safety glasses for visitors

[mdater@nexstar.com (Mark Dater)]

Good morning,
Does anybody out there have a line on truly disposable(throwaway) safety 
glasses for visitors just walking through a facility? Do you think these 
type adaquate or should visitors be given full (industrial strength)  safety 
glasses for a visit (walkthrough)? You may reply to me, E-mail.
Thank you,
