Problems with vision in one eye may be caused by an ocular migraine or diabetes any headache with blurred vision may be a symptom of a stroke, however, and the individual should be examined by a medical professional immediately.

Cataracts are the most common cause of blurred vision among the elderly. The eye becomes clouded from a breakdown of the proteins that form the lens. Objects become blurry and a halo may appear around lights. Some people report a decrease in the intensity of colors and difficulty seeing at night as well.

Glaucoma is an eye disease caused by a build-up of pressure within the eye and can cause blurred vision. The pressure damages the ocular nerve, resulting in visual changes.

What Causes Migraine Pain

Research is still ongoing, but migraines are thought to likely be caused by a phenomenon called cortical spreading depression . This is a process that happens in the brain, more specifically the cortex, when these brain cells are over stimulated.

This stimulation affects the production of serotonin and other brain chemicals. Serotonin then stimulates the trigeminovascular system. This system controls the brains blood vessels, causing them to swell.

Swollen blood vessels do two things:

  • Push on neighbouring nerves causing the sensation of pain.
  • Force the blood to travel through much smaller than normal spaces, making the pulsation of the blood more prominent.

With changes like this happening to the vessels inside our heads, it isnt all that surprising that people often describe the pain as throbbing or as a feeling of pressure inside their head.

How To Treat Sudden Blurry Vision In One Eye

While there are many causes behind your vision getting blurry, the first advice we can give you is to not act on it yourself without getting professional counsel. An eye professional has the tools to help you to make sure your vision stays healthy.

Visit Your Eye Doctor

This is the first step to treat any type of blurry vision-related condition. An ophthalmologist can help you diagnose the underlying cause of your problem, take corrective measures to fix it before it becomes a problem, or treat it before it gets worse. Your doctor will run a battery of tests and find the right diagnosis for you and, luckily, youll regain your vision.

There are a few different tests your doctor could use to determine the cause of your blurry vision in one or both eyes. These tests include:

Slit-lamp Examination

A slit lamp is a lamp that shoots a slit-like beam of light into your eye while you stare at an object. While performing the test, the doctor will usually dilate your pupil to diminish photosensitivity.

Refraction Test

In this test, the doctor will measure your need for prescription glasses, and we’ve all had this test one time or another. The doctor will have you read letters from a distance, also called the Snellen test, while switching lenses to see which helps you see the clearest.


This test measures your eye pressure, and its attached to the slit lamp, so both procedures are done simultaneously. Dont worry it doesnt hurt.

  • A blind spot that slowly migrates across your field of vision
  • A migraine lasting between 4 and 42 hours
  • Sensitivity to light or sound
  • Vision loss
  • Nausea and vomiting
  • A headache that feels worse when you move your head

If you have blind spots or other visual symptoms and arent sure whether it’s an ocular migraine or a visual migraine, cover one eye at a time and observe your sense of sight. If the visual disturbance affects one eye only, it is most likely an ocular migraine.

Can Sunglasses Or Tinted Lenses Help With Photophobia And Migraine

Sunglasses are helpful for use in bright sunlight for most people. Sunglass wear indoors is also helpful for some patients while they are experiencing a headache, migraine or intense period of photophobia. However excess use of sunglasses, such as wearing them indoors under normal circumstances can be counterproductive. Excess wear can result in dark adaptation and dependency, this can result in pain being felt at lower levels of light than before.

FL-41 tinted spectacles have been successful in reducing migraine frequency in some studies. The tint is a pinkish-boysenberry colour. They have also been found to reduce feelings of photophobia between migraine attacks, but made no difference during migraine attacks. FL-41 tint filters out blue light, most likely found in fluorescent lights, reducing the flicker that people are often aware of.
