Flashes can look like flashing lights or lightning streaks in your field of vision. Some people compare them to seeing “stars” after being hit on the head or standing up too fast. You might see flashes on and off for weeks, or even months. Flashes happen when the vitreous rubs or pulls on your retina.
Flashes could be caused by several different factors, such as medications, eye health, injury, and more.
Floaters look like small specks, dots, circles, lines or cobwebs in your field of vision. While they seem to be in front of your eye, they are actually floating inside. Floaters are tiny clumps of gel or cells inside the vitreous that fills your eye! What you see are the shadows these clumps cast on your retina.
