- Visual Acuity Test
This test is what every person probably thinks of when he pictures himself at an optometrist.

A refraction test helps in the determination of an eyeglass prescription. A person is required to gaze into a phoropter and stare at the eye chart present on the opposite wall of such a vision test. Through the test, he will be able to see various lens pairs.
The eye doctor will ask you repeatedly as to which of the two given options of lens you wish to prefer over the other. Based on the answers given by you, he will determine whether your vision is affected by astigmatism or your eyes are farsighted or nearsighted. You can also know if you do not need a prescription for vision correction.
