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!

Amazing office, from staff to the doctor all were exactly what I wanted And needed. My kids thought they were great as well which is important to me. They fit me in for an appointment last minute and stayed late when it ran over. They helped me figure out a way to pay my bill that I could afford. Every step they were there for me, friendly and smiling. I'd recommend this office without reservation to anyone seeking quality eye care! Thank you all for being so wonderful, I truly appreciate it.

I went to Levin Eye Care Center because of the wonderful reviews I saw online. After discussing improving my acuity and reading skills. They recommended the vision therapy program. Even in my mid-twenties, I decided to go through with it and start the process. The sessions were well worth it and it's an easy one on one setting. I highly recommend to take the 1st step and go see for yourself. The results I have experienced so far is amazing. Thank you once again!!!

I have been going to Levin Eye Care Center for 33 years. My wife has been going longer. Dr. Levin and his staff are very knowledgeable and helpful explaining eye health options. Our entire family are patients at Levin Eye Care Center.
