Where your risk assessment indicates that eyr protection is necessary and the concerned workers need prescription glasses, then I would strongly recommend that the employer supply prescription safety glasses. Asking an employee to wear "coverall" safety glasses over his own glasses can be done but it is not comfortable for the employee and they have a tendancy not to wear the "coveralls".

Ditto, Ditto. From experience, company implemented Mandatory eyeprotection policy. One employee (process operator)presented prescription that stated he requires reading glasses. Co. refused to supply prescription safety specs. Employee wears co. issued safety specs, then removes them to put on his own specs whenever he needs to read something, then replaces safety specs.

C'mon... surely you can see it coming already??? Yep, you guessed it during this "changeover" ritual while fitters were working in the area, employee got foreign body in eye, later determined as a sliver of metal from fitters using impact wrench. Nearly lost use of the eye.

PS. Co. issued him with prescription safety specs after accident.. Nice of them, hey??!!

Since the original question concerned quite specifically safety glasses, we were keeping it simple. Chemical goggles, full and half masks or BA sets will of course complicate the problem. You may eventually ask yourself if the employee is medically fit to do the job. Or even try to engineer out the risk. Wouldn't that be a good idea ?
