You may have had your glasses for years and still think you see perfectly clear with them, but there’s a good chance you may not have noticed that your vision isn’t as great as when you first got your pair of lenses.
So when you start to take notice of the following signs, it’s probably time to schedule an appointment with your optometrist:
Recurring headaches is perhaps the most overlooked factor people notice, but it’s the most telling sign that you need to change your lenses.
This happens because while you’re actually seeing things slightly more blurry than usual over time, your brain compensates for this and tries to correct the problem. The result is that your brain expends energy correcting your vision, and you get headaches.
Another sign that you need to replace your glasses is if you find yourself squinting to focus on objects. This is especially true if you’re nearsighted and need to see distant objects clearly. But what you don’t realize is that this does more damage over time.
In fact, squinting actually forces your eyes to focus, which adds more strain on them, and if you find this more likely to happen when you’re reading or a book or using a computer, then you’re due for a prescription change.
3. Blurred Vision
Having blurred vision is less obvious at first since you don’t notice this right away. However, you will eventually notice a moment when your vision is suddenly blurred even with glasses on.
If this is the case, you will need to see your optometrist to determine whether you need a prescription change or treatment for other conditions that cause significant changes to your vision, such as cataracts.
4. Eye Fatigue
While this can be caused by a lot of other factors (such as a lack of sleep or seasonal allergies), they usually only last a day or two at most. Persistent eye fatigue, meanwhile, is a common symptom caused by having outdated prescription lenses.
IF you’re experiencing eye fatigue more frequently than you used to, having a prescription change may be due in order to relieve some of the strain.
5. Lens Scratching
Wear and tear is also a huge factor for needing a regular prescription upgrade. Even though scratches on your lenses may seem un-obtrusive at first, they could significantly affect your vision and increase the amount of eye strain you experience.
The same can also be said for glasses with special coatings or outdated features, such as those designed for anti-UV or for glare reduction. In fact, if your glasses are longer than two years old, you should have them replaced with a prescription that suits your needs.
