About

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.

Full description

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.
