Clear vision plays an important role in your daily life, from reading and working to driving safely. If you live in Smithfield, North Carolina, staying on top of your eye prescription is key to maintaining both visual clarity and eye health. So how long is an optometrist's prescription good for and why does it matter?

How Long Does an Eye Prescription Last?

An optometrist's prescription is typically good for one year. This applies to both glasses and contact lens prescriptions. While some prescriptions may feel “fine” beyond a year, vision changes can occur gradually. Wearing an outdated prescription can lead to eye strain, headaches, blurry vision, and difficulty focusing.

The Importance of Annual Eye Exams in Smithfield, North Carolina

Scheduling annual eye exams in Smithfield, North Carolina is one of the most important steps you can take to protect your long-term vision. Life changes, aging, medical conditions, and even increased screen time can affect your eyesight from year to year.

During a comprehensive eye exam, your optometrist does much more than update your prescription. They evaluate eye coordination, focusing ability, eye pressure, and the overall health of your eyes. Your eye doctor also ensures your eyeglass lenses or contact lenses are properly adjusted to match your visual demands and lifestyle, whether that means extended screen use, outdoor activities, driving needs, or multifocal vision.

For families, annual eye exams are especially important for children and teens, whose visual needs can change quickly. Proper lens or contact adjustments can support classroom learning, digital device use, and overall visual development, helping set the foundation for lifelong eye health.

What Happens If You Use an Expired Prescription?

Using an expired prescription may seem harmless, but it can cause:
 

• Frequent headaches

• Eye fatigue

• Blurred or distorted vision

• Poor night driving vision

• Increased risk of contact lens-related complications

Updating your prescription yearly ensures your vision remains sharp, comfortable, and safe.

An optometrist's prescription is typically valid for one year, and for good reason. Annual eye exams help ensure your vision stays clear while safeguarding your eye health. Even if your eyesight feels unchanged, routine exams play a critical role in early detection and prevention of vision problems.
