It can cause changes to the front surface of the eye.

You can get sunburn on the surface of the eye.

There's blue light that comes from the sun, really high energy.

That could potentially cause aging changes inside the eye.

The blue light that comes from your digital screens does not have enough power and has consistently shown in research to not increase the risk of aging eye diseases.

Impacts your sleep.

There's also some claims that blue light can affect your eye strain.

But again, research on blue light glasses, on using devices, shows that blue light does not impact eye strain.

A lot of people will claim that they will.

I have a lot of patients who come in and anecdotally are like, oh, my eyes feel so much better from getting the blue light glasses.

And that could just be placebo effect.

It could potentially be the fact that a lot of blue light glasses will have anti-glare or glare-free protection put onto it.

And the anti-glare is probably improving their focus and they're not having as much glare issues when staring at the device.

But right now, there's still just no concrete evidence showing that blue light is contributing to eye strain.

But then the sleep cycle, we do know that blue light can influence your sleep.

I mean, yeah, I have multiple computer screens open.

I have my phone screen open all day.

The other day I was texting a friend.

I'm like, I've got two laptops open at a coffee shop.

You know, I'm like, I'm doubling down on the blue light here.
