All

That many choices of safety glasses out there on prescription what is adequate and what is not.

Is the best option to go with the Complete safety glasses with the Pentax CR 39 for our employees that are required to wear safety glasses at work?

Thanks

That would all depend on your business. We use Specsavers but always opt for the Polycarbonate lenses which cost extra but are more scratch resistant. We are a manufacturing business with machinery and manual processes such as fettling and grinding and the CR39 are simply not good enough. They are strong enough but get damaged too quickly.

We are a waste recycling company and have many different process ongoing in all areas, The information that you have provided has been helpful and will help me differentiate between our maintenance staffs choice of glasses and our floor staff.

Thanks

Be aware if you "just" order safety specs from specsavers (I've no reason to assume other suppliers are different) they are (unless you specify and pay extra) low impact grade and IMHO not sufficent for use in an engineering environment.

I appreciate thats not what the OP asked.

Another vote for polycarbonate here, it also depends on your risk assessment; our site minimum for safety wear is EN 166 F - CR39 does not meet this spec.

Another consideration is regarding glasses use - in a laboratory environment polycarbonate will give your low energy impact protection, but it damages very easily with some chemicals which will weaken the lens.
