Wondering what the black thread like blob is floating around in your vision!
It is called a floater. A floater is a gel like substance in the back of the eye called the vitreous. As you age changes to the vitreous can lead to floaters. They can appear as black dots, lines, cobwebs or blobs. They are caused when the fibers inside the vitreous clump together. If your floater changes in size or occurs more frequently you need to see your Optometrist immediately. Especially if you see flashes of light, lose your side (peripheral) vision, develop eye pain or experience blurred vision or loss of vision.
Most often the floaters are just a nuisance and do not require any treatment. You can move your eyes from side to side and then up and down to move the debris and the floaters will shift.
If you have any questions, feel free to make an appointment with your Optometrist!
