Frequently Asked Questions

Flashes and floaters are common visual symptoms that often occur as part of the natural aging process of the eye. Floaters appear as small spots, cobwebs, threads, or squiggly lines that drift across your field of vision, while flashes may look like brief streaks or flickers of light.Most floaters develop when the vitreous gel that fills the inside of the eye begins to shrink and separate from the retina, a process known as posterior vitreous detachment (PVD). This is a common age-related change and is usually harmless. Flashes occur when the vitreous gently pulls on the retina during this process.Although many cases are benign, flashes and floaters can sometimes indicate a retinal tear or retinal detachment, making a prompt eye examination important—especially if symptoms appear suddenly.

Yes. Eye floaters are very common, particularly after age 50, and most are a normal part of the aging process.Many people notice a few floaters when looking at a bright sky, a white wall, or a computer screen. Over time, the brain often adapts, making them less noticeable.However, a sudden increase in the number of floaters, especially when accompanied by flashes of light or changes in vision, should never be ignored. These symptoms require prompt evaluation by an ophthalmologist to rule out a retinal tear or retinal detachment.

While occasional floaters are often harmless, certain symptoms require immediate medical attention.You should contact an ophthalmologist or seek emergency eye care immediately if you experience:A sudden shower of new floatersFrequent flashes of lightA dark curtain or shadow moving across your visionSudden loss of peripheral (side) visionBlurred or decreased vision following the onset of flashes or floatersSymptoms after an eye injuryThese symptoms may indicate a retinal tear or retinal detachment, both of which require urgent treatment to reduce the risk of permanent vision loss.

Yes. Although flashes and floaters are often caused by normal age-related changes, they can also be early warning signs of a retinal tear or retinal detachment.A retinal tear occurs when the vitreous pulls strongly enough on the retina to create a small break. Fluid can then pass through the tear, causing the retina to separate from the back of the eye—a condition known as retinal detachment.Because retinal detachment can lead to permanent vision loss if not treated promptly, anyone experiencing sudden flashes, numerous new floaters, or vision changes should have a comprehensive dilated eye examination as soon as possible.

Retinal detachment is a serious eye condition that often develops suddenly and requires immediate medical attention.Common symptoms include:A sudden increase in floatersBright flashes of lightA dark curtain or shadow moving across part of your visionLoss of peripheral visionSudden blurry visionA noticeable decrease in visionRetinal detachment is typically painless, so the absence of pain does not mean the condition is less serious. Early diagnosis and treatment offer the best chance of preserving vision.

Yes. Retinal detachment is considered an eye emergency. Without prompt treatment, the detached retina can lose its blood supply, resulting in permanent and irreversible vision loss.If you notice a sudden increase in flashes or floaters, a curtain or shadow over your vision, or sudden vision loss, seek emergency ophthalmic care immediately. Do not wait to see if the symptoms improve on their own.At LifeviewMD, we provide comprehensive eye examinations to evaluate flashes, floaters, and other sudden vision changes. Our goal is to quickly identify retinal tears, retinal detachment, and other sight-threatening conditions so that timely treatment can be initiated when necessary.
