[Makda] Our secret shopper is a Marketplace producer and she

but it's the lenses that are the real focus.

[Makda] We're taking a hard look at a filter that's supposed to

[Makda] Blue light-filtering lenses are everywhere online,

but we want to test how the country's big chains are

so we're undercover inside Hakim Optical,

LensCrafters, Vogue Optical, and Hudson's Bay Optical.

We're visiting three stores for each of them.

[Makda] The sales pitch sounds and looks convincing.

[Makda] And then the claims start to sound alarming.

[Makda] At one chain, we even hear the "c" word.

To find out, we're off to Philadelphia to visit one of

Along the way, we meet people spooked by the light from their

I think using the computer or the cell phone for a long time

It can have retina detachment by using it too much time.

so I got my glasses with the blue light lens protecting so

that when I look at my computer screen or my cell phone,

I'm at work, whatever, that it doesn't damage my eyes.

If you look at screens too much, your brain and eyes

[Makda] So we're off to America's oldest eye hospital,

Today it's 15 floors devoted to everything eyeballs.

Yeah, otherwise, your retina looks really great.

[Makda] He's an eye doctor and an eye surgeon.

Dr Garg is also a spokesperson for the American Academy

We keep hearing the same thing about blue-light filter lenses.

It's a new thing, and it's all over the internet.

And I don't know where that's come from and why it's taken off

I can't fault them, because I'm sure they're getting a little

here's three talking points about blue light

[Makda] He understands why we'd buy into this.

you're right, after I use my computer for a bunch of hours,

I can't see really well, they're kind of irritated,

but what's bothering them isn't the blue light,

it's the fact that when they're staring at the screen a lot,

That causes the eye to dry out and when your eyes become dry,

they become irritated and scratchy and tired.

What you should do is just take a break and the American

Academy Of Ophthalmology has this 20-20-20 rule.

Every 20 minutes, take a 20 second break and look 20 feet

off into the distance, and that will break that near staring

that we tend to do when we're looking at the screen.

Tearing your eyes out would be really cool around Halloween,

that we see and I think people are exaggerating stuff.

Well, Jeez, I have these light rays that are little daggers

that are coming into my eyes and poking holes in my macula,

which is sorta what she's making it sound like.

And if I'm trying to sell you something that you don't need,

[Makda] Now on to claims of serious damage to the back of

the eyeball, Dr Garg's passion and specialty.

This whole orange area is called the retina.

The centre of the retina gets a special name.
