Phoropter

If, during an eye examination, your doctor has discovered a vision problem like nearsightedness, farsightedness or astigmatism, it’s likely that one of the next steps you’ll take will involve a phoropter. A phoropter is special machine used to switch multiple lenses in front of your eyes to correct your vision.
 
Phoropters look imposing—like space-age visors—but are really an ingenious way to quickly determine the exact vision correction needed by your individual eyes.
 
By having you look through the phoropter at a visual reference, image, or the “Big E” chart (the Snellen chart), your eye doctor will help guide you toward lenses that correct your vision impairment by switching lenses within the machine on the fly.

How does a phoropter work?

The process of switching lenses in front of your eyes is less involved than it may look, given the imposing nature of the device. A phoropter is used to manually determine “refraction”—exactly how a lens must be shaped and curved to correct your vision to a normal state, nothing more.
 
Phoropters are subjective however, based on your visual perception and response to your eye doctor’s questions. Is your vision better, or worse? With this lens, or this lens? How about now?
 
There are other procedures and technologies available that automatically measure the refraction needed within your eye and produce a “prescription” measurement without your input. These are called autorefractors and aberrometers.

COVID-19 Update

Your health and well-being is our top priority at Focusing on Eye Care. In following recommendations provided by the CDC, we have implemented protocols at our office in order to continue to protect the health of our patients and our team.

Every patient and their guest will be asked to fill out a COVID-19 questionnaire. Should you or a guest have flu-like symptoms, fever, exposure to a known person with COVID-19 or have tested positive for COVID-19, you will be asked to reschedule your appointment for a later date until you are well or clear of any potential illness for a minimum of 14 days.

We ask that patients please come to their appointment unaccompanied. If you are requiring a guest to accompany you, we are limiting the number of guests in our facilities to 1 per patient, and we ask that you only bring a guest with you if it is absolutely necessary to avoid crowding in the office.

In addition, we are requiring all employees, patients, and their guests to wear face coverings while in our facilities at all times.

Thank you for all your cooperation as we continue to help you with your eye care needs and for helping us reduce the spread of COVID-19.

Stay Well,

Focusing on Eye Care
