Key takeaways

A headache is a symptom with a wide variety of potential causes
Uncorrected vision problems are common sources of headaches
Eye strain from lots of screen time can cause a headache
If you get headaches regularly, see a doctor. If they suspect that the issue is eye-related, they'll likely refer you to an eye doctor.

Headaches come in all shapes and sizes

“Headache” is a broad term that can cover a lot of different experiences. They can be:

Short and mild, or long and disabling

On their own or with other symptoms

A result of one issue, or a mix of several issues happening at once

And may be caused by:

Tightness of the muscles in your head and neck
Changes in the nerves or blood vessels in your head
Chemical activity in your brain

This is why, if you see a doctor about your headache, they may ask a lot of questions about things like your daily activities, sleep patterns, stress levels, vision, the type and location of the pain, how long it lasts, if anything makes it better or worse, and so on. The good news is that many vision-related headaches improve once vision is checked and properly corrected. For some people, even a small change in their glasses or contact lens prescription can make a big difference in how often they experience headaches. This is one of many reasons why routine eye exams matter as part of your overall health.

Is blurry vision causing your headache?

Put simply, your brain really dislikes blurry vision. When your vision is blurry, your brain will try to figure out a way to make it clear— through things like squinting or trying to coordinate eye movements. Over time, this strain can lead to a headache. Here are some of the other more common sources of headache related to vision:

Under- or overcorrected refractive error

If you need vision correction but don’t have any, or if the prescription of your glasses or contact lenses doesn’t match what your eyes truly need, your eyes will strain in an attempt to see clearly. This strain is a common reason you might get headaches after reading, looking at a screen, or focusing on things close to your face. For example, if you have under-corrected farsightedness (hyperopia), your eyes may try to focus through your prescription to make the images sharp. This extra effort can create a 'pulling" sensation that may trigger headaches.

Astigmatism and undercorrected astigmatism

Astigmatism makes vision look distorted at all distances, and often “streaky,” especially at night. This distortion is caused by the cornea on the front of the eye not being perfectly round. Trying to see through this distorted or streaky vision for long periods of time can cause headaches (which some people call “astigmatism headaches”) especially after long periods of close work or driving at night. Glasses or contact lenses that include a cylinder correction (often labeled “CYL” on a prescription) balance out that distortion so you can see more normally. If you think astigmatism might be affecting your headaches, get in touch with an eye doctor to schedule a comprehensive eye exam.

Binocular vision issues

Binocular vision basically means that your brain takes what you see in each eye and combines it to produce a single image. To do this, a lot of coordination has to take place between your brain and body, and if there is any weakness or imbalance of the eye muscles, or a problem with the signal to the muscles through the nerves, the body will struggle to produce a single clear image. This struggle can cause headaches. Some people have binocular vision problems that aren’t obvious at first but show up after long periods of concentration. Treatment can include special glasses or vision therapy, depending on the specific issue. If you notice double vision, headaches after focusing on things near your face like your phone, or eyes that feel tired or sore after reading, a binocular vision assessment might be very helpful.

Eye strain and headaches

Even if your vision is perfect (with or without vision correction) you can still overwork your eyes, which can lead to a headache. Digital eye strain—also called Computer Vision Syndrome—has become much more prevalent as screens increasingly dominate our daily lives. In addition to headache, spending a long time looking at screens (or focusing on anything up close) can make your eyes feel tired, dry, and sensitive to light. An eye exam can help determine whether the strain comes from refractive error, eye alignment, or simply from spending long hours on devices.

Ways to help prevent headaches from vision problems

Get your vision checked regularly

Routine eye exams help catch refractive errors like astigmatism that might contribute to headaches.

Do healthy things for your eyes

Keep your eyes comfortable when looking at things up close by:

Using an up-to-date prescription

Taking breaks frequently

Using proper lighting

Potentially trying computer lenses or progressive lenses designed for digital use

Be mindful of digital device use

This can include an ergonomic setup, appropriate screen brightness, and following the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds).

Getting headaches? Time to see a doctor

If you’re experiencing headaches that are frequent, concerning, and/or seem related to your vision, it’s a good idea to see a doctor. If the issue is suspected to be vision-related, your eye doctor can perform a comprehensive eye exam to check for refractive errors, binocular vision issues, dry eye, or other conditions that could be contributing to headaches. If headaches are frequent, severe, or accompanied by other neurological signs, a physician who specializes in headaches can assess migraine, ocular migraine, and other possible triggers.

FAQs

Frequently asked questions

Does astigmatism cause headaches?

Uncorrected or under-corrected astigmatism can contribute to headaches, especially spending a long time focusing on things that are close to your face. Correcting astigmatism with glasses, contact lenses, or possibly surgery can relieve the strain that leads to headaches.

Can astigmatism headache be helped with glasses?

Yes. Glasses made specifically for those with astigmatism can help reduce the extra focusing effort that your eyes would need without glasses. This often lowers or eliminates headaches caused by astigmatism.

Can not wearing glasses cause headaches?

For people who need glasses, not wearing them can cause eye strain that leads to headaches, especially after long reading, screen time, or anything else where you have to focus on things near your face. If you wear glasses, using them as prescribed helps prevent headaches from vision strain.

Does astigmatism cause headaches with glasses?

Headaches can persist if the prescription is off, but a correct astigmatism prescription typically reduces both distorted vision and headaches. An eye doctor can fine-tune the optics to help minimize strain.

How do I know if my headaches are eye-related?

Eye-related headaches often happen after long periods of screen time or trying to focus on things near your face. They may be accompanied by tired or dry eyes, blurred vision, or double vision. If you are experiencing headaches you should go see a doctor, and if they are eye-related your doctor will likely refer you to an eye care professional for a specialized eye exam.

When should I seek urgent care for vision-related headaches?

Seek urgent care if you have sudden vision loss, sudden severe eye pain, a red, painful eye with fever, or new neurological symptoms such as weakness, speech difficulties, or confusion. These signs may indicate conditions that require immediate treatment.

How can I prevent vision-related headaches day to day?

Get a current eye exam, correct vision with the right glasses or contacts, take breaks from screens using the 20-20-20 rule, stay hydrated, and ensure good lighting and posture during near work.
