In a world increasingly reliant on digital technology, the health implications of prolonged screen exposure are coming to the fore. Electronic devices, while instrumental in various aspects of day-to-day life, can have significant consequences on our well-being, leading to conditions such as cybersickness and Vision-induced motion sickness (VIMS). These conditions, characterized by symptoms such as red eyes, nausea, and headaches, predominantly affect individuals who spend extended hours staring at screens.
The Silent Threat
Technology, an integral part of our lives, has subtly begun to interfere with our health and interpersonal relationships, a phenomenon now referred to as 'technoference.' Our eyes, in particular, are under constant strain due to the endless hours spent in front of screens. This strain may lead to eye abnormalities, including computer vision syndrome and macular degeneration, silent threats to eye health in the digital age.
Preserving Eye Health
To combat the adverse effects of screen time on eye health, the 20-20-20 rule is recommended. This rule emphasizes taking a 20-second break every 20 minutes to look at something 20 feet away, which has been found to result in less dryness and strain in the eyes. Other measures include maintaining a proper distance from the screen, avoiding high contrast with the surrounding room, and ensuring screens are kept clean.
Nutrition: An Unconventional Ally
The role of nutrition in mitigating the harmful effects of extended screen exposure is often overlooked. Consuming key nutrients can reduce the risk of macular degeneration. However, it's not just about physical health; screen time also has implications for mental well-being, sleep quality, and cognitive functions. It's particularly crucial for children to manage screen time effectively and for adults to set healthy examples.
Stepping Up Global Action
In the broader context, climate change poses a significant threat to eye health worldwide, especially in low and middle-income countries. The healthcare sector, a major contributor to the climate crisis, needs to undertake coordinated global action to achieve net-zero carbon healthcare and increase climate resilience. Sustainable practices in the healthcare sector can mitigate the effects of climate change on eye health.
As we navigate the digital era, it's paramount to address the potential harm to our health, particularly the brain. Both the negative and positive effects of excessive screen time and technology use, including technology addiction, social isolation, impaired brain development, and sleep disturbances, need to be carefully considered and managed.
