Why does watching tv from a very close range causes headache?

There are several reasons why watching TV from a very close range can cause headaches:

1. Eye strain: When you sit too close to the TV, your eyes have to work harder to focus on the images. This can lead to eye strain, which can cause headaches, eye fatigue, and other symptoms.

2. Neck pain: Sitting in an uncomfortable position, such as with your neck craned forward, can put strain on your neck muscles and lead to headaches.

3. Migraines: People who are prone to migraines may find that watching TV from a close range can trigger an attack.

4. Stress: Some people find that watching TV from a close range can be stressful, which can also lead to headaches.

If you experience headaches after watching TV from a close range, it is important to take breaks and sit at a comfortable distance from the TV. You may also want to try adjusting the brightness and contrast of the TV to reduce eye strain. If your headaches persist, it is important to see a doctor to rule out any underlying medical conditions.
