The cornea permits light to be transmitted into the eye, however some of the light is reflected off of the cornea. This is why we see reflections in a persons eye. This reflective quality of the cornea allows Optometrists use the following process to measure the curvature of the cornea for contact lens fitting. The instrument used is called a keratometer, or curve measurer. The optometrist holds a small object a certain distance from the persons cornea. For this example we will say that the object is 1.5 cm tall and it is held 2.5 cm from the person's cornea. This reflected image is then measured to be, in this case, 0.18 cm tall.
