Dear madam, Although blurred vision is not described well in literature as symptom of anemia, I have seen many patients who have this symptom, which gets better after correction of anemia. I send patients to ophthalmologist in any case just to rule out associated eye problems. You may also do the same thing. Transfusion of blood is not the solution for anemia. It is just a temporary measure to bring up the hemoglobin level. We need to evaluate your husband to know the cause of anemia and treat the cause. This would actually solve the problem. Hope I have answered your question. If you have any further questions I will be happy to help. With regards, Dr. Girish Kamat
