TL;DR
Headaches can have many triggers, from dehydration to lack of sleep. However, problems with your vision may also play a significant part, especially if they go unnoticed or untreated.
Understanding how your eyes might contribute to headaches is essential if you want to manage the issue more effectively. Find out what causes these headaches, how to spot the signs, and what to do next.
How your eyes and head pain are connected
The eyes and brain work together to process everything you see. When your eyes are under strain or not functioning properly, your brain has to work harder to make sense of the input. This added pressure can sometimes trigger a headache.
This type of headache is often referred to as an eye strain headache or ocular headache. It tends to feel like a dull ache behind the eyes or around the temples. Some people might experience blurred vision, tired eyes, or even sensitivity to light along with the discomfort.
Eye strain is a common cause of headaches
One of the most common links between eye problems and headaches is eye strain. This often happens when you focus on something for too long without a break. Digital screens are a major factor, especially with the average adult spending more than six hours a day looking at devices.
If you stare at your phone, computer, or television for long periods without resting your eyes, your muscles have to work overtime to maintain focus. This can lead to tension around your eyes and forehead, which eventually builds into a headache.
You may also notice watery eyes, dry eyes, or trouble keeping your eyes open when you’re dealing with eye strain.
Vision problems that might trigger headaches
Sometimes, headaches are your body’s way of telling you there’s an underlying vision issue. Conditions such as the following can all lead to headaches if not corrected properly.:
- Short-sightedness (myopia)
- Long-sightedness (hyperopia)
- Astigmatism
For example, if you’re slightly long-sighted and have to strain to read or focus on nearby objects, your eyes will overwork to maintain clarity. That effort can turn into discomfort and eventually a headache.
Astigmatism, a common condition where the eye isn’t perfectly round, causes blurred or distorted vision at all distances. Trying to focus through this distortion can create long-lasting tension headaches.
Even small changes in your vision that go uncorrected may cause issues. Many people do not realise that their prescription has changed until they start experiencing regular headaches or eye discomfort.
How to figure out if your headache is linked to eye problems
Not all headaches are caused by eye problems, so it helps to look at the pattern of your symptoms. Ask yourself:
- Does the pain start after reading, screen use, or focusing for a long time?
- Do you notice blurred or double vision?
- Is the headache located around your eyes or forehead?
- Do your eyes feel dry, tired, or sore?
If you answer yes to one or more of these, it’s worth booking an eye exam. An optician can check for prescription changes and spot any underlying problems you may not be aware of.
Ways to relieve the pressure
If your headaches are caused by eye strain or uncorrected vision issues, the solution can often be simple. Getting the right glasses or contact lenses can make a big difference. So can adjusting your screen habits.
Try following the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This helps your eye muscles relax and reduces the risk of tension building up.
Good lighting is also essential, particularly when reading or working. Poor lighting forces your eyes to work harder, increasing the likelihood of discomfort.
In some cases, using artificial tears can help relieve dry eyes that contribute to irritation and pain. If your job involves a lot of screen work, an anti-glare screen or blue-light filter may also help.
When to speak to a professional
If your headaches continue despite lifestyle changes, or if they get worse over time, it’s best to consult a healthcare professional. A GP can help rule out other causes and may refer you to a specialist if needed.
Your optician may also refer you to an ophthalmologist if they spot anything unusual during your eye exam. Some headaches might not be related to vision at all, so getting a proper diagnosis is important before making assumptions.
