What is Blue light?

retinal damage

Blue light is one of the types of light that form the whole light, we get from the Sun together with Red, Orange, Yellow, Green, Violet, and Indigo. This is called the e/m spectrum of visible light. In the end, we have UV light that can’t actually be seen by the human eye.

The energy of these waves increases as we go towards the end making Blue Light one of the highest intensity types of visible light. The primary source of Blue is the Sun, but other devices also emit Blue light, they are

  • Computers. 
  • Cell Phones
  • Tablets
  • Television.
  • LED lights
  • Fluorescent screen.

Too much exposure to Blue light could lead to retinal damage. A kid’s eye is less capable of filtering Blue lights as compared to adults and that’s because more Blue light reaches a child’s retina than an adult.

Kids when indoor are exposed less to Blue light than when outdoor. But children who spent most of the time in front of screens are more likely to develop eye strain.

Long Exposures To Blue Light May Result In

  • Eye damage and fatigue, this due to the high energy waves that are absorbed by the cornea. Blue light penetrates straight through and slowly deteriorates the retina.

  • It also decreases the secretion of Melatonin, a hormone that prepares your body for sleep. Scientists have found a correlation between Melatonin deprivation and conditions like cancer, diabetes, and clinical depression.
