Blurry Vision Headaches
Pain in any region of the head is called a headache. Nearly everyone has experienced a
headache, some of us have had it several times. If a headache is accompanied by blurred
vision or double vision, then it is called a blurry vision headache.
It is frightening to experience a headache that spreads from your head to your eyes, to blur your
vision – especially when it happens for the first time. It can affect one or both eyes and it can
show other optical symptoms as well. Many possible conditions can cause a headache with
blurred vision, with migraines being the most common cause of all.
Types of Headaches That Can Cause Optical Symptoms
Migraine
Migraine is a common primary headache disorder. The Global Burden of Disease Study 2010,
ranked it as the third most prevalent disorders in the world. It is also ranked as the seventh most
disabling disease in the world and is three times more common in women than in men.
However, in children, migraine is slightly more common in males.
Migraine typically occurs from childhood to middle age. Its frequency decreases during
pregnancy or with advancing age.
About 20% of migraine sufferers have headache attacks with aura. Aura means any
neurological disturbance that appears shortly before or during the migraine headaches. The
neurological symptoms of migraine with aura usually develop over a 5-20 minutes period and
lasts for less than an hour.
Migraines that causes visual symptoms like halos, zigzag lines, blind spots, sparkles or flashing
lights, etc. are defined as ocular migraine or migraine with aura. Neurologists believe that aura
is caused by hyper-excited nerves in the brain which are activated in the visual processing
areas of the brain before the onset of migraine pain. Also, genetics play an important role as
70% of the migraine problems are hereditary.
Symptoms: Migraine symptoms vary widely, however, they can include:
●
●
A blind spot in the field of sight that spreads to cover up to half of the visual field
Often preceded by several hours of depression, irritability, fatigue, and sluggishness

Halos, sparkles or flashing lights, tunnel vision, temporary blindness or temporary
flashes of stars
Slurring of speech
Numbness or tingling on one side of the body
Watery eyes, running nose or congestion
Throbbing or pulsating pain, often beginning around the eye and temple, spreading to
the back of the head
Nausea and vomiting.
Use POUND method to identify migraine pain
P- pulsating pain
O- one-day duration of severe untreated attacks
U- unilateral or one-sided pain
N- nausea and vomiting
D- disabling intensity.
Cluster Headaches
Cluster headaches are uncommon but are very severe and strictly unilateral headaches. They
are five times more common in males than in females. Although they can affect anyone, they
are more common in middle-aged males with a history of smoking.
The term cluster is used because the headaches come in clusters or bouts, occurring one to
eight times a day. Attacks last for weeks or months separated by remission periods usually
lasting months or years.
A cluster headache comes on quickly, sometimes with aura or blurring, and strikes on one side
of the head. The exact cause of cluster headaches is unknown, but patterns suggest an
abnormality in the hypothalamus as being the cause.
Symptoms: A cluster headache starts quickly and usually without any warning signs. Some
common symptoms of cluster headache include:
●
●

●
Excruciating pain on one side of the head
eye on the painful side is watery, red, and with droopy eyelids
forehead or facial sweating on the affected side
Runny nose and congestion on the affected side
Restlessness
Nausea and sensitivity to light.
Eye Strain Headache
Eye strain is a common condition nowadays, all thanks to the digital era of screen addiction.
According to The Vision Council, 80% of American adults spend more than two hours a day with
their eyes fixed on any digital device and about 59% of them report experiencing symptoms of
digital eye strain.
Intense use like prolonged exposure to digital devices or driving long distances disrupts the
eye’s ability to focus and often leads to eye muscle strain.
Symptoms: Strained eyes often results in:
●

Dizziness
Sore neck or shoulders
