These days we are staring almost all day long at different types of digital screens and because of that we are more and more exposed to the damaging blue light (high-energy visible light \ HEV) that can influence our sleep, productivity and even our vision. From the moment we wake up in the morning, we check our phones, then at the office we stare at a computer screen for at least a few hours and finally when we get back home to relax in front of another screen regardless of whether it is a TV, tablet or computer. For example, a graphic designer spends at least 8-9 hours each day in front of a computer screen. Although we often realize that these screens are affecting us to some extent, few are the ones who take action to protect their eyes.
A back or shoulder pain from a wrongly chosen chair or a tired liver from too many hours of work can be treated relatively easily, but a damaged eye is much more complicated to be treated and involves many risks. The eyes problems caused by digital screens are called by specialists the “Computer vision syndrome” or “Digital eye strain” and symptoms may include blurred or double vision, light sensitivity, dry eye, fatigue and headaches. Although many times it is presented as a common condition and rarely serious, some studies suggest that bright light and blue light can damage your retinas irreversibly. Longer exposure to blue light could lead to age-related macular degeneration.
Just a few simple steps can help us to prevent or at least ease this problem.
