Diabetes indeed has some effects on eyes. Yet we can't tell whether you got diabetes or not based on twitching. Because there are many causes for twitching, for example, fatigue, stress, alcohol, dry eyes, caffeine, eye strain, allergies and nutrition imbalance. You could think carefully if causes fit you. And as to diabetes, there are some obvious signs, for example, you might lose weight seriously and quickly in a sudden, urination frequency increase, extreme hunger soon after eating, and you feel easy to get tired. Diabetes might affect eyes, causing condition named diabetes retinopathy. It is complication which could lead to blindness. Based on the introduction above, I think it is hard to say whether you got diabetes or not. Your eye twitching might be caused by fatigue or something. You don't have to worry too much. But if you develop any symptoms of diabetes, I suggest you to go to hospital at your earliest. Taking proper and timely treatment is very important. Wish you get better soon.
