Here is a simple and informative essay on Blue Light, suitable for students:

Essay on Blue Light

Blue light is a type of light with a short wavelength and high energy. It is part of the visible light
spectrum and is naturally present in sunlight. However, in today’s digital world, we are exposed to
blue light not just from the sun but also from screens—like mobile phones, computers, tablets, and
LED lights.

While some blue light is good for health, as it helps us stay alert and regulate our sleep cycle, too
much exposure—especially at night—can be harmful. Staring at screens for long hours can cause eye
strain, headaches, and sleep problems. It may also lead to a condition called "digital eye strain" or
"computer vision syndrome".

To protect our eyes from too much blue light, we should take regular breaks while using screens,
reduce screen time before bedtime, and use "blue light filter" settings on devices. Some people also
wear glasses with blue light protection lenses.

Scientists are still studying the full effects of blue light on our health. But it is clear that while blue
light is a natural and important part of life, we should be careful about artificial blue light from
screens.

Conclusion:

Blue light is both helpful and harmful. It helps us stay awake and active, but too much of it—
especially from electronic devices—can affect our eyes and sleep. We must learn to use screens
wisely to stay healthy.
