Six years ago I had Lasik eye surgery. The doctor told me
before the surgery that one of the side effects may be sensitivity to light. I
didn’t really think much of it until after I opened my eyes for the first time
and realized just how bright everything had become. Would I do it again?
Absolutely. The freedom from wearing glasses and just being able to see the
alarm clock in the morning was more than worth it. Plus now I get to wear some
really awesome sunglasses! However without the anti-glare protection that I had
with my glasses, I started to have a problem.
Fluorescent light and computer screens both can give me a
splitting headache in a very short time if I am not careful. What is the cause?
I discovered it is blue light. There are a plethora of research articles about
blue light, but essentially it is the light within the visible light band that
has the highest wavelength. As a result it travels deeper into your eye. Since
the most common source of blue light is the sun, we all need a little, but too
much can be detrimental to our health. Fluorescent lighting and computer
screens are two sources of blue light that can lead to over exposure. In some
cases, blue light has been linked to serious health issues. The Review of
Optometry published a great article on the link between blue light and macular
here to check it out. Harvard health also published an article on how blue
light affects our circadian rhythm and affects our sleep patterns. Click

I have no doubt that too much blue light can be bad for us.
So what have I discovered to be the cure? Back to glasses. But the good news is
that they are cheap and I don’t always have to wear them or stick my fingers in
my eyes to put in contacts after eating some Flamin’ Hot Cheetos.
If you work on a computer all day, can’t put down your smartphone,
or are a hardcore gamer then investing in a pair of blue light filtering
glasses is definitely something to look into. I prefer Gunnar glasses but there are numerous
vendors that manufacture specialized lenses to help filter blue light. As our
workspaces and homes become more automated and even more of our time is spent
using a computer, tablet or smartphone we are all becoming overexposed to blue
light. The move from standard incandescent lighting to high efficiency lighting
is another contributing factor in nearly every commercial space.
If you or your employees are suffering from headaches or
eyestrain at work, or at home try out some blue light filtering glasses. I
promise you won’t regret it.
