Presbyopia Tests & Diagnosis
Routine eye exams are the best way to diagnose presbyopia and to track whether the condition is becoming worse. It is recommended that people undergo an eye exam at least once a year; however, you may need to undergo eye exams more frequently if you notice that your vision is degenerating quickly or if you need to increase the strength of your prescription so that you can continue to read comfortably.
If your vision is deteriorating at an accelerated rate, you might need additional tests to rule out more serious complications. Normally, during your annual vision exam, the doctor will check for other conditions as part of procedure.
When you go for a vision exam, your opthalmalogist will conduct a series of tests to examine the retina, test your eye muscles, and measure your ability to see. These tests will help determine what kind of prescription you need and whether you are better suited for glasses or contact lenses.
It is normal for your presbyopia to worsen over time, so you should expect to need a stronger prescription when you go for your checkup. The condition will worsen at different rates for everyone, and you may end up with different prescriptions in each eye.
For some people over-the-counter reading glasses are sufficient. Other people will need a prescription for reading glasses, bifocals, or contact lenses, especially if you have other vision conditions such as myopia. Even if you do not need a prescription, you will still need to see an ophthalmologist at least once a year. Only your doctor can tell you whether you need prescription or nonprescription lenses.
Routine Eye Exams
During a routine eye exam, the doctor will begin by asking you about your medical and vision history. Then, the doctor will take a look at your eyes to see if anything appears abnormal. After these basic assessments, the doctor will measure your visual skills, ability to see color, pupil health, and peripheral vision. The doctor will test for abnormalities.
Many doctors complete refraction tests as part of a routine examination. The doctor might also complete functional tests, which measure the eye's ability to focus. A series of additional tests are required to assess whether the eyes are in good overall health.
