Comparison Between Myopia Versus Hypermetropia With Progressive Addition Lenses in Computer Users
Sponsor: Superior University
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.

Conditions
Interventions
Myopia
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
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.
