|Vitamin D Deficiency And Blurred Vision
Blurred vision can be caused by a number of factors. If the reasons are not obvious, to ascertain the precise cause would often need the skill of an ophthalmologist.
In the case of patients of advancing years, the usual reason is age-related macular degradation which is a progressive decline in sharpness of vision. Sometimes, the formation of a neovascular membrane may occur and this causes bleeding. Such a case would result in a swift loss of vision.
Other causes could stem from illnesses such as diabetes which gives rise to glaucoma that imposes a pressure on the eyes resulting in blind spots, poor night vision and sometimes complete loss of vision on either side. Diabetic retinopathy, a diabetes related disorder, can lead to bleeding in the retina.
Cataracts, again generally age-related, is another common cause which is the consequence of cloudiness over the retina which causes halos around lights, impaired night vision and sensitivity to glare. Eventually a cataract will affect daytime vision as well.
Floaters or flashes of vision could also be a sign of retinal detachment. These come as tiny particles that drift across the eye, a situation that could be harmless and temporary.
Other reasons for blurring could result from strokes, brain tumors, inflammation, infections and a host of other causes.
Certain types of medication could also result in blurring.
As mentioned earlier, the reasons are so many with often similar symptoms. Often only an ophthalmologist can ascertain the precise cause after conducting certain tests.
Vitamin D in itself has no specific benefit to blurred vision except in keeping the overall system in good functioning condition. However one of the main sources of obtaining Vitamin D is by exposure to sunlight which could affect certain people with acute sensitivity to glare.
