Floater:A floater is a blurry spot that appears to drift across your field of vision without actually obstructing it. This blur results from debris within the eye casting a shadow. The image you see is caused by a protein deposit floating in the vitreous, the clear, jelly-like substance occupying the eye's center. People often describe floaters as spots, strands, or tiny flies. Typically, floaters are harmless and occur when the vitreous gel separates from the retina, a condition known as posterior vitreous detachment (PVD). Although PVD is common, it can sometimes lead to retinal tears. If new floaters appear, especially accompanied by flashes of light, it's crucial to have an eye examination to rule out any retinal tears.While no treatments exist for floaters, they generally become less noticeable over time. Even though floaters are often not linked to serious eye conditions, the sudden appearance of new ones warrants an eye check-up. Persistent or recurring spots in the same area of your vision might signal cataracts or another serious eye issue. If you notice a shadow or curtain affecting any part of your sight, it could indicate a retinal tear that has progressed to a detached retina. In such cases, it is critical to see an ophthalmologist immediately, as prompt treatment is essential.
