What Are Eye Flashes?
Flashes of light in the corner of the eye, also known as photopsia, appear as brief flickers, streaks, or sparkles of light. They can occur in one or both eyes and are often most noticeable in dark environments or when moving the eyes quickly.
Common Causes of Eye Flashes
- Vitreous Detachment – The jelly-like substance in the eye (vitreous) shrinks with age, pulling on the retina and causing flashes.
- Retinal Tears or Detachment – A serious condition where the retina pulls away from the back of the eye, often accompanied by sudden flashes and floaters.
- Migraine Auras – Some migraines cause visual disturbances, including flashes of light, zigzag patterns, or blind spots.
- Eye Trauma – A direct hit or pressure on the eye can stimulate the retina and create flashes.
- Other Neurological Causes – Conditions like optic nerve disorders or strokes can sometimes trigger flashes of light.
When to Seek Medical Attention
While occasional flashes are common with aging, they can signal an emergency if they come with:
- A sudden increase in flashes
- A shower of floaters (tiny specks in vision)
- A dark shadow or curtain over part of your vision
- Blurred or distorted vision
These symptoms could indicate retinal detachment, which requires urgent medical treatment to prevent vision loss.
How Are Eye Flashes Treated?
- Observation – If caused by normal aging, no treatment may be needed.
- Medical Intervention – Retinal tears or detachment may require laser treatment or surgery.
- Migraine Management – Lifestyle changes and medication can help prevent migraine-related flashes.
Final Thoughts
Flashes of light in the eye can be harmless but may also indicate a serious condition. If they occur suddenly or worsen, consulting an eye specialist promptly is essential to protect vision.
