At some point, everyone will experience presbyopia. This universal refractive disorder is a normal consequence of the aging process. Over time, your eye’s natural lens will begin to harden and become inflexible, making it difficult to focus on close-up objects. Presbyopia is the reason why people over the age of 40 typically need reading glasses or bifocals.
Ideally, the natural lenses in your eyes should be soft and flexible, allowing them to easily change shape whenever you need to focus on different objects at different distances. This natural focusing ability is called “accommodation.”
As you age, however, the proteins in your lenses will become stiffer and less flexible, limiting your eyes’ natural ability to accommodate. When this happens, close objects will become increasingly blurry and out-of-focus, making it difficult to read and see fine details.
Bifocals vs. Reading Glasses
If you already wear glasses for another refractive error (such as myopia, hyperopia, or astigmatism), you will most likely be prescribed with bifocals to correct presbyopia. The double lenses in bifocals correct your regular prescription along with presbyopia.
If you wear contact lenses – or if you never needed corrective lenses in the past – you should only need basic reading glasses to treat presbyopia.
