Presbyopia
Presbyopia is the difficulty in seeing close up that occurs as the eye's natural lens loses its flexibility with age, usually starting at around 40. Glasses are the simplest solution; contact lenses and surgery are options for suitable people.
What is presbyopia?
The eye's natural lens changes shape to focus on near objects. With age the lens loses its flexibility and seeing close up becomes harder. Needing to hold a book or phone further away when reading is a common sign.
When does it start?
It usually starts at around 40. Heavy readers may notice it in their early forties, while people who do little close work may notice it at around 50.
Long-sighted people struggle more with near vision, whereas short-sighted people can often see close up more easily by taking off their distance glasses.
Treatment options
- Glasses: the simplest option.
- Contact lenses: multifocal lenses, or monovision, where one eye is set for distance and the other for near.
- Laser: can be used to create monovision.
- Lens replacement: the natural lens is replaced with a multifocal or extended depth of focus (EDOF) intraocular lens.
The choice is made after a detailed examination, taking into account age, eye structure, occupation and expectations.
Frequently asked questions
At what age does presbyopia start?
Usually at around 40; people who do little close work may notice it at around 50.
Can presbyopia be corrected with surgery?
In suitable people, laser monovision or lens replacement can reduce the need for glasses; it is not suitable for every eye.
