The Science of Seeing | Sight: The Story Of Vision | Spark 

Incredibly well done and wide ranging documentary about the loss of vision, its socioeconomic impacts, and some of the science being done to reverse vision loss. Looks like this was originally filmed in 2016 (in the end credits), but this is still amazingly up to date in its coverage of the topic. Highly recommended.

I'm a big fan of your productions. Well-written, presented and informative.

This is an excellent documentary on a very important subject.

Great people and great research.

I love Nebula as a service. The Android version of the app on my s21 is pretty awful. So i normally watch on RU-vid, even though I could watch on Nebula. That said, I love your content enough that I keep coming back. Thanks for covering this.

thanks for Helping the Blind. see the Good in the world. amen.

15:07 im pretty sure he said "before, when i looked at the clouds it hurt his eyes"

Great news on here ❤️

For most of my life things far away weren't sharp and i have a prescription to fix that which I don't really use because I don't actually require it to see, it's not that bad. [I want to maintain my eyes muscle memory] As I have gotten older things close up have gotten much harder see such as fine print. Yesterday I was working on circuit board up close for a few hours and I noticed after when I went to look into the regular world, my vision was extremely blurry and it to quite a while for my eyes to train to see with my normal, everything was blurry double vision. I actually had to put on my glasses for a few hours while my eyes re-adjusted. I'm almost 60 and I will keep pushing without glasses for as long as I can.

Will they be able to fix amblyopia?

Thank you dnews

This must be the biggest opthomolists' confidence trick, since Fairy floss was created in a side show.

Science fascinates me. 54:55

This is all that I need that explains why I need to have an opthomologist do further damage to my eyes

The sad part is that the more computers, handheld devices and blue lights in general that we work with just makes our vision worse. Unless they can fix that problem, people will need glasses at younger ages.

I don't see how it could be any clearer

17:00 Math is hard

PS if you were to tear the wings off a fly would it then be a "walk" or perhaps a "crawl"?! Or is it just a fly with an ironic body. Hmmm..... Science is neat!

There are some seriously misguided comments here.

THUMBS DOWN FOR TO MANY, ...AD"S.

Is this bullshit to make an opthomologist a billionaire.

a third of all humans are dorks
