Adults: This is When You Need to Get Glasses

Blog, Eye Exam, Eye Information, Eyeglasses

Did you know approximately 75% of adults require corrective lenses? Whether or not you have a current prescription, the chances that you will need glasses one day are high. Knowing the signs that indicate vision correction may be required can help you maintain control of your eye health and avoiding damaging your eyes further.


So, how do you know when it’s time for glasses? Understanding the symptoms is a great way to learn when corrective lenses are needed. However, the same signs that indicate you need glasses can also be signs that you need to change your prescription.

How do you know when to get glasses (and when to change them)?

Often, you’ll know when you need to get glasses by recognizing symptoms that your vision is deteriorating. These indicators usually arise if it’s been over a year since your last eye exam. Adults should have a comprehensive exam every year, and if you miss it, the optometrist will not be able to tell you if your depth perception has changed or if you’ve developed any new eye conditions.


Here are the symptoms of when to get glasses and when you should consider changing them:

Symptom #1: Frequent Squinting

Frequent squinting can indicate you may need glasses or answer your question of, ‘When do I need to change my glasses?’, especially if you haven’t had your prescription updated in a while. Adults squint to keep light from entering their eyes. Squinting also reduces the size of blurry objects. 


Squinting usually tells you that you need glasses since it can indicate you have trouble identifying objects far away or nearby. Sometimes, frequent squinting can mean you are farsighted or nearsighted. Farsightedness and nearsightedness can develop if you wear outdated corrective lenses since the magnification level may not be right for your needs.


So, if you’re squinting more than usual in your glasses and haven’t had an eye exam in over a year, put getting new glasses on your to-do list. A quick trip to an eye doctor near you is all you need to confirm whether a new prescription will help your eyes.

Symptom #2: Blurry Vision

People with vision issues often complain of blurry vision. If you have blurry vision, you may find that objects look fuzzy, no matter how far away they are. This is one way to know when to get glasses, and it often comes up when you’re reading. 


Blurry vision in your eyes can mean you are farsighted or nearsighted. It can also mean you have astigmatism, a condition caused by a misshaped cornea. Astigmatism prevents light from entering a central part of the retina. Having all light meet in one area of the retina is essential to unclouded vision. 


Fortunately, books, objects, and screens become clearer with corrective lenses. Knowing when to get glasses can clear up your vision right away and help you feel and see like you should. If you’re suddenly getting blurry vision while wearing corrective lenses, it is time to update your prescription. An optometrist can perform some simple and routine tests to see if increasing the magnification on your lenses will help enhance your clarity when looking at objects.

Symptom #3: Keeping One Eye Closed While Watching Your Favorite Shows

Do you find yourself watching TV with one eye closed? You may have a vision problem. If this is you, one eye may be farsighted or have astigmatism. The other eye may compensate, which can cause you to close the opposite eye.


Watching TV with one eye may work, but it can result in problems over time, which can be addressed with corrective lenses. Understanding when to get glasses starts with recognizing that you need both eyes, not one eye.


If you’ve been having trouble seeing out of both eyes while binging your favorite shows, consider stopping by the eye doctor for a new prescription. Many people have difficulty focusing on the screen with both eyes when their vision has changed, and new glasses may be all you need to correct this symptom.

Summary: When do I need to change my glasses?

There is only a 25% chance you will not need glasses one day, so watching out for your eye and vision health is essential. The same symptoms that indicate you need glasses can also be the symptoms that suggest you’re due for new eyewear, making it a necessity to have an annual exam. 


If you’re not sure if you need new glasses, ask yourself:


  • Have I been squinting a lot?
  • Has my vision been blurry?
  • Have I been watching TV with one eye closed?


If you answered “yes” to any of these questions or have any other concerning eye health issues, it is time to set an appointment. The optometrist can assess the kinds of prescription lenses you need to improve your vision.
