Different wavelengths of light appear differently to the eyes. Shorter wavelengths are blue or violet, and longer wavelengths appear red. These days, blue light is often talked about in the mainstream media  as exposure to artificial blue light has gone up dramatically because of  the widespread use of electronic devices. Should you be worried about artificial blue light? To know the answer, read the following useful insights on blue light curated by one of the leading retirement homes in Puducherry: 

1. Common sources of blue light include: Sunlight is the main source of blue light. Natural blue light is beneficial during the day as it boosts attention, reaction times, and mood. Common sources of artificial  blue light are: 

  • Fluorescent lights 
  • LED lights 
  • Smartphones
  • Televisions
  • Computer screens
  • Tablets
  • E-readers
  • Video games

2. Blue light can affect the eyes: Often many people experience discomfort after staring at digital screens for hours. Blue light can be one of the reasons behind the digital eye strain. It has been found that when people use digital devices, they tend to blink less. Fewer blinks can mean less moisture. This may cause:

  • dry eyes
  • sore or irritated eyes
  • tired eyes
  • headaches

3. Blue light suppresses sleep-inducing hormones: At night, blue light tricks the brain into thinking that it is still daytime, disrupting circadian rhythm. This leads to fragmented sleep. 

4. Reducing blue light exposure:  Here are some tips to reduce blue light exposure and protect your eyes: 


  • Reduce screen time: Take regular screen breaks. 
  • Stop using electronic devices before bedtime: Set an alarm that reminds you to turn off electronic devices 2 to 3 hours before bedtime.
  • Get new glasses: Computer glasses with special lenses can lower blue light exposure. They can filter blue light and reduce digital eye strain. 
  • Use a filter. Add a screen filter to your smartphone, tablet, and computer.
