Can poor vision cause headaches?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Yes, poor vision can cause headaches. When your eyes strain to focus—due to uncorrected refractive errors, presbyopia, or conditions like astigmatism—the surrounding muscles overwork, triggering tension-type headaches, brow pain, or discomfort behind the eyes. Symptoms often worsen after reading, screen use, or driving.

Because headaches can stem from many causes beyond vision—including migraines, sinus issues, or blood pressure changes—it's worth pinpointing the likely source before scheduling appointments or treatments. A free, instant, online symptom check can help you quickly narrow down possible causes based on your specific symptoms and guide your next steps, whether that's seeing an optometrist, a primary care doctor, or a neurologist. It takes just a few minutes and could save you time, worry, and unnecessary visits.

Explanation

When your vision isn't clear, your eyes have to try extra hard to focus on things. This extra work is called eye strain, and it can make your head hurt. Imagine trying to read a book with glasses that aren't the right size—it can make your eyes tired and give you a headache.

Studies have found that when your eyes are overworked because of poor vision, it can lead to headaches. The extra effort your eyes use to see things clearly sends signals to your brain that it has to work too, and sometimes that extra work makes a headache worse.

For example, if you are nearsighted or farsighted and need glasses but aren't wearing them, your eyes may be strained all through the day. If headaches happen often, you can start by taking a free symptom checker test to better understand what might be causing your discomfort, then visit an eye doctor who can check your eyes, see if you need glasses, and help reduce the strain that might be causing your headaches.
