quote=canopener] ..............fitness to drive doesn't start or end with eye sight; you might also consider general medical fitness, fitness or otherwise through the use of prescription or recreational drugs, alcohol etc. If you are going to provide an eye test, then what about a medicals, drug testing etc?
......... I suggest that routine provision of eye tests and medical checks etc is in most cases a step too far. .......
Whilst I agree that eye testing may normally be a step too far, its worth remembering that eyesight is only roughly checked once during the Driving Licence process.
In a previous railway construction existence [constructing HS1... - ... and don't get me started on how misguided HS2 is!] we had a 'muck shifter' driver drive into a ditch. He was in his fifties, had a clean driving licence for over 35 years and had driven the muck shifters for many years.
Unable to determine why he drove into said ditch, we eventually gave him a medical - he passed with flying colours except for the fact he was blind in one eye, so had no 'vision of depth'. So there are occasions when eye tests are beneficial, but ,I would suggest, only as part of a 'general medical'.
My rational for arranging general medicals is that it is beneficial for the individual as well as the company, however they must normally be optional, unless part of the contract of employment, or as a part of an accident investigation
