Overview

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.

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.

Interventions

MyopiaBEHAVIORAL

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.

HypermetropiaOTHER

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.

Outcomes

Primary Outcomes

Visual Acuity

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.

Time frame: 12 Months

Subjective Visual Comfort

Using standardized questionnaires or subjective ratings from participants to assess their comfort level while using computers with progressive addition lenses.

Time frame: 12 months

Visual Fatigue

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.

Time frame: 12 months
