Presbyopia comes to us all!

Presbyopia is part of the natural ageing process of our eyes and starts to affect most of us in our early forties. The crystalline lens in the middle of each eye, responsible for focusing on things close-up, becomes progressively less flexible and unable to focus properly. This usually first presents as a difficulty in reading small print, holding the print further away to focus (“arms aren’t long enough” syndrome) or the need for brighter light when reading.

There is no cure for presbyopia, but there are solutions! Simple reading glasses can be prescribed. Care should be taken with over-the-counter readers though - the prescription will be the same for each eye, astigmatism won’t be corrected and the centre of the lens may not match the eyes perfectly. Prescribed glasses are made-to-measure so the frames and lenses will be fitted professionally. Bifocals or varifocals can be better options if a distance correction is also required. Bifocals have a visible line on the lens, separating the distance and near powers. Varifocals are the most popular option nowadays due to the fact they have many powers to allow focusing at many different distances but with no visible line. Trifocals are rarely used - they have 2 lines separating three powers.

Contact lenses are another popular choice with options available for daily, two weekly or monthly disposables. Monovision, where one eye is corrected for distance and the other for reading, is another option and although it sounds strange it can be surprisingly effective. With all options, whether it’s glasses or contact lenses, it may take a few weeks for the brain to adapt.

As always, if you notice any changes in your vision, you should have an eye examination to identify the exact cause.
