When Should You Recheck Your Prescription? Signs Your Vision May Have Changed

Most people only think about their glasses or contact lens prescription when something feels really wrong. But changes in vision often happen gradually, and when left unchecked, they can affect everything from your comfort and productivity to your long‑term eye health.

So how do you know it’s time to recheck your prescription? Here are the most common signs and the reasons why regular eye exams matter more than you might expect.

You’re Squinting More Than Usual

Squinting is your eyes’ way of trying to sharpen blurry images. If you find yourself narrowing your eyes to see street signs, read a screen, or view distant objects, your prescription may no longer be strong enough.

Why it matters:
Consistent squinting can lead to headaches and eye strain - and often indicates worsening short‑ or long‑sightedness.

Frequent Headaches, Especially After Screen Use

Headaches that develop after long periods of reading, driving, or working on a computer can be an early sign your vision has changed.

Why it matters:
Your eyes may be overworking to compensate for outdated lenses, especially if you have astigmatism or digital eye strain.

Blurry Vision - Near, Far, or Both

If text is starting to look fuzzy or objects far away don’t appear as sharp as they used to, it’s time for a check‑up. This can happen whether your current prescription is too strong or too weak.

Why it matters:
Blurriness can indicate changes in refractive error, dry eyes, or other underlying issues.

Night Driving Has Become Difficult

Struggling with glare from headlights, halos around lights, or trouble seeing road signs at night can all point to vision changes.

Why it matters:
Night vision declines naturally with age, but outdated lenses can make it worse—impacting both safety and confidence behind the wheel.

Your Eyes Feel Fatigued or Dry

Eye fatigue, dryness, or irritation, especially after using digital devices, may be signs your eyes aren’t aligning comfortably with your current prescription.

Why it matters:
Even small changes in prescription or uncorrected astigmatism can make your eyes work much harder than they need to.

You’ve Started Holding Things Closer or Further Away

If you catch yourself moving your phone, book, or menu around to find the “clear spot,” your near‑vision may be changing.

Why it matters:
This is especially common in people over 40 as presbyopia (age‑related difficulty focusing up close) begins to develop.

Your Glasses or Contacts Suddenly Feel “Off”

If your lenses no longer feel right, maybe things look warped, distorted, or you have trouble adjusting after putting them on, your prescription may no longer match your needs.

Why it matters:
Wearing the wrong prescription can cause dizziness, nausea, or balance issues.

How Often Should You Have an Eye Test?

Even if you feel your vision is fine, regular exams are essential. General guidance:

• Adults 18–60: every 2 years (it can be annual in some cases for contact lense checks, etc)

• Adults over 60: every year

• Children: every 1–2 years, depending on age and visual needs

• Anyone with existing eye conditions: as advised by an optometrist

  
  

  
  

Why Regular Eye Tests Are So Important

Vision can change for many reasons, and an eye exam does much more than update your prescription. It can detect:

• Eye diseases like glaucoma and cataracts

• Early signs of diabetes or high blood pressure

• Changes in eye pressure

• Retinal issues

• Dry eye or digital eye strain

Many of these conditions don’t cause noticeable symptoms early on - which makes routine checks essential.

Your eyesight is constantly evolving. If you’ve noticed any of the symptoms above, or it’s simply been a while since your last check‑up, it may be time to book an eye test.
