The study provides evidence that p-EVES devices can play a useful role in supplementing the range of low vision aids used to reduce activity limitation for near vision tasks.

The evidence base in low vision rehabilitation is modest and further high quality clinical trials are required to inform decisions on healthcare provision. The p-EVES study findings are anticipated to contribute to this broader evidence requirement, with the methodological issues evident here being relevant to other trials within the field.

Rachel Bambrick, Professor Christine Dickinson, John Taylor and Dr Robert Harper discuss the portable electronic vision enhancement systems study and explain its implications for those aiming to prescribe magnification for close work.
