Reading gets harder with age because of presbyopia, a normal change in which the lens inside the eye gets harder and less flexible. The National Eye Institute (NEI) says everyone gets presbyopia as they get older, usually after age 45. [1] Reading glasses, other glasses or contact lenses can correct it. [1][2]

At a glance

When it starts
Usually after age 45, according to NEI. [1]
Common signs
Trouble seeing up close, holding things farther away to read, and eye strain. [1]
Does it get worse?
Yes, over time. It usually stops getting worse after age 65. [1]
Correction
Reading glasses, bifocals or progressives, contact lenses, eye drops or surgery. [2]

What is presbyopia?

When you are young, the lens of your eye is soft and flexible. Tiny muscles inside the eye change its shape so you can focus on things near and far. [3]

With age, the lens hardens. Aging also affects the muscle fibers around the lens. The eye can no longer focus light from close objects onto the retina (the light-sensing layer at the back of the eye), so nearby things look blurry. [3]

Presbyopia is a normal part of aging, not a disease. [1] The name comes from a Greek word meaning “old eye.” [2]

It is different from farsightedness, which also makes close objects blurry but comes from the shape of the eye. [1] You can have presbyopia along with another refractive error, such as nearsightedness. [3] See our guide to nearsighted vs farsighted.

Signs and symptoms

NEI lists these signs: [3]

  • a hard time reading small print
  • needing to hold reading material farther away
  • problems seeing objects that are close to you
  • headaches
  • eye strain

The AOA adds that print may look blurry in dim light, such as on a restaurant menu. You may also need more light to see as well as you used to. [4]

Sources describe the timing a little differently. NEI says presbyopia usually appears after 45. [1] The AAO says you may notice it shortly after 40, and the AOA says it often begins in the early to mid-40s. [2][4]

Will it get worse?

Presbyopia gets worse over time. NEI says it usually stops getting worse after age 65. [1] The AOA says changes in near vision should stop around age 60. [4] Until then, you may need new glasses more often than before. [4]

It cannot be prevented or cured. But most people can get clear, comfortable near vision again with the right correction. [4] If you leave it uncorrected, you may get headaches and eye strain. [2]

How presbyopia is corrected

In the early stages, simple changes can help: hold reading material farther away, use large print or a bigger font, and use brighter reading lights. [1]

As it progresses, most people need glasses or contact lenses for reading. [1] Options the AAO describes include: [2]

  • Reading glasses. These can be bought without a prescription, but the AAO says an eye doctor should determine the power you need. [2]
  • Bifocals, trifocals or progressive lenses. These are for people who also need glasses for distance. They have different focusing powers in different parts of the lens. [2]
  • Contact lenses. Monovision lenses correct one eye for distance and the other for close up. Multifocal lenses have zones set at different powers. [2]
  • Prescription eye drops. These make the pupils smaller, which helps the eyes focus up close. They last up to six hours and are used every day. [2]
  • Surgery. Options include laser surgery for monovision or replacing the eye's lens with an implant. [2]

Eyeglasses are the simplest and safest way to correct presbyopia. [3]

When to see an eye doctor

Get urgent help now if

  • You suddenly see more floaters than usual, along with bright, flashing lights. The AOA says to see your eye doctor immediately, because this could be a sign of a retinal tear. [4]
  • A dark shadow or “curtain” appears over part of your vision. NEI says possible signs of retinal detachment need your eye doctor or the emergency room right away. [5]

In the US, call 911 or go to the nearest emergency room. In other countries, call your local emergency number.

Make a routine appointment if

  • You have any of the signs above. NEI suggests seeing an eye care professional for a comprehensive dilated eye exam. [3]
  • You already wear glasses or contacts and still have trouble seeing up close. You may need a new prescription. [3]
  • Your vision keeps changing. The AOA says frequent changes in how clearly you see may be a sign of diabetes or high blood pressure. [4]
  • You are 40 and have not had a baseline eye disease screening. [6]

An optometrist or ophthalmologist can check your eyes and tell you what is right for you.

Common questions

At what age does presbyopia start?

NEI says everyone gets presbyopia as they get older, usually after age 45. The AAO says some people notice it shortly after 40. [1][2]

Is presbyopia the same as farsightedness?

No. NEI says presbyopia is different from farsightedness. Presbyopia comes from the lens hardening with age. [1]

Are drugstore reading glasses OK?

NEI says reading glasses can be bought without a prescription and can help with reading. The AAO says an eye doctor should determine the power you need. [3][2]

Can presbyopia be prevented?

No. The AOA says presbyopia can't be prevented or cured, but most people can regain clear near vision with correction. [4]
