Technology in the Classroom and the Eyes

The use of technology has become commonplace in the classroom. So much so that today’s generation of students, from kindergarten to university, navigates computers, smartphones and tablets all the time.  Many schools have even implemented the use of smart boards and bring your own device (BOYD) programs.

However, as amazing as this educational technology can be, it is important to be aware of the potential visual challenges that can arise from prolonged use of digital technology.

According to a recent study by the American Optometric Association's (AOA), 85 percent of parents surveyed said their children use an electronic device for up to four hours every day. The survey also found that 41 percent of children have their own smartphone or tablet while 32 percent use both e-books and textbooks at school. Additionally, 66 percent of children use a computer or tablet to do homework or study.

Staring at a screen for a few hours a day can cause visual discomfort and interfere with your child's ability to focus. Although regular use of digital devices won't damage vision, extended use of technology at school or for homework can lead to a temporary vision condition called computer vision syndrome (CVS). Symptoms of CVS include eye strain, fatigue, burning or tired eyes, the inability to focus, headaches, blurred vision, double vision or head and neck pain. To alleviate and prevent CVS, teach your child the 20-20-20 rule when using technology or doing near work: take a 20-second break, every 20 minutes to look at an object 20 feet away.

There are also a number of physical indicators that parents should be aware of that point to vision problems. These include squinting or covering an eye to see a screen, repeated eye rubbing and excessive blinking. If your child complains of headaches or swimming words on a screen, consistently performs below his or her potential and has challenges completing homework, it is important to schedule a comprehensive eye exam to assess whether there may be any vision problems.

In addition, your child should hold any digital device a half to a full arm's length away from the eyes and slightly below eye level. Parents should encourage children to take breaks regularly while at the computer. Kids should also use ergonomic desk areas or gaming chairs to ensure comfort and proper posture. You can prevent glare on screens by using low-wattage light bulbs, dimmers, or curtains in the room. Avoid staring at screens in a completely dark room, and adjust the brightness and background color settings on the device.  Ask for anti-reflection coatings on lenses.  New lens coatings available protect from blue light hazard.  High energy blue light is radiated by fluorescent and CFL light bulbs, computer screens, tablets, smart phones and televisions.  Blue light hazard increases risk of progression of cataract and macular degeneration over the long term. 

Usage of digital devices will likely increase as technology advances. Teach your children good habits to keep their eyes comfortable and to protect their vision. 

Thank you for trusting your eyecare with us over the years.  The Foresight Eyecare team follows the government mandate to reduce the spread of the COVID-19 pandemic.  After December 2020 announcements made by the Alberta Government, our clinic is following the revised Infection Prevention and Control policy by the Alberta College of Optometrists.

Patients interested in obtaining eye exam services or eye care products can be seen by appointment only.  Please call ahead, and staff will arrange an appointment time and ask COVID-19 screening questions.  If you have any symptoms of cough, fever, runny nose or shortness of breath, we ask that you call or e-mail us and do not attend the clinic for your scheduled visit.   Within the clinic, please wear a mask and use the hand sanitizer at reception.  Our clinic complies with the City of Calgary bylaw requiring mask covering over the age of two years old.  For patients who are unable to wear a face covering due to medical reasons, the patient can be scheduled for an appointment at a time when minimal number of other patients are in the clinic such as at the beginning or end of the day to ensure appropriate physical distancing requirements.

We are using disposable disinfectant wipes on all surfaces and devices such as front desk counters, chairs, handles in exam rooms and waiting room.  All eyewear that have been touched by patients are continually being sanitized.   Any toys and magazines are stored at this time.  Examination areas are being sanitized with hospital grade disinfectant.  Debit and credit cards but NO CASH payments will be accepted.

COVID-19 symptoms are not always obvious.  We want to fend off this pandemic and minimize risk to our patients and the Foresight staff as front line health workers.   Contact that is closer than 2 m (6 feet) is to be avoided, with barriers in place when this cannot be avoided. We choose to continue to do our work and cautiously take care of our patients with compassion, humility, gentleness, and patience.   It is a challenging and new experience for many of us, so let‘s support each other and prevent virus spread!  Beyond 2020, our focus is on take care of you and keeping Clean Hands, Clear Heads and Open Hearts.   For more information, please refer to the following web pages or phone Health Link 811.
