Improving and re-developing the Clerical Resolution Online Widget (CROW): open-source software for clerical review

ObjectivesClerical review is an integral part of linkage and is fundamental to quality assurance. CROW is a low dependency, adaptable, clerical matching tool that has been deployed across 40 linkage projects. Due to limitations of the interface, with the initial version (including the limited ability to view large clusters); this project sought to re-develop the tool as a flask application. ApproachOur approach was to transform the existing CROW desktop application into a Flask (web based) application. Flask was chosen because it is a flexible web framework that enabled the development of a more dynamic interface, as well as better integration with the infrastructure of secure environments. We also engaged with accessibility experts to ensure the inclusivity of our product. Once the development was completed, testing was carried out by a range of users and stakeholders, to identify further issues and bugs for resolution. ResultsThe successful redevelopment of CROW into a Flask application improved functionality, usability, parametrisation, and accessibility of the tool. Feedback from users indicates that because of using CROW, the clerical matching experience has improved vastly. Users reported that CROW increased accessibility, reducing eye strain and fatigue. CROW also increases efficiency and leads to better decision making. ConclusionThe successful redevelopment of CROW is a significant improvement to the clerical review process for data linkage projects. ImplicationsCROW is open-source and low dependency so could be adapted to work in most environments. Therefore, it could be adapted and used by the wider data linkage community.

Blue-Violet Light-Blocking Eye Protectors in Dental Practice: A Preliminary Study

Healthcare professionals are exposed to various intense light sources during dental practice. Of particular concern is blueviolet light (wavelength 380-500 nm), which can impact retinal health, necessitating effective mitigation strategies. In this study, we assessed the practical utility of lenses designed to reduce blue-violet light to wavelengths of approximately 420 nm or shorter within the dental practice setting. Two dentists and four dental hygienists participated in the study. The participants wore either blue-light-reducing lenses or lenses with no effect for one month. The degree of eye strain was evaluated using flicker values. The results revealed that four of the six participants experienced reduced eye strain while wearing blue-violet light-reducing lenses. In conclusion, this study addresses the acknowledged impact of blue-violet light on retinal health. However, the long-term prognosis remains uncertain. Therefore, considering the potential unknown effects, it is necessary to discuss the use of blue-violet light-cut lenses in everyday practice as a risk-management strategy.

Different from previous studies, this research, in addition to finding problems, also offers useful solutions for online reading learning.

YOGA eye exercises and Refractive Errors

The article delves into the prevalent issue of refractive errors, a common visual problem affecting a substantial portion of the global population, and particularly emphasizes its growing occurrence among school-going children. The surge in digital device usage due to the COVID-19 pandemic has amplified concerns, as extended screen time contributes in worsening the existing problem of poor vision. The article underscores the multifaceted impact of unaddressed refractive errors on children, including hindered academic performance, impaired social interactions, and a sedentary lifestyle. Socioeconomic and demographic factors play a role in the prevalence of refractive errors, with limited access to eye care services disproportionately affecting lower-income families. The importance of early diagnosis and intervention is highlighted to prevent unwanted consequences. A significant portion of the article explores the potential role of yoga in mitigating refractive errors. Yoga's holistic approach, incorporating eye exercises, mindfulness, stress reduction, and outdoor practice, offers promise in promoting eye health. While acknowledging that yoga may not correct refractive errors, the article emphasizes its potential to reduce eye strain caused by screen time and near-work activities, ultimately fostering healthier habits and overall well-being in children. The article concludes by emphasizing the need for complementary practices alongside standard eye care to ensure children's visual health and academic success while suggesting that embracing yoga could be a step toward safeguarding children's eye health and quality of life.

REMINDEE - A Break Time Reminder Application

The usage of mobile devices has been steadily increasing, with the average time spent on mobile devices exceeding 4.5 hours per day in 2022, leading to negative impacts on users' health. In response to this issue, the REMINDEE project was developed to create a mobile app using Flutter that promotes regular breaks from screen time. The app encourages users to take short breaks, following the 20-20-20 rule, which involves looking away from the screen every 20 minutes, for 20 seconds, at an object that is 20 feet away. During break time, the app blocks all actions on the device, ensuring that the user cannot continue using the device. The project aims to reduce screen time and encourage users to take regular breaks, which can help reduce eye strain, prevent headaches, and improve overall health. The app also allows users to customize their break time, set reminders, and view their usage statistics to help monitor their progress. Ultimately, the REMINDEE project aims to promote healthy screen time habits, allowing users to maintain their health and well-being while still staying connected to their devices.

The Clerical Resolution Online Widget (CROW): creating open-source software to make clerical review easier.

ObjectivesQuality assessment is an integral part of linkage, often involving clerical (manual) review of records. Excel spreadsheets are commonly used to review record pairs, which can be difficult to read across the screen. We decided to create an adaptable piece of software that improved the user experience. ApproachOur approach was to utilise tkinter, a pythonic graphical user interface (GUI) package. Tkinter is easy to use and has simple syntax, making it a good choice for open-source code. The software takes in wide format datafiles and displays record pairs one at a time in an easy-to-compare format, allowing a user to select whether the items are a ‘match’ or a ‘non-match’. By adapting parameters in a configuration file, a user can very easily adapt the CROW to the variables available in each dataset. We have also developed capability for highlighting differences between record pairs. ResultsFeedback from users indicates that as a result of using CROW, the clerical matching experience has improved vastly. Users reported that CROW increased accessibility, reducing eye strain and fatigue. CROW also increases efficiency, allowing projects to complete earlier than planned. On one key Labour Market Survey based linkage, the CROW led to an estimated 25% time saving. The ability to highlight the differences in records increases the accuracy and efficiency of decision making. We were successful in building adaptable software, that can be transferred to different datasets. It has been used in a wide range of projects across the ONS including key Covid-19 and Census 2021 linkage projects. The open-sourced nature of this software means it is freely available for use. ConclusionIn conclusion, CROW is an open-sourced piece of software for clerical review that is easy to use and adapt; it makes the experience of clerical review more pleasant as well as saving resources. It is a useful tool that enables quality assurance to be broadly implemented across the linkage domain.

Digital Eye Strain- A Comprehensive Review.

Digital eye strain (DES) is an entity encompassing visual and ocular symptoms arising due to the prolonged use of digital electronic devices. It is characterized by dry eyes, itching, foreign body sensation, watering, blurring of vision, and headache. Non-ocular symptoms associated with eye strain include stiff neck, general fatigue, headache, and backache. A variable prevalence ranging from 5 to 65% has been reported in the pre-COVID-19 era. With lockdown restrictions during the pandemic, outdoor activities were restricted for all age groups, and digital learning became the norm for almost 2 years. While the DES prevalence amongst children alone rose to 50–60%, the symptoms expanded to include recent onset esotropia and vergence abnormalities as part of the DES spectrum. New-onset myopia and increased progression of existing myopia became one of the most significant ocular health complications. Management options for DES include following correct ergonomics like reducing average daily screen time, frequent blinking, improving lighting, minimizing glare, taking regular breaks from the screen, changing focus to distance object intermittently, and following the 20-20-20 rule to reduce eye strain. Innovations in this field include high-resolution screens, inbuilt antireflective coating, matte-finished glass, edge-to-edge displays, and image smoothening graphic effects. Further explorations should focus on recommendations for digital screen optimization, novel spectacle lens technologies, and inbuilt filters to optimize visual comfort. A paradigm shift is required in our understanding of looking at DES from an etiological perspective, so that customized solutions can be explored accordingly. The aim of this review article is to understand the pathophysiology of varied manifestations, predisposing risk factors, varied management options, along with changing patterns of DES prevalence post COVID-19.

Characteristics and attitudes of general and pediatric dentists who use loupes.

Dental loupes are used by dental professionals to improve visual performance, reduce eye strain and prevent musculoskeletal disorders. Data on their usage in pediatric dentistry are scarce. We performed a cross-sectional survey to evaluate the approach, knowledge, and frequency of using loupes among 100 general and pediatric dentists. showed that the use of loupes is significantly more prevalent among general dentists (64.3%) compared to pediatric specialists and residents (35.7%). Among dentists who reported that they do not use loupes, 63.6% were pediatric dentists and residents, and 82.5% were dentists working with children. A significantly higher percentage of dentists who self-reported as loupes users perceived that the loupes afford comfortable and stable posture, confidence while working, and contribute to the detection of tooth decay. A significantly higher percentage of dentists who self-reported as non-users of loupes (compared to loupes users), claimed that they weaken the eyes, require long adjustment, and cause discomfort. Although the use of loupes in general dentistry is becoming more prevalent, there is still a need to raise awareness for this vision aid among pediatric dentists while promoting its advantages, to reap benefits associated with their usage.

291 A Pilot Study of Light Management in the US Navy

Abstract Introduction Exposure to light at appropriate times can improve alertness and mood; however, light can also interfere with sleep if exposure occurs before bedtime. Therefore, light management is important for sailor well-being and operational performance. One approach to administer light in field settings is to use personal wearable devices. This pilot study assessed the challenges in using the blue-light blocking goggles (BLBG) and light emitting goggles (LEG) for crewmembers of a US Navy ship while underway. Methods Longitudinal (~2 weeks) assessment of sailors (N=18) during deployment. Sailors completed a questionnaire asking whether they used the devices, reasons (if any) they may have had for not using the devices, what they liked/did not like about the devices, and whether wearing the devices made a difference in terms of fatigue, alertness, ability to fall asleep, and reported sleep quality. Results Sailors reported that the LEGs seemed to increase alertness (n=8) and helped wake up faster (n=5), but the devices were bulky/heavy (n=9), too bright (n=4), and made it difficult to see in dim light (n=2). The reported reasons for not using the devices include: the devices were heavy/uncomfortable (n=5), they caused eye strain (n=4), and the LEGs interfered with sailor ability to see while on watch (n=3). Also, wearing the LEGs made sailors feel less tired (71%) and more alert (59%). Sailors reported that the BLBGs kept them drowsy before bed (n=3) and reduced eye strain (n=5). Sailors complained, however, that BLBGs were bulky/inconvenient (n=3). When not wearing the BLBGs, it was because the devices were easy to forget (n=2), sailors had to work after their shift (n=2), and other reasons (n=3). Wearing the BLBGs during watch made falling asleep easier (47%) and improved sleep quality (47%). Conclusion This study provided valuable insight regarding the use of personal wearable light management devices in field settings. Even though not conclusive, our results are promising. We will continue assessing the utility of such devices with a goal of improving sailor well-being and operational performance.

Do Blue-blocking Lenses Reduce Eye Strain From Extended Screen Time? A Double-Masked Randomized Controlled Trial

To investigate if blue-blocking lenses are effective in reducing the ocular signs and symptoms of eye strain associated with computer use. Double-masked, randomized controlled trial. A total of 120 symptomatic computer users were randomly assigned (1:1) into a "positive" or "negative" advocacy arm (ie, a clinician either advocating or not advocating for the intervention via a prerecorded video). Participants were further sub-randomized (1:1) to receive either clear (placebo) or blue-blocking spectacles. All participants were led to believe they had received an active intervention. Participants performed a 2-hour computer task while wearing their assigned spectacle intervention. The prespecified primary outcome measures were the mean change (post- minus pre-computer task) in eye strain symptom score and critical flicker-fusion frequency (CFF, an objective measure of eye strain). The study also investigated whether clinician advocacy of the intervention (in a positive or negative light) modulated clinical outcomes. All participants completed the study. In the primary analysis, for CFF, no significant effect was found for advocacy type (positive or negative, p=.164) and spectacle intervention type (blue-blocking or clear lens, p=.304). Likewise, for eye strain symptom score, no differences were found for advocacy (p=.410) or spectacle lens types (p=.394). No adverse events were documented. Blue-blocking lenses did not alter signs or symptoms of eye strain with computer use relative to standard clear lenses. Clinician advocacy type had no bearing on clinical outcomes.

Desktop-LED lighting for Eye Muscle Movement by Adjusting the Light Illuminance and Color Temperature

In this paper, we propose the design and implementation of a desktop LED stand and smart app that automatically adjusts color temperature and illuminance for optimal brightness and eye health by improving the structural problem of the LED stand. It is a tabletop LED stand that supports optimal brightness through color temperature control and heat transfer through infrared LED to relieve eye strain through blood circulation and muscle movement. The LED stand works with the smartphone to automatically adjust the optimal brightness and color temperature for the user's environment. In addition, the brightness of the infrared LED is adjusted to a living frequency of 4Hz to relax the eye muscles and reduce eye strain. This study implemented an effective measured data-based system of previous studies through the color temperature and illumination of LED lighting, and near-infrared rays, and presented meaningful results by conducting an experiment to prove the effect through subjects.

Why doesn’t everyone love reading e-books?

Why do many students still prefer paper books to e-books? This article summarizes a number of problems with e-books mentioned in different studies by students of higher education, but it also discusses some of the unexploited possibilities with e-books. Problems that students experience with e-books include eye strain, distractions, a lack of overview, inadequate navigation features and insufficient annotation and highlighting functionality. They also find it unnecessarily complicated to download DRM-protected e-books. Some of these problems can be solved by using a more suitable device. For example, a mobile device that can be held in a book-like position reduces eye strain, while a device with a bigger screen provides a better overview of the text. Other problems can be avoided by choosing a more usable reading application. Unfortunately, that is not always possible, since DRM protection entails a restriction of what devices and applications you can choose. Until there is a solution to these problems, I think libraries will need to purchase both print and electronic books, and should always opt for the DRM-free alternative. We should also offer students training on how to find, download and read e-books as well as how to use different devices.

Effectiveness of a participatory eye care program in reducing eye strain among staff computer users in Thailand.

BackgroundThe increased usage of computers results in a variety of health problems, particularly eye strain, which is the most common workplace complaint today.ObjectivesThis study aimed to evaluate the effectiveness of a participatory eye care (PEC) program by comparing eye care knowledge, attitude, and practice (KAP), as well as eye strain symptoms in staff computer users at Sukhothai Thammathirat Open University, Thailand.MethodsA participatory approach was held by organizing a meeting of 26 stakeholders to get opinions for developing the PEC program. The developed PEC program consisted of 3-hour training course on eye strain, rest breaks for 30 seconds every 30 minutes of computer use, and 15-minute rest break (in the morning and the afternoon) with integrated eye–neck exercises. Then, a quasi-experiment was conducted to evaluate the effectiveness of the PEC program. A total of 35 staff computer users enrolled in each of intervention and control groups for 8 weeks. Chi-square test and repeated measures analysis of variance were used for comparison of eye strain symptoms and the KAP scores.ResultsThe intervention was associated with reduction in percentage of eye strain. Significant differences were found between the intervention and the control groups at follow-up 1 (χ2=18.529, p-value <0.001) and follow-up 2 (χ2=18.651, p-value <0.001). The PEC program likely increased the beneficial effect on KAP scores between the groups and between times (p<0.05).ConclusionThe findings currently provide evidence to support a practical program developed through a participatory approach, which both researchers and computer users could apply to reduce eye strain.

Short-Wavelength Light-Blocking Eyeglasses Attenuate Symptoms of Eye Fatigue

The purpose of this study was to determine whether subjects who wear short wavelength-blocking eyeglasses during computer tasks exhibit less visual fatigue and report fewer symptoms of visual discomfort than subjects wearing eyeglasses with clear lenses. A total of 36 healthy subjects (20 male; 16 female) was randomized to wearing no-block, low-blocking, or high-blocking eyeglasses while performing a 2-hour computer task. A masked grader measured critical flicker fusion frequency (CFF) as a metric of eye fatigue and evaluated symptoms of eye strain with a 15-item questionnaire before and after computer use. We found that the change in CFF after the computer task was significantly more positive (i.e., less eye fatigue) in the high-block versus the no-block (P = 0.027) and low-block (P = 0.008) groups. Moreover, random assignment to the high-block group but not to the low-block group predicted a more positive change in CFF (i.e., less eye fatigue) following the computer task (adjusted β = 2.310; P = 0.002). Additionally, subjects wearing high-blocking eyeglasses reported significantly less feeling pain around/inside the eye (P = 0.0063), less feeling that the eyes were heavy (P = 0.0189), and less feeling that the eyes were itchy (P = 0.0043) following the computer task, when compared to subjects not wearing high-blocking lenses. Our results support the hypothesis that short-wavelength light-blocking eyeglasses may reduce eye strain associated with computer use based on a physiologic correlate of eye fatigue and on subjects' reporting of symptoms typically associated with eye strain.

A CLINICAL STUDY OF THE EFFECT OF TILA TAILA PADABHYANGA ON EYE STRAIN

Due to changed life style we are giving more strain to our eyes. For serving this , Ayurveda emphasized on Padabhyanga. The Acharyas have told that Padabhyanga he lps to improve our vision. In further context they have mentioned a link between Pada and Netra as two poles of our body. This study had tried to explore the ro le of Padabhyanga in Dincharya and the effect of Tila T aila Padabhyanga in Eye Strain. A total o f 60 diagnosed patients of eye strain were registered and randomly divide d into two groups. In Group A, daily Tila Taila Padabhyanga and 500 mg Yashtimadhu choorna capsule with lukewarm water at night was given while in Group B only 500 mg Yashtimadhu choo rna capsule with lukewarm water a t night was given for 60 days. Assessment of efficacy in symptoms weakness and heaviness of eyes was don e at 15 days interval. t test and χ 2 test were applied. Results showed that i n Group A 70% showed improvement in w eakne ss while in Group B 33.33% improved. Improvement in heaviness was observed in 33.33% Group A while 23.33% Group B patients. There was highly significant (p ˂ 0.01 unpaired t test, p ˂ 0.001 χ 2 test ) improvement in weakness of eyes in Group A but there was no significant difference between two therapies (p ˂ 0.2 unpaired t test, p ≥ 0.5 χ 2 test ) in heaviness of eyes. Thus r egular practicing Tila Taila Padabhyanga is very beneficial for reducing Eye Strain. The Nityabhyasa of Padabhyanga may prevent its sympt oms.

We fabricated prototypes of a 434‐ppi 5.9‐in reflective liquid crystal display for use as an e‐book reader. With high‐level optical characteristics with a reflectance of 25.1% and an NTSC ratio of 37%, we achieved eye‐friendly reflective LCD.

Color Me Noisy: Example‐based Rendering of Hand‐colored Animations with Temporal Noise Control

AbstractWe present an example‐based approach to rendering hand‐colored animations which delivers visual richness comparable to real artwork while enabling control over the amount of perceived temporal noise. This is important both for artistic purposes and viewing comfort, but is tedious or even intractable to achieve manually. We analyse typical features of real hand‐colored animations and propose an algorithm that tries to mimic them using only static examples of drawing media. We apply the algorithm to various animations using different drawing media and compare the quality of synthetic results with real artwork. To verify our method perceptually, we conducted experiments confirming that our method delivers distinguishable noise levels and reduces eye strain. Finally, we demonstrate the capabilities of our method to mask imperfections such as shower‐door artifacts.

P‐135: Reflective LCD without Flicker for Reduced Eye Strain

AbstractWe fabricated a 6.05‐inch reflective liquid crystal display (LCD) using a CAAC‐OS for a driving transistor. We achieved low frequency driving at 1/60 fps or lower and flicker reduction. With our LCD, eye strain can be reduced more than with an electrophoretic display.
