Parenting and controlling screen time go hand in hand if you have a teenager these days. The fact is, young millennials and generation Z were born into the instantly accessible world of laptops, tablets, and smartphones to the point that many toddlers know how to work digital devices better than their parents. With the constant use of technology spread out between entertainment, education, and socializing with friends, teens are on tech devices now more than ever.
Reports indicate that Canadian teens spend an average of eight hours in front of a screen per day. In a national survey of 52,000 Canadian kids between Grades 6 and 12, more than 50% get more than two hours of screen time each day. Boys averaged slightly more screen time at 8.3 hours per day, while girls found themselves focused on screens for 7.3 hours. That’s a lot of hours, considering the recommended national guidelines for the amount of screen time for children aged between 5 and 17 is two hours per day.
Even if excessive screen time may not be the root cause of severe eye-related complications, it can put pressure on a teen’s growing eyes. Read on to find out how your teen’s eyes could be affected.
Refractive errors are common among teens who dedicate a lot of time to device use. Although 60% of refractive errors or nearsightedness, also known as myopia, are caused by hereditary factors, recent studies have shown that prolonged hours of device usage worsen nearsightedness.
Viewing a screen for long periods of time or holding a small device close to your eyes can cause your teen to experience a tension headache. Quite common amongst people of all ages, the headache is your body’s response to stress on the eyes. Hectic lifestyles and stress are also commonly associated with headaches.
Computer Vision Syndrome (CVS)
A “new age” disease, CVS affects teens and middle-aged computer users who work for long hours in front of a computer screen. Symptoms include eye irritation, blurred vision, head and neck pain, as well as dry eyes caused by reduced blinking.
Lack of focus
Liquid crystal displays (LCD) and light-emitting diode (LED) displays frequently found in computer monitors, tablets, TVs, and mobile phones emit diodes of blue light that make it difficult for your eyes to focus. Muscles inside your eyes change shape when you attempt to focus. When you stare at a single point for a long time, those muscles start to weaken. In extreme cases, eye muscles can become so tired they are no longer able to focus.
Other complications linked to excessive screen time are teen obesity and poor posture.
