A new study on nearsightedness in Canadian children has revealed a big jump in this condition between grades 1 to 8. The research tells of a fivefold increase in cases in this timeframe for schoolchildren, noting that a third of cases are believed to be undiagnosed and therefore uncorrected.
“Myopia, or nearsightedness, occurs when the eye grows too long and causes light rays to focus at a point before the retina. Close objects look clear but distant objects are harder to distinguish and appear blurred.” University of Waterloo
The research team, from the University of Waterloo and CNIB, noted that myopia rises from just 6% of children ages 6 to 8 to nearly 29% in children ages 11 to 13. In fact, the World Health Organization (WHO) has noted that myopia is “increasing globally at an alarming rate” and can add more pressure to the risks for vision impairment. With myopia appearing earlier in this generation’s children, these individuals may be at risk for a greater decline in eyesight over the course of their lifetime. Retinal degeneration and detachment are two complications that arise from myopia.
