Holding the Menu Farther Away? What Changed in Your Eyes After 40
What presbyopia is, why it happens to almost everyone, and how to think about drugstore reading glasses.

It has a name: presbyopia
Maybe you have caught yourself holding the menu a little farther away, or tilting your phone toward the window for more light. This change has a name. It is called presbyopia.
The National Eye Institute (NEI) describes presbyopia as a normal part of aging. It is a type of refractive error that makes it hard for middle-aged and older adults to see things up close.
The NEI says everyone gets presbyopia as they get older, usually after age 45. The American Academy of Ophthalmology says you may start to notice it shortly after age 40. So if your arms suddenly feel too short, you are in very large company.

What changed inside your eye
The NEI explains it simply. As you age, the lens in your eye gets harder and less flexible, and it stops focusing light correctly on the retina, the layer at the back of the eye. That makes nearby objects look blurry.
MedlinePlus says the lens has to change shape to focus on close objects. Its natural elasticity, or stretch, slowly decreases with age, so the eye slowly loses its ability to focus on nearby objects. The Academy notes that after age 40 the lens becomes more rigid. Picture a camera lens that used to zoom easily and now moves a little stiffly.
This is not the same as farsightedness. The NEI says presbyopia is different from farsightedness, even though both make it hard to see things up close.

The signs most people notice
The NEI lists trouble seeing things up close, needing to hold reading material farther away to focus on it, eye strain, and headache. MedlinePlus lists a weaker ability to focus on near objects, eyestrain, and headache.
Many people notice it first with small print: a restaurant menu, the label on a jar, a text message.
There is some good news in the NEI description. Presbyopia gets worse over time, but it usually stops getting worse after age 65.

What helps early on
The NEI suggests simple changes first: holding reading material farther away, choosing large-print books or a bigger font size on your computer, and using brighter reading lights. MedlinePlus agrees that early on, holding material farther away, using larger print, or adding light may be enough.
A brighter lamp by your reading chair is an easy place to start. As presbyopia gets worse, the NEI says you will probably need glasses or contact lenses to help you read.

Drugstore readers or a prescription?
The NEI says some people use over-the-counter reading glasses, or your eye doctor can prescribe lenses to help you see as clearly as possible. The American Academy of Ophthalmology says that if you have no eye disease and you see well at a distance without glasses, ready-made readers from the drugstore can be enough.
Ready-made readers are one-size-fits-all. The Academy says that if you have a different prescription in each eye, nearsightedness, or astigmatism, ready-made glasses may not meet your needs. In that case, an optician can make custom lenses based on your prescription, including the distance between your pupils.
The Academy also says you would need an ophthalmologist if you wear glasses for distance, have astigmatism, or have another eye disease. And even for a ready-made pair, it says the specific power you need should be determined by an eye exam.

Why the exam still matters
The Academy says it is important to get a comprehensive eye exam by age 40, even if you have no symptoms or known risk factors for eye disease. That exam sets a baseline for the years ahead.
The NEI adds that many eye diseases do not have any warning signs, so you could have an eye problem and not know it. Reading glasses help with small print. They do not look at the back of your eye.
The Academy is plain about one thing: there is no way to stop the normal aging process that causes presbyopia. MedlinePlus says the same. But the Academy says presbyopia can be corrected with eyeglasses, contact lenses, medication, or surgery. Ask your eye doctor which of these fit your eyes.

Write your answers down, or bring this list to your next visit.
- Are my two eyes the same, or do I need a different power in each?
- Do I have astigmatism or a distance prescription that makes ready-made readers a poor fit?
- Is this just presbyopia, or is anything else going on in the back of my eye?
- How often should I come back?
