Switching eyeglasses can be a troublesome business. Your optometrist has undoubtedly told you about initial inconveniences, especially if you're switching to bifocal, trifocal, or progressive lenses, but what if these inconveniences seem like they've come to stay? How do you know if you're wearing the wrong type of glasses?
The issue with knowing if you're wearing the wrong type of lenses for your eye sight is that the symptoms aren't necessarily exclusive for wearing wrong prescription glasses. Blurry vision is a common matter if you're wearing glasses with the wrong strength for you. However, it's also a very common issue for when you're adjusting to glasses after a changed prescription or new glasses all together. If your vision is still blurred after two weeks after getting your new glasses, it's likely you've gotten the wrong prescription.
If you are starting to get headaches while wearing your glasses, this could also be an indication of that you're wearing the wrong type of lenses. Since headaches are a common symptom for plenty of things, many not eyesight related at all, it doesn't have to be caused by your glasses. Try to establish when the headaches are at their worst. If you only have headaches while or directly after wearing your glasses, they might be caused by wearing the wrong type of glasses.
Vertigo, or nausea, is a common problem when getting new glasses. It can be caused by the eyes adjusting to the new depth-perception that comes with getting new glasses. If the glasses are wrong for you, however, this should subside rather quickly after you've been using your glasses for a while. If it doesn't, you might want to look into getting a new prescription.
Not dangerous, but unnecessary
If you experience any or some of these issues, it might be worth another visit to your optician. Wearing the wrong kind of glasses isn't going to damage the eyes permanently. It might, however, make your everyday life harder, since your eyes will be unnecessarily strained and make you feel worse than if you had gotten the right type of glasses right away. To avoid having to deal with any of the symptoms that are described above, it's worth taking an extra look at what type of glasses you are wearing. It should also be mentioned that all of these symptoms can be the signs of different problems with your health. If you can rule out the option that you're wearing the wrong type of glasses, make sure to get yourself checked out for any health related reasons.
