Comparison Between Myopia Versus Hypermetropia With Progressive Addition Lenses in Computer Users

Not Applicable

Active, not recruiting

• Conditions: Myopia; Hypermetropia
• Interventions: Behavioral: Myopia; Other: Hypermetropia

• Registration Number: NCT06484257
• Lead Sponsor: Superior University

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.

Primary Outcome Measures

Name	Time	Method
Visual Acuity	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	12 months	Using standardized questionnaires or subjective ratings from participants to assess their comfort level while using computers with progressive addition lenses.
Visual Fatigue	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.
