There is inside our eyes a gel that fills it called vitreous, the gel is mostly composed of water and over the decades it grows old. As a consequence of time the part of the vitreous that is not composed of water ends up crystallizing deep in our eyes and disrupting our vision since, when the light enters our eyes, it passes through these obstacles and we can see its shadow, giving the impression of see black spots. In general, flying flies do not present danger, however, sometimes this symptom is a consequence of retinal detachment.



The flying flies are nothing more than the consequence of the aging of the body and it is not necessary to be afraid when they appear, there is no serious consequence of this process of crystallization if not the annoyance it generated mainly to observe very clear landscapes.



This symptom usually appears in people over 45 years of age, with myopia and / or people who have undergone vision surgeries and should only be closely observed in cases of temporary or partial loss of vision or in which the patient perceives any change in vision , since in these cases the flies are probably linked to a retinal detachment. If you are young and are seeing flyflies, this is probably happening because of changes in the collagen fibers in your eyes, in those cases it is necessary to see a doctor because it is not common for young people to have this symptom.



If you have black spots in vision and head color, run to a doctor because your retina is certainly off the hook.

To repair this damage, a surgery called vitrectomy is performed which consists of the partial or total removal of the vitreous gel from the eye so that it is replaced by some liquid substance or a gas suitable for that use. In cases of retinal detachment sometimes the same surgery is also recommended, however, a doctor should be consulted for the situation to be analyzed and for the best treatment to be provided.

The phenomenon, also called Scheerer’s Phenomenon, generates clear or white spots in vision that are actually white blood cells passing in their eyes and can be seen only in clear environments that are not white, like the sky and are not grounds for concern.
Hypertension: Similar to pre-eclampsia, hypertension is capable of causing the patient to have dizziness and black spots as high blood pressure causes obstructions in the blood vessels of the eyes, in which case treatment should be done urgently, as case otherwise the patient may be permanently blind.

Macular Degeneration: This disease damages the macula of the eyes and causes the patient to gradually lose sight if left untreated, linked to aging as well as flying flies and cataracts.
