Lockdowns Damage Children's Eyesight: Too Much Screen Time, To Little Outdoors Time

 "Lockdowns” aka Imprisonment: Harmful, Damaging in oh so many ways....

• Lockdowns Increased Nearsightedness in Children= Long Term Harm to Eyes

 More Lockdown Harm (Cause that’s the REALITY)

"The researchers also found “significant changes” in the children’s lifestyles during Covid restrictions; outdoor time decreased by 68 percent, and screen time increased 2.8-fold.   

“An increase in outdoor time has been consistently shown by multiple studies in different countries to have a protective role against the development of myopia, and is a top priority among international recommendations for myopia control strategies,” Yam said."

Outdoor time excellent for eyes. Lockdown restrictions resulting in increased screen time = eye damage

The Study

An analysis of eye test data from nearly 2,000 Hong Kong school-age children revealed that the rate of nearsightedness that developed during the pandemic (LOCKDOWNS)  more than doubled what was found in a pre-pandemic study of children the same age, according to the report in the British Journal of Ophthalmology.

The researchers also looked at how much the axial length — measured from the cornea to the back of the eye — was changing over time. In children with progressive nearsightedness, the axial length increases as children age, so that if the eye could be viewed in profile it would look more oblong than circular. The annual estimated change in axial length among children during the pandemic was 0.45 millimeters

“When people think of consequences that this unprecedented level of quarantine has on physical and mental health, it is not initially obvious that children’s visual development is one of them,” a co-author of the study, Dr. Jason C.S. Yam, an associate professor of ophthalmology and visual sciences at the Chinese University of Hong Kong, said by email.

“Our study showed that less time spent outdoors and more time spent on near work, including screen time, is associated with faster progression in short-sightedness, or myopia," Yam said.

While myopia may seem like an innocuous condition, it can predispose people to other ocular complications and increased risk of vision loss later in life, he said.

Animal studies have suggested that outdoor light helps protect against myopia by sparking “an increase in dopamine release in the retina, which inhibits elongation of the eyeball,” Yam said.
