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.

Dear TSO Patients,

We will continue taking precautions at our office.

-Our staff will be wearing masks. We also ask that any patient coming to our office wear a mask.

-Patients will call our office when they arrive to check in. Patients will be asked to stay in their cars until we are ready to start the exam.

-Patients’ temperature will be taken upon entry, and they will be asked to sanitize their hands.

-To reduce the amount of people in the office, only the patient is allowed into the exam room unless the patient is a minor or need additional assistance.

-Exam rooms, credit card terminals, counter tops, etc. will be wiped down between patients.

-Patients should call when they come for pickup of glasses and contact lens orders, we will deliver to them curbside.

-Frames that have been handled in the optical will be placed into a tray, and sanitized before they are returned to the frame board.

-Our office will continue to do curbside dispensing for eyeglasses and contact lenses.

Thank you for your support.

Drs. Hassett, Noorali, and Your TSO Staff
