Many people rely on prescription glasses to correct their vision and see clearly each day. Although you may rely on your eyeglasses while spending time on the computer or driving at night, there will likely come a time when you have the wrong prescription due to changes in your vision. If you want to tell whether your glasses are the wrong prescription, there are a few common signs to look for.
A common sign that your vision is not corrected to 20/20 with your current eyeglasses is if you notice that you frequently suffer from headaches while wearing the frames. Incorrect prescriptions can lead to eye strain as your eyes work too hard to see correctly. The headache you develop may present itself by pain above the eyebrows and on the front of the head as often as once a week.
Many people don’t realize they still have blurry vision while wearing their glasses due to a prescription that is off by a few degrees. If you feel like your vision isn’t up to par with your current prescription, perform a test by covering up one of your eyes while staring straight ahead. Repeat the test on each eye multiple times to determine if you notice a difference. It’s important to schedule an eye exam with your optometrist to ensure that your prescription is up-to-date and correct. A routine eye exam should be scheduled each year.
It’s important to remember that you can also experience blurriness in the first two weeks of a new prescription as your eyes adjust. Blurriness that lasts longer than two weeks is a sign that your prescription is incorrect and you need to visit your eye doctor again for a reevaluation.
Nausea or Vertigo
Many people suffer from nausea or vertigo on a frequent basis but don’t always correlate the symptoms or discomfort to their vision. Some people have a prescription that is too high, which can make it easy to feel sick or dizzy, especially while in motion due to issues with depth perception while wearing the glasses. Evaluate how you feel when you’re not wearing your glasses to determine if the prescription may be the cause. Wearing the wrong prescription for too long can lead to eye damage, making it necessary to address the issue immediately.
You may notice that you frequently squint while wearing your glasses as a way to compensate for poor vision. Squinting is the eyes’ natural way of attempting to focus and see clearly, which can lead to eye fatigue and headaches. You may need to update your prescription if you notice yourself squinting while reading or looking at objects in the distance.
An easy way to determine if you have an old prescription is to consider the age of the glasses that you wear each day. If you’ve owned the same pair of glasses for several years, then the prescription is likely outdated because your vision has probably changed over time. An outdated prescription can lead to eye strain and fatigue, which can cause you to feel more tired during the day. You may also notice that your eyes look bloodshot more frequently or you catch yourself constantly rubbing your eyes.
If you experience any of these things, it’s time to visit the eye doctor to get an eye exam for a new prescription!
