Flashing lights at side of eye
Flashing lights at the side of the eye can be a concerning symptom, but it is important to remember that they are not always a sign of a serious underlying condition. In most cases, flashing lights at the side of the eye are caused by a harmless condition, such as floaters or vitreous detachment. However, it is important to be aware of the more serious conditions that can cause flashing lights at the side of the eye, such as retinal detachment and eye infections.
- Floaters
- Retinal detachment
- Vitreous detachment
- Migraines
- Eye infections
- Ocular hypertension
- Brain tumors
- Stroke
- Multiple sclerosis
If you are experiencing flashing lights at the side of the eye, it is important to see a doctor to rule out any underlying medical conditions. Treatment for flashing lights at the side of the eye will depend on the underlying cause.
Floaters
Floaters are small, dark shapes that appear in your field of vision. They are caused by tiny pieces of gel or debris that float in the vitreous humor, the clear gel that fills the inside of your eye. Floaters are usually harmless, but they can be annoying, especially if they are large or numerous.
Floaters can be a symptom of flashing lights at the side of the eye. This is because floaters can cast shadows on the retina, which can be perceived as flashes of light. Floaters can also be a sign of a more serious condition, such as a retinal detachment. If you are experiencing flashing lights at the side of the eye, it is important to see a doctor to rule out any underlying medical conditions.
There is no cure for floaters, but there are some things you can do to reduce their visibility. These include:
- Wearing sunglasses to reduce the amount of light that enters your eyes
- Using artificial tears to lubricate your eyes and help to keep floaters from sticking to the retina
- Getting regular eye exams to monitor your eye health and to rule out any underlying medical conditions
In most cases, floaters are harmless and do not require treatment. However, if you are experiencing flashing lights at the side of the eye, it is important to see a doctor to rule out any underlying medical conditions.

| Treatment includes wearing sunglasses, using artificial tears, and getting regular eye exams | Treatment for flashing lights at the side of the eye will depend on the underlying cause |
Retinal detachment
Retinal detachment is a serious eye condition that can lead to vision loss. It occurs when the retina, the light-sensitive tissue at the back of the eye, separates from the underlying layer of tissue. This can happen due to a number of factors, including trauma, eye surgery, and certain medical conditions.
Retinal detachment is a medical emergency. If you experience any of the symptoms of retinal detachment, such as flashing lights at the side of the eye, floaters, or blurred vision, it is important to seek medical attention immediately.
Flashing lights at the side of the eye are a common symptom of retinal detachment. This is because retinal detachment can cause the retina to tear, which can lead to bleeding and inflammation. The bleeding and inflammation can then cause flashes of light to appear in the field of vision.
Retinal detachment is a serious condition, but it can be treated if it is caught early. Treatment for retinal detachment typically involves surgery to reattach the retina to the underlying layer of tissue.

| Retinal detachment | Flashing lights at the side of the eye |
|---|---|
| A serious eye condition that can lead to vision loss | A common symptom of retinal detachment |
| Occurs when the retina separates from the underlying layer of tissue | Can be caused by bleeding and inflammation |
| Symptoms include flashing lights at the side of the eye, floaters, and blurred vision | Treatment typically involves surgery to reattach the retina |
Vitreous detachment
Vitreous detachment is a common eye condition that occurs when the vitreous humor, the gel-like substance that fills the inside of the eye, separates from the retina. This can happen due to a number of factors, including age, trauma, and certain medical conditions.
Vitreous detachment is usually harmless, but it can sometimes cause flashing lights at the side of the eye. This is because the vitreous humor can pull on the retina as it separates, which can cause the retina to tear. This tearing can then lead to bleeding and inflammation, which can cause flashes of light to appear in the field of vision.
Flashing lights at the side of the eye are a common symptom of vitreous detachment. However, it is important to note that not everyone who experiences flashing lights at the side of the eye has vitreous detachment. Other conditions, such as retinal detachment, can also cause flashing lights at the side of the eye.
If you are experiencing flashing lights at the side of the eye, it is important to see a doctor to rule out any underlying medical conditions. Treatment for vitreous detachment is typically not necessary, but treatment for the underlying cause of the flashing lights may be necessary.

| Usually harmless, but can sometimes cause flashing lights at the side of the eye | Treatment is typically not necessary, but treatment for the underlying cause of the flashing lights may be necessary |
Migraines
Migraines are a common neurological condition that can cause a variety of symptoms, including flashing lights at the side of the eye. These lights are often described as shimmering, sparkling, or jagged, and they can be accompanied by other symptoms, such as headache, nausea, and vomiting.
The exact cause of migraines is unknown, but it is thought to be related to changes in the brain’s activity. These changes can lead to the release of certain chemicals, which can then cause inflammation and pain. Migraines can be triggered by a variety of factors, including stress, fatigue, certain foods, and changes in the weather.
Flashing lights at the side of the eye are a common symptom of migraines, but they can also be a sign of other conditions, such as retinal detachment. It is important to see a doctor to rule out any other underlying medical conditions if you are experiencing flashing lights at the side of the eye.
There is no cure for migraines, but there are a variety of treatments that can help to reduce the frequency and severity of attacks. These treatments include medication, lifestyle changes, and alternative therapies.
