Causes for black spots in vision...

*Description of black spots:

Black spots which are also known as "floaters" appear in the eye and they can be of any size and shape. Do not become alarmed if this should happen to you...floaters are not harmful and it's probably a process which is related to aging. If there is an unusual occurrence of these spots, it may be connected to an underlying cause of a medical condition of the eye and you should see an ophthalmologist as soon as possible. These black spots floating in your eye may last for 10 to 20 minutes or longer. I live with floaters every day and they can be very aggravating especially at night if you are driving. I also have a problem with them bothering me when it is a cloudy overcast day and then they seem to appear for an unknown reason and it's as though they're magnified.

*Causes of black spots:

The eyeball contains a gel-like substance inside of it known as vitreous and it is located between the lens and retina and attachs to the retina. If there is any damage done to the vitreous, it causes a shadow to form on the retina and this shadow causes the appearance of black spots in the eyesight. Listed below are some factors which can cause harm to the vitreous and result in black spots too:

(1)  Surgeries:  There's a variety of surgeries that could be the cause for the black spots in a person's vision. These surgeries consists of surgery for cataracts and laser eye surgery. The cataract surgery carries a high risk of causing a vitreous detachment which lead to black spots.

(2)  Infections:  If debris from bacteria and lymphocytes are caught in the vitreous, this can disturb your vision and you may see black spots.

(3)  Migraine:  If you're a person who has migraine's, a neurological condition, this can also cause black spots. Anyone who has suffered a migraine stroke is also known to have black spots too.

(4)  Posterior Vitreous Detachment:  This is when the vitreous liquefies and contracts and this can cause black spots.

(5)  Aging:  Most people who are aging will suffer from floaters and this is because the vitreous begins to deteriorate and liquefy. This causes a formation of clumps of protein in the fluid and as they begin to float in the eye, the appearance of black spots occur.

Any problem out of the ordinary pertaining to the eye should never be ignored without getting an ophthalmologist check-up.
