Now,I can tell you confidently and definitely because I have looked for some information and materials. Diet coke can cause blindness and it is that true. That is because aspartame consisted in diet coke have many side effects such as headaches, dizziness, attention difficulties, memory loss, slurred speech and vision problems.
