What Are Flashes?

When Are Eye Flashes a Serious Problem?

Flashes may resemble lightning, snow, sparks, stars, flickering, lines, or spots in your vision. They are often caused by the vitreous gel in the eye pulling or rubbing against your eye's retina and optic nerve but may also be associated with your brain. At Harrington Vision in Florence, SC, we provide professional diagnosis and treatment for many eye and vision problems, including flashes.

Migraines Can Cause Flashes

Flashes can be triggered by migraine headaches. You may see peripheral flickers or jagged lines for about 15 minutes before a severe headache occurs. However, it's also possible to have an ophthalmic migraine. This involves seeing flashes without feeling the headache symptoms.

Can You Prevent Flashes?

It isn't always possible to avoid developing this eye condition. Nonetheless, you can take steps to reduce your risk for the condition. To prevent flashes, it's best to exercise regularly, quit smoking cigarettes, avoid overeating and ensure you consume enough vitamins. Take steps to protect your head and eyes. For example, you can wear safety glasses or a helmet while engaging in dangerous activities.

When to See an Eye Doctor

Not all flashes are signs of a health problem. They're a fairly common occurrence, especially as you grow older. However, it's important to let your optometrist know about new flashes and watch for the signs of a serious eye condition.

Be sure to contact an optometry professional immediately if you notice a sudden increase in the frequency of your flashes. Likewise, it's important to tell your eye doctor if you see a gray curtain obscuring a portion of your sight. The same goes for shadows in your peripheral vision.

If your vision becomes narrower or flashes suddenly increase, it may also be a sign of a serious eye problem. Flashes and other changes might indicate that you have a torn or detached retina. This calls for emergency treatment. Brain injuries that cause flashing also need immediate attention.

An eye examination can determine if your eyes need treatment. The eye doctor may have to dilate your eyes and ask questions about flashes, such as when they first began, how frequently they happen, and what they look like.
