Eye doctors use a wide variety of tests and procedures to examine your eyes. These tests range from simple ones, like having you read an eye chart, to complex tests, such as using a high-powered lens to visualize the tiny structures inside of your eyes. Regardless, when you have an eye exam, it will usually take anywhere from half an hour to an hour or more, depending on the doctor, his or her caseload and the number and complexity of tests required for your eyes.
Here are the basic tests that you are likely to encounter during a routine eye exam
(your doctor also has dozens of less routine ones at his or her disposal):
- Retinoscopy
- Refraction
- Autorefractors and aberrometers
