Visual function, digital behavior and the vision performance index.

摘要: Historically, visual acuity has been the benchmark for function. It is used to measure therapeutic outcomes vision-related services, products and interventions. Quantitative measurement of suboptimal can potentially be corrected optically with proper refraction in some cases, but many cases reduced vision there something else more serious that impact other aspects function such as contrast sensitivity, color discrimination, peripheral field view higher-order processing. The typically requires stimuli subject degree standardization or calibration thus often limited clinical settings. However, we are spending increasing amounts time interacting devices present high-resolution, full images video (hereafter, digital media) record our responses. Most these function, not just targeted testing experiences from typical device interactions. There growing evidence prolonged exposure media lead various issues (eg, computer syndrome, dry eye, etc.). Our regular, daily interactions (digital behavior) also assess passively continuously. This allows us expand health assessment beyond clinic, collect data whole range settings behavior practically any population(s) interest further explore how increasingly virtual affecting vision. We a tool easily integrated into provide insights behavior.
