Background: This survey was undertaken in a rural local government area (LGA) where eye care services recently commenced, with no known previous data on blindness or visual impairment.
Aim And Objectives: The aim was to generate evidence for further planning and monitoring of the on-going eye care program. The objectives included determination of the prevalence of blindness and visual impairment, causes of blindness and visual impairment, and assessment of cataract services and barriers to cataract surgery uptake.

Article Synopsis
- Improving the lifetime and reliability of self-powered platforms is essential for practical applications, focusing on creating a battery-less wearable system.
- The designed system-on-chip (SoC) incorporates an ultra-low power (ULP) architecture, non-volatile memory, and efficient radio communication, all aimed at minimizing power consumption.
- With features like an energy harvesting power manager and a cold-boot management system, the SoC allows for extended operation without charging and capability for recovery from power loss.
Uncorrected presbyopia is a major cause of poor near vision in the developing countries. To determine the prevalence and demographic characteristics of presbyopia among adult populations (40 years and above) in a sub-urban population, southwest Nigeria, a population-based cross-sectional study was carried out from April to May 2014. A multi-stage sampling method was used to select eligible respondents.

Method: Ninety pupils aged 9-14 years attending two purposively-selected primary schools were selected by simple random sampling. Using the child-to-parent approach and Snellens 6/60 illiterate E-chart, participants had a three-day knowledge and skill-based training followed by 2 days of community-based vision assessment and referral of those assessed.
