It is possible that you may be going through more stress & fatigue than usual, possibly because exams are nearing in. The eye movement symptoms are indicative of lack of adequate rest and increased stress. It may also be possible that your eyesight needs review due to increased number of hours of concentrating on your studies.

It's common for your eyes to relax or wander while you're trying to understand or recall something. However, if you're experiencing a sudden and persistent inability to control your eye movements, along with headaches and difficulty concentrating, it may be worth seeking medical advice. While I can provide general information that may help you. In the meantime, here are a few general suggestions that may help improve your concentration and alleviate eye strain: 1. Take breaks: Schedule regular breaks during your study sessions to rest your eyes and relax your mind. Look away from your study materials and focus on a distant object to reduce eye strain. 2. Practice eye exercises: Perform simple eye exercises to improve focus and eye control. These exercises involve moving your eyes in different directions or focusing on specific objects. You can find various eye exercises online or consult an eye care professional for recommendations. 3. Ensure proper lighting: Study in a well-lit area to reduce eye strain. Avoid excessive glare from bright lights or computer screens. Consider using a desk lamp with adjustable brightness or using a screen glare filter if necessary. 4. Optimize your study environment: Create a comfortable study environment with good ergonomics. Adjust your chair and desk height, position your study materials at an appropriate distance, and ensure your computer screen is at eye level. 5. Get enough rest and sleep: Fatigue can contribute to eye strain and difficulty concentrating. Make sure you're getting adequate rest and practicing good sleep habits. 6. Stay hydrated: Dehydration can affect your overall well-being, including your ability to concentrate. Drink enough water throughout the day to stay hydrated. 7. Consider an eye examination: If your symptoms persist or worsen, it might be beneficial to schedule an appointment with an eye care professional for a comprehensive eye examination. They can assess your eye health and provide specific recommendations or treatments.
