Why Should You Add Blue Light Block to Your Eyeglasses


2020 has been a year of
changes. Most of us has been pushed to spend more hours in front of our
electronic devices, more specifically our computers. The old average hours
spent in front of a screen was 7 hours a day, and without any doubt this number
will drastically rise worldwide.

You can experience
exposure to harmful blue light rays through your computer or phone screens, or
out in the sun. The good news is that specialists have opportunely reacted to
the need of people to protect their vision, to combat this and protect your
eyes and prevent vision problems. Blue light
filtering glasses and zFORT™ blue light blockers are some ways to help
combat this issue, especially if you spend a lot of time at the computer.

What is blue light?

Sunlight is made up of
red, orange, yellow, green and blue light rays with different levels of energy
and wavelengths. Blue light rays have short wavelengths between 380nm and 500nm
with high energy levels. Studies have found that when blue light rays reach a
wavelength of between 415-455nm, they could be extremely harmful to eye health
as they penetrate through to the retina.

What are the benefits of blue light and the negatives?

While blue light waves
can be harmful to your eye health, they aren’t all negative. Some blue light
exposure is necessary for improving your memory and mood, regulating your sleep
cycle, and maintaining healthy eye development for children.

On the
other hand, excessive exposure to blue light could pose a threat to your
overall health, including the possibility of causing digital eye strain or
damage to the retina.

Other
negative consequences that people who over expose to blue light experience is
difficulty to sleep, headache or migraine, or in the long term it might even
cause myopia or accelerate presbyopia.
