“…Similarly, literate adults would be more willing to get near corrections as reading and execution of other near vision related tasks become difficult. While some previous studies have found gender as a determinant of met presbyopic needs, 18,25,26 our study did not find that. This could be due to our study location being predominantly urban, compared to the other studies which were conducted in rural settlements, where cultural factors such as unequal access to eye care by males and females, markedly influence the gender difference in met presbyopic need.…”

“…This could be due to our study location being predominantly urban, compared to the other studies which were conducted in rural settlements, where cultural factors such as unequal access to eye care by males and females, markedly influence the gender difference in met presbyopic need. 26 The majority of those who had a near vision spectacle correction had obtained them from an eye care centre. This is a positive finding as they may have been seen by a qualified eye care professional, and may have had a comprehensive eye examination, compared to those who may have obtained their correction from a wayside vendor for example.…”

Abstract:Purpose: To determine the near vision spectacle coverage and barriers to obtaining near vision correction among adults aged 35 years and older in the Cape Coast Metropolis of Ghana. Methods: A population-based cross-sectional study design was adopted and 500 out of 576 participants aged 35 years and older were examined from 12 randomly selected clusters in Cape Coast, Ghana. All participants underwent a comprehensive eye examination which included: distance and near visual acuities measurements and external and internal ocular health assessments. Distance and near refractions were performed using subjective refraction technique. Information on participants' demographics, near vision correction status, near visual needs and barriers to acquiring near vision correction were obtained through a questionnaire administered as part of the study. Results: The mean age of participants was 52.3±10.3 years of whom 280 (56%) were females and 220 (44%) were males. The near vision spectacle coverage was 25%, 33% "met need" for near vision correction in the presbyopic population, and 64% unmet need in the entire study population. After controlling for other variables, age (5 th and 6 th decades) and educational level were associated with "met need" for near vision correction (OR=2.7 (1.55-4.68), p =0.00, and OR=2.36 (1.18-4.72), p=0.02 respectively). Among those who needed but did not have near vision correction, 64 (26%) did not feel the need for correction, 55 (22%) stated that they were unaware of available interventions, and 53 (21%) found the cost of near vision correction prohibitive. Conclusion: There was a low near vision spectacle coverage in this population which suggests the need for strategies on health education and promotion to address the lack of awareness of spectacle need and cost of services.

“…The spectacle coverage of 38.0% in the current study is higher than presbyopia correction coverage obtained in a previous study conducted in a rural community in Enugu, south-east of Nigeria which found presbyopic spectacle coverage of 27.8% [14]. Another study in a rural community in Abuja found a presbyopia correction coverage of 21%, [22] whereas a similar study in a rural population in Zamfara state, north-western Nigeria revealed a presbyopia correction coverage of only 0.7% [20]. A possible explanation for this discrepancy is that unlike the current study, the previous studies cited were all conducted in rural communities where it may be unlikely to find any form of eye care services.…”

Aim: To determine the magnitude of presbyopia and the effect of uncorrected presbyopia on vision-related quality of life in Calabar South, Nigeria. Study Design: A community-based, descriptive cross-sectional study. Place and Duration of Study: Calabar South Local Government Area, Nigeria, between November 2016 and February 2017. Methods: We included 422 adults (198 men, 224 women) aged 35 years and above, selected by cluster random sampling. Subjective distance refraction was done on all participants with distant visual acuity less than 6/6. Near visual acuity was assessed at 40 centimetres with a Times Roman near vision (British N system) chart, with distant correction in place if required. Presbyopia was defined as inability to read N8 at 40 centimetres unaided or with habitually worn distance refractive correction, with improvement of near vision by at least one line on a Times Roman near vision chart with use of a plus lens. An adapted and validated quality of life questionnaires were administered to the participants. Results: A total of 422 participants were examined and interviewed. The prevalence of presbyopia was 55.5%. There was no significant association between gender and prevalence of presbyopia. The presbyopia correction coverage in the study population was 38.0% with a strong positive correlation between age and the required near vision spectacle lens power (r = 0.88, p < .001). Another key finding was a significant association between uncorrected presbyopia and reduced quality of life. Conclusion: This study has demonstrated that the burden of presbyopia in the study population is enormous in spite of the fact that it has a cost effective intervention. The key findings in this study underscore the need to scale up presbyopic correction services in the study area.

“…It is possible, however, to remove hypothetical bias by a follow-up certainty question, which may result in realistic WTP [12]. While 13 studies in this scoping review were conducted in similar hypothetical conditions most did not report this shortcoming while others explicitly stated the overestimation and underestimation of WTP [28,33,34,45,50]. It is thus unclear whether these flaws were observed in any of the included studies.…”

“…Regarding sampling methods the majority of studies used probability sampling which comprised of simple random sampling [28,30,35], systematic sampling [26,27] and cluster sampling [32,33,36,45]. All are advantageous as simple random sampling is usually representative s of the general population, systematic sampling spreads the sample evenly over the population and cluster sampling is economical and feasible for larger populations [46].…”

Background The global recognition of uncorrected refractive error as the main cause of vision impairment has increasingly demand for affordable, available and accessible refraction and spectacle dispensing services. Willingness to pay (WTP) for spectacles studies afford context-specific planning for integration of these services into eye care service delivery. The aim of this scoping review was to identify the rationales and the range of methods used when conducting WTP for spectacles studies. Methods We undertook this scoping review, using a search from EBSCO (host), Medline, PubMed, SCOPUS, Google Scholar and ProQuest databases. We also searched Google and eyecare organisation’s websites for grey literature. We analysed the articles using the scoping review methodological framework proposed by Arskey and Marley. Results The search identified 237 from and only 14 were eligible. 79% (n=11) were published articles and 21% (n=3) were grey literature. All studies were from developing countries. Most of the studies reported rationales with a few that were vague. The majority of the studies used survey-based techniques, where the limitation and strengths were reported. Conclusion The scoping review highlighted the knowledge gap in reporting the WTP for spectacles methodologies that need to be considered in reporting future research. Keywords: Willingness to pay, spectacles, eyeglasses
