The new eyeglasses saga somewhat continues. Thought the third time would be the charm... seems like that doesn't ring true for this situation. [more inside]
This is a follow-up to a question I asked two weeks ago. There's still no resolution - replacement eyeglasses are just as bad. [more inside]
Maybe I'm just imagining this, but I seem to remember seeing an example of the word "Push" that when viewed upside down read as the word "Pull". My fever dream or a reality?

My dad's fed up with his Verizon cable + internet package. It's expensive, and they won't let him suspend it when he's not there for months at a time. He'd like to get his services from a less user-hostile service provider. Ah, but what kind? Cable? Satellite? Something over phone lines? [more inside]
This thread and this hypnotic diagram reminded me of a science fiction short story premised around the idea that breakthroughs in psychology and applied mathematics had made it possible to design two-dimensional black and white images that would produce extreme effects in anyone who looked at them. The result was a society in perpetual counter-terrorism lockdown. An image like "The Parrot" could cause immediate seizures and fatal strokes, and one terrorist sneaking a placard of it into the Superbowl could not only kill everyone in his immediate area but also viewers at home. Our main characters in the story are tweens who attend a school with translucent windows. They've gotten their hands on a low-powered nausea-inducing image and they've formed a secret club to take turns looking at it. Where can I find this story? [more inside]
I walked away from my last visit to the optometrist with a prescription for bifocals. All for the low low price of $20. The bruises on my ego were free. [more inside]

Problem: the only audio out connector my TV has is optical. How could I connect a set of 3.5mm or 1.8mm headphones to this port? [more inside]

I've just bought a second-hand Shuttle XPC computer with an Nvidia sound card. One fault is bugging me: no sound through the analogue audio outs or headphone sockets on the front or back, even when the operating system volumes are set to maximum. However, I have been told that the previous owner used the optical audio out. Is it possible that he could have disabled the analogue sound somehow? If so how might I re-enable it?
Glasses filter. I bought my frames at Lenscrafters, but had the prescription filled, and the lenses put in the frames, by a doctor in my hometown. The lenses are the progressive type. My doctor mailed the finished glasses back, and left the markings on the lenses which help with adjusting and fitting the lenses the first time. After the first time fitting you erase the markings with acetone. Can I trust Lenscrafters to fit and adjust these? [more inside]

When I look at an image (on my LCD computer screen) that is composed of a combination of solid colors separated by black borders, I perceive the colors as appearing on different planes of depth, as if the image were three-dimensional. If I close either eye, the illusion collapses. Am I the only one affected by this, or is it a consequence of the way LCDs display color? [more inside]
This may be an easy one (at least I hope so - and no, it hasn't been easy for me). Is there a site, or more than one site, that is somewhat devoted to compatibilities in hardware? I'm looking at notebook cdrw/dvd-rom (slim) drives and it would be nice to know which models will - ostensibly, anyway - work with which laptops. Help if you can. Thanks.
I'm about to buy a new pair of eyeglasses. For my prescription I want high index progressive lenses. I want the high index so the lenses will be as thin as possible. I keep hearing that Zeiss lenses are better than other brands and would like to know if this is true before I spend my money. Costco does not sell Zeiss. Is whatever Coscto sells as good optically?
