Try moving your eyes up and down to move them out of the way. Often, floaters will fade away over the years or you will get used to them. See your ophthalmologist if you notice new floaters. Flashes are much like the sensation you have if you are suddenly hit in the eye. You see stars of flashes of light.
Flashes occur when the vitreous shrinks and pulls on the retina.
This causes the sensation of flashing lights. They can occur for several weeks of months, which is more common in older people. If flashes occur suddenly, it could indicate a torn retina, which requires immediate attention from your ophthalmologist. Migraine headaches are caused by a disturbance in the blood flow of the brain. Sometimes, people have visual disturbances associated with migraine, which can resemble flashes.
