Smartphones, tablets and laptops are an intrinsic part of life in the 21st Century. While these digital devices have certainly helped make life more convenient, there are some downsides, including potential harm to your eyes that can occur with overuse of these gadgets. Read on as your reliable optometrist explains how spending extensive periods of time on electronic devices can impact your eyes.
What Is Blue Light?
The light spectrum consists of electromagnetic rays that have varying energy wavelengths and frequencies. The red rays are on one end, with lower energy levels and longer wavelengths, while the blue rays are on the other end, emitting higher energy frequencies with shorter wavelengths. Smartphones, laptops and other digital devices emit blue rays.
What Is Computer Vision Syndrome?
Your expert optometrist explains that blue rays can penetrate deeply into your eyes, potentially causing eyesight problems. In fact, studies show that overuse of blue light–emitting gadgets leads to computer vision syndrome. Also referred to as digital eye strain, this condition is marked by visual discomfort after extended use of an electronic device. Your eyes may feel fatigued, dry and irritated. You may also experience headaches.
How Can I Prevent Blue Light–Related Problems?
In this digital age, it’s hard to avoid the use of electronic devices. However, even if you can’t limit your use of these gadgets, there are measures you can take to protect your eyes. Always follow the advice of your trusted optometrist to observe the 20-20-20 rule. After every 20 minutes of time spent on an electronic device, look at an object 20 feet away for 20 seconds. Make sure to blink your eyes regularly as well to prevent dry eyes.
We can also help you find eyewear with blue light–protective features. They are specifically designed to block blue rays from entering your eyes, maintaining your visual health and comfort. Most importantly, remember to have regular eye exams.
