Q/A ON BLUE LIGHT FILTERING LENSES
I donʼt need prescription eyeglasses, but spend most of
the day on the computer and my smart phone and iPad.
My eyes get to aching by the end of the day. What can
I do?
You are suffering from digital eye fatigue. It is quite
common these days because of all the time we spend
on these devices. The largest shift in humankindʼs his-
tory on our visual environment has occurred. 90% of
Americans use digital devices for two or more hours
per day. 60% use them for five or more hours and 65
percent experience symptoms of digital eye strain. A
recent report states that by the time the average Ameri-
can child reaches age 17, they will have spent over a
third of their lives looking at digital devices which ex-
pose us to unnatural amounts of blue light.
It is well known that blue light in certain wavelengths
has a detrimental effect on visual function. There are
blue light-attenuating lens products on the market now
that diminish the effects of blue light from artificial
light sources to improve visual comfort. These lenses
are available both for prescription and non-prescrip-
tion wearers. The goal is not to block blue light, but to

pass through the lens
My husband spends a lot of time on the computer in
the evening and sometimes works on his laptop in bed.
Could that be causing his problem sleeping?
Circadian rhythm can be thought of as our bodyʼs
way of regulating our sleep-wake cycle. Historically,
human exposure to blue light at night was relatively
low. Daytime exposure to blue light would trigger
our internal clock to be alert and awake. As evening
would fall, lack of blue light was our signal to sleep.
However, with advancement in technology, our eve-
ning exposure to blue light is at levels never before
experienced by mankind. The electronic screen on our
smartphones, tablets, computers, as well as LED and
CFL light bulbs, all emit light which affects our sleep-
wake cycle.
It is generally advised to turn these devices off a cou-
ple of hours before bedtime to allow our internal clock
to do its job.
Next month I will talk about childrenʼs eyes and their
exposure on these devices.
