Hi,
I presume you're referring to camera lenses specifically, as I don't think
binoculars* really ever become obsolete.
As far as camera lenses being built to last, I'd think a major factor for that is pride of workmanship and pride in the product your company produces, as well as the company's reputation, which all used to be as, if not sometimes more, important than profit. This is something that IMHO is very lacking, if not totally non-existent nowadays.
A lens built to close tolerances, and of quality materials, is generally more rugged/durable and won't get whacked out of alignment, nor rendered inoperable, with the slightest bump, and be able to tolerate temperature variations without jamming etc. Before the whole global economy, consumerism, the Internet, Wal-mart-ification of everything, etc., word-of-mouth and user experiences were very important to manufacturers, now, it seems not so much, as there are so many "manufacturers" and products, and so many people buying this stuff, that it seems to not matter as much, at least on consumer items(look at all the items sold on amazon with hundreds or even thousands of one and two star reviews, yet folks keep buying and then leaving more one and two star reviews)
.
I'm sure the pro stuff; cameras $5-10,000+ and lenses $2-3,000+ is still very high quality and built to last, since they likely make a lot more profit on those, and reputation is still somewhat important at those levels.
I also suppose that since the advent of auto-focus lenses, as well as the now generally adopted practice of planned-obsolescence, this idea of lenses being "built to last" is going the way of the dinosaur. What with manufacturer's being primarily ,or even exclusively, profit-driven, intentionally changing mounts/designs to force everyone to buy whole new systems every few years, as well as new innovations in motors, electronics, etc., I wouldn't expect any consumer level lenses, nor cameras to ever be built to last anymore(remember small appliances you could actually repair?).
*I have several binoculars that are many decades old, and as long as people have two eyes, spaced approximately 55-70mm apart, they'll keep working unless they are damaged. Mine all still work great.
