LASER SIGHT is suited for alignment work.

This type of eye protector uses a relatively low optical density filter.  This makes alignment work possible when a visible baser beam is used.  For a laser beam below 100mW, use an eye protector with OD 2, classified by adding M as product code.   For a laser beam below 10W, use an eye protector with OD 4, classified by adding A as product code.

Type Attenuation to 1/100 for "alignment work".
