Tests and diagnosis

By Mayo Clinic Staff

Presbyopia is diagnosed by a basic eye exam. A complete eye exam involves a series of tests. Your eye doctor likely will put drops in your eyes to dilate your pupils. This may make your eyes more light sensitive for a few hours after the exam. Dilation enables your doctor to more easily evaluate the inside of your eyes.

Your doctor may use various instruments, aim bright lights at your eyes and ask you to look through several lenses to test your distance and close-up vision. Each test allows your doctor to evaluate a different aspect of your vision.

The American Academy of Ophthalmology recommends that adults have a complete eye exam every:

  • Five to 10 years under age 40
  • Two to four years between ages 40 and 54
  • One to three years between ages 55 and 64
  • One to two years beginning at age 65

You may need more-frequent exams if you have risk factors for eye disease or you need glasses or contact lenses.
