Is It Time to Update Your Glasses or Contact Lens Prescription?

Our eyesight often changes gradually, so it’s not always easy to notice when your prescription needs an update.
Here are a few signs to look out for:
• You find yourself squinting to read or see detail
• Your eyes feel tired or sore after using screens
• Driving at night has become harder or blurrier
• You’re getting more frequent headaches or eye strain
• Things just don’t seem as clear as they used to
If any of these sound familiar, it’s a good idea to book an eye test. Regular eye exams not only keep your vision sharp, they also help pick up early signs of eye conditions before you notice any symptoms.
