Myopia is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. It can be caused by the eyeball being too long, relative to the focusing power of the cornea and lens of the eye. This causes light rays to focus on a point in front of the retina, rather than directly on its surface. If you've been diagnosed with myopia, or if you often experience blurry vision, headaches, eyestrain, or squinting, your digital lifestyle might be a contributing factor.
When you stare at a screen for prolonged periods, your eyes are constantly focused on a fixed, close point. This continuous close work can strain your eyes and may lead to myopia over time. This is because your eyes are not meant to be fixated on a single close point for extended periods. They are designed to shift focus from near to far objects frequently.
Furthermore, the blue light emitted by digital screens can also contribute to eye strain and discomfort. Although the link between blue light and myopia is not as direct, prolonged exposure to high-energy visible (HEV) blue light can potentially damage the light-sensitive cells in your retina, leading to conditions like macular degeneration.
Reducing the impact of screen time on myopia is not about eliminating digital devices from your life. Instead, it's about adopting healthier habits around their usage. One such strategy is to take frequent breaks: every 20 minutes, take a 20-second break and look at something 20 feet away. This simple habit can relieve the strain on your eyes and reduce the risk of myopia.
Another strategy is to adjust the brightness and contrast of your digital screens. A brighter screen demands more from your eyes. Therefore, reducing the brightness to a comfortable level can decrease eye strain. Similarly, increasing the contrast can make it easier for your eyes to distinguish between different elements on the screen, further reducing strain.
Certain lifestyle adjustments can help prevent the onset of myopia. One such adjustment is increasing your outdoor time. Several studies have shown that spending more time outdoors can slow down the progression of myopia in children. The natural light outdoors and the opportunity to focus on distant objects can be beneficial for your eyes.
Another adjustment is incorporating regular physical exercise into your routine. Exercise improves blood circulation, which includes the blood flow to your eyes. This can help maintain your eye health and prevent vision problems, including myopia.
Regular eye exams are crucial in the digital age. They can help detect myopia and other eye problems in their early stages, making them easier to manage. If you're spending a lot of time on digital devices, consider getting your eyes checked at least once a year.
Navigating the impact of screen time on your eyes in the digital age might seem challenging, but with understanding, strategies, and regular eye exams, it is entirely manageable. With conscious efforts and healthy habits, you can enjoy the benefits of digital devices without compromising your eye health.
