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 Patients and Community

Local authorities have ordered a Stay Home order for most businesses in Houston/Harris county. We are currently operating from 10am-12pm for URGENT eye care visits (red eyes, infections, eye injuries, etc...), but no routine/wellness exams are being performed at this time. Furthermore, were are providing "Curbside" pickup of eyeglasses and contact lenses during those hours.

If contact lens wearers currently have less than three (3) months supply remaining, we highly recommend that they call to place an order now. Our doctors will approve up to an additional six (6) months supply. Furthermore, we will waive contact lenses shipping charges and ship directly to a home address at no charge.

With the day to day changes surrounding COVID19, we do not know how much longer our office will be open to the public. Due to this situation, we ask that any remaining glasses or contact lens supplies be picked up as soon as possible.

We thank you for your understanding and loyalty during this difficult time. Wishing you and you health and looking forward to serving you again soon.
