Your life turns into an unending darkness. You can never see your loved ones, your children, the Sun or the Moon. It can be worse than death itself. Laser weapons can be used in the battlefield to permanently damage the eye and cause incurable blindness in everyone hit by the beam.
Guns shooting invisible rays of demise are no science fiction, unfortunately.
Very real laser rifles capable of blinding human beings exist, and have already been tested in practice. The good news is that no reports of their use in actual combat situation has been reported yet. Furthermore, if laser weapons become commonplace among armies, they will undoubtedly diffuse to terrorist groups and criminal organizations as well. If their manufacture and use are not banned as soon as possible, we might be facing an all new disastrous means of urban terrorism by the end of the 20th century.
