My dear friend, it may be due to eye sight problem. Consult any ophthalmologist. Once you should go for CT brain and CBC, if it is not related to eye problem. Other cause may be Anemia or Migraine. 1st visit ophthalmologist. If it is not due to eye sight problem then we can cure both Anemia and migraine with some very effective herbal medicine without any side effects. Very effective herbal drugs are available in market for Anemia and migraine. Migraine will take some time in recovery but definitely you will get root cure.
