Presbyopia
There is a gradual deterioration in the ability of the eyes to focus, as we get older. Symptoms generally appear in the forties and sometimes tiredness and headaches occur more often.

At this stage some help is reqquired in the form of reading glasses, or for those who already wear spectacles, there are multi-focal and progressive lens options.

It is a normal stage in ageing. A pair of suitable precription eyewear is helpful.
