Do recycled spectacles meet the refractive needs of a developing country?

PURPOSE: The aim was to compare the power of spectacles donated to a recycled spectacle program to the custom-made spectacle refractive prescriptions dispensed in a developing country. METHODS: Two hundred consecutive prescriptions were audited in an optical dispensary in Timor-Leste, a developing nation. These refractions were compared against measurements of 2,075 wearable donated spectacles. We determined how many of the 200 prescriptions could be matched to a donated spectacle measurement, how many donated spectacles could be tried for each prescription and how long it would take to find the matched spectacles. RESULTS: There were 1,854 donated spectacles identified as being suitable for comparison with the 200 refractive prescriptions. Twenty-nine out of 200 prescriptions (14.5 per cent) were matched to at least one pair of donated spectacles. CONCLUSION: Recycling all spectacles is not cost-effective in a developing country that has the ability to make custom-made spectacles and dispense ready-made spectacles.

Geographical and household variation in health-related quality of life in Hong Kong.

OBJECTIVE: This study investigated individual, household, and area effects in the distribution of mental and physical health scores in Hong Kong. METHOD: Analysis of data from a large representative survey of randomly sampled 29,561 Chinese adults in 2002. Multilevel regression methods were used to model variance in the physical and mental component of the SF-12 at the individual, household and area levels. RESULTS: Little variance in scores occurred at the area level (0.3% for physical health and 2.1% for mental health), whereas substantial variance occurred at the household level (23.2% for physical health and 37.2% for mental health), and individual level (76.5% for physical health and 60.7% for mental health). CONCLUSIONS: Similar to studies conducted in Western countries, these results confirm the importance of individual-, household- and area-level characteristics as important determinants of both mental and physical health. It suggests that area-level characteristics may be more important for mental than physical health.
