Is it normal i have tired eyes

I wonder what causing my eyes to feel so tired. I feel like I want to sleep, but my body does not feel tired. Even if I have enough sleep from night to morning. Having tired eyes is hard on reading materials and driving. It feels like I put effort into seeing and concentrating but cannot think clearly from trying to concentrate. Tired eyes feel like I need to nap but it does not help and it is time-wasted. Sometimes having tired eyes drains my energy. I cannot figure out what causes it and how to make it better and prevent it.
