The eye doctor may use a microscope called a slit lamp to examine the front of the eye. The microscope focuses a narrow, intense line of light on the eye. The slit lamp provides an enlarged 3D view of the eye and allows the doctor to detect any minor abnormalities. A slit lamp is a microscope with a bright light that is used during an eye exam.
It allows the ophthalmologist to take a closer look at the different structures in the front and inside of the eye. It is a key tool for determining eye health and detecting eye diseases. The slit lamp exam examines structures in the front of the eye. It will then turn on the slit lamp and focus a narrow, high-intensity beam of light toward the eye.
Once you are in the ophthalmologist's exam chair, he or she will place a slit lamp in front of you and ask you to rest your forehead and chin on the supports.
