As people grow older with age, they tend to develop eye floaters, which in their sight are seen as spots, strands or even little flies and may appear to be grey or in a dark color within their vision. These floaters can be spotted in either just one eye or even in both, depending on the circumstances.
Floaters are suspensions within one’s vitreous humor, the thick clear fluid that fills the eye. These floaters can be as a result of the vitreous humor degenerative changes or in some instances accidents that would later cause foreign material to enter the eye’s fluid.
The eye is structured in such a way that the cornea and lens, in the front of the eye, focus light passes through the vitreous humor onto the eye’s retina that is at the back of the eye. Once these floaters develop, they tend to float in the path of light in the vitreous humor, thereby casting what a small shadow on the retina that the patient will later perceive to be a floater.
These floaters are suspended in the eye’s vitreous humor fluid and therefore continue to drift along within the eye following the exact same motion of the eye. They cannot be directly looked at by the patient and do not cause any health dangers to a patient, however, once the number of floaters in a single eye continue to increase in number it is important for one to visit an eye clinic or eye doctor, also known as an ophthalmologist, to diagnose.
The sudden increase in these spots in the eyes can be as a result of retina detachment, where the retina is moved from its normal position at the back of the eye. This condition is very serious and should be handled with utmost care.
Persons who suffer from diabetes are prone to developing floaters and a serious of other eye conditions from glaucoma and also due to the condition diabetic retinopathy that they tend to develop because of the diabetic condition.
Glaucoma, which is caused by an increase in the eye’s intraocular pressure, causes floaters and is not necessarily linked to only diabetic patients. The condition has been linked with excessive use of computers.
Floaters can also be caused by a condition known as macular degeneration where the retina, which is the light sensitive part of eye, begins to deteriorate.
