What is Blue Light?

Blue light is a color within the visible light spectrum with shorter wavelengths and higher energy. It emits from any source with visible light, such as the sun, smartphones, and light bulbs.

We are exposed to blue light from the sun every day. This natural blue light is good for our health as it boosts alertness, improves memory, and enhances mood. Moreover, it helps in melatonin production to regulate the natural circadian rhythm and promote better sleep. It is especially essential for children as a lack of natural blue light can affect the growth and development of their eyes.

After dark, we get exposed to artificial blue light emitting from our digital devices. This type of blue light is extremely harmful to our health as it disrupts our sleep cycle by signaling the brain to be alert at night, causing sleep problems.

What are Blue Light Blockers?

Blue light blockers are glasses or screen protectors that help reduce exposure to artificial blue light emitted from digital devices, such as televisions, smartphones, laptops, and more. They filter blue light and prevent it from reaching the eyes. Blue light is associated with many eye problems, such as eye strains, retina damage, and an irregular sleep cycle. Blue light blockers help to mitigate these problems by filtering blue light.

Types of Blue Light Blockers


  1. Blue light filterscan be placed on the screens of different digital devices to limit exposure to artificial blue light. They are available for different devices, such as monitors, laptops, smart phones, and iPads, to prevent blue light from harming the eyes while providing a clear screen view.
  2. Anti-blue light glassescan filter high-energy visible (HEV) light emitted from digital devices using different materials or coatings, such as an anti-reflective coating. You can wear them while working on digital devices at night to filter blue light from reaching your eyes.
