The rise of the digital age has come with various challenges. There are a number of complications that arise with the increasing exposure to digital media. One of the complications comes in the form of digital eye strain. Vision center Lifetime Vision Source sheds light on the importance of blue light protection in today’s world.
The Prevalence of Blue Light
Most devices today are equipped with LED lights that provide a clearer and brighter visual experience while promoting efficient power consumption. However, LED lights also produce blue light. While blue wavelengths of light are actually beneficial during the daytime, your eyes haven’t evolved to withstand extreme amounts of blue light. Anyone who’s ever used a smartphone or watched a flat screen TV has been exposed to blue light.
The Dangers of Blue Light
Your eyes aren’t capable of blocking or even reflecting blue light. Every time you are exposed to LED screens, your retina becomes damaged. Blue light kills off light-sensing cells that are vital to your ability to see fine details. The damage is permanent. This is primarily why your eye doctor warns against the excessive use of digital devices. It also suppresses the production of melatonin, the hormone responsible for inducing drowsiness, especially at night.
Protection Against Blue Light
Since the use of digital devices is necessary for work, school and leisure, exposure to blue light cannot be avoided entirely. However, there are some steps you can take to protect your eyes from the detrimental effects of blue light. You can purchase special eyewear that can block blue light. It’s good practice to not use any devices two to three hours before your bedtime so your circadian rhythm remains intact. Make it a habit to rest your eyes every 20 minutes of device usage.
