Reading glasses ahead: what presbyopia is and what you can choose
Last updated: 20 August 2026
It starts with the menu that needs holding a little further away, small print demanding more light, and arms that seem 'too short'. Presbyopia — age-related farsightedness — happens to literally everyone. That makes it no disease, but it is a decision point: there are more solutions than ever, each with honest pluses and minuses.
In short
- Presbyopia arises because the eye's lens stiffens with age until near focusing no longer works.
- It happens to everyone, usually noticeable between 42 and 48, stabilising around 60.
- The ADD on your prescription is the extra reading power on top of your distance correction.
- Options: reading glasses, multifocal glasses or lenses, monovision — each with its own adjustment profile; there is no 'best', only a best fit.

Why everyone gets a turn
Inside your eye sits a clear, flexible lens that bulges when you look at something close — that is how the eye focuses at reading distance. This lens keeps growing throughout life and stiffens as it does. Somewhere between 40 and 50 the flexibility has dropped so far that reading distance slips out of reach. That process is presbyopia, and it is not wear from reading, screens or 'spoiling your eyes' — it is the most democratic property of the eye: everyone, everywhere, always.
The nearsighted often notice it later or differently (glasses off, reading works fine); the farsighted notice it earlier. But the lens itself spares no one.
What does the ADD on your prescription mean?
On a prescription, the reading correction appears as ADD (addition): the extra power added to your distance correction for reading distance. An ADD of +1.50 with a distance power of -2.00 therefore means: reading with -0.50. The ADD grows gradually with age, from about +0.75 at the start to roughly +2.50 around sixty, then stays nearly stable. That also explains why reading glasses need 'topping up' a few times in the first fifteen years — after that the stretch is gone and little changes.
The options, honestly compared
Separate reading glasses are simple, cheap and optically the sharpest solution — but they go on and off, and distance vision through them is blurred. If your distance vision is still sharp, ready-made readers from the chemist are fine to try; note they carry the same power in both lenses and no cylinder correction, so with unequal eyes or astigmatism a fitted pair is more comfortable.
Multifocal (progressive) glasses are the all-rounder: one pair for everything. The honest flip side: the reading zone sits low and is narrower, the edges show some distortion, and the brain needs days to weeks to adapt. Most people adapt fully; a small group keeps noticing the edge distortion.
Multifocal contact lenses divide far and near optically across the pupil. They give freedom without glasses, but the compromise is visible: contrast is a touch lower and night vision can show halos. Monovision — one eye for distance, one for near, with lenses or laser — works surprisingly well for some, but costs some depth perception; always trial it with lenses before anything definitive.
Finally the surgical route: during cataract surgery (or lens replacement without cataract) a multifocal artificial lens can make reading glasses largely unnecessary. Here too: freedom gained, contrast and night vision traded — a decision to make with a specialist.
What is sensible
Start with a proper measurement, not a guess: the right ADD and a correct distance prescription make every option better. Then choose based on your day: a heavy reader chooses differently from a frequent driver or athlete. And give multifocals a genuine adaptation period — two weeks of daily wear says more than two evenings of trying.
Frequently asked questions
Will I become dependent on reading glasses if I wear them a lot?
No. The lens stiffens at its own pace, glasses or not. What does happen: you get used to comfort, so the situation without glasses stands out more. That is habituation, not deterioration.
Do eye exercises help against presbyopia?
No. Presbyopia stems from the stiffness of the lens itself, not weak muscles. Exercises cannot restore the focusing range; no study convincingly shows otherwise.
Why is my distance vision worse through my first reading glasses?
Reading glasses are made for 35–45 centimetres. Look through them at anything further and the image is blurred by definition. That is optics, not a wrong prescription — though a multifocal lens can solve it.
My eyes differ in power. Can I use ready-made readers?
Preferably not as a permanent solution: ready-mades have identical powers left and right and no cylinder. For occasional use they are fine; for daily reading a fitted pair almost always pays off.
