The study was conducted to find out the prevalence of pre-existing uncorrected refractive error in presbyopes who attended the Eye O.P.D. in medical college of Bangalore (India). 100 presbyopes were selected according to inclusion criteria. Complete ophthalmic examination including visual acuity and objective & subjective refraction was performed. History of difficulty of vision was noted. Observations were tabulated and analyzed. 47 out of 100 presbyopes had pre-existing uncorrected refractive error. Most common complaint was difficulty of distance vision. 33 out of 47 had never used spectacles. Equal number of hyperopes and myopes were present. OBJECTIVE To find out the prevalence of uncorrected refractive errors in presbyopes attending Eye OPD in medical college in Bangalore INTRODUCTION Presbyopia is described as the condition wherein the eye exhibits a progressively diminished ability to focus on near objects with age. Thus there emerges the need of near vision corrective spectacles. The first symptoms present between the age of 40-50 years with difficulty in reading fine prints, in dim illumination, eyestrain after long reading hours and transient blur vision (1). 2 different definitions are cited in various studies. Functional presbyopia is defined as needing a significant optical correction added to the presenting distance refractive correction to achieve a near visual acuity criterion (more than or equal to 1 line of acuity improvement in one case, J1 print in another, and N8 print in the other) ( 2-4) . Objective presbyopia is defined as needing a significant optical correction (more than or equal to 1.00 D) added to the best distance optical correction to improve near vision to a near visual acuity criterion of N8 (5). The prevalence of presbyopia varies from region to region. In southern India, Nirmalan et al (5) found a prevalence of 55 per cent in people aged 30 years and older. Refractive errors affect a large proportion of the population worldwide, irrespective of age, sex and ethnicity. A significant number of these are never recognized and treated. These people in their presbyopic age present with uncorrected refractive errors. According to the Bulletin of the World Health Organization, in 2004, the number of people (above the age of 40 years) visually impaired from uncorrected refractive errors in India were almost 35 million (6). It was also shown that the coverage of refractive services in various regions of India ranges just between 40-55%. Uncorrected distance refractive error is the most common cause of vision impairment and the second most common cause of blindness in the world (6-9). This study is aims to find out the prevalence of pre-existing uncorrected refractive error in presbyopes attending Eye OPD in medical college in Bangalore.

Refractive error is a common and serious eye disorder that affects more than 153 million people globally. The aim of this study was to estimate the prevalence and pattern of refractive error among male primary school children in Jazan region, Saudi Arabia.A cross-sectional study was conducted among a randomly selected group of 395 students (aged 6-14 years) in Jazan region, Southwest Saudi Arabia. An optometrist and medical students assessed the refraction error using an autorefractor, a Snellen E chart and retinoscopy.The overall prevalence of uncorrected refractive error in either eye was, 22% higher among rural students. The most prevalent refractive error was hyperopia (32.2%) followed by myopic astigmatism (31%) then myopia (17.2%). Next were hyperopic astigmatism (16.1%) and mixed astigmatism (3.5%). The following variables were associated with a higher risk of refractive errors and myopia: living in rural areas, having parents with refractive errors, spending more time on electronic devices and shorter visual distances.Refractive error was highly prevalent among primary school children in Jazan, Saudi Arabia. The rural students were more affected by refractive errors, mainly hyperopia. The preschool vision test should be reconsidered, and a periodic vision examination should be applied to detect vision problems as early as possible.

Since last year (2015) MERCon publications are visible in the SCOPUS database/index. This is a significant achievement because SCOPUS is increasingly being used by many agencies to judge the research performance of both individuals and institutions. Both the THES (Times Higher Education Supplement) and QS (Quacquarelli Symonds) university ranking systems use SCOPUS. For this reason the University of Moratuwa is moving towards treating SCOPUS as a benchmark for quality publications. So MERCon's inclusion in SCOPUS is indeed a big step towards its international credibility; it will also probably attract progressively better quality papers in years to come, including overseas ones.

To assess the feasibility of providing a stock of ready made spectacles for correction of refractive error in the general population.Data were collected in the Visual Impairment Project, a population based survey of Victorian residents aged 40 years or older in randomly selected urban and rural sample areas. This included a refractive eye examination and the proportion of subjects with hypermetropia, emmetropia (defined as -1.0 to +1.0D spherical equivalent), and myopia documented in the 40-60 year age group.2595 (54.8%) participants were aged between 40 and 60 years. Those with a best corrected visual acuity of less than 6/12, astigmatism of more than 1.25D, and anisometropia of more than 0.5D were excluded. 516 participants had refractive error which was deemed suitable for correction by "off the shelf" spectacles. This represents 19.9% of all participants between 40 and 60 years of age. Provision of spectacles in 0.5D increments would provide suitable stock spectacles for 85.5% of a -3.0 to +3.0D range or 89.2% of a -3.50 to +3.50D range.Ready made "off the shelf" spectacles could significantly alleviate visual morbidity due to refractive error in up to 20% of an urban population in Australia. This approach may also be useful in developing countries with poor access to optometric services.

The Objective of the present research was to study the improvement of near vision with ready-made spectacles for presbyope in Chachoengsao province. Retrospective cross-sectional analytic study was conducted in 309 volunteers at Sanamchaiket district whose ages were 35 years and above. Visual acuity was measured in presbyopic patients, and then ready-made spectacles were given as a trial. Visual acuity of near distance was measured at the time before and after correction with ready-made spectacles. Aim was to achieve the visual acuity of 20/50 or better. The number of volunteers was 129. Out of these, 96.12 percent (124 of 129) achieved the aim of the visual acuity (124 of 129). In conclusion, ready-made spectacles were effective in correcting near vision for presbyope at any group of ages and both sexes in Chachoeungsao province. If the difference of refractive error between both eyes was greater than +1.25 Diopter ready-made spectacles were ineffective.

Abstract This study presents and explains the phenomenon of indexjacking , which involves the systematic infiltration of hijacked journals into international indexing databases, with Scopus being one of the most infiltrated among these databases. Through an analysis of known lists of hijacked journals, the study identified at least 67 hijacked journals that have penetrated Scopus since 2013. Of these, 33 journals indexed unauthorized content in Scopus and 23 compromised the homepage link in the journal's profile, while 11 did both. As of September 2023, 41 hijacked journals are still compromising the data of legitimate journals in Scopus. The presence of hijacked journals in Scopus is a challenge for scientific integrity due to the legitimization of unreliable papers that have not undergone peer review and compromises the quality of the Scopus database. The presence of hijacked journals in Scopus has far‐reaching effects. Papers published in these journals may be cited, and unauthorized content from these journals in Scopus is thus imported into other databases, including ORCID and the WHO COVID‐19 Research Database. This poses a particular challenge for research evaluation in those countries, where cloned versions of approved journals may be used to acquire publications and verifying their authenticity can be difficult.

Refractive errors is the eye’s inability to clearly focus light rays on the retinal plane. Certain refractive errors like myopia, hyperopia, presbyopia and astigmatism. Relief from refractive error associated with the use of prescribed spectacles and contact lenses.In 2006, 153 million people were living with uncorrected refractive error, as reported by the World Health Organization. The aim of this study was to create awareness on wearing spectacles among 18-25 years of individuals. This is a cross sectional survey based study and a set of questionnaires was prepared to analyze the knowledge and awareness of wearing spectacles among 18-25 years of individuals of south India and it was circulated. It has a sample size of 100 participants. Once the participants completed filling the survey, all the data were compiled for statistical analysis. It is evident from the study conducted that most of the people use spectacles to clear the refractive error and it is clear that most of them are aware about the consequences and treatment modalities of the refractive error and the use of spectacles. According to the above survey we conclude that the students are aware of wearing spectacles.

The Autorefractor 7 is a microcomputor assisted electro-mechanical optical system recently introduced to the professions for the subjective measurement of refractive error, phorias, and accommodative capacity. In this study of 450 eyes, 150 were wearing hard contact lenses, 150 wearing soft lenses, and 150 habitually wore a spectacle correction. Comparisons involved only the subjective refractive feature of the instrument and indicated no predictable difference in the three groups. Comparison of the Autorefractor 7 and clinical subjective refraction with the phoropter, however, showed that the instrument is reliable in the majority of cases but has a tendency to overcorrect myopia and astigmatism.
