Eye Chart

There are two standard types of eye charts all eye doctors use. These are the Sloan and Snellen models, and the Snellen eye chart model is the most popular version used in offices. The patient will stand at a distance and read down the line until the letters are no longer clear. It helps the eye doctor determine which prescription lenses will benefit that individual.

Phoropter

Are you wondering which of the devices measures refractive error, allowing the doctor to test and find the perfect prescription lenses for the patient? That would be the phoropter. Anybody who’s had an eye exam before has experienced this tool. The doctor will bring it in front of the patient and change lens strengths while inquiring as to which lens allows them to see better. The individual will then reply to let the doctor know which lens was clearer.

Tonometer

The tonometer is the device that aids the doctor in measuring the intraocular pressure (IOP) of the eye. They don’t require a lot of maintenance, just replacing the disposable tip covers after administering a test. There are different forms of tonometry tests, such as indentation tonometry with a Tono-pen or an air puff tonometer. Make sure you regularly schedule tonometry tests. They help identify internal eye pressure and determine if a patient is suffering from vision loss due to damaged optic nerves from glaucoma.

Retinoscope

Sometimes, patients can’t participate in the A and B questions provided by the doctor during the phoropter exam. The ophthalmologist will then use a retinoscope to measure refractive error instead. A beam of light will shine onto the retina to inspect its movement. This movement helps the eye doctor determine the proper prescription for the patient.
