4. Eye Strain
Continuously looking at a particular point can cause eye fatigue, which can further lead to tiredness, double vision, and sadly, migraine. Usually eye fatigue occurs because of excessive exposure to bright lights (sunlight or interior harsh lights). People with desk job feel better once they stop working under fluorescent lights. Moreover, the ones using contact lenses or glasses are susceptible to a migraine attack. One should, therefore, avoid straining eyes to look through books, papers, or even computer screens for long times. And when going under the sun, wearing sunglasses can make a huge difference.
