We’ve all had to answer the question “Is it Better 1 or Better 2”?
It’s surprising how many patients dread this test! They are uncomfortable having to choose the right answer. We hope to dispel any concerns you might have by giving you some insight into how we determine your glasses prescription. It’s called a refraction.
You look at the eye chart through a device called a phoropter. The phoropter contains a collection of lenses to help determine your best vision. We test each eye individually using a series of dials to switch the lenses to find the best power for you.
Don’t worry that you might give the wrong answer!
The phoropter is just one part of the equation that the doctors at Eye Rx use to determine your eyeglasses prescription.
- Auto-Refractor: We take a measurement of your eye with an auto-refractor. You will sit a machine and look at a picture which will come in an out of focus as the machine measures your eye. This machine gives us a prescription based solely on your eye measurements.
- Your current prescription. We will ask you to read the eye chart using your current glasses or contacts to see if a change is needed.
- Refraction: Then, using the phoropter, we will go through a series of choices asking you which lenses give you clearer vision. It’s ok to ask to see the choices again if you aren’t sure. Sometimes you will notice a dramatic change. Other times you may not notice a difference at all. It’s OK to say that you don’t see a difference!
When you look at the eye chart, we listen to what you say and how you say it! We can tell if the letters are sharp and crisp by how you respond. A patient who reads the answers confidently and quickly is seeing well. On the other hand, a patient who is unsure reads hesitantly and slowly. Listening to your answers gives us additional insight into how clearly you are seeing.
Relax, don’t worry!
Determining your best prescription is a process! We want you to get your best result, and we have many tools to get you there!
P.S. For those patients who think they have the eye chart memorized…let us know! Reading the eye chart is a vision test, NOT a memory test! We can change the eye chart to get a true reading of your vision.
