Floaters often look like strands, specks, webs or weird shapes. In actual matter of fact, what you are seeing, or think you are seeing are just the shadows of floaters that are cast on the retina; this happens to be the light-sensitive part of our eyes.
Yoga Therapy for Floaters and Spots
Most spots and floaters in our eye are quite harmless and just a bit annoying. Most of them tend to fade away in time and become less troublesome. Oftentimes, a lot of folks, in a hurry, resort to surgery to remove them, but ophthalmologists are willing to oblige only in the rarest of instances.
On the other hand, sudden appearance of many floaters, particularly if accompanied by flashes or other optical disturbances, just might be indicative of a retinal detachment or some serious eye problem. It is always better to consult your eye doctor immediately in this case. Meanwhile, please practice these Yogasanas (postures), Pranayamas (breathing exercises) and Kriyas (cleansing techniques) with special emphasis on the eye kriyas and exercises mentioned at the end:
