Maybe you’ve been squinting to see road signs recently, or perhaps the words on the computer screen have been blurring together. At Maple Ridge Eye Care, our team knows that these signs can indicate your prescription might be changing. This leads many of our patients to ask the same question: How long do my prescription glasses last?
Many glasses prescriptions are valid for 1–2 years, depending on your age, eye health, and local regulations. Regular eye exams help make sure your prescription still meets your visual needs. Over time, your eyes do shift, so a new prescription may be needed, which can be determined during a comprehensive eye exam.
Typical Lifespan of Prescription Lenses
Many standard prescriptions are designed to last between 1 and 2 years. This is because your eyes do naturally shift over time, which can alter how light focuses on the back of your eye. You may need updated lenses to account for any subtle shifts in your sight.
People with certain eye conditions, risk factors, or health concerns may be advised to have annual eye exams to monitor their vision and eye health more closely. Regular appointments with an eye doctor can help detect potential eye health concerns earlier, when management options may be more effective.
Signs to Update Your Prescription
Physical Vision Changes
Your body might tell you when your glasses aren’t providing you with clear vision anymore. These physical signs might indicate that your current lenses no longer match your needs, and it might be time to book an eye exam:
- Squinting to focus on distant objects like street signs
- Noticing headaches or eye strain during visual tasks such as reading, screen use, or driving
- Blurry vision when looking at a screen
These physical symptoms can disrupt your workday and evening relaxation, but if your discomfort is due to an outdated prescription, updating your lenses may improve visual comfort.
Eye Fatigue and Timelines
Your eyes do a lot of work when you stare at screens all day. Focusing up close for hours at a time might mean your eyes don’t have a chance to relax, leading to eye fatigue.
Over time, your eyes do change. If it’s been 2 years since your last eye exam, your prescription may have changed, so it’s a good idea to schedule your next appointment.
Physical Wear and Tear on Glasses
Everyday drops and bumps take a toll on your frames. We’ve all knocked our glasses off the edge of a table or accidentally sat on them while looking for the remote. These small accidents can create lens scratches that scatter light, making it much harder to see clearly in bright environments.
Lens cracks can also alter your clear vision, as a small crack can distort the image right in your line of sight. Frame damage presents another common issue for daily wearers. A bent frame changes how the lenses sit on your face by shifting the centre of the lens away from your pupil, so your vision may look a bit blurry.
Types of Corrective Lenses
Our eye doctors and opticians can help you find the right lenses for your daily activities. You have many options depending on your specific vision needs and daily habits.
Single and Dual Power Lenses
Single-vision lenses have the same corrective power throughout the lens and are commonly prescribed for distance, near, or both. If you need glasses just for reading books or just for driving your car, single-vision lenses might work for you.
Bifocals, on the other hand, combine 2 different powers into a single pair of glasses. The top portion helps you see distant objects clearly when you walk outside, while the bottom section helps you focus on near tasks like reading a menu at a restaurant.
Multi Power Lens Options
Trifocals provide 3 different zones for clear sight. These lenses help you see far away, at arm’s length, and up close. The middle section is often used for intermediate distances, such as viewing a computer screen.
Progressive lenses are similar to trifocals without visible lines on the lens. The corrective power gradually changes from the top to the bottom of the lens. These options offer a smooth transition between different viewing distances. They help you shift your focus naturally from your phone to the television.
