Do I need glasses ?

From an optometrists point of view one of the most frustrating things regularly occuring in practice is the patient attending for an eye examination - we meticulously go through the examination procedure and arrive at a prescription which gives that individual better,improved visual clarity. The patient is advised that they need to wear the prescription and they say ' But my vision is fine - I don't need glasses'.

I kind of thought that was the reason they came to see me in the first place ??
