Getting a new pair of glasses or contact lenses is always an exciting experience.

1. The Typical Adjustment Period

For most individuals, the adjustment period to a new eye prescription spans:

  • Mild Prescription Changes: 1-3 days.
  • Significant Prescription Changes: Up to two weeks.

During this period, you may experience blurriness, slight dizziness, headaches, and a feeling that you’re not seeing as crisply as you should.

2. Factors Influencing the Adjustment Period of a New Script

  • Type of Prescription: Multifocal lenses, like bifocals or progressives, often require a longer adjustment period than single-vision lenses.
  • Significance of Change: A major change in prescription will likely take more time for adaptation than a minor tweak.
  • Personal Factors: Some individuals naturally take longer to adjust due to age, eye health, or adaptability.

3. Tips for a Smoother Transition

  • Consistent Wear: To expedite adjustment, consistently wear your new glasses or contacts during waking hours. Resist the urge to switch back to your old pair.
  • Start Indoors: For significant prescription changes, start by wearing your glasses in a controlled environment, like your home, before venturing out.
  • Avoid Driving: Until you’re comfortable with your new prescription, it might be safer to avoid driving or operating heavy machinery.
  • Eye Exercises: Simple eye exercises, like focusing on close and far objects alternately, can help your eyes adapt faster.
  • Rest and Hydrate: Ensure you’re well-rested and stay hydrated. Fatigue can prolong the adjustment phase.

4. When to Consult Your Optometrist

If after two weeks you’re still experiencing severe discomfort or the symptoms seem to worsen, it’s vital to revisit your optometrist. There might be an error in the prescription or the lens fabrication.


Adjusting to a new eye prescription requires patience. It’s a phase where the brain is adapting to a new way of seeing. Armed with knowledge and a few practical tips, you can make the transition smoother and get back to seeing the world in sharp, vivid detail.
