What are white flashes in your left eye?

There are many possible causes of white flashes in your left eye, including:

Eye floaters: These are tiny, amoeba-shaped clumps of cells that float in the vitreous humor, the clear, jelly-like fluid that fills the inside of your eye. They are usually not a cause for concern, but they can sometimes be a sign of a more serious underlying condition.

Posterior vitreous detachment (PVD): This is a condition in which the vitreous humor separates from the retina, the light-sensitive tissue at the back of your eye. PVD is a common occurrence that usually happens with age, and it is usually not a cause for concern. However, it can sometimes cause white flashes in your eye, as well as other symptoms such as floaters and blurred vision.

Retinal tear: This is a small tear in the retina. Retinal tears can cause white flashes in your eye, as well as other symptoms such as floaters, blurred vision, and loss of peripheral vision. Retinal tears are a serious condition that can lead to retinal detachment, which is a more serious condition that can cause blindness.

Retinal detachment: This is a condition in which the retina separates from the choroid, the layer of blood vessels that supplies the retina with oxygen and nutrients. Retinal detachment is a serious condition that can cause blindness if not treated promptly. Symptoms of retinal detachment include white flashes in your eye, as well as other symptoms such as floaters, blurred vision, and loss of peripheral vision.

It is important to see an eye doctor right away if you experience white flashes in your eye, especially if you have any of the other symptoms listed above. Early diagnosis and treatment of the underlying condition can help to prevent serious vision loss.
