Several awards and research grants allowed the project to continue testing and development. In 2014 a validation study was completed in Kenya. The study showed that Peek Acuity, our standalone vision check app, is as accurate as conventional distance vision tests.

Peek begins working with our anchor partner, leading disability INGO, CBM Christian Blind Mission. The first CBM programmes powered by Peek began in Pakistan, aiming to take our evidence base into live programmes for the first time. Several more programmes were launched in multiple countries. By the end of 2019 Peek-powered programmes had reached 66,000 people. During this period, the Peek core team grew from 8 staff in 2018 to 36 people worldwide, united in a mission to bring better vision and health to everyone.

His work includes teaching eye health leaders, conducting research to inform best practices, developing new technologies, raising money and building teams, including co-founding a global vision fund and the award-winning social enterprise, Peek Vision.

Peek provides a smartphone vision-testing app that anyone can use, even in the hardest-to-reach locations. The app is embedded into a powerful system for eye health data capture and analysis. With Peek, eye health programme providers can follow the patient journey from screening to treatment and identify where patients are left behind. Programmes powered by Peek currently reach over a quarter of a million people per month.

Tackling avoidable vision loss requires strengthening of health systems (HSs) in order to achieve universal access to ophthalmic services. This has been a major focus of the global ophthalmic public health community and a key goal of the recent World Health Organization (WHO) global action to improve eye health for everyone over the next 5 years, building on the principles of VISION 2020 [6].

The qualitative study consisted of semistructured interviews with all HCPs (ie, 8) recruited for testing Peek, patients (ie, 40) examined with Peek, and key stakeholders (ie, 4) involved in shaping ophthalmic provision in Kenya and were chosen from the ministry of health, an ophthalmic teaching hospital, and selected nongovernmental organizations (NGOs). All patients underwent visual acuity (VA) testing using Peek at their homes, whereas fundal images were taken at a temporary clinic in that cluster. At this clinic, they also underwent repeat VA and funduscopic examinations using traditional equipment.

To assess the acceptability and usability of Peek, it was deemed important to first understand the context within which it is to be implemented [21-23]. The analysis of the context was therefore carried out through a coding framework proposed by a qualitative review of mobile usability studies, which took into account the environment, user, task, and technology [21]. The themes involved assessing patients' and HCPs' perceptions of (1) ophthalmic service provision; (2) the barriers to seeking and accessing ophthalmic services, that is, environment; (3) HCP role and experience, that is, user; (4) understanding the purpose of Peek, that is, task; and (5) familiarity and views regarding mobile technology.

The Technology Acceptance Model (TAM) and its extension, TAM2, were used as a guide to assess user acceptability of the technology [26-29]. This proposes that acceptability or prediction of use of a technology depends on the attitude toward it, which is a function of ease of use and perceived usefulness. The analysis of perceived usefulness was informed by assessing HCPs' perceptions of the benefits. Several studies to date have looked at the benefits of mHealth, and several frameworks have been proposed for assessing benefits in strengthening health care provision [30]. This analysis has therefore adapted a model based on a combination of four frameworks to appraise the potential benefits of Peek in strengthening eye care delivery. The four main themes of the framework were adapted from the Information Communication Technology for Healthcare Development Model [31]. These are capabilities enhancer, social enabler, opportunity producer, and knowledge generator. The subthemes were based on three other frameworks proposed for guiding assessment of mHealth in strengthening HSs [9,30,32,33]. The components chosen for the framework are also in line with the categories of mHealth initiatives established by the WHO [34].

Interestingly, most patients revealed that they did not see the importance of regular eye checks despite being affected by changes in their vision. Only 4 patients brought up the importance of timely eye checkups as a means of preventing visual deterioration.

Peek was found to be acceptable to patients, all of whom expressed being satisfied with Peek. Moreover, the analysis revealed that contentment with the service was often related to the quality of service provision. Most participants supported the use of Peek because it was perceived to be fast and convenient and to be able to reach a larger population in need, in addition to overcoming the aforementioned barriers. Peek is also deemed to have generated a lot of interest among the communities and is therefore an opportunity for increasing awareness of eye health within the population. Although limited, a handful of studies have shown the value of mHealth initiatives in creating awareness, for instance, in general health, HIV/AIDS, and women's health in low-income countries [34].

The analysis of the usability of Peek based on predefined usability dimensions demonstrated that per HCPs' perceptions, Peek generally fulfills the criteria for all dimensions assessed. These included efficiency, effectiveness, learnability, and operability and flexibility. In addition to the usability of Peek, the analysis confirms that Peek is acceptable to HCPs. This was demonstrated by their perceived ability to use Peek easily, fulfill their role, and meet the challenges of ophthalmic provision.

An analysis of the views of HCPs and stakeholders using a model adapted from relevant literature showed the value of Peek in strengthening the HS's ability to provide eye services [30-33]. Peek was perceived to be a capabilities enhancer for HCPs through the provision of diagnostic and decision support. This has already been introduced as an important feature of mHealth initiatives in supporting HSs as proposed in current literature [9,33]. The possibility of using Peek as a screening tool is also discussed under this theme, and its success is thought to be dependent on being able to prove its accuracy, sensitivity, accessibility, and ability to offer a high standard of service delivery. It is therefore vital that these qualities are satisfied in addition to other criteria required for enrolling a screening service before Peek can be rolled out for this purpose [38]. A qualitative study of the accuracy of the tool has been carried out alongside this qualitative study, which has proven its accuracy, repeatability, and consistency as a vision-testing tool. Another study is also underway to determine its suitability as a screening tool in children at school.

Peek's value in creating opportunities that help in supporting health care delivery was also highlighted. These included offering eye care closer to patients and enabling monitoring and surveillance. Additionally, Peek was deemed to be a social enabler and improved communication between providers themselves as well as with their patients. Another theme highlighted was knowledge creation and development of skills by offering training opportunities. The outlined benefits of Peek show its potential value in supporting CHVs in providing a high standard of care through its inbuilt functions, because these support decision making as well as communicating with qualified ophthalmic professionals who can offer advice remotely. Other studies of mHealth in developing countries have demonstrated the value of MPs in tackling the current barriers to service provision and improving the range and quality of services offered by CHVs [34,39,40]. Moreover, these benefits are likely to play an important role in the near future, with the increasing double burden of disease in Africa where chronic ophthalmic conditions, such as glaucoma, age-related macular degeneration, and diabetic retinopathy, are also likely to become more prevalent. As a consequence, the need for Peek to be offered within a well-coordinated HS that is capable of screening for and managing these conditions as part of secondary prevention efforts is likely to become increasingly essential.

1.1 billion people worldwide live with untreated vision loss; by 2050 this figure is expected to rise to 1.8 billion. Simple, cost-effective treatments exist. But eye health organisations in low and middle income countries work tirelessly with lean resources. Specialists are in short supply. Programme impact data arrives late. Those with unmet needs remain invisible to health systems.

A global study by PwC demonstrated that, for every GBP 1 invested in eye health care, GBP 5 is returned. The Global Commission on Eye Health, and several other corresponding studies have proven that correcting vision significantly improves education outcomes, lifts people out of poverty, makes our cities safer and empowers marginalised communities.

The two most prevalent eye conditions, refractive error and cataracts, can be solved with a simple pair of glasses or a low-cost, quick operation. The investment needed is therefore not in developing new treatment solutions but in innovating the delivery of eye health to ensure every person has access to the treatment they need. Something urgently needs to be done to make the invisible, visible in eye health, and turn the tide of avoidable vision loss. ff782bc1db
