Dry eye disease is a common condition affecting one-third of the adult population and one-in-five children

Professor James Wolffsohn researched the most effective blinking exercises to reduce discomfort, involving a close-squeeze-blink cycle

He developed the MyDryEye app in collaboration with Alec Kingsnorth and Mark Nattriss to help sufferers


An Aston University optometrist, Professor James Wolffsohn, has determined an optimum blinking exercise routine for people suffering with dry eye disease, and has developed a new app, MyDryEye, to help them complete the routine to ease their symptoms.


Dry eye disease is a common condition which affects one-third of the adult population and one-in-five children, in which the eyes either do not make enough tears, or produce only poor-quality tears. It causes the eyes to become uncomfortable, with gritty- or itchy-feeling eyes, watery eyes and short-term blurred vision. It is more common in older adults and can be exacerbated by factors including dry air caused by air conditioning, dust, windy conditions, screen use and incomplete blinks, where the eye does not fully close.


Professor Wolffsohn is head of Aston University’s School of Optometry and a specialist in dry eye disease. While it has long been known that blinking exercises can ease the symptoms of dry eye disease, the optimum technique, number of repetitions and necessary repeats per day are unclear. Professor Wolffsohn set out to determine the best exercises.


His team found that the best technique for a dry eye blinking exercise is a close-squeeze-blink cycle, repeated 15 times, three times per day. Participants found that while they were doing their exercises symptom severity and frequency decreased, and the number of incomplete blinks decreased. Within two weeks of stopping the exercises, their symptoms returned to normal levels, showing the efficacy of the exercises.


To carry out the work, Professor Wolffsohn’s team ran two studies. For the first, they recruited 98 participants, who were assessed for dry eye symptoms before and after the two weeks of blinking exercises. Participants were randomly allocated different blinking exercises to determine the most effective. A second study with 28 people measured the efficacy of the blinking exercise.


Once the optimum blinking routine had been developed, Professor Wolffsohn worked withAlec Kingsnorth, an engineer and former Aston undergraduate and PhD student, and Mark Nattriss, business manager of his spin-out company, Wolffsohn Research Ltd, to develop the app, MyDryEye, which is freely available on Android and iOS operating systems. The app allows users to monitor their dry eye symptoms, assess their risk factors, add treatment reminders and monitor their compliance, complete the science-based blink exercises and find a specialist near them.


Professor Wolffsohn says that the blinking exercises should be carried out as part of a treatment programme which could also include the use of lipid-based artificial tears, omega-3 supplements and warm compresses.


Professor Wolffsohn said:


“This research confirmed that blink exercises can be a way of overcoming the bad habit of only partially closing our eyes during a blink, that we develop when using digital devices. The research demonstrated that the most effective way to do the exercises is three times a day, 15 repeats of close, squeeze shut and reopen – just three minutes in total out of your busy lifestyle. To make it easier, we have made our MyDryEye app freely available on iOS and Android so you can choose when you want to be reminded to do the exercises and for this to map your progress and how it affects your symptoms.”

Aston University’s Ian Maidment helps develop training for pharmacy staff supporting those with long COVID

The e-learning resource, Supporting people living with long COVID, was developed by the Centre for Pharmacy Postgraduate Education (CPPE) It is designed to help community pharmacy teams build their skills, knowledge and confidence The programme offers video and audio resources, practical consultation examples and strategies for supporting individuals. Professor Ian Maidment at Aston Pharmacy School has been involved in a project with the Centre for Pharmacy Postgraduate Education (CPPE) to develop a new e-learning programme for community pharmacists, called Supporting people living with long COVID. The programme is designed to help community pharmacy teams build their skills, knowledge and confidence to support people managing the long-term effects of COVID-19. It was developed with researchers undertaking the National Institute for Health and Care Research (NIHR)-funded PHARM-LC research study: What role can community PHARMacy play in the support of people with long COVID? During the development of the e-learning resource, as well as with Professor Maidment, CPPE worked in collaboration with researchers from Keele University, the University of Kent, Midlands Partnership University NHS Foundation Trust and lechyd Cyhoeddus Cymru (Public Health Wales). The research draws on lived experience of long COVID, as well as the views of community pharmacy teams on what learning they need to better support people living with the condition. This new programme offers video and audio resources, practical consultation examples and strategies for supporting individuals through lifestyle advice, person-centred care and access to wider services. Professor Maidment said: “As an ex-community pharmacist, community pharmacy can have a key role in helping people living with long COVID. The approach is in line with the NHS 10 Year Health Plan, which aims to develop the role of community pharmacy in supporting people with long-term conditions.” Professor Carolyn Chew-Graham, professor of general practice research at Keele University, said: “Two million people in the UK are living with long COVID, a condition people are still developing, which may not be readily recognised, because routine testing for acute infection has largely stopped. For many, the pharmacy is the first place they seek advice about persisting symptoms following viral infection. The pharmacy team, therefore, has the potential to play a really important role in supporting people with long COVID. This learning programme provides evidence-based information to develop the confidence of pharmacy staff in talking to people with long COVID. Developed with people living with long COVID, the programme’s key message is to believe and empathise with people about their symptoms.” Visit www.cppe.ac.uk/programmes/l/covid-e-01 to access the e-learning programme. This project is funded by the National Institute for Health Research (NIHR) under its Research for Patient Benefit (RfPB) Programme (Grant Reference Number NIHR205384).

Deaf children share insights on what researchers should study next in Aston University co-led project

Aston University’s Dr Amanda Hall co-led the study with Dr Anisa Visram from the University of Manchester Deaf children and those with experience of childhood deafness have identified their top 10 research priorities including education and family relationships The project was funded by the National Deaf Children’s Society Deaf children and people with experience of childhood deafness from across the UK have come together to highlight what matters most to children affected by deafness and hearing loss, as part of a project funded by the National Deaf Children’s Society (NDCS). From 2023 to 2025, a team of parents, young people and health and education professionals set out to compile a list of the ‘Top 10’ most important questions that researchers should be trying to answer about childhood deafness and hearing loss. The project was co-led by Dr Amanda Hall, a senior lecturer in audiology at Aston University, and Dr Anisa Visram from the University of Manchester in conjunction with researchers at Lancaster University. The hope is that it will ultimately lead to more research into childhood deafness, in the specific areas it’s needed most. Children highlighted the potential impact of them missing out on things happening around them when interacting with their peers as their top priority, demonstrating the importance of social development for deaf children. Family relationships and educational needs ranked as high priorities for both adults and children, coming in the top 3 for both groups. Adults ranked educational needs as number 1, highlighting the importance of supporting deaf children in schools, particularly those with additional needs. Other important areas for research included understanding what support is needed for children with mild and unilateral (on one side) deafness, the impact of language deprivation on deaf children and how deaf children can be supported to understand their deafness and become empowered to advocate for themselves as they grow up into deaf adults. Several hundred respondents contributed to the project through a series of online surveys. Children were involved through activity-based focus groups. Respondents submitted over 1,200 ideas for research questions in the initial surveys. These were summarised into a list of 59 unique questions, and a second survey was used to prioritise the questions. The top 21 questions were then taken to two final full-day workshop where participants collaborated to choose their top 10 priorities. The research team used what’s known as a James Lind Alliance (JLA) priority-setting process to ensure the robustness of the project. Participants reported feeling valued as part of the project and satisfied that their feedback is reflected in the final lists. One of the children who took part in the workshop said: “I learnt that my voice matters and I can make a difference for me and other deaf children.” Dr Hall said: “It has been a real privilege to be part of this JLA partnership, working alongside deaf young people, families of deaf children and professionals to identify our two sets of top 10 research questions. We hope this is just the beginning of more research that reflects what matters most to deaf children, their families and professionals, and of more opportunities to work together.” Dr Visram said: “This has been an incredible project to work on with an amazing, committed, and diverse stakeholder group feeding into the process at all stages. We have formed important collaborations with deaf young people, parents of deaf children, and a whole range of professionals working with deaf children. The group plan to keep working together to promote the Top 10 lists and help develop research projects to start to answer these important questions.” Juliet Viney is a parent to a deaf child and has supported the project as a parent partner. She said: “It has been an absolute privilege working as a parent partner developing our Top 10 most important research questions for childhood deafness. This project has brought together and empowered deaf children and young people, parents and professionals from across the UK; using their valuable lived experiences to provide them with a strong voice to guide researchers towards addressing what is most needed to improve deaf children's educational, health, social and emotional outcomes. I am excited to see which questions will be pursued in further research and the positive impacts these will have on the lives of deaf children!” Dr Sian Lickess, Research and Analysis Lead at the National Deaf Children’s Society, said: “We are proud to have supported this important partnership, which has brought together the voices of deaf children, their families and professionals to shape future research priorities. The resulting Top 10 lists represent an important step toward ensuring research is aligned with real-world needs and is meaningful to those most affected. We look forward to the impact this work will have on improving outcomes for deaf children.” The full list of priorities identified can be found at: www.childdeafnessresearch.co.uk. As well as the National Deaf Children’s Society, several other partners have also contributed to the project. These include the Professor Kevin Munro’s National Institute for Health and Care Research (NIHR) Senior Investigator award, NIHR Manchester Biomedical Research Centre, PF Charitable Trust, Research England’s QR Participatory Research Fund to Lancaster University, and UKRI Future Leaders Fellowship MR/X035999/1.

Professor Roslyn Bill selected for the inaugural cohort of the Big if True Science accelerator

Professor Roslyn Bill is the director of Aston Institute for Membrane Excellence (AIME) The Big if True Science (BiTS) accelerator aims to bridge the gap between cutting-edge lab science and multi-million-dollar collaborative projects Professor Bill’s research is focused on the brain’s plumbing system and developing drugs against traumatic brain injury and cognitive decline. Professor Roslyn Bill, director of Aston Institute for Membrane Excellence (AIME), has been selected as an inaugural fellow of the new Big if True Science (BiTS) accelerator. BiTS was set up by a non-profit organisation, Renaissance Philanthropy, to support its scientist and innovator fellows in developing groundbreaking research initiatives and equip them with the tools, skills, and networks needed to design high-impact, collaborative research programmes and technical projects with multi-million-dollar budgets beyond their own laboratories. The first cohort of 12 fellows was selected after a highly competitive process. The cohort represents diverse fields including neuroscience, environmental engineering, biomedical research, and materials science. Over a 15-week period, they will transform their breakthrough concepts into fundable eight-figure R&D programmes, before pitching their ideas to funders on 10 December 2025. Professor Bill’s research focuses on the glymphatic system, the brain’s ‘plumbing’ system, which facilitates the movement of fluid and clears waste products. Water moves in and out of brain cells through tiny protein channels in the cell membrane called aquaporins. Uncontrolled water entry, for example, after a head injury, can cause catastrophic swelling and severe brain injuries of the type suffered by racing driver Michael Schumacher after a skiing accident. When the flow is impeded, for example, as we age, waste products can build up, leading to diseases like Alzheimer’s. In 2020, Professor Bill was lead author on a paper published in the prestigious journal Cell on how the flow of water through aquaporin-4 is controlled. She is now researching drugs to affect this process, which could have a huge impact on the treatment of traumatic brain injury and cognitive decline. Professor Bill said: “Every year, tens of millions of people are affected by injuries to their brains. Every three seconds, someone in the world develops dementia. There are no medicines that can fix these terrible conditions. Being an inaugural member of BiTS is a great honour, and I am delighted to be in the company of truly inspiring people. This exciting programme offers hope to patients for whom no medicines are available!”
