There are also tiny, very thin fibers in the vitreous. When these fibers pull on your retina or the gel rubs against your retina, you may see stars. If your retina gets pulled too hard or moves out of its usual position, the result can be a retinal detachment. This can cause you to see stars. It can also cause you to lose all or part of your vision in that eye. A detached retina can often be treated successfully with surgery.
One other cause of stars in your vision is a migraine headache. Not everyone who has migraines sees stars or colorful lights which are also known as aura , but many do. These are treated by ophthalmologists or optometrists, doctors specializing in eye health. Traditional migraine headaches, as well as a blow to the head, can give you a lingering pain in your head to go with your starry visions. A detached retina can also make it seem as though a curtain is being drawn over your vision in the affected eye.
But at your next eye appointment, tell your doctor how often you see flashes or floaters. If you start to see more flashes of light, call your eye doctor right away.
As you get older, your risk of retina problems and vision impairment increases. You tend to see more floaters as you age too. Contact sports, such as football or soccer, boost your odds of getting hit on the head and shaking up your occipital lobe. Even a mild concussion should be evaluated by a doctor. A CT scan is also part of a routine concussion check. A trip to an eye doctor for a possible retina problem will include a thorough examination of your eyes.
