Why Do Eyeglass Prescriptions Expire?
Your vision isn’t fixed—it can change due to age, health conditions, or lifestyle habits like extended screen time. Children and teens often need new prescriptions every year because their eyes are still developing. Adults may experience more gradual vision changes, especially after age 40. Certain medical conditions like diabetes or high blood pressure can also impact your eyesight.
Having an up-to-date prescription ensures that your glasses are doing their job—reducing eye strain, preventing headaches, and improving daily comfort.
How Long Does an Eyeglass Prescription Last?
In most cases, an eyeglass prescription is valid for one to two years. The exact duration depends on your age, eye health, and state regulations. Here's a general guideline:
-
Adults (18–60): Usually every two years
-
Children & Teens: Recommended once a year
-
Seniors (60+): Often once a year, due to higher risk of age-related eye conditions
Be sure to check with your eye doctor or local guidelines, as some regions have specific rules about prescription validity.
Signs You May Need New Glasses—Even If Your Prescription Isn’t Expired
Sometimes your eyes change before your prescription officially expires. Look out for these signs:
-
Blurry or double vision
-
Frequent headaches, especially after reading or screen use
-
Eye strain, tired or sore eyes
-
Trouble focusing or needing to squint
If any of these sound familiar, it might be time to schedule an eye exam and update your lenses.
How Often Should You Get an Eye Exam?
Routine eye exams are key to keeping your vision sharp and prescriptions accurate. Here’s what most experts recommend:
| Age Group | Recommended Frequency |
|---|---|
| Children & Teens | Every year |
| Adults (18–60) | Every 2 years |
| Seniors (60+) | Once a year |
Even if you don’t wear glasses, regular eye exams can catch early signs of eye disease or other health issues, such as glaucoma, cataracts, or even diabetes.
Why It’s Worth Keeping Your Prescription Updated
Keeping your eyeglasses up to date is about more than just clear vision. An accurate prescription helps:
-
Reduce headaches and eye fatigue
-
Improve reading and screen comfort
-
Support safe driving and better focus
-
Catch early signs of eye disease or health problems
Taking care of your eyes now can help prevent bigger issues down the road. It’s a small step with long-term benefits.
