New #metasurfaces, ultra-thin materials made of tiny #nanoantennas that can both amplify and control light in very precise ways, could replace conventional refractive surfaces from #eyeglasses to #smartphone lenses and improve dynamic applications such as augmented reality/virtual reality and #LiDAR.

Transitions

My glasses have those transitions lenses. You know, they tint themselves in bright light so they act as sunglasses when needed. When the light is dimmer the lenses un-tint themselves.

Yesterday we got an inch or two of snow. Not much, but enough to need to clean it up. I did a lot of it yesterday when I went out to the store. It snowed enough afterwards that everything was covered again. I went out and shoveled it all this morning, including the path to the side of the house where we keep the trash barrels and in front of the fire hydrant that’s on the end of our property. I also put some ice melt down on the driveway. We’re good to go. Our personal snow removal is complete.

If you’ve ever been outside after a fresh snowfall you know that it is super bright. If the sun is out, it reflects off the snow and everything around you is super bright. The transitions lenses come in handy on days like this.

I’ve been back inside for 15 minutes now and the lenses have yet to un-tint themselves. It’s like I am walking around at midnight with all the lights off.

Fun.

Has anyone had a good experience buying glasses online in the #uk? Looking for recommendations. #scotland #glasses #advice #eyeglasses #recommendations

After some trial and error with eyeglasses I can say: Unless your eyes are worse than mine (and mine are very bad), expensive ultra-thin lenses aren't noticeably better than basic lenses. But OMG is anti-reflective coating key! My vision with the best anti-reflective coating is NOTABLY better than without any anti-reflective coating. So if you can only spend big on one thing, that's what to spend it on. #eyeglasses #glasses #vision

#Eyeglasses, what a spectacular technology!

They meaningfully improve day to day life experience for a bunch of us. I regularly take them for granted. The other day I went for a stroll around the neighborhood without mine, & let me tell you: it sucked.

I should slow down & be mindful to #appreciate stuff like that more often.

I was watching a show tonight. Two characters were having an intense discussion. One dramatically yanked his own glasses off to glare at the other while making his point. This is something I've seen many times in movies and tv shows, but never in real life.

I tried yanking my glasses off to say something forceful to @Knightky . I couldn't see for shit, and I had to be careful I didn't damage my frames. It was very silly.

How did the spectacle yank become a trope? #trope #tropes #TVTropes #Eyeglasses #spectacles

As I’ve been trying to adapt to wearing my glasses more. One thing I just learned.

I tend to cock my head a lot. Like a Labrador.

My glasses force me to keep my head level. Which is … weird.

Got up early to pick up new #eyeglasses, so decided to install new #LinuxMint. The actual OS is fine, but of course various programs in the Software Manager are changed.

For example, #KDEKate jumped from 21.12.3 to 23.8.5, and while colors can be set for the text editing area, menu bar and status bar don't seem to do #DarkMode any more, not even via Zoom Text toggle, which forced it in the version I used previously.

And though I'm using the same Deja Vu Sans Mono v2.37 font as before, it appears differently. Pics show the same line of icons in the old and new Kate versions. While the line of hearts is mostly the same (the gray heart no longer appears smaller), the colors of the hearts are mostly gone, and that of the squares are entirely gone. Other characters appear different, as well. Weird.

'Night vision lenses' could give you power to see in the dark using simple eyeglasses

I feel like I should either sit much closer to my computer monitor or much further away so that I won't have to take off my glasses. I still haven't really mastered the middle distances.
#Eyeglasses

Weird physics question just occurred to me…

If I'm looking in the mirror while wearing my bifocals, and I'm standing right in front of the mirror, inches away, but I'm looking at something a meter or more behind me in the reflection, should I be using the near distance part of the lens because I'm near the mirror, or the far distance part of the lens because the thing I'm looking at is far from the mirror?
#Physics #Eyeglasses #Optics #RandomThoughts

After a year or so, I guess I'm still figuring out bifocals (Progressives® actually). I still haven't mastered in-between distances. Is there a trick to it? They work great for things far away and for reading, but I just have to take them off altogether for in-between stuff like using my desktop computer.

Yay. My new glasses came. It was my first time ever ordering eyeglasses online.

Recycling tip: It looks like the primary collector of old eyeglasses in my are is the Lions Club. They have eyeglass donation boxes around the city. #recycling #glasses #eyeglasses #ConejoValley https://e-clubhouse.org/sites/conejo_valley/page-6.php
