Migraines are a common condition affecting millions of people worldwide and are caused by a variety of factors, including hormones, genetics, diet, dehydration, stress, and muscle tension. While the exact causes of migraines are not fully understood, there is a clear connection between headaches, eye strain, and muscle tension. Ocular migraines, a rare type of migraine, can cause temporary vision loss in one eye, with symptoms such as blind spots, shimmering lights, and partial or total blindness. It is important to note that ocular migraines are distinct from mini-strokes, although both can cause similar vision problems. While ocular migraines are not caused by eye muscle failure, they can result in visual disturbances due to reduced blood flow or spasms in the blood vessels of the retina or behind the eye.

What You'll Learn
Ocular migraines and their symptoms
Ocular migraines, also known as retinal migraines, are a rare type of migraine that causes visual symptoms in one eye. The visual disturbances are temporary and include blind spots, shimmering or flickering lights, zig-zagging patterns, and floating lines. These symptoms usually last between 5 to 60 minutes, with the average being 10 to 20 minutes. During an ocular migraine, you may also experience a migraine headache, which can occur before, during, or within an hour after the attack. The pain is typically described as moderate to severe and pounding, throbbing, pulsing, or dull. It is usually localized behind the affected eye.
Ocular migraines are distinct from migraine auras, which affect both eyes. While the visual symptoms of an ocular migraine usually subside within an hour, the headache can persist for 4 to 72 hours if left untreated. The underlying cause of ocular migraines is not fully understood, but researchers believe it may be related to issues in blood vessels or blood flow to the retina. There is also a genetic component, with 50% of sufferers having a family history of migraine headaches.
It is important to note that ocular migraines can sometimes be mistaken for migraine visual auras, which cause similar symptoms in both eyes. However, with ocular migraines, only one eye is typically affected. If you experience an ocular migraine for the first time, it is recommended to seek medical advice to rule out more serious eye or brain conditions. Additionally, if you have an ocular migraine diagnosis and your symptoms change or worsen, it is crucial to consult a healthcare provider.
While there is no specific test to diagnose ocular migraines, a healthcare provider may use an ophthalmoscope to observe decreased blood flow to the eye during an attack, which can aid in diagnosis. Preventative medications, such as calcium channel blockers, nifedipine, or verapamil, may be prescribed to help manage ocular migraines. Lifestyle changes and trigger avoidance are also recommended to prevent attacks. Some people find relief through cold or hot compresses, scalp massages, or essential oils that promote relaxation.

Migraines and eye strain
Ocular migraines involve temporary attacks of visual disturbances that affect one eye and migraine headaches. The visual symptoms of ocular migraines may include blind spots, shimmering lights, and partial or total blindness. These symptoms usually last 5-60 minutes. While ocular migraines are rare, researchers don't know how rare they are due to a lack of reporting.
Eye strain, or asthenia, occurs when your eyes get tired from intense use. This can happen after prolonged periods of visually-intense activities such as reading, using a computer, driving long distances, or being exposed to bright light. Digital devices are a common cause of digital eye strain in children and adults. Your eyes work harder when viewing a digital device, and screen glare, poor lighting, incomplete blink patterns, and poor posture can contribute to discomfort when using these devices.
Eye strain can lead to tension headaches, which can sometimes trigger migraines, especially if you are already prone to them. When your eyes are overworked, the muscles that control eye movement become fatigued, and this strain can spread to the muscles around your eyes, forehead, and temples. This extra effort can result in headaches as your brain and eye muscles become overtaxed.
To prevent eye strain and the headaches that come with it, you can make a few simple lifestyle adjustments:
- Follow the 20-20-20 rule: Every 20 minutes, take a 20-second break to look at something 20 feet away. This helps relax the eye muscles and reduce strain.
- Ensure proper lighting: Reduce glare and avoid working in dimly lit environments. Position your light source behind you or use a desk lamp to illuminate your work area.
- Adjust screen settings: Increase text size, reduce screen brightness, and use blue light filters to minimize eye strain. Position your screen at eye level, about 20 to 24 inches from your face.
- Wear the right prescription: Ensure your prescription is current if you wear glasses or contact lenses.
- Stay hydrated: Drinking plenty of water can help prevent dry eyes, which can exacerbate eye strain.

Migraines and vision loss
Migraines can cause temporary vision loss, a condition known as an ocular or retinal migraine. It involves attacks of visual disturbances that affect one eye, along with migraine headaches. The visual issues are temporary and usually last 5 to 60 minutes, with the headache lasting up to 72 hours if untreated. The symptoms of an ocular migraine include blind spots, flashing lights, zigzag patterns, blurred vision, and partial or total blindness in one eye. These symptoms are caused by a restriction in blood flow due to the sudden narrowing of blood vessels in the eye.
While ocular migraines are rare, they can increase the risk of permanent vision loss in one eye. It is recommended that individuals experiencing these symptoms consult a healthcare provider to rule out more serious eye or brain conditions. Additionally, if an individual has an ocular migraine diagnosis and their symptoms change or worsen, they should seek medical advice.
The treatment for ocular migraines involves avoiding triggers through lifestyle changes and medication. Individuals can also use cold or hot compresses, scalp massages, and essential oils to help relieve pain and promote relaxation. However, it is important to note that strong smells can trigger migraines in some people.
Ocular migraines are distinct from strokes, but strokes can also cause similar vision problems. Therefore, it is crucial to seek immediate medical attention if sudden changes in vision occur, accompanied by other symptoms such as one-sided weakness, slurred speech, or loss of muscle control on one side of the body.
In summary, migraines can lead to temporary vision loss in the form of ocular or retinal migraines, affecting one eye. While rare, these migraines can increase the risk of permanent vision loss. Individuals experiencing symptoms of ocular migraines should consult healthcare professionals and consider treatment options that involve trigger avoidance, lifestyle changes, and medication.

Migraines and eye muscle tension
Migraines are a common condition, affecting about 18% of women and 6.5% of men. Ocular migraines, on the other hand, are rare, and their exact prevalence is unknown due to underreporting. Ocular migraines are a type of migraine that specifically affects the eyes, causing temporary visual disturbances in one eye, such as blind spots, shimmering lights, and partial or total blindness. These symptoms usually last 5-60 minutes and are followed by a migraine headache. The pain is typically located behind the affected eye.
While ocular migraines primarily affect vision, they are not caused by eye problems. Instead, they are related to the way the brain processes visual information. During an ocular migraine, the blood vessels in the retina spasm, reducing blood flow to the optic nerves. This disruption in blood flow results in the visual symptoms characteristic of ocular migraines. Importantly, ocular migraines are distinct from strokes, although both conditions can lead to vision problems.
Eye strain, or eye fatigue, is a separate condition that can be a trigger for migraines. It occurs when individuals over-focus on an object, leading to excessive muscle contractions in the eyes and forehead. This can be exacerbated by uncorrected refractive errors, such as astigmatism or myopia, which cause individuals to squint or adjust their posture to see clearly. However, it is important to note that most people with migraines do not have an underlying eye condition, and the causes of migraines are diverse, ranging from hormones and genetics to diet, dehydration, and stress.
If you suspect that your migraines are related to eye strain or other eye problems, it is recommended to consult an eye doctor or optometrist. They can evaluate your eyes for any underlying issues, update your prescription if necessary, and provide personalized advice to reduce eye strain based on your lifestyle. Additionally, keeping a migraine diary can help identify potential triggers and work towards managing your migraines effectively.

Migraines and eye pain
Migraines can cause eye pain, and this is a very common symptom. The pain can be felt in, around, or behind one eye, or in both eyes. This pain is caused by the trigeminal nerve, which carries sensory information about pain, touch, and temperature in the head and face to the brain. During a migraine attack, the trigeminal system is affected, and these nerve endings send pain signals through the trigeminal nerve, resulting in eye pain. This process is known as central sensitization.
Ocular migraines, also known as retinal migraines, are a specific type of migraine that causes visual disturbances in one eye, alongside a migraine headache. The visual issues are temporary and can include blind spots, shimmering lights, zigzagging patterns, and floating lines. These issues are caused by a problem with the way the brain processes visual signals from the eyes. The headache pain associated with ocular migraines is usually located behind the affected eye. While ocular migraines are rare, they can lead to a higher risk of permanent vision loss in one eye.
To manage migraine eye pain, there are several treatment options available. Over-the-counter pain relievers, triptans, and gepants can help alleviate the pain. Additionally, neuromodulation devices, such as Cefaly and gammaCore, use magnets or electric currents to affect nerves involved in migraine pain. Lifestyle changes can also help, such as avoiding triggers, getting enough sleep, reducing stress, and wearing FL-41 lenses to block certain light wavelengths and alleviate light sensitivity.
It is important to note that if you experience an ocular migraine for the first time, you should consult a healthcare provider to rule out any serious eye or brain conditions. Additionally, if you have an ocular migraine diagnosis and your symptoms change or worsen, it is crucial to seek medical advice.
While migraines can cause eye pain and visual disturbances, it is worth noting that there are other types of headaches that may also contribute to similar symptoms, such as cluster headaches and sinus headaches. Therefore, it is always advisable to consult a medical professional for an accurate diagnosis and tailored treatment plan.
