These Contact Lenses Turn Dark in Bright Sunlight
​

A unique additive will automatically darken the lenses when they're exposed to bright light, the FDA explained in a statement. The lenses will clear up whenever they're back in normal or darker lighting conditions.

 

They have auto darkening glasses - why not auto darkening contacts?! The thing with the glasses is that they take a few minutes to return to light when you walk into a dark room. I'd imagine contacts made the same way will respond the same way. Just might bring back the eye patch like Pirates used to wear. They wore them to keep one eye adjusted to the dark conditions down below deck. If they found themselves in a fight they had the advantage of flipping up an eye patch while the other guy was struggling to see in the dark.

Do you know why they drank a lot of rum?

I'm not sure if this is rhetorical, and I don't know 100%, but I'd imagine it was a way to have non-stale water (for flavor), and to help keep their water/fluid supply relatively clean (because alcohol). That's just a guess though, to be honest.

 

Actually, the newer plastic photo-sensitive lens adapts much faster. Plus, you can get them in various degrees of darkening. My old glasses took several minutes to fade out indoors, but I don't notice it at all with the newer plastic lenses. I just wish they could polarize as well.

 

I think the iris in an eye adapts slowly to brightness and darkness so that you can see a blinking warning LED.

Yup! Water in wooden barrels would go rancid and be unpalatable. Alcohol wouldn't.

 

Basically @Tonyr1084 has it. Water wouldn't keep, so Rum was the choice of seamen.

There's a joke in there, somewhere!

 

Scientists love breadboards!

This kludgy network of electrical resistors can learn to recognize flowers, among other artificial intelligence tasks.

That picture will give ag a headache.

 

No it won't, no 741's involved.

 

 

 

 

 

 

Recently, I found it cool.

I liked the way it walked through the stairs and operated the elevator.
