• Recruitment Status: ACTIVE_NOT_RECRUITING

Brief Summary

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.

Detailed 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.

Study Groups

Myopia

Group Type: ACTIVE_COMPARATOR

Myopia

Intervention Type: BEHAVIORAL

Participants in this arm would receive progressive addition lenses specifically designed to correct myopia. These lenses would typically have a prescription for correcting nearsightedness (myopia) in addition to any other vision corrections needed, such as astigmatism correction and presbyopia. The participants would wear these lenses while using computers according to the study protocol.

Hypermetropia

Group Type: OTHER

Hypermetropia

Intervention Type: OTHER

Participants in this arm would receive progressive addition lenses specifically designed to correct hypermetropia. These lenses would typically have a prescription for correcting farsightedness (hypermetropia) in addition to any other vision corrections needed, such as astigmatism correction and presbyopia. The participants would wear these lenses while using computers according to the study protocol.
