Interesting question. It appears that safety glasses in this instance are not a suggestion but a requirement. I would ask you if this is a reoccurring problem with the student or a one off situation. If this has occurred more than once, a warning of a potential credit loss was given, and you have a policy in-place. Then I would say yes.
It is difficult without knowing all the particulars of your School, the setting and expectations, but the reality is the loss of a credit if far less important then that of eye sight.
Please Ronald, Let me know… >>>
