A few days ago I've experienced headaches accompanied by a dull pressure above my eyes. It wasn't painful, but it was very difficult to focus on activities.

Recently the headaches have went away however my eyes still feel really fatigued even after getting sleep. I've also become mildly sensitive to light. My vision hasn't been affected, however my eyes are very tired after reading, or working on the computer, and I've had some difficulty focusing.

Does anyone know what my problem could be? Thanks for any help.
