How Long Is an Eye Exam & Prescription Good For?

Your vision and eye health change over time, so prescriptions have an expiration date to make sure you always see clearly and comfortably. Getting an updated prescription is as simple as visiting your eye doctor for a comprehensive eye exam.

This helps the whole family stay on track with their eye health, which is especially important for pediatric eye exams and keeps your family’s vision correction accurate. Most glasses prescriptions are valid for one to two years, while contact lens prescriptions typically expire after one year. 

These timeframes help make sure your eyes receive the regular attention that they need and deserve.

How Long Your Prescription Lasts

The validity of your eye prescription depends on a few things, like your age, eye health, and the type of lenses you need. Your eye doctor determines the right expiration date based on your specific circumstances.

Prescriptions for Adults

For most adults, a prescription for glasses is good for one to two years. If your vision is stable, your eye doctor may set a two-year expiration. If your vision changes more often or if there are other health factors involved, it will likely be valid for one year.

Prescriptions for Children & Teens

Children’s eyes can change quickly as they grow, so their prescriptions usually last for one year. Regular exams help keep their vision correction accurate during these important developmental years. This supports their learning and activities.

Contact Lens Prescriptions

Contact lens prescriptions have a shorter lifespan. In most states, including California, contact lens prescriptions are valid for at least one year. This shorter period reflects the fact that contacts sit directly on your eyes, so your eye doctor needs to check the health of your corneas regularly to prevent potential issues. 

A dedicated contact lens exam and fitting helps make sure your lenses are comfortable and safe for daily wear.

Why Eye Prescriptions Have an Expiration Date

A prescription expiry date is a safeguard for your health. Regular eye exams do more than just test how well you see. They’re a key part of preventative wellness.

Your Vision Changes Over Time

It’s normal for your vision to change gradually as you age. An up-to-date prescription makes sure your glasses or contacts provide the right correction. 

An old prescription can lead to discomfort or eye strain, and may not help you see your best.

Check Your Overall Eye Health

A comprehensive eye exam is an important part of your health care. As part of the process, your eye doctor checks for conditions that often have no early symptoms. In fact, routine exams can provide a full picture of your eye health and detect over 270 other health conditions. 

These regular check-ups allow for early eye disease diagnosis and management of potential issues.

Signs Your Prescription Is Out of Date

Your body might tell you it’s time for a new prescription before the expiration date arrives. If you notice any of these signs, it may be time to schedule an appointment with your eye doctor.

Pay attention to how your eyes feel day to day. You may experience:

  • Blurred or double vision
  • Frequent headaches
  • Eye strain or fatigue, which can be a sign of digital eye strain
  • Squinting more than usual
  • Trouble with glare or light sensitivity
