Seeing glitter in your vision is a common symptom that can have various causes. It's often described as "floaters" or "sparkles" and can be a harmless phenomenon or a sign of a more serious underlying condition.
Possible Causes:
- Eye Floaters: These are tiny specks or strands that appear to float in your field of vision. They are caused by clumps of gel-like vitreous humor, the fluid that fills the back of your eye, casting shadows on your retina.
- Posterior Vitreous Detachment (PVD): This occurs when the vitreous humor pulls away from the retina, often resulting in an increase in floaters and flashes of light. PVD is a common condition, especially in older adults.
- Migraines: Some people experience visual aura before or during a migraine, which can include seeing flashing lights, zigzag lines, or glitter-like patterns.
- Eye Infections: Certain eye infections, such as uveitis, can cause inflammation and irritation, leading to the perception of glitter or sparkles.
- Eye Trauma: An injury to the eye can cause floaters and other visual disturbances.
- Retinal Tear or Detachment: In rare cases, floaters can be a symptom of a retinal tear or detachment, a serious condition that requires immediate medical attention.
When to See a Doctor:
If you experience any of the following, it's important to see an eye doctor promptly:
- Sudden onset of floaters or flashes of light
- A significant increase in the number of floaters
- Floaters that are accompanied by blurred vision, double vision, or pain
- Floaters that obscure your central vision
A comprehensive eye exam can help determine the cause of your glitter-like vision and recommend the appropriate treatment.
