Headaches with new glasses are common while your eyes adjust over 1 to 2 weeks. If it persists, the prescription may be wrong.
Why
New lenses change how your eyes focus. Your eyes and brain need time to adjust.
Duration
Usually 1 to 2 weeks.
Causes
- Wrong prescription.
- Poor frame fit.
- Lens alignment problems.
- Progressive lens adaptation.
Tips
Wear them full time and avoid switching with old ones.
See your optometrist
If headaches last beyond 2 weeks.
Emergency
Sudden vision loss or severe headache. Call 911.
Why new glasses cause headaches
New glasses can cause headaches, eye strain or dizziness because the brain and eyes need time to adjust to a new prescription, lens type (progressives, bifocals), prism, frame position or lens curvature. Adaptation often takes a few days to two weeks.
- Progressive lenses can take 1 to 2 weeks to get used to.
- Incorrect pupillary distance or lens centering, or a prescription error, can cause persistent strain.
- Strong changes in astigmatism correction cause distortion that fades with time.
Tips and when to call
Wear the glasses full-time rather than switching back and forth, adjust the frame fit and nose pads, and take screen breaks. If symptoms persist beyond 2 weeks, return to the optometrist for a recheck, since a lens remake may be needed. Seek urgent care for sudden severe headache, vision loss, eye pain with nausea or halos, which can signal acute angle-closure glaucoma.
Why new glasses cause headaches
New lenses change focus, and the brain and eye muscles need time to adjust, often 1 to 2 weeks. Incorrect prescription, wrong pupillary distance or frame fit can cause headaches.
Tips and when to call
Wear them consistently. If headaches or dizziness last more than two weeks, see your eye doctor to check the prescription.
Why new glasses cause headaches
Headaches are common during the first days with a new prescription, as the eyes and brain adapt to different lens power, base curve, prism or frame position. Progressive lenses take one to two weeks to adjust to, since the viewing zones are different. An incorrect prescription, pupillary distance error or lens alignment can also cause strain.
What to do
Wear the glasses full time for 1 to 2 weeks and avoid switching back to the old pair. Check that the frames fit and sit at the right height. If headaches, dizziness or blurred vision persist beyond two weeks, return to the optometrist to check the prescription and lens measurements. Most shops offer a remake or adjustment policy for 30 to 90 days. Take regular breaks from screens and follow the 20-20-20 rule, looking at something 20 feet away for 20 seconds every 20 minutes.
