Spotting the Signs: Is Your Glasses Prescription Off?

If you wear glasses on a daily basis, you might feel like they have become a part of your identity. Your glasses are something that you wear every day, and they are supposed to enhance your vision, not make it worse. However, what if your glasses are making your eyesight worse?

In this article, we will explore some signs that may indicate that your glasses prescription is off. We will also discuss what to do if you suspect that your glasses are not helping you see better.

The Importance of the Correct Glasses Prescription

Before we dive into the signs of an incorrect prescription, let us first understand why it is essential to have the accurate prescription of glasses.

When a prescription is written for glasses, it takes into account the shape of your eye, the curvature of your cornea, and other factors that affect your vision. If your lenses do not precisely match your prescription, you may experience headaches, eyestrain, and blurry vision.

Signs Your Glasses Prescription Is Wrong

The Blurred Vision

The most obvious sign of an incorrect prescription is blurry vision. If you notice that objects in the distance or close up appear blurry while you have your glasses on, it is a clear sign that your prescription is not right.

Blurred vision can occur when the lenses of your glasses are not thick enough, or they are too thick, or they are not aligned correctly.

The Eye Strain

Have you ever felt your eyes twitching or getting sore after a long day of wearing your glasses? Eye strain is a common indicator of an incorrect prescription.

The strain occurs when your eyes are forced to work harder than they should to focus because the glasses are not correcting your vision accurately.


Headaches are another common sign that your glasses prescription is not right. It can also be caused by your eyes working too hard to see appropriately.

Headaches can be especially severe if you are wearing the wrong prescription glasses for an extended period.


Have you ever felt like the world is spinning when wearing your glasses? Dizziness could be a sign that your prescription is off.

The reason behind this is that your glasses require your eyes to move differently than usual. When your body tries to adjust to these changes, it can cause a feeling of vertigo or dizziness.

What Should You Do If You Suspect Your Prescription Is Off?

If you suspect that your glasses prescription is not right, you should contact your eye care professional immediately. They will be able to assess your vision and determine if your prescription needs to be updated.

You will likely need to schedule an appointment to have your eyes examined. During this appointment, your eye care professional will examine your eyes and determine the most appropriate corrective action.

How to Get the Right Prescription

To get an accurate prescription, there are a few things you can do:

1. Schedule an Eye Exam

The first step to getting the right glasses prescription is to schedule an eye exam with your eye doctor. They will perform a comprehensive eye exam that includes tests to evaluate your vision, eye health, and other factors that contribute to your eyesight.

2. Be Honest About Your Symptoms

During your eye exam, make sure to be honest about any symptoms you are experiencing. This includes headaches, eye strain, blurry vision, and any other vision changes. Being honest helps your eye doctor determine the ideal prescription to correct your vision.

3. Don’t Use Old Prescriptions

Opt for an eye exam every year, or anytime you notice changes in your vision. Using old prescriptions can lead to more significant problems and make your vision worse.


Proper glasses prescription is essential to your vision and quality of life. If you notice any of the signs mentioned above, it is essential to get in touch with your eye care professional and schedule an appointment right away. Early detection and treatment can prevent vision problems from getting worse.
