A 13-year-old male with attention deficit disorder (ADD) presented to the Emergency Medicine Department accompanied by his mother complaining of visual disturbance after staring into the beam from a toy laser for a few hours earlier that day.

A. Few. Hours. Check out the retinal photos in the article. It looks like eclipse damage.

If you aren’t a lecturer, why would you ever buy one of these let alone give one to a child?
