Is A Poor Fit Affecting Your Glasses Prescription?

Posted on: 29 May 2017


It's quite common for patients to have some initial difficulty adjusting to a new glasses prescription. After months or even years of having your brain grow accustomed to a certain level of vision correction, switching to a new level can induce dizziness or blurred vision, or just cause everything to look odd. However, these problems should wear off fairly quickly, as the brain is very adept at adjusting. If you're still experiencing problems with your glasses a few days into wearing them, it could be a matter of something as simple as a poor adjustment. Read on to learn why this problem is so common with glasses bought online and what you can do to fix it.

Lenses Are Manufactured Precisely

Whether you buy your glasses in-person from an optometrist or online, the lenses in your glasses are designed precisely for you. This not only includes a level of correction that will allow you to see clearly, but something called pupillary distance. Pupillary distance is a measurement of space between the pupils of your eyes, which is where light is allowed in to create an image on your retina. When lenses don't have the correct pupillary distance measurement, it can affect your vision.

However, that's not the only time you can have problems. If your pupillary distance was measured correctly, you can still have problems if your glasses aren't sitting correctly on your face. This is particularly a problem with glasses ordered online, since they're shipped to you unadjusted to your face. While the lenses are made for your eyes, that doesn't mean that the frames are.

Getting Your Glasses Adjusted

You shouldn't try to adjust your glasses yourself. While you can make them sit more snugly on your face, attempting to adjust them yourself could make them crooked. Even setting them off by a millimeter could potentially alter your vision, making it difficult to see through a lens that has the correct prescription.

Instead, visit a licensed optometrist to have your glasses professionally adjusted. Optometrists are trained in determining where a lens should sit over the eye in order for you to see clearly. They can also test your vision before and after the glasses are adjusted to ensure that your vision has been corrected properly.

Buy From An Optometrist

In order to avoid this problem in the future, consider buying your glasses from an optometrist, not an online store. While online stores are fairly popular these days, they can't offer you the hands-on expertise that an optometrist can. Problems like ill-adjusted glasses are quite common with pairs of glasses bought online, and if you end up having to visit an optometrist to have them adjusted anyway, why not get the fully tailored experience of buying them from an optometrist to begin with?

Glasses shouldn't give you a headache or cause problems over a long period of time. If you're struggling to adjust to your new glasses, visit an optometrist to ensure that your prescription is correct and that your frames are fitted correctly to your face.
