Summary
Viewing 3-D displays causes eyestrain, particularly for those wearing contact lenses or no correction. Spectacles offer better visual comfort during stereoscopic viewing.
Area of Science:
- Ophthalmology
- Visual Science
- Human-Computer Interaction
Context:
- 3-D displays are increasingly common.
- Assessing visual comfort is crucial for user experience.
- Parallax barrier systems present unique visual challenges.
Purpose:
- To investigate eyestrain induced by 3-D display viewing.
- To compare visual discomfort across different visual correction methods.
Summary:
- Eyestrain, prolonged accommodation, and delayed relaxation/contraction times were observed after 15 minutes of 3-D viewing.
- Uncorrected subjects and those with soft contact lenses (SCL) showed significant changes.
- Hard contact lenses (HCL) also induced delays, while spectacles did not significantly alter accommodation or subjective symptoms like "clouding" and "eye dryness".
Impact:
- 3-D display use may exacerbate eyestrain in individuals with specific visual corrections.
- Spectacles appear to mitigate some adverse effects of 3-D viewing.
- Findings inform the design and use of 3-D displays for visual comfort.
