The World Federation One Stop Fiqh

Ruling 2460

If a person is compelled to look at someone’s private parts to treat him, then based on obligatory precaution, he must place a mirror opposite [the person’s private parts] and look [at his private parts] through the mirror. However, if there is no other way but to look directly at his private parts, there is no problem. The same applies [i.e. there is no problem] if it would be quicker to look directly at the private parts rather than look at them through a mirror.
