Mine have built a decent number of very small scratches and they're getting annoying so I'd like to get rid if at all possible.

I've seen various things suggested including:

  • lens scratch repair kit (reviews don't look great on amazon)
  • baking soda paste
  • non-abrasive toothpaste
  • furniture polish (temporarily fills in the scratch from what I can tell)

I'm reluctant to try any of them without some first hand accounts. No lens coating on these so no worries there.

Thank you in advance!

edit: I just want to say thanks very much to everyone. I ended up getting my prescription emailed to me and buying a new pair for €17 (about $19 USD) delivered on a site that one helpful poster linked. Looks like they will take about 3 weeks to get here so I'll put up with the scratchy ones until they get here.

When they do arrive I will take some pictures and test the various methods I found online then post up what works and what wrecks the lenses.

Afaik you would destroy the coating on modern lenses, making it worse. That's why I am intensely careful with mine, I only carefully wash them under warm water (not hot) with dish soap without additives, and then use a microfibre cloth to dry. Water and dish soap first to remove anything that could scratch, even microscopic stuff.

After around 4 years of this, mine are almost as good as new still.

[-] khannie@lemmy.world 10 points 7 months ago

Ah unfortunately they've taken a bit of abuse over the years. Nothing major so the scratches are really tiny but enough of them have built up from rough and tumble with the kids etc. that they're a constant annoyance now. :(

I do actually do the dishsoap / warm water thing myself and find it great.

These were my backup pair on a 2 for 1 offer so I didn't get any lens coating / thinner lens thing on them.

Could a local optician sort it?

[-] khannie@lemmy.world 14 points 7 months ago* (last edited 7 months ago)

You know, this is so blindingly obvious I never thought of it. Haha! Great idea.

edit: I actually can't believe I didn't think of this. Chuckling away to myself here.

edit 2: I looked up the opticians I bought from and they have a page about scratches that says they can't unfortunately. :( It recommends new lenses. Not sure if that's profit motive or not though.

[-] Zorsith 17 points 7 months ago

Polishing is how the lenses are shaped into your prescription; buffing out scratches would change the shape of the lens

[-] qprimed@lemmy.ml 10 points 7 months ago

my undaeratanding is that lens material is so optically tuned for weight that removal of any amount of material makes a difference to the focusing - not to mention the possible coatings on the lens. this is what I have been told, I have no other evidence.

[-] ABCDE@lemmy.world 6 points 7 months ago

blindingly obvious

Perfect.

[-] MrQuallzin@lemmy.world 3 points 7 months ago

Costco's optometrist said they couldn't buff out the scratches on mine since they don't actually use glass anymore. They use polycarbonate lenses which are strong and won't shatter if broken (I've definitely tested this on accident...)

Last time I bought glasses there, it cost me ~60$ for 2 pairs. Both with scratch resistant coatings, and one with a photochromic coating (auto tint in sunlight).

[-] khannie@lemmy.world 2 points 7 months ago* (last edited 7 months ago)

Thanks. Just had a look and that is incredibly cheap. They also do ~~free~~ standard shipping to my country so I will seriously consider this.

[-] UnpledgedCatnapTipper 3 points 7 months ago

Zenni optical is another affordable online option! Or eye buy direct. I've only used Zenni, but all of my glasses since like 2011 have come from them and I've had 0 issues!

[-] khannie@lemmy.world 3 points 7 months ago

Ah! I knew there was a place someone had mentioned to me before that they were happy with and couldn't remember the name. It was Zenni. I ended up buying from that site linked above for very cheap and I'm going to do some experimenting with these scratched ones when the new ones get here.

[-] khannie@lemmy.world 2 points 7 months ago* (last edited 7 months ago)

Just wanted to come back and say thanks. I emailed my optician for my prescription and bought a pair of glasses off this site for €17 delivered (about $19 USD). Do you mind me asking how long yours took to arrive? I'm in one of the "standard delivery" countries.

[-] Darkassassin07@lemmy.ca 2 points 7 months ago

If I remember right, it was just over 2 weeks; but it's been a couple years since I ordered.

I've ordered my last 2 sets from there, and had at least 3 family members ordering from there too. We've never had any issues aside from one poorly fitting set, which they returned and got fresh ones free of charge. I really couldn't be happier with goggles4u.

I've really got to get around to seeing the optometrist and getting a fresh prescription... Time flies.

[-] khannie@lemmy.world 2 points 7 months ago

You will not believe this but when I emailed for my prescription earlier I was told I'm well overdue (2021 was my last test) and I said "time flies". She took the time to write "OUT OF DATE" twice on the scan.

Thanks for the timeline.

[-] zephorah@lemm.ee 5 points 7 months ago* (last edited 7 months ago)

You pay more initially, and have to look around more for it, but glass lenses hold up. Drop them. Stick them in your pocket with your car keys and pens. Clean them with whatever. Lose the case on day one. And they stay scratch free. For years.

Granted, this is only tenable if you have a “lighter” prescription.

I remove mine for close up stuff and thus my prescription has remained the same for over 20 years. I get new glasses not because the lenses scratch up, but because the frames break. I average new glasses every 8-10yrs.

Glass lenses.

[-] Cenotaph@mander.xyz 3 points 7 months ago

Quality plastic lenses can last that long. Often being able to keep glasses that long depends most on the stability of your prescription, and not going for bottom of the barrel coatings.

Glass lenses are harder to scratch, but are heavier for the same prescription and if you get hit in the face can shatter into shards that are quite damaging to the eyes.

If getting hit in the face is not a risk for you and you dont mind the extra weight go for it, but it's worth noting there are some downsides as well.

[-] zephorah@lemm.ee 1 points 7 months ago

That’s why I said it depends on how light your prescription is. The husband has coke bottle lenses and cannot do glass. But he has to use the case. He has to use a special cloth to clean the lenses. He has to check against cleaning chemicals. He has to be very careful or they scratch, doesn’t matter what “special coating” is there. Those lenses do scratch up.

I’m less than -2 in both eyes so the weight doesn’t matter so much for me. I drop mine on the (bacterial lava) floor of a patient care area and I can grab whatever industrial, don’t use bare hands, wipe is available to purge the lenses of bacterial and viral load. And then stick them loose in a pocket with keys, pens, loose change, scissors, and they come out after a couple hours of that scratch free.

I get hit in the face. For decades. And decades of dropping them on concrete and everywhere else. No issues, breaks, or scratches thus far.

What are the stats on that? Are they a reality for the curved milled glass lens? Or is it a falsehood used to sell planned obsolescence lenses?

[-] ramenshaman@lemmy.world 3 points 7 months ago

I've never even been offered glass lenses. I thought they were phased out so that people would never get broken glass in their eyes.

[-] zephorah@lemm.ee 2 points 7 months ago

I’m been smacked in the face and dropped them multiple times on concrete, industrial linoleum tile, and hardwoods. Never even seen a crack. I’m sure there are things that can do so, like an airbag exploding in your face, but I can’t imagine shattered broken milled plastic not being dangerous as well.

You have to ask for glass. They bury it in favor of the garbage that scratches up over time.

[-] theskyisfalling@lemmy.dbzer0.com 5 points 7 months ago

Stuff like toothpaste is way too coarse for things like this. It isn't something I have tried as I don't wear glasses but have you considered trying something like a rubbing compound used during paintwork on cars etc?

It is basically a fine grade liquid sandpaper and is used to buff up the final laquer coat to a good shine.

Pretty sure you can get different grit levels and may require some elbow grease but may be an option worth looking at?

[-] irotsoma@lemmy.world 2 points 7 months ago

You'd need to be able to replace the coatings on them. The scratch would likely be the easier part. The coatings might be hard to get. Most sold commercially are not as permanent and industrial ones are either very proprietary or require expensive equipment that wouldn't be worth it for a one pair of lenses.

[-] Kaiyoto@lemmy.world 2 points 7 months ago

I don't think it would work in the slightest either way but rather than buff them out, maybe find something to fill in the scratches.

[-] khannie@lemmy.world 1 points 7 months ago

Yeah one of the recommended things I saw was furniture polish or car wax to fill them in. Both would only be temporary. Based on the replies so far I may give this a whirl as I don't see it being damaging.

[-] credo@lemmy.world 2 points 7 months ago

I don’t know about outer coatings, but I always wondered if lapping film would work on glass lenses. Think super fine sandpaper for fiber optic cables.

[-] billwashere@lemmy.world 2 points 7 months ago

I tried it once. It didn’t go well

[-] thirteene@lemmy.world 2 points 7 months ago

After you get your replacement lens, you can also try putting a drop of resin and wiping it away. In theory the resin should fill the crack with a transparent material and the heal the blemish. Then you "buff it" by removing excess liquid before it cures. But as others mentioned there is coating and more specifically glass treatment that may cause issues, but that's the process for auto class repair (they usually drill out a hole around it first to prevent further spreading but that sounds worse here). Those kits can be pretty cheap

Don't have a solution, want to leave this here for the advice
