Presbyopia is the loss of clear close-up vision that occurs
naturally as people get older.
How does it occur?
Around the age of 40, the lenses of your eyes begin to lose
elasticity and flexibility. You may find that you are
unable to focus sharply on close objects. You may need to
hold things farther away from your eyes to see them clearly.
What are the symptoms?
Presbyopia develops gradually. At first you may have
blurred vision when you read or do close-up tasks such as
threading a needle. Later you may not be able to read
normal newsprint or book print without reading glasses or a
magnifying glass and good lighting.
How is it diagnosed?
Your eye doctor can verify your condition during a regular
visit.
How is it treated?
There is no treatment that can make your lenses flexible
again. However, reading glasses, bifocals, trifocals,
progressive lenses (no lines), and possibly contact lenses
can help you see close-up objects. Recently, refractive
surgery has also been used to correct presbyopia. Discuss
these options with your eye doctor.
How long will the effects last?
Presbyopia is a permanent change that tends to worsen very
gradually over time.
What can be done to help prevent presbyopia?
There is no known prevention, however you can help protect
your eyes and vision. Have your eyes checked regularly and
schedule an appointment with your eye doctor if you notice
any changes with your eyes.
