If you have been using your phone constantly at night before bedtime, you have to read this! Parents, please do not let your children use their phones just before they sleep!
Long before humans had artificial lighting, we were met with darkness once the sun sets. Today, we are surrounded with artificial light emitting devices. It is perfectly normal according to social norms to watch television, movies and use the computer just before we sleep. However, that is extremely detrimental to our health in many ways.
What is Blue Light?
Here’s where blue light comes into the conversation. Blue light is also known as high-energy visible light (HEV light), a high-frequency, high-energy light. Our smartphones, tablets, computers and televisions all emit high levels of blue light. Although smartphones produce significantly lesser than larger devices like the television, but we spend more time staring at the smartphone and at a closer proximity while we’re at it. Well, blue light is detrimental to our health if exposed at night, so here are some of the health implications that blue light causes!
1. Age Related Loss of Vision
Blue light has been well known for its implications as a cause of age-related macular degeneration, a leading cause of permanent loss of vision at old age. Blue light causes damage to the macula, a small spot near the center of the retina and the part of the eye needed for sharp, central vision, which lets us see objects that are straight ahead. Blurred spots that grows in size may occur in the line of sight, and objects may not seem as bright as they are.

Especially right before bedtime! Try to have a window of 2-3 hours before sleep, where your eyes are not focused on these devices that produces high levels of blue light. You could try to read a book instead!
3. Download Filter Programs
A quick search on Google or the App store will give you a few options to choose from. These filters block out short-wavelength light (blue light) in the evening, saving your eyes and health.
