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!

This was my first time going to Levin Eye Care Center and I absolutely enjoyed the experience. The staff was very kind and helpful. The exam was pretty straight forward and easy to do. And picking out the perfect pair of glasses was a breeze, and I imagined it would be the most stressful part. The staff was there to answer any questions I had and gave me clear explanation of what I needed to get done. This was definitely the best experience I’ve had. Thank you!

I have been going to Levin Eye Care for 20 years. I have always lived around the Region and never thought about going somewhere else. Dr. Levin and his staff are very professional and attentive but most of all he is personable and spends time with you and talks to you. It’s not a hurry up and get as many people though the door as possible. Not to mention the have the greatest newest styles.
