What Happens During an Eye Examination

During an eye examination, several tests are conducted to evaluate the health and functionality of your eyes. These tests are crucial in detecting any potential vision problems or eye conditions.

One of the first things an eye doctor will do is check your visual acuity. This is done by having you read from an eye chart to determine how well you can see at various distances. The doctor will then use a special device called a phoropter to find the appropriate lens prescription, if needed.

Next, the doctor will examine the external and internal parts of your eyes using a microscope called a slit lamp. This allows them to assess the health of your cornea, iris, lens, and retina. They may also perform a tonometry test to measure the pressure inside your eyes, which can help diagnose glaucoma.

Another important aspect of an eye examination is checking for refractive errors, such as nearsightedness, farsightedness, and astigmatism. This is often done using a machine called an autorefractor, which provides a preliminary measurement of your eye's refractive error.

In addition to these tests, your eye doctor may dilate your pupils using eye drops. This allows them to have a better view of the inside of your eyes, including the retina and optic nerve. While your pupils are dilated, your close-up vision may be temporarily blurry and you will be more sensitive to light.

Overall, an eye examination is a comprehensive evaluation of your eye health and visual function. It is recommended to have regular eye exams to ensure early detection and treatment of any potential issues. By prioritizing your eye health, you can maintain good vision and prevent future complications.
