Black spotsin vision as a result of the aging process
If theperson experiencing the black spots in vision is over 50 years of age, thenthey may as well relax because this is a fairly common consequence of the agingprocess. The black spots that this group of people experiences are called eyefloaters, which are the kind of tiny specks floating in the field of vision. Thereason this happens is due to the shrinking of the eyeballs which is quiteinevitable in that particular stage of life. So the thing that happens is thatwhen the eyeballs shrink, the fluids in them become too excessive and they arebound to split. That means that half of the fluid remains clear and the otherhalf becomes a sort of ropey waste. This waste is what is known as the term eyefloaters in medicine.
Black spotsin vision as a result of posterior vitreous detachment
Vitreousdetachment is sort of a condition in which the glassy body that covers theretina, which is a very important membrane that covers the inner eye and isconnected to the brain through the optic nerve, separates from it. This is notlikely to happen for no reason whatsoever, but it is rather caused by someinflammatory conditions which are not necessarily related to the eye. Theyinclude a kind of trauma or injury, diabetes, a more serious case of myopia orthe previously-mentioned old age. Once posterior vitreous detachment occurs,the vitreous, that is, the glassy body, is likely to turn into liquid, causingthe floaters in the eye which manifest themselves as black spots in vision.
Black spotsin vision as a result of an eye infection
