Eye examinations are primarily performed to detect visual impairment or eye conditions. An eye examination can detect eye diseases such as glaucoma and cataracts, systemic diseases like diabetes and hypertension, and neurological conditions such as stroke.

Types of Eye Examinations

There are several types of eye examinations, including:

• Visual Acuity Test: This test measures the eye's ability to see details at near and far distances. The test may involve reading letters or looking at symbols of different sizes on an eye chart.

• Visual Field Test: This test measures your side (peripheral) vision. It helps your eye care professional tell if you have lost peripheral vision, a sign of glaucoma.

• Dilated Eye Exam: In this test, drops are placed in your eyes to widen, or dilate, the pupils. This allows your eye care professional to see more of the inside of your eyes to check for signs of the disease.

• Tonometry: This test helps to detect glaucoma by measuring eye pressure. Your eye care professional uses a device called a tonometer to measure the pressure in your eye.

Importance of Eye Examinations

Regular eye examinations are important because they often identify eye abnormalities before symptoms may appear. Eye examinations are crucial for detecting diseases early and preserving vision.
