Staring at something in the same narrow focal plane for hours a day isn't as good for still-growing eyes as going outside and playing with a ball or something that moves and must be tracked in 3D. Your mom tossing you in the yard to play was doing you a favor.

Anecdotally, I do remember that when I switched from CRT to LCD there was a notable change in eye strain, but it may have indeed been due to adapting to viewing distances over time.

When electrons get stopped suddenly they lose that energy in photons of x-ray frequency, in other words your screen gives off x-rays. I've not heard of long exposure affecting anyone though.

Out of all my siblings (four) and family (mother, father, uncles, aunties, cousins etc) I'm the only one who wears glasses. Guess who spent the most of their childhood playing videogames and computers.

I'd be very surprised if it ended up being non-hereditary. Practically everyone on my mother's side of the family is nearsighted, and none of them really do anything directly in front of a TV or monitor for any amount of time. My sister and I are only a few years apart--I spent my childhood loving around in front of early-rear end CRTs and she didn't, but our eyes are equally bad. Wow, doc, myopia and astigmatism? You shouldn't have!

An interesting thing to note is for color* CRTs that there isn't much lead in the "panel glass" at the front of the display---that glass contains a few percent of lead oxide or barium oxide (and strontium oxide maybe?). The glass in the funnel and neck of the CRT, however, had up to 25% lead oxide, and all the parts were fused together with glass solder that has like 75% lead. I'm not sure why lower lead content glass was used in the front panel, to be honest. I do know that optical properties were a big factor--they needed a glass with a good index of refraction and dispersion that didn't discolor with age (due to electron bombardment). Lead and barium are still used for certain optical glasses. Also, cost and manufacturing concerns are probably another reason. Finally, the glass in the front panel is probably thicker. *Monochrome CRTs were made from a single piece of glass, I believe

This may be more marketing than technology, but I think it fits with the theme of the thread. Ever heard of a car being referred to as a "chick car"? When you hear this, you probably think of a Volkswagen New Beetle, Fiat 500, minivan or Back in the mid-1950s, Chrysler actually designed and built a car targeted specifically at women. It came with pink or light grey paint, tapestry-like upholstery, and a matching purse with coordinated hairbrush, wallet, change purse, cigarette case and lighter that sat in a special holder. The clasp was a large medallion that could have the owner's name engraved into it. This is the Dodge La Femme. It was just a Dodge Custom Royal Lancer with special trim, so it cost Chrysler Corporation little extra to make it. It was also sold as a "his-and-hers" type deal, where he would have a Custom Royal Lancer, and she could have a car that matched. It turned out to be a total flop. It only lasted for the 1955 and 1956 model years, and less than 2500 were sold across both. As it turned out, women who didn't care about cars wouldn't be lured by a pink one with a matching purse, and women that did care about cars weren't swayed by Dodge's marketing department. The typical women's car of that era was the station wagon, to haul around groceries and kids, especially in the rear-facing third row seat. Sunshine89 has a new favorite as of 17:24 on Mar 31, 2014 |

When I was a kid I would sneak into the basement of our local arena where there was a sports bar. In the bar they had a projection TV that appeared to be a regular crt facing a mirror reflecting the image up onto a projection screen. The whole unit was pretty compact with the TV directly under the screen and the mirror about a foot in front and it was all a single unit, not some Jerry rigged setup. Does anyone else know what I'm talking about? This was late 80s-very early 90s

We're already seeing places with deep pile carpet, wood panelling has to come back into fashion sometime. Yeah even brass bathroom and kitchen fixtures are coming back. If you watch HGTV/house hunters for long enough you see the styles rotating. I predict in about three years everyone will be going "ewwww granite countertops, that's a deal breaker." My 1975 condo has stucco on the ceiling AND walls in the common areas and it's got asbestos in it so it ain't going anywhere. Can't wait til people stop the anti-popcorn ceiling propaganda.

Mr Gatti's pizza had these. They were behind a waist high wall/bar and they intrigued my child mind. I desired to dance and play before the colored bulbs. Perhaps they would even transport me into the realm of the Nicktoons.

They're pretty rare today. Chrysler used to have a luxury brand called the Imperial which was marketed as a competitor to Cadillac and Lincoln. They were stately luxury cars of the sort that bankers and captains of industry would buy. In 1971 they briefly offered a burgundy vinyl top option with a subtle paisley pattern meant to imitate antique furniture. After some time exposed to the outdoors the burgundy vinyl would fade and the pattern would become very unsubtle, forcing Chrysler to replace them with plain tops for free. It has been speculated that Chrysler tried to use up unsold Mod Top material by redyeing it, but the stylist who worked on it has denied this. http://www.imperialclub.com/YearByYear/1971/Paisley/index.htm

I'm trying to find evidence of this, and I can't, but I'm sure I tried it at least once. I could have sworn in the late 90s Yahoo had some short-lived automated telephone e-mail checking thing that you were assigned a numeric ID code and a pass code and you could dial an 800 number and I think it would 'read' new e-mails to you over the phone or tell you if you had new emails waiting.

Now that's a whole bucket of obsolete.
