Just this year march I got my 2nd pair of spec. The first one I used for years. I never do any research on getting specs what kind of lens , coating whatever. I just got a normal len. The first spec I wearing, I never know is lens coating wear off, I thought is lens " aging " so got those cloudy glare while i see in low light condition which is quite obvious.

So this year march I got my new spec which is 2nd one. I also never do research don't even know what coating. Is after just few month which july I discover why I see those cloudy glare again when under low light condition. Than this time I do a research what lens, what coating than discover is due to the coating on the lens wear off. Which cause those cloudy glare when I see things in low light condition those cloudy glare are obvious been seem while I wear my spec.

So my question is, come normal glasses lens the coating just last only few months? DO note. I never use any hash chemical or my t shirt whatever cloths to wipe the lens. I always just dry wipe the lens with the spec clothes provided. So I wonder By right I cannot dry wipe? Should risen with water than use the spec cloth to wipe the lens? But I see most people just use the spec cloth dry wipe the lens. So which one is more correct ways to wipe the lens?

I got attach the photo of my spec, is only the left lens the coating wear off.

" Update " Just today I went back to that spec shop and show them. They agreed to replace just the Left lens since the coating wear off only appear on left lens without any charges. I ask them is it under warranty for one year? They just claim yes. They told me at least one week or so come back take but my old spec is kinda more cloudy sometimes hard to see the wordings clear on the computer or phone, so I tell them can be faster? Than they told me they will check and claim possible might be this Friday. I shall see how the end result go "

Lens coatings should last several years of normal, careful use. For me though I do not order nor pay for any of the various coatings. I wash my glasses in the dishwasher (top rack of course) every so often and coating would be annihilated. But my glasses are very clean.

I don't know the spec shop will offer free service to fix my left lens coating. Which you see from the image I have posted. The left lens the middle part seem coating is wear off , the right lens still seem ok. I just got it this year march than last month July I discover why I see things under low light condition can see " cloudy glare " while I see my iphone or read some stuffs. If I don't bother it don't really affect my reading. I still can see clearly quite well reading from iphone or typing here current on the iMac. I heard some folks claim can be re coat if your lens never get scratch but some claim cannot need to get new lens.

I use both clear correctives, and polarized sun correctives (both polycarbonate).

The clears last indefinitely, and that's saying something as I work outside all day, and do wipe my glasses on my (sometimes dirty) shirt.

One thing I have noticed is that the polarized sunners are coated, and the coating wears incredibly fast; especially-so when continually exposed to full Sun.

I confronted asked the Opt about 'why', etc., and they insist that the coating is necessary, otherwise they wouldn't be sunners (part of me wanted to call bs, but I was in-need for an upcoming trip).

Opt recommended that I not set them on the dashboard, for ex, to increase the longevity.

My 2yo clears still appear brand-new.

I'm moving back to glass next year (I'm only l:20/45 & r:20/60, or something like that).

I do around google around etc. I noticed some claim the next spec they going to do will not want any coating on their lens and yes that is pure glass. But some folks claim if you always do work in front of your computer , look at phone or even drive at night. Will get affect on your eyesight. This is why most opt in coating along the plastic lens.

Next of course is weight as glass will add additional weight beside the type of frame you choose.

Both my wife and I (and my kids) wear glasses. Getting new ones is dependent on which one of us (my wife or me) has eyeglass coverage on our employee provided insurance at the time. So upgrades tend to be every 3 to 5 years, depending.

There was a pair I'd gotten several years back that had coatings and those coatings were doing exactly as what OP describes. But we were not in a position to get new glasses. It got to a point where I was trying to use old glasses just to see and do my job. But it wasn't working.

Eventually I figured out it was the coatings and with nothing to lose, I tried what the internet suggested (here and other places) and used Armour Etch on that old pair of glasses.

2024-08-04 06.44.27.jpg

Armour Etch is a hobbiest tool for making etching in glass. It's basically an acid in a creamy paste. And it can remove the coatings. You end up with clear glasses. It does not remove scratches though, so if there are scratches on your lenses you'll have to live with that.

But if your lenses are actually glass, do NOT use it! It only works for this purpose on acrylic/plastic lenses.

After this, I have purchased new glasses twice and I have made it EXPLICITLY clear to the business that I do not want coatings of any kind. Transitions is fine, because that isn't a coating so I get that. But the anti-scratch/anti-glare that they routinely push and apply. That's what I don't want.

I've been in front of a computer screen since 1980 when I was nine. I didn't start wearing glasses until I was around 25, although I should have been wearing them long before that as I have an astigmatism. I've had jobs since 1999 that require me to sit in front of monitors all day. Then I got home and sat in front of a monitor. Because I work from home now, I sit in front of a computer for 16+ hours day, My glasses have always been with non-coated acrylic lenses and I stopped using coatings around 2020.

Other than the fact that I am about to turn 54 and I am aging, I notice no difference here. Bifocals came in quite a while back. I'd say my eyes are quite adjusted to staring at computer screens by this point.

They should last, but in the past decade the coatings have gotten real cheap and the major eyeglass companies still push them. I stopped getting lens coatings about four years ago. I'll deal with any scratches because after a few years I won't be dealing with the coating coming off and making the lenses cloudy.

What you can do, rather than get actual 'sunglasses' with an Rx, is get a pair with a dark tinting. There was this two for one deal I took advantage of once and I did that. It's not a coating, so it doesn't wear off, but it's dark like sunglasses because that how they make the acrylic. The tint is part of the plastic. I still have that pair of 'sunglasses'.

They never push me on " coated plastic lens " I just told them get a normal lens when they ask me what type of lens I want. And yes as you see the image of my spec, the left lens coating in the middle wear off. I wil see " cloudy glare " if I read under low light condition. I can just ingore it ,thought as I still can see quite ok on the screen. While day time i look outside is ok, those cloudy glare don't appear so obviously but if I focus it will tend to see a bit. Seem like in future when I going to make new spec , get glass lens? or just plastic lens back without coating ?

So now you on plastic lens BUT without coating?

Since I started buying glasses the lenses have always been acrylic. I just stopped getting any coatings at all in 2020-2021. The glasses I am wearing right now are the second pair I've purchased without any coatings.

One of the main reasons I do NOT get glass lenses is because they would be too heavy and too thick.

Will get scratch easily your plastic lens since without coating? Surely some spec sales staff will say better get coating so your plastic lens will not get scratch or if you work a lot in front computer...

you first pair is due to " aging for years so you change now to 2nd pair ? "

this stuff my area never sell. I never see this before. Hmmm.... I wonder if I go back to the spec shop , guess they will remember me since this year march I bought it from them next they surely have my sales record. Maybe I tell them can remove the coating ? Since what I search around a lot claim once the coating on the lens wear off you can't do a re coat . Unless is a new lens.

Yes, they do scratch and I have some scratches currently. But, I would rather deal with scratches than cloudy, blurry lenses.

Hmm isn't scratches marks more like " irritating " than cloudy blurry lenses? Like I mention, I only that cloudy glare from my left lens if I see things , read under low light condition but come view on desktop PC or anything bright I will not say can see those cloudy glare.

That's you I suppose. Scratches don't bother me and I just look right through them.

Have you ever tried to see clearly through a dirty window? Can you even? I'm a graphic designer so I need to see things on my screens as clearly and sharply as possible. I make mistakes when my lenses are smudged or cloudy. A scratch, while annoying doesn't make things cloudy and my eyes just sort of skip over it. But it's hard to see clearly through clouded lenses.

For me at least.

Yeah; I have a few cheap drugstore sunnys.

But, I really need the Rx (not only for distant clarity, but also that my DL requires such).

Yes; the weight is a thing.

I'm near-sighted, but it's not really that bad . . . I just can't easily read the text on license plates, street signs, etc.

I just fell-into the trap of kotow'ing what I consider low-drag efforting on the part of Rx shops these days ("but, Sir: glass will break, it's exorbitantly expensive", et al.)

I was very nearsighted so I had high index lenses (so their thickness and weight remained reasonably). Because of the high index material they required anti-reflective (AR) coating. Typically the coating lasted as long as the glasses themselves (usually either the prescription changed of the frame wore out after 4-5 years).

But I did have 2 occasions where the coating was applied incorrectly and had to be replaced within a few months. One case coating started flaking off and in the other case, it turned milky white. In both cases the coating was applied incorrectly. I was able to return both pairs for a replacement.

That was my point though. The second pair of prescription eyeglasses with the darker tint that I got in the deal had my Rx.

At the time, that was America's Best offering the deal. Both prescription. Again, I just chose a darker tint on the second Rx pair.

I'm temporally bonded to my current Opt . . . laze of habit, I suppose.

But, when I get the Goods: Mein Gott!

Yah; I get the USD26 'Warranty' additive with each purchase, which helps if I have a near-now 'oops'.

Yeah, it was just a deal we happened into one time. They've run it since, but we go to a different store now.
