Sudden flashes of light in the eyes? Could be due to Ocular Migraine

Are you having sudden flashes of light in your eyes? Well, you should know that it could be due to ocular migraine. If you have an ocular migraine, you may get vision loss or blindness in one eye for a short time i.e., less than an hour. The ocular migraine is linked to spasms in blood vessels in the retina and changes that spread across the nerve cells in the retina. Keep reading to know more about ocular migraine, its symptoms, causes, preventive tips and treatment.

Ocular migraine symptoms

The most common ocular migraine symptoms are listed below.


  • Vision problems that affect just one eye


The vision problems include migraine with an aura or a change in vision. It might happen for only a few minutes or up to 30 minutes. It can be tough to tell whether you are having symptoms in only one eye. That is because the flashing lights or blindness might be on one side of your vision but essentially involve both eyes. If you are still not sure, cover one eye and then the other. If the visual disturbance is occurring in just one eye, it is likely that it is an ocular migraine.


  • A headache that lasts from 4 to 72 hours


The headache tends to affect one side of your head, feel moderate or very painful, pounding or pulsate, and feel worse when you move around.

Other migraine symptoms include nausea, vomiting, and being sensitive to light or sound.

Ocular migraine causes

Listed below are the common triggers.


  • Heredity: There is a hereditary link to an ocular migraine. A family history of migraine or ocular migraine can increase your chances of having them.
  • Hormone levels: Migraines have been linked to the hormone oestrogen. Oestrogen controls chemicals in your brain that affect the sensation of pain. In women, hormones fluctuate due to the menstrual cycle, pregnancy, and menopause. Hormone levels are also affected by oral contraceptives. 


The most common ocular migraine triggers that can cause you to have a migraine attack are certain foods, such as aged cheeses, caffeinated drinks, red wine, smoked meats, and chocolate. Food additives, such as monosodium glutamate (MSG), and artificial sweeteners also can trigger migraines in some. Other possible migraine causes include cigarette smoke, perfumes and other strong odours, glaring or flickering lights, lack of sleep and emotional stress.

Preventive tips

If your ocular migraines appear to be stress-related, you might be able to reduce the frequency of your migraine attacks with the mentioned below preventive tips.

  • Eating healthful meals on a regular basis
  • Avoiding common migraine triggers
  • Getting plenty of sleep
  • Trying stress-busters such as yoga and massage

Ocular migraine treatment

According to the homeopathic system of medicine, migraine is a chronic disease occurring periodically. You might experience it as an acute problem. But because it is periodic and recurrent, it needs continuous homeopathic migraine treatment during the migraine attack and homeopathic medicines need to be taken even when there is no migraine attack. This is to reduce the frequency and intensity of subsequent migraine attacks and eventually stop them.

In all types of acute and chronic illnesses, homeopathy applies the concept of individualisation. This means that even if two people are suffering from the same type of migraine, a homeopath will study your whole case history i.e., your exact nature of symptoms. And then suggest a remedy suitable for each of them to determine deep-rooted and permanent cures.


Never take any chances. It’s a good idea to book an appointment with your homeopath to find out if you have an ocular migraine. The expert homeopaths can rule out other conditions that can cause similar symptoms. Be ready to describe what you went through as completely as you can to help them figure out what’s really going on.
