What Does A Flicker Of Light In Your Eye Mean
Sometimes I see flickering stream of light on the corner of my eye. Is this normal? What does this mean?
Flashes, floaters: Flashes of light occur when the retina is stimulated. As the gel in the back of the eye slowly peels off the retina it can cause a flashing sensation. This may be associated with floaters. Also, people can develop ocular migraines with or without the associated headache. Your condition may be related to either of the above; see an eye doctor either way. ...Read moreSee 1 more doctor answer
Flashes: A bright light in your peripheral field can signify traction (pulling) on the mid-peripheral or peripheral retina. These can be warning signs of an impending or evolving retinal tear/break. Symptoms such as these are best evaluated with a dilated retinal exam. Please see your provider for evaluation. ...Read more
Don't ignore flashes: If you are suddenly seeing flashing lights you should have a dilated retinal examination, particularly if there are also floaters in your vision and if the flashes are brief and recurring.

Can be normal: Darker-skinned people often have areas of pigmentation on their conjunctiva (clear vascular layer over the white). This is normal. You may also have a benign area of degeneration called a pinguecula, which can be caused by sun, dust, and wind. Malignant brown spots on the white of the eye are rare and are usually found in patients much older than you, but if in doubt, get it checked out. ...Read moreSee 1 more doctor answer
Pinguecula: You are probably seeing a normal growth called the pinguecula. These are located next to the cornea (the colored part of the eye), on the nasal and lateral side. They are the eye's callous like the thickening on the palms which protects the eye from wind, dust and irritants. Almost all people have them but they vary in size and thickness. ...Read more
Blue sclera: The most common reason the whites of your eyes (sclera) are blue is because there are areas of the sclera that are thinner than others. In those spots, the underlying pigmented tissue of the inside of the eye shows through and it gives those areas a bluish grey color. Rarely, these spots can be associated with eye problems, so if you're concerned or having other symptoms, then see your eye md. ...Read more
Peripheral vision: Auras are visual manifestations of neurological symptoms. Flashing lights are one type of aura people report seeing, and these auras often appear in either eye. Migraines are a common cause of visual disturbances, such as flashing lights, but these uncomfortable visual symptoms can be the result of other physiological conditions as well. Anxiety, retinal disease, htn, and seizures may be an issue. ...Read moreSee 1 more doctor answer
What does it mean when the whites of someone's eyes have a discoloration(not talking about pink-eye)?
Several things: Depending on the color, shape, size and location, there are several possible causes. Most commonly, yellow "fatty" appearing spots near the cornea (clear part covering the color of the eye) called pingueculae or pterygiae are caused by years of exposure to the elements (sunlight, high winds). Any newly-seen spots should be evaluated by an eye doctor. ...Read moreSee 1 more doctor answer
