An ophthalmologist warned of a dangerous number of "floaters" in the eyes. If there are a lot of unusually visible elements, you should immediately consult a doctor - a vessel may be ruptured. "Flashes" in the eye may indicate a retinal detachment, said Anna Rusanovskaya, a candidate of medical sciences, on the "Moscow Speaks" radio station. As a rule, this is the destruction of the vitreous body. The inside of the eye is filled with such a gel, and there are destructive, transparent elements there, and we can distinguish them against a white background, which is normal. If you usually noticed 2-3 flies, and suddenly you woke up in the morning and there were a lot of them - 200-300, then you need to see a doctor, preferably on the same day. If the number of floaters increases, there may have been a tear in the vessel, and these extra floaters are drops of blood in your eye. And if you have a light that goes on and off in your eye, so-called "flares", then you may have tension in the retina - the vitreous body in places where it is firmly attached is pulling on it, and a tear is about to form. And at this stage you can prevent retinal detachment by performing laser coagulation of the retina in this area and this will save your eye.
