Symptoms of orthostatic hypotension. When the person stands up they may feel lightheaded, dizzy, or what is called a “head rush”. They may feel unsteady and some people can fall. Their vision may change and become blurred or there may be spots, color loss, tunnel vision, or the vision can go completely black.
Orthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when standing after sitting or lying down. Orthostatic hypotension can cause dizziness or lightheadedness and possibly fainting. Orthostatic hypotension can be mild.
When a blood vessel in your retina tightens, it causes a vasospasm. This cuts down on blood flow, which can bring on temporary vision loss in one eye. Various conditions can lead to a vasospasm. These include a retinal migraine, atherosclerosis, and high blood pressure.
Blurred vision often occurs with the dizziness of a vertigo spell. Some common causes of vertigo include dehydration, migraine headaches and sudden head movement.
The most common cause of temporary vision loss is reduced blood flow to your eye. You have a large blood vessel on each side of your neck that brings blood from your heart to your eyes and brain. Fatty deposits called plaque may build up in blood vessels and make them more narrow.
Migraines are the most common causes of temporary vision loss. Migraines may cause blind spots or you may feel like you are seeing flashing lights. Migraines cause Sudden Blindness in both eyes. Giant cell arteritis is another cause of temporary blindness in one eye.
If you are dizzy right now and have any of the following neurological symptoms along with your dizziness or vertigo, call 911 immediately: New confusion or trouble speaking or understanding speech. New slurred speech or hoarseness of voice. New numbness or weakness of the face, arm, or leg.
Finally, severe anxiety can make you feel dizzy, which may make you feel like your vision has become blurred. In the long term, when extreme stress and anxiety happens frequently, your body's heightened cortisol levels can cause glaucoma and optic neuropathy, which can lead to blindness.
Dizziness Can Be a Symptom of an Anxiety Disorder
Your fight or flight instinct kicks in – your fight or flight instinct is often triggered when you feel anxious, as your body prepares for the dangers that you believe are ahead of you. This can lead to a rush of adrenaline, leaving you feeling dizzy and/or lightheaded.
Common causes of sudden vision loss include eye trauma, blockage of blood flow to or from the retina (retinal artery occlusion or retinal vein occlusion), and pulling of the retina away from its usual position at the back of the eye (retinal detachment).
Black spots in your vision are commonly caused by eye floaters. These small spots may be the result of aging, a retinal tear, inflammation or other eye conditions. Age-related macular degeneration (AMD) and other conditions may cause one larger dark or black spot in the center of your vision.

Medically reviewed by Marilyn Folk, BScN. Feel like passing out, including feeling faint or that you might suddenly blackout is a common symptom of anxiety disorder, including generalized anxiety disorder, social anxiety disorder, panic disorder, and others.
“Red flag” symptoms should alert you to a non-vestibular cause: persistent, worsening vertigo or dysequilibrium; atypical “non-peripheral” vertigo, such as vertical movement; severe headache, especially early in the morning; diplopia; cranial nerve palsies; dysarthria, ataxia, or other cerebellar signs; and ...
Generally, see your doctor if you experience any recurrent, sudden, severe, or prolonged and unexplained dizziness or vertigo. Get emergency medical care if you experience new, severe dizziness or vertigo along with any of the following: Sudden, severe headache. Chest pain.
If you have been experiencing vertigo for more than a day or two, it's so severe that you can't stand or walk, or you are vomiting frequently and can't keep food down, you should make an appointment with a neurologist.
Humans are blind for about 40 minutes per day because of Saccadic masking—the body's way of reducing motion blur as objects and eyes move. An eye care provider conducts a thorough eye exam to ensure that these components are functioning well together.
The sudden appearance of spots within your field of vision could also be a symptom of a more serious condition. Sudden blindness may only last a short time such as a few seconds or hours; however, it could potentially be permanent, especially if not treated quickly.
It usually affects part of the vision in that eye – for example the upper or lower part. In some cases, there's only a temporary blockage and vision returns quickly – this is often described as a 'mini-stroke'. People who develop sudden loss of vision should see an expert urgently.
Different conditions, including keratitis, trauma, hyphema, uveitis, acute glaucoma, optic neuritis, papilledema and retinal detachment, can cause sudden loss of vision.
Common symptoms of vision loss include blurred vision, the presence of spots in central vision, and the loss of peripheral vision. There are a number of possible causes of vision loss, including AMD, cataracts, DR, and glaucoma. If a person experiences signs of vision loss, they should contact an eye doctor right away.
The vitreous gel that is in front of the retina can move around, sometimes pulling on the retina itself. As a result , the retina sends light signals to the brain, causing sparkles, stars, or flashes of light to appear in the field of vision. Movement or changes in the vitreous gel become more common as people age.
