The advent of assistive technology has brought considerable changes to the lives of older adults. From mobility aids to digital devices that help manage health, these advancements are making life more manageable for the elderly. However, questions often arise about the prolonged use of such technology. In particular, the impact of virtual assistive devices on the vision health of older adults is a subject of interest both for the scholars and the people who use them. Let’s delve into this topic, look at studies from renowned databases such as PubMed and CrossRef, and shed some light on this matter.
The Rising Use of Assistive Technology Among Older Adults
With aging comes an inevitable decline in various functionalities, prompting the need for assistance. Assistive devices have come to the aid of many older adults, offering increased independence, improving mobility, and enhancing overall quality of life. From walking aids to technologies that promote social connections, these devices have become an integral part of many seniors’ daily lives.

According to a study based on data from CrossRef and PubMed, the number of older adults using assistive technology has been on a steady rise. The study highlights that these adults are adopting technology at a rate faster than any other age group. This is primarily due to the increased demand for better health care and the desire to maintain independence and mobility, alongside the social benefits that technology offers.
Interestingly, virtual assistive devices are among the most commonly adopted technologies. These include gadgets like smartphones, tablets, personal computers, and smart home devices. They facilitate tasks such as communication, online shopping, health monitoring, and reminders for medication.

Impact of Assistive Devices on Vision Health
While assistive devices have revolutionized the lives of older adults, concerns have arisen over the impact of prolonged screen time on vision health. Consistent use of screens can lead to several eye-related issues such as dry eyes, blurry vision, difficulty focusing, and in severe cases, irreversible vision loss.
A study published on PubMed linked extended screen time with an increased risk of developing age-related macular degeneration (AMD), a leading cause of vision loss among older adults. The study further revealed that exposure to blue light emitted by screens might speed up the process of AMD.
Similarly, a Crossref-based study found that prolonged exposure to screens could lead to digital eye strain or computer vision syndrome. Symptoms include eye fatigue, dry eyes, red eyes, and blurry vision. These symptoms might not cause permanent damage, but they significantly affect the quality of life and daily productivity of older adults.
The Role of Assistive Devices in Managing Vision Health
While the potential risks are evident, it’s also crucial to highlight that assistive technology plays a significant role in managing and maintaining vision health. Many devices are designed to help older adults with low vision carry out their daily tasks more effectively. These include text-to-speech software, screen magnifiers, large-print keyboards, and audio books.
For instance, Google’s Lookout app uses AI to help visually impaired people by identifying objects and texts in their environment. Similarly, assistive devices like OrCam MyEye, a wearable device that fits onto glasses frames, can read text aloud from any surface, recognize faces, and identify products.
Maintaining good vision health is not solely dependent on limiting screen time. Regular eye check-ups, a balanced diet, adequate sleep, and eye exercises also play an essential role.
Recommendations for Prolonged Use of Assistive Devices
Even though assistive devices have potential risks, they’re indispensable in the life of an older adult. Therefore, it’s about finding a balance and using these technologies wisely. Guidelines for seniors who spend a significant amount of time on screens should be set in place.
Some of the recommendations include taking regular breaks from screen time, adjusting the screen brightness, increasing text size, and maintaining a reasonable distance between the eyes and the screen. The use of anti-glare screens and blue light blocking glasses may also help to reduce the strain on the eyes.
Additionally, seniors could be encouraged to utilize assistive technologies that do not involve screens. For example, voice-activated technologies like Google Home and Amazon Echo can provide assistance without the need to look at a screen.
The Future of Assistive Technology and Vision Health
The field of assistive technology is rapidly evolving, with newer, more user-friendly devices continually entering the market. These devices are expected to take into account the health implications of prolonged use, particularly concerning vision health.
In the future, we can anticipate more developments in assistive technology that cater to the specific needs of older adults. Innovations might include screenless devices, devices with eye-care settings, and even more advanced voice-activated assistants.
Furthermore, as we continue to understand the impact of assistive devices on vision health, there will be an increased emphasis on user education. Understanding the proper use of these devices can go a long way in preventing potential vision health issues.
Practical Measures to Minimize Vision Impacts
To safeguard the vision health of older adults using assistive technologies, practical measures can be taken. Prolonged screen time, a common concern among tech-savvy seniors, can contribute to vision loss. So, what are the steps that we can take to mitigate this risk?
First and foremost, the 20-20-20 rule is an effective practice to employ. This rule recommends that for every 20 minutes spent looking at a screen, one should take a 20-second break and look at something 20 feet away. This helps to relax the eye muscles and reduce digital eye strain.
Second, adjusting screen settings can also significantly reduce eye strain. This involves adjusting the screen brightness to match the light level in the environment, as well as increasing the text size for easier reading. Moreover, some devices come with an ‘eye-care’ mode that automatically adjusts the screen to a more eye-friendly setting.
To further protect eyes, the use of blue light blocking glasses can be beneficial. These glasses have specially crafted lenses that block or filter out the blue light given off from digital screens.
Lastly, regular eye check-ups are crucial for early detection of vision problems. Older adults, especially those using digital devices for extended periods, should have their eyes checked regularly by a professional. This allows for early detection and treatment of potential vision issues, thereby maintaining an optimal quality of life.
Conclusion: Balancing Benefits and Risks
Assistive technology has undoubtedly become an integral part of many older adults’ lives, providing them with a heightened sense of independence and improved quality of life. However, the potential health implications, specifically vision loss associated with prolonged screen use, cannot be overlooked.
While findings from PubMed and CrossRef studies illustrate the link between prolonged screen time and vision issues, Google Scholar and other databases also present a wealth of information on the ways to mitigate these risks.
Moreover, the rapid advancements in the field of assistive technology indicate a promising future. With a growing emphasis on user education and the development of more user-friendly, health-conscious devices, the potential risks can be minimized.
In conclusion, it is a balancing act between leveraging the benefits of assistive devices and managing their potential risks. With careful and educated use, older adults can enjoy the advantages of technology while preserving their vision health. As the area of gerontology continues to evolve, we remain hopeful for more innovative solutions that will enhance the quality of life for older people, without compromising their health.
