Myopic changes in 8-25 year olds during 2020

Updated: Aug 30

I was interested to see the impact of 2020 lockdowns and remote learning on the eyes of 8-25 year olds. Once we exited lockdowns late 2020 I started tallying up the myopic changes of the individuals coming in for their eye tests. (note: children tallied were previously myopic prior to 2020 to monitor progression and data was only for Edithvale store)


8-12 year olds


The largest change noted in this age bracket was -1.00 Dioptre, which signifies 4 steps of myopic deterioration. 22% of children showed no change


13-18 year olds


70% of teenagers showed up to 1.00 Dioptre change. 25.9% showed no change in myopia.


19-25 year olds


The most surprising age group. 81.8% had no change to their vision status. 18.2 % has minimal myopic change of 0.5-0.75. There were no 1 Dioptre or 2 Dioptre shifts in vision. Even with all the study/computer work that must have been done, there wasn't significant changes to myopia. This also corresponds to the optimum age of 25 for laser eye correction, as one would want to have more stable vision prior to the procedure.
