More and more children are at risk of suffering from a health problem called Computer Vision Syndrome (CVS) as technology is increasingly used in classrooms.
Eye strain, blurred vision, loss of focus and attention, neck pain, double vision, and headaches are the known symptoms of CVS.
This condition happens because computer screens make the eyes work harder. Computer screens give off glare and require the eye to look closely at images that are not as clear as those on paper. In addition, reading on the computer makes eye coordination difficult because computer screens are usually positioned a little higher than the normal reading position.
Thirteen-year-old Casey Connelly who suffers from CVS says she often get “tired eyes” as most of her school work involves computers and electronic tablets. Some schools in the US are now using electronic devices not only for typical activities like typing but also for more advanced function such as storing text books.
This set-up requires students like Casey to work longer with computers. The American Optometric Association (AOA) says that people who spend more than two continuous hours on the computer every day are most likely to develop CVS.
To avoid vision problems, Dr. Andrea Thau from AOA suggests taking a 20-second break every 20 minutes spent on the computer. Other tips include positioning the computer screen four to five inches below eye level and blinking often to keep the eyes from getting dry. An annual eye exam before the school year starts may also help students avoid CVS.
