Blue Blockers

What is blue light?

Light is made up of electromagnetic particles that travel in waves. These waves emit energy, and range in length and strength. The shorter the wavelength; the higher the energy. The length of the waves is measured in nanometers (nm), with 1 nanometer equaling 1 billionth of a meter. Every wavelength is represented by a different color, and is grouped into the following categories: gamma rays, x-rays, ultraviolet (UV) rays, visible light, infrared light, and radio waves. Together these wavelengths make up the electromagnetic spectrum.

Human eye is sensitive to visible light. Visible light is that part of the electromagnetic spectrum that is seen as colors: violet, indigo, blue, green, yellow, orange and red. Without getting into complicated physics, there is an inverse relationship between the wavelength of light rays and the amount of energy they contain. Light rays that have relatively long wavelengths contain less energy, and those with short wavelengths have more energy. Blue light has a very short wavelength, and so produces a higher amount of energy. Studies suggest that, over time, exposure to the blue end of the light spectrum could cause serious long-term damage to your eyes.

Where is blue light found?

Blue light is actually everywhere. When outside, light from the sun travels through the atmosphere. Sources of blue light include the sun, digital screens (TVs, computers, laptops, smart phones and tablets), electronic devices, and fluorescent and LED lighting)

Blue light may cause permanent eye damage; may contribute to eye-related degeneration which can lead to vision loss.

Blue Blocker

The blue blocker lens is a virtually clear lens that blocks HEV blue light and provides maximum UV protection with minimal color distortion. It is made with a blue-light-blocking polymer that is directly incorporated into the lens material. This polymer absorbs the blue light, preventing it from passing through the lens to your eye. Because it is a clear lens, Blue blockers can be used with everyday glasses instead of a regular optical lens for all-day protection from blue light and UV exposure.

Benefits of the Blue Blocker lenses:

  • Reduce eye strain
  • Protect your eyes from harmful blue light, ensuring they stay healthy
  • Offer vision clarity

The lenses are for people who:

  • Ideal for people who work on digital screens
  • want to protect their eyes against blue light emitted by lighting
  • are sensitive to strong LED, halogen and xenon lights.
