What Happens During an Eye Check-Up?

An eye check-up is a comprehensive process designed to evaluate your vision and detect any underlying eye conditions at an early stage. Many people assume that an eye exam only checks whether they need glasses, but it actually goes much deeper than that. A standard eye examination begins with a visual acuity test, where you read letters from a chart to assess how clearly you can see at different distances.

The doctor may also perform a refraction test to determine the exact lens power required for your eyes. In addition, a slit-lamp examination is used to examine the front structures of the eye, including the cornea, lens, and iris. To check for conditions like glaucoma, an eye pressure test (tonometry) may be conducted.

In some cases, the retina is examined using specialized imaging to detect issues such as diabetic retinopathy or macular degeneration. Regular eye check-ups not only ensure clear vision but also help identify serious eye diseases before symptoms appear.
