As we all know, high cholesterol, or hyperlipidemia and always can be diagnosed in the old people, is characterized by the presence in the bloodstream of abnormally high total cholesterol. If you want to know does the high cholesterol affect Tehran vision, I just can tell us the answer that the high cholesterol will cause the vision loss up to a certain degree. According to the experts in medical filed, if the high cholesterol lasts long time, the individual will experience a buildup of cholesterol in their vessels and arteries in the form of plaque. On one hand, the buildup of the cholesterol will cause the corneal arcus. Pls relax yourself, because a corneal arcus does not have a influence of your eye vision, and treatment is relatively easy: just typically focused on controlling cholesterol. On the other hand, because vascular disease of the eye is a concern in individuals with high cholesterol, we should pay more attention to it. About in 2008, the medical experts have done a survey and the result show that patient with high cholesterol levels always have an about 2.5-fold higher risk of retinal vein occlusion, and then the blockage of blood supply from the retina leads to vision loss. Consequently, I strongly suggest you ask you to see a doctor and good luck.
