Scratches On Spectacles Lenses
Discussion
Impossible to remove scratches .
I don’t know how mass produced single vision lenses are knocked out but I do know that bifocals, varifocals and non-standard single vision lenses are produced.
The curves of the lens are cut on a precise machine and then the lens is smoothed and polished in a machine under pressure in a tool which has previously been cut to the curve required to achieve the power of the lens. They run in various grades of slurry until the lens is finished to the clarity that you would require from a spectacle lens.
If any scratches are found after this the lens will be binned and the process begins again. In theory it would be possible to put Doofus’s lens through the smoothing/ polishing process again but no prescription house would do it as the machines are designed to work with large (65mm and above) uncut lenses and the lens would probably break causing the machine to be closed down an£ the slurry discarded.
Trying to polish the lens yourself will merely blur the lens and your vision, so, as I said, impossible to remove scratches.
Ps the clue is in the name.

Plastic lenses. Is it possible to DIY scratch removal, or will I f
k up the prescription?
Scratches are only minor and caused by carelessly putting glasses down, lenses first, on desk and by, once or twice, dropping them on the ground.
Replacement lenses can be had around these parts for £38 apparently.k up the prescription?Scratches are only minor and caused by carelessly putting glasses down, lenses first, on desk and by, once or twice, dropping them on the ground.

My frames are Rayban, on their 3rd set of lenses, we have a shop called Spectacle maker, I take a prescription in, show them the frames, a week later I go in, drop off the specs, get a cup of tea, hour later pick them up.
No need for new frames.
Cool, thanks. I'll begin making enquiries.No need for new frames.
There are lots of cheap prescription glasses being flogged now (glasses2you etc) and although they are cheap the lenses don't last. Fine for standard prescriptions bad bad for strong + or - and 1.74 super thin lenses.
From a proper optician using quality lenses (Hoya, Esselsior etc) just the lenses are £600+ and will last for years. Online, less than £200 for the whole lot but they are st!
I envy people who can buy £30 prescription glasses!

Although scratch resistant coatings are better now than before lenses won't "last for years".From a proper optician using quality lenses (Hoya, Esselsior etc) just the lenses are £600+ and will last for years. Online, less than £200 for the whole lot but they are s

You could buy your specs today and scratch them to the point of uselessness in seconds.
It's all to do with care and luck.
If you put them on in the morning , take them off at night and don't put them in your pocket with your keys and change etc they will last the life of the prescription which generally is anything between a few months and a few years. That depends entirely on the way your eyes age or change for some other reason.
My mantra was always " on your face or in the case" and clean them with clear liquid hand soap and lukewarm water, dry with a CLEAN soft cloth or good quality tissue.
Don't clean them while they're dry and lens cleaning sprays are like polishing your car before you wash it. You'll just stick the dirt to the lens and rub it in.
I'm afraid, Doofus, you're stuck. If you can't tolerate the scratches, you are looking at new lenses. It's ridiculous people saying £4.00 or £38 or even £400 , they have no idea what your glasses are like.
BTW, it's Essilor.
We always used Hoya and definitely not Zeiss. When it comes to varifocals, do not be misled, they're all fantastic, comfortable lenses these days but they aren't better for having a name you know.

Well duh, you could drop them down a drain when you walk out the optician that does not mean it is a general rule.
I have been wearing glasses since I was 4yo, I am in my 50s now. I am well aware of how to clean glasses and by the way never ever clean with tissues, that is really bad idea. In all that time I have never "scratched them within seconds" to the point of being useless, even as a teenager. You seem to be talking hyperbole to make your point.
Glasses can and do last for years without being useless, especially the older glass lenses. The only reason one should change is if the prescription changes. I have a pair of wrap around Oakley prescription sunglasses that are now 20 years old and apart from one small chip on the lenses and the frames delaminating they are perfectly fine for exercise, although the prescription is off. Pay peanuts and you get low quality lenses.
You sound like an optician peddling their own products...
Never buy or get advice from an optician who does not wear glasses.
Scratches on plastic can be improved if they are light, there are a number of possible products.
Meguiars make a plastic polish, I use an old formula called Plast RX, works on phone screens and plastic headlights also, brilliant product
You can buy Micromesh sheets to polish out scratches.
If you don't want to buy anything try toothpaste on a microfibre cloth, don't rub in circles, just straight lines.
If you have some car polish (not car wax) try that, especially Autoglym SRP, another excellent product.
If they are just standard reading glasses then it is difficult to justify much in .the way of expenditure when you can buy replacements at £10 for 5 pairs from Amazon.
Get into the habit of not putting your glasses down resting on the lenses.

The glasses I am wearing now are five years old, used all day every day and don’t have a single scratch on them.You could buy your specs today and scratch them to the point of uselessness in seconds.

Just carry the little fabric bag/case in my pocket with my sunnies in and swap them over when needed.
No drama, and lenses can definitely last years.
I do have a feeling my upcoming eye test will show a change in prescription this time and hopefully the next pair will last a similar amount of time. These were about £700 as I recall.

I think a lot of what you are saying is correct with the caveat that for glasses you are most likely to have scratched a coating rather than the lens itself so you'd have to get to a position where all the coating is removed. I think it would be pretty hard to do a good job as the quality of finish is far more critical than on a screen or headlightMeguiars make a plastic polish, I use an old formula called Plast RX, works on phone screens and plastic headlights also, brilliant product
