Abstract
To assess the impact of visual aids (glasses) on household income, this research uses a fixed effects model to compare average consumption levels between regions treated and untreated by a donor company, Focus on Vision. Panel data from the Living Standards Measurement Survey over regions within Tanzania are suitable for a fixed effects design. However, it is likely that the combination of small samples within regions and the limited (relative to population) donations from Focus on Vision are insufficient in size to capture the causal effects. This research provides solid theory, methodology, and modeling to reveal the causal effect of visual aid on income. Moving forward, the inconclusiveness of the results can be improved upon with an experimental approach and gathering more individual-level panel data.
