>> Ginger: NOW AT 7, BLUE LIGHT-BLOCKING GLASSES, YOU’VE PROBABLY SEEN THEM ADVERTISED
ALL OVER THE INTERNET AND EVEN
SEEN A FEW CO-WORKERS WEARING
THEM WHILE TYPING AWAY AT THEIR
COMPUTER.
SOME SAY IT HELPS REDUCE THE
SYMPTOMS OF DRY EYE AND
INSOMNIA.
DO THEY REALLY WORK?
ADRIANA EVASHINSKI TALKED WITH
EYE EXPERTS IN FLORIDA AND THEIR
ANSWERS REALLY SURPRISED YOU.
>> Reporter: THEY REALLY DID.
EXPERTS RECOMMEND THESE BLUE
LIGHT-BLOCKING GLASSES FOR
PEOPLE WHO SPEND A TON OF TIME
IN FRONT OF A COMPUTER SCREEN,
BUT WE SPOKE WITH DOCTORS WHO
CONFIRM THERE’S NO MEDICAL PROOF
THAT SHOWS EXPOSURE TO BLUE
LIGHT CAN HURT YOUR EYES.
BLUE LIGHT IS EVERYWHERE, FROM
THE SUNSHINE OUTDOORS TO
FLUORESCENT LIGHTING AND L.E.D.
WITH ALL THIS EXPOSURE, EYE
EXPERTS CONFIRM THERE’S NO
MEDICAL DATA THAT PROVES IT CAN
DESTROY YOUR VISION.
>> BEING A RETINA SPECIALIST,
ONE OF THE BIG CONCERNS IS DOES
IT ADVANCE OR CAUSE MACULAR
DEGENERATION?
WE DON’T KNOW FOR SURE.
>> Reporter: THE DOCTOR IS NOT
ONLY AN OPHTHALMOLOGIST, HE’S A
RETINAL SURGEON IN ORLANDO.
HE SAYS THERE HAVE BEEN A LOT OF
STUDIES TO SEE HOW EXCESSIVE
EXPOSURE TO BLUE LIGHT AFFECTS
THE HIGH, THERE’S NO PROOF IT
DOES.
>> THE ONLY DATA THEY HAVE IS
EXPOSURE TO BLUE LIGHT AFTER THE
SUN GOES DOWN CAN AFFECT A
PERSON’S ABILITY TO FALL ASLEEP.
>> THERE IS EVIDENCE THAT BLUE
LIGHT PROBABLY DISRUPTS
CIRCADIAN RHYTHMS.
SO OUR NORMAL SLEEP CYCLES.
WE’RE ON OUR PHONES, CHECKING
OUR E-MAILS, RIGHT BEFORE GOING
TO BED.
THERE WERE STUDIES THAT SHOWED
THERE WAS A DECREASE IN
MELATONIN PRODUCTION.
>> HE JUST STARTED USING
PRESCRIPTION GLASSES THREE
MONTHS AGO AND OPTED TO GET THE
BLUE LIGHT BLOCKING TINT FOR HIS
SPECKS.
HE SAYS THE GLASSES HAVE BEEN A
GAME CHANGE FOR HIM.
>> IT HAS HELPED OUT WITH MY EYE
STRAIN A LOT.
I’M NOT GETTING AS MANY
HEADACHES AS MUCH.
>> Reporter: BUT THERE ARE
THINGS YOU CAN DO TO REDUCE YOUR
COMPOSURE TO BLUE LIGHT.
ONE IS TO TAKE FREQUENT BREAKS
FROM YOUR COMPUTER AND YOUR
PHONE.
THE OTHER IS TO USE BLUE LIGHT
BLOCKING SCREENS ON YOUR
COMPUTERS AND A BLUE LIGHT
BLOCKING PHONE.
>> THERE’S NOTHING WRONG WITH
USING THEM FOR MEDICAL BENEFIT.
>> Reporter: THERE’S ALSO THINGS
LIKE EYEDROPS AND EYE WASHES
THAT CAN HELP YOUR EYES IF YOU
EXPERIENCE DRY EYE AND EYE
STRAIN, A GOOD OPTION IF YOU’D
RATHER NOT WEAR GLASSES AT ALL.

WORK.
IN THE OLD DAYS WHEN THE SUN
WENT DOWN, WE DIDN’T HAVE ALL
THIS EXPOSURE.
>> Reporter: WE HAVE IT ON TVs
AND EVERYTHING ELSE.
ON YOUR PHONE, YOU CAN GET A
FREE APP TO DO IT.
I DON’T LIKE IT.
I’VE DONE THE NIGHT MODE IS WHAT

I’M NOT A BIG FAN OF IT.
I DON’T LIKE THE REVERSE, A
BLACK OR WHITE WRITING AND
ORANGE WRITING.

USED TO.

LIKE.
