Fortunately, more powerful lasers are much more expensive than pointers and are not designed to be portable. Press reports of corneal injuries from laser pointers are misleading. There is no significant absorption of visible laser light in the cornea, so there is no potential for corneal trauma.

The press has erroneously attributed painful vision loss from a corneal abrasion to laser pointer exposure rather than a victim's response to it.
