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.

We are happy to announce that beginning May 11th, we will resume patient care!  Out of an abundance of caution, and guidance from various health agencies including the CMS, CDC, and CDPH, we will be following various safety protocols to protect the health and safety of our patients and staff.  The following protocols apply whether you are coming in for an eye exam, coming to pick out new glasses, or picking up glasses or contacts. Prior to entry there are 3 important steps:

1.  Bring your own mask: You must bring your own mask or face covering!  It is required to be worn at all times within the office (we are unable to provide masks from the office; if you do not bring a mask, we will have to reschedule your visit for a later date).

2.  Body temperature reading: Staff will be administering thermometer readings, and must be within normal range for entry into the office.

3.  Attest to good health: You must attest to good health, with no symptoms of fever, cough, shortness of breath, chills, sore throat, loss of taste/smell, and have not had contact with another person with COVID19 in the past 14 days.

 In addition, we will include limiting the number of patients in the office.  Therefore, you may be asked to call the office upon arrival, and may need to wait outside or in your car until you are called into the office.  Only patients will be allowed in the office (please have spouses, relatives, and friends wait outside of the office).  Exceptions include minors and dependents...may be accompanied by one adult parent or caretaker.

Sincerely,

The Natomas Optometry Team
