### Understanding Blue Light and its Effects on Eyes:

![Visible Light Spectrum](https://winsides.com/wp-content/uploads/2024/07/Visible-Light-Spectrum-1024x576.webp "Visible Light Spectrum")
_Visible Light Spectrum_

Blue light is a part of the **visible light spectrum** , with wavelengths ranging from approximately **380 to 500 nanometers**. It has the **shortest wavelengths** and the highest energy among visible-light colors. Sources include **Sun Light** , **Digital Screens** , **LED** , **Fluorescent lighting** , and more.

1. **Spending long hours** in front of screens can lead to digital eye strain or computer vision syndrome, characterized by discomfort, dryness, and fatigue.
2. The intensity of the **high-energy blue light scatters** more easily than other visible light, making it harder for the eyes to focus. This constant refocusing effort can cause strain.
3. Blue light exposure, especially **before bedtime** , can interfere with the production of **melatonin** , a hormone that regulates sleep. Reduced melatonin can lead to difficulty falling and staying asleep.
4. Excessive blue light exposure at night can disrupt the **natural sleep-wake cycle** , affecting overall sleep quality and leading to **daytime fatigue**.
