简要总结
This study examines how myopia (nearsightedness) and hyperopia (farsightedness) affect the use of progressive addition lenses (PALs) for computer users. PALs offer a range of vision correction within one lens, ideal for presbyopia (age-related near focusing difficulty). We'll compare visual comfort, eye strain, and user preference for PALs between myopic and hyperopic individuals while focusing on computer screens.
详细描述
The research will also consider if general-purpose PALs differ from computer-specific PALs in these user groups, and how presbyopia progression might influence PAL effectiveness for each condition. This information can help eye doctors recommend the most suitable PAL design for computer users with myopia or hyperopia.

结局指标
主要结局
Visual Acuity
时间窗: 12 Months
Assessing visual acuity at different distances, including distance vision (for activities such as viewing the computer screen) and near vision (for reading text on the screen), while wearing progressive addition lenses.
Subjective Visual Comfort
时间窗: 12 months
Using standardized questionnaires or subjective ratings from participants to assess their comfort level while using computers with progressive addition lenses.
Visual Fatigue
时间窗: 12 months
Assessing the level of visual fatigue experienced by participants during or after prolonged computer use with the progressive addition lenses. This could involve subjective ratings of eye strain, tiredness, or discomfort.
