Switzerland’s ABC of International Humanitarian Law (2009) states:
Weapons
International humanitarian law imposes limitations, in some cases a total ban, on the use of weapons whose impact goes beyond the permissible purpose of weakening the enemy. Weapons are prohibited on the basis of three fundamental criteria: if their use inevitably leads to death; if they cause disproportionate injury or Unnecessary suffering; if they strike indiscriminately. On the basis of these three criteria a number of specific weapons have been explicitly prohibited by international conventions, including … blinding laser weapons … Some of these bans are part of Customary international law.
