Only 2% with a unique vision will pass the test.

Corneal Topography
This computerized test maps the curve of your cornea. It can show problems with your eye’s surface, like swelling or scarring, or conditions such as astigmatism or diseases like keratoconus. You might have it before you have surgery, a cornea transplant, or a contact lens fitting.

Fluorescein Angiogram
This lets the doctor see how well blood moves in your retina. It helps diagnose diabetic retinopathy, retina detachment, and macular degeneration. The doctor will inject a special dye, called fluorescein, into a vein in your arm. It travels quickly to blood vessels inside your eye. Once it gets there, the doctor uses a camera with special filters to highlight the dye. They takes pictures of the dye as it goes through the blood vessels in the back of your eye. This helps them spot circulation problems, swelling, leaking, or abnormal blood vessels.

Dilated Pupillary Exam
The doctor uses special drops to expand your eye’s pupil (they’ll call this dilate). That lets them check your retina for signs of disease.

Refraction
This is what the doctor uses to get your eyeglasses prescription. You look at a chart, usually 20 feet away, or in a mirror that makes things look like they’re 20 feet away. You’ll look through a tool called a phoropter. It lets the doctor move lenses of different strengths in front of your eyes. You can tell them if things look clear or blurry. Your answers give them your prescription for your glasses or contact lenses. The test will also help them spot presbyopia, hyperopia, myopia, and astigmatism.

Slit-Lamp Exam
The doctor uses this microscope to shine a beam of light shaped like a small slit on your eye. They may also dilate your pupils during the test. It can help diagnose cataracts, glaucoma, detached retina, macular degeneration, cornea injuries, and dry eye disease.
