrome, we will propose intervention and prevention strategies, offering new insights for the advancement of ophthalmology and public health sectors, thereby promoting visual acuity and ocular health for the population.

| Type | Name | Description |
|---|---|---|
| BEHAVIORAL | blue light defocus and blue light filtering | Subjects are asked to watch a terminal display device for 50 minutes, featuring texts and videos with different defocusing treatments. Specifically, they will start by watching text for 5 minutes, followed by 40 minutes of video, and then another 5 minutes of text, totaling a visual task duration of 50 minutes. The participants will complete a total of 4 sets of tests in a random order. |
