Blue Cut Optical Glass Lens for Anti Blue Light Protection

Sunlight offers a vibrant palette of colors, including red, orange, yellow, green, and blue light rays, each with varying shades. These colors are differentiated by their energy levels and wavelengths, which are forms of electromagnetic radiation. When combined, they create what is commonly known as 'white light' or simply, sunlight.

Without diving into complex physics, there's an inverse correlation between the wavelength and energy of light rays. Light with longer wavelengths holds less energy, while those with shorter wavelengths pack more energy.

Light rays on the red side of the visible spectrum have longer wavelengths and thus contain less energy. Conversely, rays on the blue end boast shorter wavelengths and consequently, more energy.

The electromagnetic rays extending just beyond the red segment of the visible spectrum are known as infrared. These rays are warming yet invisible. For instance, 'warming lamps' at your favorite eatery use infrared radiation to keep food warm. These lamps also emit visible red light to indicate they are active, a feature shared by various types of heat lamps.

At the other end of the visible spectrum, blue light rays with the shortest wavelengths—and thus the highest energy—are sometimes referred to as blue-violet or violet light. This high-energy light is why electromagnetic rays just beyond this spectrum are termed ultraviolet (UV) radiation.
