"Eye exercises will improve your vision."

"Contact lenses can get lost behind your eye."

"If you sneeze with your eyes open, they'll pop out."

I specialize in medical and aesthetic eyecare.

And today, we will be debunking myths about vision.

A lot of people think 20/20 means perfect vision,

And when we say 20/20 vision, it means that this chart

Some people can actually read even better than 20/20.

But there are so many other components of vision.

there's peripheral vision, there's contrast.

Tsai: And we also check for near-point vision,

And technically, you could have 20/20 vision

which means you have perfect 20/20 vision in the center

Back in 2018, there was a study that came out

that the media picked up on, and they said,

"Oh, blue light is going to damage your retina.

It's going to cause permanent blindness."

What the researchers did in this study was they took cells,

and they found out that those cells died.

The truth is that the cells that they put

in that petri dish were not even eye cells.

and they protect our eyes against blue light.

So there is no proof that blue light damages your eyes.

we would actually have a pandemic of blindness

because all of us are on devices all the time,

children, adults, and it's just not true.

So when you wear a blue-light coating on your glasses,

it does help with light sensitivity and glare

and just generally making you feel more comfortable

it means that that blue blocker's not blocking out

If you look at a screen Tsai: I love those.

So, for example, if I'm having trouble sleeping

I'll wear these at nighttime, two hours before bed,

so it doesn't really interfere with my sleep.

and that's probably also contributing to the eye strain.

I hear this all the time from my patients.

your 60s, 70s, 80s, even 90-year-old patients

Tsai: Sometimes the dinner menu gets harder to read

at the restaurant, and I tell them that's absolutely normal.
