I don't know why you are asking for a template, if you assess the risk, then put corrective actions in place, do they need to wear safety glasses, yes or no

I agree with previous two posts and would also suggest a look at the Personal Protective Equipment Approved Code of Practice: it has straightforward guidance. PH2

Even with normal light eye protection it is possible to get small particles of grit/dirt in the eye, especially in dusty environments like construction sites. That said, one could be walking down the street and get something in the eye from passing traffic or whatever. Do we accept this or are we saying that maximum protection must be applied at all times?

Epideave. The "let's all wear eye protection whether we need it or not" idea is very common in the US (do you work for a US-run company?) and personally I don't find it very helpful. I think it devalues PPE to force people to wear it just because someone thinks everyone should do it rather than because there is a real risk of eye injury. In your shoes I'd be listing all the relevant tasks on site and looking at the actual risk of eye injury on each (use severity and likelihood matrix or whatever other mechanism you usually use for assessment rating). Then assign the correct protection to each task as others have already said. Template could be a simple table - Task, hazard, risk presented by that hazard, assessment of magnitude of risk, type of PPE recommended, other action required to reduce risk. Doesn't need to be anything fancy.
