> They are so cheap there is no reason not to do it this way.

Besides the environmental cost, maybe.

Relative to other things like travel, commuting, home energy usage, electronics, etc, I'm guessing the environmental cost of a pair of glasses is very, very low.

It is important to focus on effective actions. For example, a lot of people think that somehow recycling affects climate change, which (AFAIK) is not true in any meaningful sense. That isn't to say one shouldn't recycle -- there are plenty of reasons to do so in many cases.

I think the broader point was that buying something only because it's cheap is generating unnecessary waste.

I'm not saying this is the case here because the original pair of glasses can still be used, but isn't avoiding this kind of behaviour a good thing?

I believe that recycling aluminum takes significantly less energy than smelting it in the first place.

I don't have any idea about plastics/papers.

Post-consumer paper can be recycled in to some forms of low-density card that doesn't require high quality pulp. Egg cartons come to mind, and as a percentage in some packaging, newsprint and sanitary papers. Post-consumer paper cannot easily be recycled in to anything resembling printer paper due to the contaminants. Pre-consumer paper is recycled heavily as it's of known quality.

I'm not aware of any plastics that are recycled in to the same form. I know that PET (1) and HDPE (2) are recycled in to fibres.

It's a similar story to glass, certainly where I live a large amount of glass is recycled in to crushed aggregate rather than new bottles. The energy costs of cleaning don't make it worthwhile.

Glass bottles used to be reused, which is the responsible thing to do.

Consumers didn’t like it because scratches accumulate on the outside of the bottles.

I always thought it was a shame that we stopped doing that, but plastic has taken over pretty much for all the glass bottles that used to be recycled.

Aluminum is the only part of recycle that is really profitable. That's way people picking through trash take the cans and nothing else.

Everyone I've seen do this takes bottles too, and it's because they can redeem the bottles and cans to collect a state-mandated deposit.

Plus you can probably donate the glasses. There is probably some poor person out there with a prescription close to yours.

It helps the amount of garbage put into the environment, which is good regardless.

I don't throw away my old glasses. I keep them in various places as backups, such as in car gloveboxes, in the home emergency kit, in a bag while traveling and so on.

When I was younger I used to tease my Mom & Dad for essentially treating their reading glasses like pens or pencils, and letting them diffuse around the house as the acquired new pairs.

Now that I'm in my mid-40's, I take it all back. Having a pair, even if it isn't the exact right one, always with reach is a godsend.

When I wear my contacts, I need reading glasses. I buy them essentially in bulk from Amazon and leave them scattered everywhere.

Me too. I have around 10 pairs, so I never find myself in a room/place without them. I like Dr. Dean Edell’s for their combination of style/comfort/build quality/light weight. $9.99/pair

Me too. Even though my eyesight continues to deteriorate, a pair of old prescription glasses is many times better than no glasses at all in an emergency!
