Laser pointers can cause irreversible vision loss for kids

Used incorrectly, laser pointers can damage the retina of the eye and may cause some irreversible vision loss, according to researchers who treated four boys for these injuries.


Doctors, teachers and parents should be aware that this can happen, and limit children’s use of laser pointers, the authors write.

He advises parents to be careful about where they buy laser pointers, as some retailers may not list the power rating or may list it incorrectly, and to limit use for kids under 14.
Most consumer laser pointers fall under class II or class IIIA level of safety according to the American National Standard Institute, with a power output of five milliwatts or less. But class 3B or class 4 level lasers may emit up to 500 milliwatts or more and these lasers may cause immediate eye hazard when viewed directly, Almeida and his coauthors write.

Retinal tissue in the back of the eye leads to the brain, and it has no ability to regenerate after tissue loss, Almeida said.

“Unsupervised use of these laser pointer devices among children should be discouraged, and there is a need for legislation to limit these devices in the pediatric population,” he and his coauthors write.
