I am an expert in the field of ophthalmology with a focus on retinal health and vision science. It is my pleasure to provide you with a comprehensive answer to your question.
Bright flashes of light in the peripheral vision can be caused by a variety of factors, but they are often related to the health of the retina and the vitreous humor, which is the jelly-like substance that fills the inside of the eye. Here's a detailed explanation:
1. Vitreous Separation: As we age, the vitreous humor can start to shrink and pull away from the retina, a process known as posterior vitreous detachment (PVD). This can cause small arc-like momentary flashes of light in the peripheral vision. The vitreous pulling on the retina can create the sensation of seeing a light, but it is actually the movement of the retina that is being perceived. These flashes are typically harmless and resolve on their own over time.
2. Vitreous Floaters: Along with flashes, the presence of floaters is another common symptom of vitreous degeneration. Floaters are small specks or cobwebs that move in your field of vision and are shadows cast by the vitreous gel or clumps of cells on the retina.
3. Retinal Tearing: While rare, bright flashes can be a symptom of a retinal tear. The vitreous pulling on the retina can cause a tear, which can lead to flashes of light. If a retinal tear occurs, it is a serious condition that requires immediate medical attention to prevent retinal detachment, which can lead to vision loss.
4. Ocular Migraine: Some individuals may experience visual disturbances such as bright flashes of light, known as an aura, before the onset of a migraine headache. These visual symptoms can occur in the peripheral vision and are related to changes in blood flow in the brain.
5. Macular Degeneration: In some cases, bright flashes can be an early sign of age-related macular degeneration (AMD), a disease that affects the central part of the retina responsible for detailed vision.
6. Retinal Detachment: If the retina becomes detached from the back of the eye, it can cause sudden and severe flashes of light. This is a medical emergency and requires immediate treatment.
7.
Posterior Vitreous Detachment (PVD): This is a common cause of floaters and flashes of light. The vitreous gel condenses and contracts, causing it to pull on the retina and create the sensation of light flashes.
8.
Glaucoma: Although less common, bright flashes can also be an early symptom of glaucoma, a condition where increased pressure in the eye damages the optic nerve.
It is important to note that while many of these causes are not serious and resolve on their own, some, like retinal tears and detachments, require immediate medical attention. If you experience frequent or persistent flashes of light in your peripheral vision, it is advisable to consult an ophthalmologist for a comprehensive eye examination.

Small arc-like momentary flashes of light in the peripheral vision are commonly experienced during vitreous separation. The vitreous pulls on the retina which makes one think they are seeing a light but it is caused by movement of the retina. ... Rarely flashes are associated with a tear in the retina.
