The digital age has brought with it a myriad of benefits, from instant communication to the ability to work from anywhere. However, it also carries a significant drawback: digital eye strain. With most young adults spending a vast majority of their time staring at screens, whether for work or leisure, eye health has become a growing concern. Optometrists are witnessing an increasing number of patients reporting symptoms associated with what is commonly referred to as computer vision syndrome or digital eye strain. This article aims to explore the challenge this presents to UK optometrists and the possible management strategies.
Recognising Digital Eye Strain
Before discussing management, we must first understand what we are dealing with – digital eye strain. It is a group of eye and vision-related problems resulting from prolonged computer, tablet, e-reader, and mobile phone use. As reported in several studies on PubMed and other medical literature databases, common symptoms include eye fatigue, dryness, burning, and blurred vision.

According to the American Optometric Association, digital eye strain/ computer vision syndrome is becoming more prevalent due to prolonged use of digital devices. This condition is not limited to adults. With the increasing age of digital device users, optometrists are also seeing these symptoms in children and teenagers.
When diagnosing digital eye strain, optometrists must consider several factors. The patient’s daily screen time plays a significant role, as well as their history of eye discomfort and visual fatigue. It’s also essential to consider the patient’s work environment, such as lighting and screen positioning.

The Role of Blue Light
A significant contributor to digital eye strain is the exposure to high-energy visible (HEV) light, also known as blue light. Digital screens, fluorescent and LED lighting, and even sunlight emit blue light. While it’s not inherently harmful, excessive exposure, especially from close proximity to screens, can lead to eye strain.
Research shows that blue light can cause digital eye strain by increasing the amount of focusing work our eyes have to do. It also decreases contrast, leading to digital eyestrain symptoms. Moreover, exposure to blue light during the evening can disrupt the circadian rhythm, leading to sleep problems. Optometrists need to educate patients about these risks and suggest strategies to reduce blue light exposure.
Management Strategies
Managing digital eye strain involves addressing both its causes and symptoms. On the preventative side, optometrists should advise patients to limit their screen time where possible. This could mean taking regular breaks during work or study using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.
Adjusting the workspace to be eye-friendly can also help. This includes proper screen positioning (the top should be level with the eyes or slightly below), adequate lighting, and using a matte screen filter to reduce glare. Optimizing screen settings, such as increasing text size and reducing brightness, can also be beneficial.
As for symptomatic relief, artificial tears can help with dry or irritated eyes. For those with significant symptoms, prescription glasses or contact lenses specifically designed for computer use might be an option.
The Importance of Regular Check-ups
Regular eye check-ups are vital for early detection and management of digital eye strain. Optometrists should advise patients, especially those in the high-risk group, to have regular eye examinations. These appointments provide an opportunity to assess the patient’s visual system, detect any problems, and advise on eye health and safety practices.
Ongoing Research and Innovations
The rise in digital eye strain incidence calls for continued research and innovation in the field of optometry. Several areas are worth exploring, such as the development of blue light filtering technology and the effectiveness of computer glasses. Optometrists should stay updated with the latest research findings and technology advances to provide their patients with the best care possible.
As we continue to embrace the digital age, it’s crucial to remember the impact on our eyes. Optometrists have a significant role to play in managing and mitigating the effects of digital eye strain. By recognizing the symptoms, understanding the causes, and implementing effective management strategies, we can ensure that our eyes remain healthy in the digital era.
Digital Eye Strain and Visual Health Education
To effectively manage digital eye strain, optometrists must also take on the role of educators. Their patients, especially young adults, may not fully comprehend the severity of their eye strain and the potential long-term consequences on their visual health. Optometrists need to educate patients about the causes and symptoms of digital eye strain, and also about strategies to prevent it.
These education efforts could be in the form of pamphlets, presentations, or one-on-one explanations during consultations. Optometrists might also consider partnering with schools and universities to reach a larger audience of young adults who are prone to digital eye strain due to their heavy screen time.
The education initiatives should also include information on the potential harm from blue light, the importance of taking digital breaks, and tips on setting up a visually healthy workspace. Optometrists can use credible sources like PubMed, Google Scholar, and Optom Vis Sci to provide scientifically-backed information.
Furthermore, optometrists can also use these platforms to educate about the symptoms of digital eye strain such as dry eye, eye fatigue, and blurred vision. By raising awareness, patients will be more inclined to seek help when these symptoms occur instead of dismissing them as routine fatigue.
The Use of Digital Devices and the Future of Eye Health
As we continue to immerify ourselves in the digital era, the use of digital devices will only increase. This inevitable rise will likely cause an increase in digital eye strain cases, posing a significant public health challenge for UK optometrists. Therefore, it is crucial for the optometry field to proactively address this issue by providing practical management strategies and preventative education.
Regular eye check-ups should be promoted as a necessary routine, not only for correcting vision but also for maintaining overall eye health. The development of spectacles and contact lenses with built-in blue light filters shows promise and should be considered as a preventive measure for regular digital device users.
Advancements in technology should be leveraged to improve eye health. For instance, software that reminds users to take regular breaks and adjust their screen settings can be beneficial. Additionally, as noted in some articles on PubMed, blink rate significantly decreases during digital device use, which contributes to dry eye symptoms. Therefore, future innovations could focus on addressing this issue.
Research focusing on digital eye strain should be encouraged. The results from these studies can provide a deeper understanding of this modern age vision syndrome, allow for the development of more effective management strategies, and form the basis for visual health policies.
In conclusion, managing the increasing incidence of digital eye strain in young adults requires a holistic approach that combines effective management strategies, preventive measures, patient education, and continuous research. Optometrists play a crucial role in this endeavour and must remain updated with the latest developments in the field to provide the best care for their patients. The digital era should be seen not only as a challenge but also as an opportunity to advance optometry and promote better eye health.
