When outside, I wear Action Optics photochromatic prescription dark glasses with a 2.5 bifocal magnifier. I have a permanently dilated right eye courtesy of an injury 46 years ago, and a slight astigmatism due to age. The bifocal is low and out of the way, but great for tying on a small fly when fishing.

For sitting at the computer, I still need no optical aids at age 68.

I wear glasses outdoors (always while driving, sometimes when just walking around). My correction is relatively small (1-1.5 diopters) so I generally don't need them indoors, though I do have an annoying astigmatism (blue lights in particular are very smeared). My regular glasses are CR-39 plastic with an A/R coating, and I have a dedicated pair of (polarized) CR-39 sunglasses, I like that better than carrying just one photochromic pair. I can't stand polycarbonate as a lens material, the chromatic fringing drives me crazy.

I have a dedicated pair of glasses for stargazing and nighttime nature watching, these are crown glass with a slightly stronger prescription that allows me to focus just past infinity. They are a huge help for avoiding eyestrain at night and make things almost achingly clear, even compared with my regular lenses. Glass is still amazing stuff.

The far "in-focus" plane for me without glasses is just about at monitor distance. As presbyoptera continues to take hold and reduce my close-up vision (it has already started, much to my annoyance) I hope I'll still keep that far plane just about in clear focus. :)

I need/use standard reading glasses so I voted yes, though I don't wear glasses otherwise. To me there are three categories for glasses- always, reading only and never...

Since the 2nd grade. I had gotten so used to fuzz on the black board that it was a miracle when I got my first glasses. My parents thought tortoise-shell was nice..... Wore them until J. H/S and then got black. Now "aviators".

You are experiencing the chromatic aberration of the eye. Don't you know the wonderful story about that? Doubtless oversimplified, but: a) Newton believes that lenses must have chromatic aberration, so he invents the reflecting telescope thinking it is the only solution to the problem; b) Euler, I think, observes that the eye is obviously achromatic and therefore achromatic lenses must be possible, works out the math, and telescope makers start making crown/flint achromats. c) Only after achromatic lenses are developed and in wide use do people finally discover that the eye is not achromatic at all! Brain postprocessing.

I remember observing this in a dramatic way in high school chemistry when we did "bead tests." You're looking at a glowing loop of wire in a Bunsen burner, and you're looking through cobalt glass, which blocks out the sodium yellow but passes both the high and low ends of the spectrum. And by golly, the wire looks like a red line with a blue halo around it, and by doing something I was actually able to refocus my eye and see a blue line line with a red halo around it.

Hah! It started when you were a kid. Watch little kids. They'll hold things six inches away from their eyes because they can focus all the way down to that distance. Presbyopia is a continuous process, we just don't notice it until our close-focussing distance is farther than our comfortable reading distance. Age 40 for me.
interplanetjanet wrote:II have a dedicated pair of glasses for stargazing and nighttime nature watching, these are crown glass with a slightly stronger prescription that allows me to focus just past infinity.
Oh, thank goodness. I'm not the only one. That is always an issue for me, optometrists feel they are breaking the rules if they write the prescription for infinity instead of twenty feet. My optometrist does it, but under protest. Did you have to beg and plead?

My "hiking glasses" are prescription sunglasses that focus at infinity through the top part, and have a very small close-vision bifocal add at the bottom for peering at maps, camera settings, etc. Unfortunately I didn't get photochromic glasses--forget what the decision process was--so they are no good for naked-eye stargazing. Fortunately, my naked-eye vision is good enough to point my binoculars at whatever I really want to look at. And the all-too-rare experience of being able to look up and just see the Milky Way without having to look for it doesn't require infinity focus.

My "normal glasses" have a larger-than-normal reading section with the bifocal line higher than usual. The other day I saw a casual acquaintance who happens to be an optometrist, for the first time in years, and the first words out of his mouth is "Your bifocal line is too high." Sigh. I spend most of my visual life at a computer screen. Optometrists believe you should be doing that through the top half of your bifocals. That just plain doesn't work for me, something about the way my brain is wired, I can't read immersively unless the print is toward the bottom of my visual field. So I position my screen low, and my bifocal line is high... and my reading section is a compromise power, workable for both computer screens and books.

I found out I needed glasses when I went to take they eye test for my driver's license at age 16. Glasses and contacts ever since.

Now I need reading glasses, but usually go without when I'm not wearing contacts. Optometrist used monovision (two different power contacts) to allow for reading. It worked for a while but I think my vision has already changed.

Because of environment and genetics in a generation or two everyone will need vision correction.

It is rare and even difficult to get prescription lens made of glass. Now that most of us have plastic lenses, when will the term "glasses" change? What will it change to?

I've got a very strong -8.5 and -8.75 prescription and had never been able to tolerate anything but CR-39. The problem with all the thinner materials is the thinner they are, generally the lower the abbe value is, which means that the chromatic aberration is worse. Then the stronger your prescription the more aberration there is as well.

I'm amazed at the marketing or whatever that puts people with mild prescriptions like yours, where the CR-39 lenses are not going to be that thick anyway, into optically inferior materials like poly. My wife has a +2 or so prescription and all she did was ask for CR-39 and scratch resistant coating at the big chain, and the "optician" asks if she wants just regular scratch resistant or the super-de-duper scratch resistant for just a little more. So she says I'll take the super-de-duper. This place has their preset packages, where you can't get coating B with lens material A and what not, so this scratch resistant choice was used to switch her from CR-39 to poly without telling her this. So then the glasses were intolerable and returned for a refund within a week.

However, with my latest glasses, I was convinced to give Trivex a try, this is not the thinnest, but is the lightest material. This has abbe value of 44 vs. 58 for CR-39 and 30 for poly and similar low values for most high or mid index materials. The other advantage for people with strong negative prescriptions, like mine, is they can make the center thickness 1 mm with Trivex vs. 2 mm with CR-39 and other materials, thinner center means thinner edge. For the first time, I am happy with something other than CR-39.

I've been nearsighted most of my life, and have always worn glasses for distance. Reading, not a problem. It was always annoying when I had my glasses on and then needed to read something quickly. My distance prescription doesn't work for reading, so I'd have to lift my glasses to do the reading.

So, my optometrist suggested progressives. That solved the reading problem, but I hated what they did for my distance vision. Given that my biggest need for glasses is for distance, I didn't like that the field of vision for distance was much smaller. The edges of the lenses were useless, especially for driving, when I'm always looking out of the corner of my eye. Turning my head to look directly at the object was simply annoying. I wonder if a plain old bifocal is worth a try...

Another problem I have is that the computer monitor text is getting a little blurry out of my left eye, but not my right. I'm a programmer, so I spend most of the day looking at it. I guess my right eye is compensating, but I'm starting to wonder if I need an extra pair of glasses specifically for reading something that is two feet away.

There are many designs of progressive lenses, I am in my first pair and have no problem with the distance part. The reading area, otoh, is very narrow, but I am getting used to it. I opted for expensive "free-form" lenses as these are supposed to be easiest to adapt to. I plan to try a regular lined bifocal next time and see if I prefer the larger reading area.

That said, I not choose to wear progressives (or lined bifocals, though I have never tried them), if I did not have to. Until I got older I could read with my glasses on (I can also read without them but only if the material is about 3 inches from my eyes), as I got older I discovered I could read by sliding the glasses down my nose. This allowed me to delay getting progressives/bifocals for several years, until I recently started running out of nose.

I also have a pair of single vision glasses for the computer, these are weaker than I need for distance but I can walk around the office with them and see clearly enough, stuff that is more than 7-8 feet away gets blurry. These also are usable for reading, particularly if I slide them down my nose a bit.

Very, very strong prescription.

I was wearing disposable contact lenses until I ran out in September, then decided to wait until January to get new ones so I could pay with my 2012 Flexible Spending Account, then got so used to glasses that I'm in no rush now that it's January.

Yes! It's crazy - the last priority of opticians while choosing lens materials often appears to be optical quality. What's kind of "funny" is that poly actually scratches much more easily than CR-39, even with a coating - it is more *impact* resistant, but flexes and deforms more easily and develops scratches through very minor contact. The arguments I have to have to get my kids CR-39 instead of poly are just silly - none of them play sports where they're likely to benefit at all from the impact properties of poly, but they live rugged lives and lenses that scratch won't last.
However, with my latest glasses, I was convinced to give Trivex a try, this is not the thinnest, but is the lightest material. This has abbe value of 44 vs. 58 for CR-39 and 30 for poly and similar low values for most high or mid index materials.

For the first time, I am happy with something other than CR-39.
My mom's latest lenses are Trivex and she's very happy with them. I think it's a good compromise material. High-index glass can be ground to 1mm too, though there have been some concerns about liability in the USA (of course).

Spectacles?

I've not had a problem getting glass lenses. If your optician uses VSP labs, they can accomodate a variety of glass orders and the quality seems quite high. I don't know about most people, but the difference is still quite noticeable to me - CR-39 is definitely clearly than poly, and glass is another step clearer and sharper than CR-39 (but heavier!).

Ha, yes. I know what you're talking about, but I can clearly see my astigmatism across the spectrum when looking at something glowing across a room (LEDs seem to be the worst at this, actually), showing up as doubled "SW/NE" images, worst in my left eye. Blue light is smeared more in general but in the direction of my astigmatism it's *really* bad - my DirecTV reciever has a little blue circle that lights up when it's on. If I look at it in a dark room with just my left eye, it's a pair of rings, with just about the same separation as the olympic rings (just barely linked). Oy.

Yes, I started noticing it when I realized what was happening at about age 15 (shaving my armpits and not being able to focus on the razor head :roll:). Just for grins, I asked my 13yo daughter to read one of the microprint lines on a check this last weekend (a 5 cent Vanguard dividend check, as it turns out). She could focus well at 2-3". My current closest in-focus plane (at 36) is more like 5-6". I'm hoping that as prebyopia continues I end up with an in-focus plane somewhere around 20-24" and I'll get to mostly dodge the need for readers. :)

Yes! I need to do so again with my current optometrist, actually (my Rx has actually gotten slightly weaker over the last two years). They're just plain glass with an A/R coating and I'm amazed at how well the coatings hold up when bonded to glass. I'm careful with my glasses but the coatings usually start to wear or flake after a year or two no matter what, these look the same as the day they were made.

From what I've read glass, in general, is still common in Europe. I don't think I'd like the weight of glass, though.

I don't know how it would hold up for kids, but the newer (and costly) AR coatings, like crizal, teflon, etc. supposedly have scratch resistance near that of glass. I want the AR coating anyway, and I've been happy with added bonus of the excellent scratch resistance.

It does weigh more, but it's very manageable for someone like me with a low power prescription. Supposedly Lantal and similar have such a high index of refraction relative to their density that they can actually be lighter than plastics for the same Rx, but that high IR comes with a lower Abbe number than undoped glass. Everything is a compromise.

I do love the scratch resistance of glass. I could polish an old set of glass glasses I had (with A/R coating) with my t-shirt and never even ding the coating. Which brings us to...
I don't know how it would hold up for kids, but the newer (and costly) AR coatings, like crizal, teflon, etc. supposedly have scratch resistance near that of glass. I want the AR coating anyway, and I've been happy with added bonus of the excellent scratch resistance.
A friend of mine is an optical engineer, and he put it to me like this:

A large part of what makes a coating hold up comes down to the characteristics of the material it's bonded to. Imagine your A/R coating is like a sheet of paper towel. Hold it against a piece of something hard (like glass) and something soft like a pillow and poke gently at it from random directions - the sheet against the hard surface is much harder to make a hole in. Other things being equal, a coating on a material with less flex will outlast ones on material with more flex.

He went on to talk about how some of the composite coatings they make now basically underlay the A/R layer itself with some kind of intermediary that helps to make the transition less abrupt, and hopefully makes them last longer.

My 11yo daughter is the only child of mine who wears glasses full time, but she's incredibly rough on them. I had hers made of CR-39, uncoated, and that seems to hold up against everything she can throw at them for at least a year at a time.

My computer/most-of-the-time bifocals are similarly configured. Thought I was the only one. Had the darnedest time convincing my eye doctor and the eyeglass store people that I really, truly wanted the "computer" portion at the bottom of the bifocals and explaining why. I find having intermediate-distance focusing at the bottom of the glasses convenient for other activities like using a sewing machine. Handy too for seeing the car's dashboard; otherwise everything's a blur.

I have another pair of bifocals just for reading books.

I've worn cat-eye glasses thick-as-Coke-bottle-bottoms since I was seven. Don't know how that happened. Neither of my parents wore glasses until late middle-age.
