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

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

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.

Inclusion Criteria:

• The age of Participant will be 40 to 55 years
• Participant diagnosed with myopia having -0.50 to -3.00DS and astigmatism up to -0.75DC
• Patient diagnosed with Hypermetropia having +050 to +3.00 DS and Astigmatism up to +0.75DC
• Presbyopia addition will range from +1.00 to +2.50 DS
• Participants who have worked more than 4 hours on the computer screen.
• Participants who will be already progressive users and first-time users.
• Patients with no Ocular disease.

Exclusion Criteria:

• Participants with Pre Presbyopia and above 55 years of age
• Participants with significant ocular disease.
• Participants with uncontrolled diabetes and hypertension
• Participants who will not be willing for PAL,s
• Participants with more than 0.75 astigmatism
• Participants with known allergies and sensitivity.
