Have You Ever Wondered What A Phoropter Does?

Written by Levin Eye Care on . Posted in Eye Health

This is a question we love getting: “What does that big, space helmet-looking thing actually do anyway?”

Most patients have wondered what that large, imposing piece of equipment is that they always see at the optometrist’s office. Well, it’s called a phoropter, or a refractor, and it’s an awesome tool we eye docs love to use! Read on to find out more!

A Brief History Of The Phoropter

The phoropter was invented in the early 1900s. One, called the Ski-optometer, was invented by Nathan Shigon and another, called the Phoro-optometer was developed by Henry DeZeng. Later came Bausch and Lomb’s Greens’ Refractor.

The phoropter was unique from the device that was previously being used, the monocular optometer, because the phoropter was able to measure refractive errors as well as traits of binocular vision (meaning how well the eyes work together), among other things.

In today’s world, as technology gets more and more advanced, usually devices get smaller and more streamlined. You may be surprised to hear that with almost every new model that came out, the phoropter kept getting bigger and bigger! Over time, the phoropter continued to improve until it became what it is today in the 1960s, still as big and bold as ever.

Phoropters Help Us Fine-tune Your Prescription

This may sound familiar… you walk into the optometrist’s office and after some initial tests and pleasantries, you’re asked to sit behind the “space helmet” and look at the eye chart through the phoropter lenses. As we change the lenses with different optical powers, we’ll ask you the question we know you all love to answer, “Which is more clear, one or two?”

Based on your answers, we come up with a prescription that gets you as close to seeing 20/20 as possible. The phoropter is an amazing tool that helps us fine-tune your prescription and make sure you have the clearest, most accurate vision possible!

My early elementary school aged son has gone through 2 sessions of vision therapy and it has greatly helped him. His grades and tests scores are way up and he truly enjoys reading now. Dr. Levin and Ms. Janet the therapist do exceptional work. The progress my son has made is phenomenal. I would recommend this program to anyone with a child struggling in school due to vision issues.

I have be n going to Levin Eye Care Center since high school (before it became Levin) During all these years, the staff has been amazing. I know I am getting a thorough exam that might point to other health issues as I get older. Dr. Levin is great and i highly recommend him and Levin Eye Care!

Before coming to Levin Eye Care Center for vision therapy, I had trouble reading and seeing things clearly whether nearby or in the distance. After working through the vision therapy program, it improved my vision and allowed my eyes to work as a team. I have been coming back for eye exams since then, and always have a positive experience. I’ll be moving to New York for graduate school and studying architecture at Columbia University and I can say without a doubt that the Levin Eye Care Center vision therapy program has helped me get there. I wish I could take the practice and Dr. Levin with me!

When it came to selecting glasses Tianna VERY patient & helpful. She helped me find the perfect fit glasses. They have a large selection of amazing designer glasses & sunglasses!!! Can't thank her enough for helping me!
Dr. Levin always wonderful. Makes sure I am seeing 20/20 every visit. This the 3rd time I have seen Dr. Levin.
He also took extra time making sure my contacts were the perfect fit. I have very sensitive eyes. He ordered a variety of contacts just to make sure I found the ones that fit my eye best.
Highly recommend this wonderful eye care center!!!!!!!!!!!
