Area of Science:
- Ophthalmology
- Public Health
- Epidemiology
Background:
- Spectacle correction is crucial for visual acuity.
- Understanding spectacle needs is vital for public health initiatives.
Purpose of the Study:
- To determine the prevalence of met and unmet spectacle needs in Tehran.
- To identify factors associated with uncorrected refractive errors.
Main Methods:
- Random cluster sampling of 6497 Tehran citizens.
- Ophthalmic examination and interviews conducted.
- Analysis of refraction data for 4353 participants aged 5+.
Main Results:
- Spectacle need was 14.1%; met need was 9.3%, unmet need was 4.8%.
- Spectacle coverage rate was 66.0%.
- Older age, lower education, and myopia were linked to unmet need.
Conclusions:
- Identified significant unmet need for spectacles in Tehran.
- Highlighted high-risk groups for targeted interventions.
- Recommended further research into causes of unmet need.
