Computers and other kinds of electronic devices have become an integral part of every individual’s life. The devices help us learn, keep in touch with friends and family and provide efficient execution of activities.
However, an eye doctor in London warns of the health risks of prolonged exposure to the electronic devices. Studies show that adults who spend more than six hours glued to their screens have a higher chance of developing a condition known as eye fatigue. More young children are also being diagnosed with the problem as they are likely to acquire digital devices at an early age.
Common symptoms of digital eye strain include blurry vision, dry eyes, headaches, problems focusing, red and irritated eyes. Digital devices emit blue (high-energy visible) light. The light has short wavelengths that radiate high energy and cause deep penetration, resulting in sleep problems, damage to the retina and long-term vision problems like cataracts and age-related degeneration. HEV light has also been associated with eye pain and headaches when digital devices are used before bedtime.
Unlike other problems, electronic eye fatigue develops among people without a history of vision conditions. Eye doctors recommend natural methods to reduce electronic eye strain and improve eye health.
Taking Breaks from Electronic Devices
Taking a 20-20-20 break where you stand, walk or stretch after every twenty minutes for twenty seconds and look at something twenty feet away. Move around the workplace or home, take a nap or short meditation; anything to reduce the eye strain helps soften your gaze and regain focus.
Perform Various Eye Exercises
Performing soothing eye exercises minimise the symptoms of eye fatigue. Effective eye exercises include rotational viewing, palming, sideways viewing and making near and distant observations. Palming exercises help revitalise the eye muscles and stimulate the circulation of aqueous humour while rotational viewing improves coordination and balance in the muscles around the eyes.
Blink More Often
Blinking moistens the eyes to prevent irritation and dryness. People blink less when using digital devices. In fact, studies show that most blinks that are performed when using the devices are only partial lid closures. Tears coating the eyes fade away more rapidly during the extended period of non-blinking phases, causing dry eyes. Your eye specialist might recommend blinking ten times after every twenty minutes by closing your eyes for prolonged periods to help rewet the eyes.
