So the 9 year old said he only looked into the laser for 2 seconds...........
Is that 1 second per eye ?
The doctor was amazed at the amount of damage.
Did the boy blind 1 eye then decide to blind the other? Was the damage immediate I suppose would be another question.
I bet he looked into it a lot, several times for longer each time and then watched the colors afterwards until finally he went too far, he may have been seeing spots all day, I don't believe this 2 seconds BS and I bet the Chinese seller thought that nobody would stare into one of these.
Would a 9 year old hold a magnifying glass up towards the sun and look at it ?
I played with magnifying glasses when I was very young, I used to burn leaves and pine cones, pine straw ect....
I knew better than to hold the glass between the sun and my eye, nobody had to tell me that, and I knew not to ride my bike out in front of traffic, well I was told not to.
Anyway the boy was told not to do it yet in ( 2 seconds ) blinded both eyes ?
No I doubt that, I watched a 16 year old on you tube shine a cheap greenie into both his eyes on purpose for the purpose of making content for his youtube channel, he had to force himself to hold his eye open, that is he had to noticeably and audibly fight against his blink reflex, I would bet the 1st time the kid shined it into his eye he blinked, he would had to have worked his way up to even ( 2 seconds ), I bet he was watching the colors from doing this over and over.
---EDIT---
My parents used to tell me " Don't stare into the sun or you'll go blind " and I would take a glimpse anyway, but not for more than a half second, maybe 1 second at the most and I was very young, maybe 9 years old......1st grade I was 6 years old so 9 years I would have been in 4th grade.......I bet a certain number of children do stare at the sun and receive damage every year, who's fault is that when the parents tell them not to do it ?
Why don't babies in a stroller go blind from staring at the sun ? How about 4-5 year olds who are playing in the kiddie pool during the hot summer months, I think the reason parents tell us " Don't stare at the sun " is because they see us looking at it, kids who stare into the sun may get damage, when they do I bet they say " I only looked into the sun for 2 seconds "
