Does Everyone Eventually Need Glasses?

20 Jan 2014

Even if you don’t have a refractive error such as long or short sightedness and have been lucky enough to get away without needing glasses up to your mid-forties, you’ll start to notice changes in your near vision as your eye ages (along with the rest of you!)


What Happens to Near Vision with Age

Sharp near vision is relied upon for simple tasks such as reading and writing, so if you have begun squinting or straining to make out small text, or tend to hold objects at arm’s length, then it could be a symptom of Presbyopia.


Presbyopia is a condition that affects over one billion people worldwide and is caused by physiological changes in eyes over 40. It is an unavoidable side effect of getting older and is an indication of your eyes losing their ability to focus at near distances.

Even if you already wear glasses.

If you already use glasses or contacts to correct your distance vision, then bifocals or multifocal lenses are needed to treat Presbyopia or alternatively, the PRESBIA Flexivue Microlens is an effective treatment for the condition.


What happens when I can’t see things up close?

When light enters the eye, it passes through the cornea and pupil and lens before landing on the retina at the back of the eye, which then send coded messages to the brain that allows us to see the outside world.


In young eyes, the lens is flexible and can change its shape instantly to accommodate images both near and far away. The lens is controlled ciliary muscles that constrict or relax depending on the amount of light entering the eye.


In older eyes, the lens hardens and ciliary muscles weaken meaning they are less able to change shape readily making it more difficult to focus on objects up close.


Treating Presbyopia with PRESBIA at Optilase

The Presbia Flexivue Microlens represents one the latest developments in corneal inlays for presbyopic eyes.


An implant measuring 3mm in diameter with a small 0.15mm opening in the centre is implanted in a patient’s non-dominant eye to counteract the effects of Presbyopia.


The Microlens alters the way light bends in the eye by way of its unique design – the area surrounding the central opening contains no refractive power, while the peripheral zone contains additional power ranging from +1.25D - +3.5D.


Presbia is a very effective solution to anyone suffering from Presbyopia, with the added bonus of being removable to accommodate any future increase in a patient’s prescription.
