What might be happening

Based on the information you've provided, you experienced a sudden, temporary change in your vision where everything appeared grey. This could potentially be due to:

  • Transient Ischemic Attack (TIA): Sometimes referred to as a "mini-stroke," a TIA can cause temporary vision loss like you've described. It happens when part of the brain experiences a temporary lack of blood flow. This can cause stroke-like symptoms that resolve within 24 hours.

    • Diagnostic tests for TIA usually include a physical examination, blood tests, a CT or MRI scan, and possibly a carotid ultrasound to view the inside of your arteries.
    • Treatment usually involves medications to prevent a stroke, since having a TIA puts you at greater risk of having a full stroke.

  • Low Blood Sugar: If you were feeling hungry around the time this happened, it's possible that your blood sugar levels were low. This can cause a variety of symptoms, including blurry vision.

    • Treatment involves eating or drinking something to raise your blood sugar levels. If you experience low blood sugar frequently, you should see a doctor.

  • Migraine: Some people may experience an aura (a temporary visual or sensory disturbance) before or during migraines. It usually lasts less than an hour.

    • Treatment typically involves medications to relieve the symptoms of migraines.

What you can do

Given the potential seriousness of these conditions, you should seek immediate medical attention. In the meantime, try to take note of any other symptoms you experience. If you were feeling hungry, make sure to eat regular meals to avoid low blood sugar.

What you should look out for

Seek immediate medical attention if you experience any of the following:

  • Sudden severe headache
  • Trouble speaking or understanding speech
  • Sudden numbness or weakness in your face, arm, or leg, especially on one side of your body
  • Sudden trouble seeing in one or both eyes
  • Sudden dizziness or loss of balance

Please remember that while I strive to provide accurate information, I'm not a doctor and this advice should not replace a consultation with a healthcare professional.

People Also Ask

What is a Transient Ischemic Attack (TIA) and how is it related to temporary vision loss?

A Transient Ischemic Attack (TIA) is often called a 'mini-stroke' and occurs when there is a temporary reduction in blood flow to the brain. This can cause symptoms similar to a stroke, such as temporary vision loss, which usually resolves within 24 hours. It's important to seek medical attention as it increases the risk of a full stroke.

Can low blood sugar cause temporary vision changes, and what should I do if this happens?

Yes, low blood sugar can cause temporary vision changes, including blurriness or greyness. If this happens, you should consume something sugary, like juice or candy, to quickly raise your blood sugar levels. If you frequently experience low blood sugar, consult a doctor.

What are the symptoms of a migraine aura and how can it affect vision?

A migraine aura is a sensory disturbance that can occur before or during a migraine. It can affect vision, causing temporary changes like seeing flashes of light, zigzag patterns, or grey areas. These symptoms typically last less than an hour.

What immediate actions should I take if I experience sudden vision loss again?

If you experience sudden vision loss again, seek immediate medical attention, especially if accompanied by other symptoms like severe headache, difficulty speaking, or numbness. These could be signs of a serious condition like a stroke.
