Flash Of Light In Peripheral Vision

How Can You Protect Your Eyes

What are flashes and floaters?

Annual eye exams can help your doctor spot changes in your vision before they cause significant problems. Your doctor can dilate your pupils to allow for examination of the back of the eye, and they can check eye pressure to make certain glaucoma is not developing. Keeping these appointments is one of the best ways to protect your eyes.

You can also check your vision at home between visits. The organization Fighting Blindness recommends that you do the following:

  • Look straight ahead, and check your vision.
  • Look to the side, and check your vision.
  • Note the placement and presence of floaters and flashes.
  • Check the other eye.

Bring your notes with you to your appointment, and talk with your doctor about anything unusual you’ve seen.

Never be afraid to talk with your doctor about your symptoms and your concerns. Your doctor’s job is to keep you healthy, and open communication can help make that happen.

Why Do I See Rings Or Flashing Lights In My Field Of Vision

If you see flashes of light in your peripheral vision, or you notice rings of light or halos in your line of sight from time to time, it is wise to book an appointment with your optometrist.

What could flashes in my vision mean?

There are a number of reasons why you may see what appear to be flashes of light. In many cases, halos and glare occur in your field of vision when there is a sudden change in light – for example, if you come out of a dark cinema into the bright sunlight. This is a normal response to bright lights, and will fade as your eyes adjust to your new surroundings. For some people, flashing circles in their peripheral vision go hand-in-hand with severe headaches or migraines. Make note of any other symptoms – like headaches – you are experiencing, as this can help your optometrist make an informed diagnosis. Flashes and lights could also be a sign that your glasses or contact lens prescription needs to be changed – as soon as your vision is corrected, the problem will likely disappear. If you are seeing halos in your field of vision, this could also be a symptom of cataracts. Others may experience flashing, rings of light or halos as a result of problems with the vitreous, which is the gel-like fluid inside your eye that liquefies with age. Sudden flashes could indicate a very serious issue – retinal detachment – which should be treated as an emergency.

What can I do to treat my symptoms?

What Could Cause It

When your eyes are healthy and working well, the only flashes you see come from outside your body. When you see them in your visual field but others can’t see them, you could be dealing with an eye illness or another health problem.

Flashes in your eyes are often caused by both eye-specific issues and general health issues.

Eye Issues:

  • Retinal detachment. A small slice of tissue in the back of your eye transforms light into images. The retina needs a steady flow of blood to work right, and when that is interrupted through a tear, your information flow breaks down. Your brain interprets the break as a flash of light. This is a medical emergency, as the longer the tear remains, the more likely it is that you will have permanent vision loss.
  • Shrinkage of vitreous humor. A thick, gel-like substance keeps your retina in place. As you age, that material gets smaller and smaller. Sometimes, it tugs on the retina, and that can lead to flashes and sparks. This is a common problem, says Harvard Medical School, as about a quarter of people have shrinkage by age 60. But in about one person in six, the reduction leads to retinal detachment.
  • Hemorrhage. Blood nourishes every cell in your body, and in your eyes, it’s delivered by tiny little vessels that line the eye socket. If one of those capillaries breaks, blood can leak into the space behind your retina, and that can lead to retinal detachment and flashes of light.

How Do You Treat Eye Floaters

The most common treatment for eye floaters is not to treat them at all. Even though they can be annoying and bothersome, eye floaters are usually harmless. They usually drift out of your line of sight and you stop noticing them over time. This can be frustrating for people who notice the eye floaters dancing across their view often, but its the safest option in most cases.

Eye Floater Surgery

There is a surgical option for removing floaters, but it involves a lot of risk to your vision. In cases where there are a lot of floaters and theyre starting to impact the way you see, a procedure called a vitrectomy can be used to remove them. This surgical procedure involves using incisions to remove the gel-like vitreous from inside your eye. The vitreous is then replaced with a solution that mimics the vitreous. There are several risks involved in this procedure, including:

  • Developing retinal detachment.
  • Not getting all of the floaters out of your eye.
  • Developing cataracts.

Damage to your sight is a risk of this surgery. For this reason, many providers will carefully discuss all pros and cons of this elective procedure before deciding on this treatment path.

Sometimes your provider may also use a laser to treat floaters. This can break up groupings of floaters, helping move them out of your field of vision. This procedure also has possible side effects.

How To Diagnose Pvd

What Causes Flashing Lights In One Eye

Although PVD is common, its important to see a doctor if you develop new floaters or flashes. These could be the result of PVD or a retinal detachment. Your doctor may need to perform a diagnostic test in order to determine your condition.

A dilated eye examination can confirm PVD, a retinal detachment, or other eye problem. During the examination, your ophthalmologist or optometrist puts special drops in your eyes. These drops widen your pupils and allow your doctor to see the back of your eyes. Your doctor can then examine the entire retina, the macula, and your optic nerve.

The examination lasts about 30 minutes. It can take a few hours for the dilation to wear off. Bring a pair of sunglasses to put on after your appointment, as sunlight and bright lights may be uncomfortable.

What Kind Of Surgery Is Done For It

Surgery is the only way to reattach the retina. There are many ways to do the surgery. They include:

Pneumatic retinopexy.

The doctor injects a gas bubble into the eyeball. The gas bubble lightly presses the detached retina to the wall of the eye. The eye doctor then uses a freezing probe or laser to seal the tear.

Scleral buckling surgery.

The doctor places a piece of silicone sponge, rubber, or semi-hard plastic on the outer layer of your eye and sews it in place. This relieves pulling on the retina and prevents tears from getting worse.


The doctor removes the vitreous gel from the eye. This gives the doctor better access to remove scar tissue from the retina, repair holes, and push the retina back onto the wall of the eye.

En español | Most people will experience eye floaters in their lifetime, especially as they get older. Theyre those tiny spots or lines that look like theyre in front of the eye, but they are actually floating inside it. Flashes, which look like streaks of lightning, are more common with age, too. Most of the time, neither floaters nor flashes are cause for worry. But under certain circumstances, they require immediate medical attention. Heres what you need to know to protect your vision.

What Age Do Eye Floaters Usually Start To Appear

Eye Floaters and Flashes, Animation.

For most people, eye floaters start to show up in their vision between the ages of 50 and 70. However, you can see the occasional floater any time before then. Those are much less common. You may want to check in with your eye doctor about persistent floaters you see at a younger age because it could be a sign of a more serious eye condition.

Can Eye Floaters And Flashes Be Confused With Other Medical Symptoms

When you are seeing unusual things in your field of vision, it can sometimes be alarming. Floaters are typically harmless, but they can easily be confused with other vision changes like large spots in your vision. These symptoms can be signs of other medical conditions like:

Its always a good idea to reach out to your healthcare provider if you have sudden changes to your vision. This could be especially important if you have a medical history of a condition like diabetes or high blood pressure.

What Are The Treatments For Optic Neuritis

In most cases, you can treat ON with corticosteroids to help reduce nerve inflammation and swelling.

Steroid medication may be taken orally, injected, or administered intravenously. These medications typically come with some side effects, so be sure to talk with your doctor or pharmacist to learn what to expect.

If your ON is the result of another condition, treating that condition will often help to resolve ON. For example, a doctor may prescribe antibiotics if a bacterial infection is causing ON.

Depending on whats causing your ON, treatments can also include:

  • adrenocorticotropic hormone

What The Doctor Does

Doctors first ask questions about the person’s symptoms and medical history. Doctors then do a physical examination. What they find during the history and physical examination often suggests a cause of the flashes or floaters and the tests that may need to be done .

Doctors put a drop of fluorescein stain in the eye and then use a to examine the entire eye.

Are Eye Floaters Normal

Peripheral vision, causes of peripheral vision problems &  treatment

Eye floaters are often a normal and common part of the aging process. As you get older, the fluid within your eyes shrinks. This is normal and doesnt mean that your eyes are no longer healthy. It is important to maintain regular eye exams over time, especially if you are experiencing floaters. They usually arent something you need to be concerned about, but its a good idea to have your eyes regularly checked to make sure there arent any other serious eye issues.

Eye Flashes And Migraines: Whats The Connection

Migraines and flashes often present together. These flashes appear in a similar manner to floaters, looking like flickering lights, but often only on one side of your vision and in a jagged pattern. It will most likely obscure the vision on one side and usually go away after 1020 minutes. It could also be followed by a headache. This type of flash may be caused by a migraine, as it can result from a spasm of blood vessels in the brain.

How Is Retinal Detachment Treated

Surgery is the only way to reattach the retina. Without treatment, vision loss can progress from minor to severe. It can even progress to blindness. Loss of vision can happen within a few hours or days.

This condition needs care right away. How soon you need surgery usually depends on if the retinal detachment has or could spread far enough to affect central vision.

There are many ways to do the surgery. They include using lasers, air bubbles, or a freezing probe to seal a tear in the retina and reattach the retina.

Seeing Flashes Of Light

Streaks of light that appear briefly in your visual field are known as flashers. Some patients compare these flashes to lightning or shooting stars.

It is not uncommon to see occasional flashes of light, and in many cases, there may be no cause for concern. However if you experience frequent, persistent, or increasing occurrences of eye flashers, we recommend that you schedule an appointment with us as soon as possible.

Retinal Tear Or Detachment

Floaters and Flashes


  • Many new floaters or showers of floaters
  • A lot of bright flashes, not improving
  • Sometimes it looks as though a curtain is dropping down over your field of vision
  • Side or sides of your vision become dark
  • Complete vision loss in one or both eyes

The retina receives and organizes visual information and sends it to the brain to interpret what you see. A retinal tear usually occurs from vitreous pulling the retina or from injury to the eye. It causes a part of the retina to separate from the back of the eye.

There is a high risk of the tear getting larger and leading to a bigger separation called a retinal detachment. The initial symptoms of a retinal tear, including flashing lights and loss of vision, are similar to a detachment but tend to be more mild.

Treating retinal tear or detachment

A retinal detachment deprives the retina of oxygen and nutrients and is considered an emergency. Retinal tears may or may not need immediate intervention, depending on symptoms or the size of the tear.

Either way, you should be seen by an ophthalmologist to determine the appropriate treatment and how urgently this treatment must be done.

Seeing Prisms In Your Peripheral Vision

What those thousands of visitors read was that that the effect of these prisms is visible in both eyes, and is more electrical in appearance. With these responses, Dr. Dan B. came to his conclusion, and further explained,

One of the less commonly known features of migraines is that many persons can have this visual migraine phenomenon without actually having headache this is called an acephalgic migraine. The spectrum of severity of headaches among migraine sufferers runs the gamut from no headache to severe, debilitating headaches.

He then suggests that the customer have an eye exam, to make sure that there isnt anything else happening.

What Do Eye Flashes Look Like

Flashes can be described in several ways, including seeing:

  • A bright spot or streak of light.
  • A jagged light that looks like lightening.
  • Bursts of light that look like fireworks or camera flashes.

Some people also compare flashes in your vision to when you hit the back of your head and see bright lights for a few moments.

When To See An Eye Doctor For Eye Flashes

Without an exam, it is impossible to tell if flashes are a result of a clean separation or a retinal tear. Thats why its so important to see an ophthalmologist and have the symptoms evaluated, said Dr. Schuman. In the case of posterior vitreous detachment, if flashes occur, they usually subside immediately when the separation is complete and the vitreous tug is released. However, this can sometime take a few days. To get a complete view of your retina, your eyes will be dilated. Your doctor will look for retinal tears, retinal detachment, and any retinal thinning. If a retinal tear is diagnosed, in some cases it can be repaired with an out-patient procedure like laser treatment or cryotherapy. If retinal detachment is identified, you may need surgery immediately to prevent or minimize permanent vision loss.

As a retina specialist, Dr. Schuman sees an average of two to three patients with eye flashes each week. While the condition is more common for older and extremely nearsighted people, he encourages everyone to be on the lookout for telltale signs of retinal tears and detachment. Knowing that repeated eye flashes are a danger signal could save your vision.

Are Eye Floaters An Emergency

Floaters &  Flashers

Eye floaters are usually not an emergency. If you see the occasional eye floater, it typically isnt something to worry about. You should let your eye care provider know about the floaters and have your eyes checked regularly to make sure there are no other vision issues, but this isnt an emergency.

However, if you suddenly have more floaters than normal, reach out to your healthcare provider right away. This could be a sign of a retinal tear or detachment and it will need to be treated quickly.
