Research

Peek approaches all of its work using rigorous scientific and public health methods.  We determine the greatest needs and barriers to change then trial and test solutions to ensure we are effectively reducing them.

Peek began life as a project at the International Centre for Eye Health (ICEH), a research and education group based at the London School of Hygiene & Tropical Medicine (LSHTM). Since spinning out from LSHTM in 2015, Peek continues to work closely with ICEH and other groups on research, teaching and dissemination of information.  

Peek tools are clinically validated and backed by numerous peer-reviewed research studies.  Our software, programme design tools and data insights are in use in schools and communities across Africa and Asia, and we are working with partners to introduce our tools to new countries every year.

Peek Acuity, our vision check app, is embedded into our software for eye health surveys and school and community eye health programmes.  Research published in JAMA Ophthalmology in 2015 shows that Peek Acuity is at least as accurate as conventional distance vision checks when used by non-specialist community health workers in Kenya.

A school eye health programme in Kenya powered by Peek was evaluated in a randomised controlled trial comparing it to a conventional school eye health programme, published in The Lancet Global Health in 2018.  The results show that more than double the proportion of children attended follow-up appointments with Peek.  

Another randomised controlled trial in Kenya compared a community eye health programme powered by Peek to a conventional programme.  Published in The Lancet Digital Health in 2020, the study showed that with Peek, almost three times the number of people with eye problems were connected to care compared to conventional programmes. 

Other research has helped refine our approach and inform future product developments and our team members regularly publish in peer-reviewed journalsPeek team members have contributed to reviews of the economic impact of vision loss, Rapid Assessment of Avoidable Blindness (RAAB) eye health surveys and The Lancet Global Health Commission on Global Eye Health.

36 million people worldwide are blind.  Four in five of them could keep their sight with simple surgery or treatment.  Millions more can't see clearly, yet need no more than a simple pair of glasses.  We won't stop until everyone has been linked to the treatment and services they need.
