BLUE LIGHT – ARE YOUR EYES OVEREXPOSED?

BLUE EYES AND YOUR EYES, HOW TO PROTECT

BLUE LIGHT – WHAT IT DOES TO YOU AND HOW TO PROTECT YOUR EYES?

Blue light has dual characteristics – a healthy side but it has also a dark side.

Healthy Blue light, in its natural form from the sun:

  • Allows us to differentiate between day and night
  • Manages our circadian rhythm; both when we are awake and during our sleep
  • Improves our cognitive performance and keeps us alert.

So, how Blue light tumbles into the dark side, affecting your eyes?

  • Light emitting diodes (LED) emits BLUE LIGHT and is found in virtually all light emitting appliances such as fluorescent lamps, computer screens, laptops, mobile phone screens and tablets.
  • Wavelengths within the blue-violet portion ( 415 to 455 nanometers) of the light spectrum are considered to be most harmful to the retinal cells. Most of the devices that we use emit a high level of blue light, wavelength that starts around 400nm.
  • It turns you into a night owl. An over exposure of blue light from digital devices during the evening will block the release of melatonin, a hormone released during the night to reduce alertness to help induce sleep. So after a night of watching TV or being on Facebook or WhatsApp, you may feel like a zombie.
  • A more permanent damage of artificial blue light is a premature degeneration of retinal cells, leading to long term vision problems. Retinal cells process light and colours and once damaged, they cannot be replaced naturally or artificially.
  • Overexposure to digital devices emitting blue light can also contribute to digital eye strain.
