Screen Time: Excessive use of digital devices such as smartphones, tablets, and computers can strain our eyes. Staring at screens for extended periods can lead to digital eye strain, characterized by symptoms like dryness, blurred vision, headaches, and eye fatigue.
Blue Light: Digital screens emit blue light, which has shorter wavelengths and higher energy compared to other colors. Prolonged exposure to blue light can disrupt our sleep patterns, cause eye strain, and potentially contribute to long-term vision problems.
Reduced Blinking: When using technology, we tend to blink less frequently, which can result in dry eyes. Blinking helps distribute tears that keep the eyes lubricated and moist. Insufficient blinking can lead to discomfort, irritation, and dryness.
Poor Ergonomics: Incorrect posture and poor ergonomics while using technology can strain our eyes. For example, sitting too close to a screen or positioning it at an inappropriate height can put extra stress on our eyes and contribute to discomfort.
Near-Work Activities: Technology often involves near-work activities, such as reading small text on screens or focusing on nearby objects for prolonged periods. Such activities can lead to eye fatigue and strain the muscles responsible for focusing, leading to conditions like eye strain or even myopia progression.
Lack of Outdoor Time: Excessive use of technology can lead to a sedentary lifestyle, reducing the time spent outdoors. Outdoor activities and exposure to natural light are important for eye health, as they help regulate eye growth and reduce the risk of developing myopia. To mitigate the potential negative effects of technology on eyesight, it’s advisable to take regular breaks, follow the 20-20-20 rule (look at something 20 feet away for 20 seconds every 20 minutes), adjust screen brightness and blue light filters, maintain good posture, ensure proper lighting conditions, and practice overall eye hygiene. Regular eye exams are also important to monitor and address any vision changes or concerns.
