Week13 Draft1

In an optometrist's exam room, one might find several pieces of equipment, all used to observe different parts of the eye. Commonly found in the examination room, is the phoropter, which is used to measure refractive error of the eye and helps to determine a patient's glasses and contacts perscription. Another common piece of equipment is a slit lamp, which is a microscope that allows light to enter the eye and the optometrist to view internal structures of the eye including the iris, lens and cornea. The tonometer is another tool that allows the optometrist to measure the pressure of the eye, used to detect glaucoma. It provides a more accurate measure of eye pressure, and is an alternative to the air-puff tonometer.
