I have found a great reduction in eyestrain since changing to an LCD display from CRT. Couldn't manage half an hour before....no limit now. I'm 50 yrs with bi focals.....could *really* do with trifocals.....
Anyone know where to get trifocals on the net?

Personally I find LCD far superior to CRT but this has been covered a lot already, as have the various options on refresh rates and resolutions.
My one comment is that no-one has mentioned the anti-reflective coating available for glasses. I have this added to all my glasses and find that it makes a big difference. I use a monitor all day (LCD for the reasons already stated) but the anti-reflection coating makes a difference for everyting else too.
Incidentally the 'Peril-sensitive' coatings (called Reactions in specsavers or Reactalite in some other places) does not work in the car as they work on UV exposure. The glass in the car filters out most of the UV so the coating dosn't react!

Try your normal optician - he/she knows you and will hopefully be the most helpful.
I had this on my last close-distance and driving glasses, but gave it away in the end as it seems to have a cleaning problem. I could never get my glasses 'clean' without a strong detergent wash. I have gone back to plain glass and find it better, with no cleaning problems, I just use tissue and occasionally some meths.
Worse if you have aircon and the winsdscreen has the reflective coating as well!

I had big problems with coatings from V*****E****** going cloudy, may have been unlucky but they won't get my custom again for other reasons. I always have my specs hard coated & sometimes anti-reflective also, they do tend to get 'smeary' but not too hard to clean in my experience. I always have plastic lenses these days, & they really do need the hard coating - glass is a bit more forgiving provided you don't use them as grinding goggles
It's not a coating, it's some weird chemical in the body of the lens AFAIK.
?? sorry Peter, don't understand that - please explain
Thanks to all for their comments, I've just ordered a Samsung 19" TFT monitor & hope results will be favourable.

You can cure the aircon by plugging all the holes and I don't think they do reflective coatings on split screens

It varies from manufacturer to manufacturer - some of the coatings seem to attract oils from the skin more than others. The varifocals I bought have Nikon lenses & their coatings seem much easier to clean. Shame the varifocals are crap though ;-)

Longish term experience .........
I have been wearing glass photochromic (photochromatic?) lenses since
1973, and had tri-focal lenses in this media since 1992. May be I have been fortunate, but I have not experienced any of the problems that others seem to have had.The tri-focals (reading, a couple of feet away for screen, and distance) work well. So far as driving is concerned, the middle band gives good focus on the instruments. I have never experienced any problem with the lenses failing to react correctly in the car.
Tri-focals have the advantage over vari-focals in that they do not give the impression of tapering objects of which I have heard some users complain. I still have my 'riggers eye'.
I did have one pair with anti-reflective coating but found that this deteriorated after a while, probably due to my poor care! My current specs do not have this surface treatment, and I have not missed it.
Cleaning has been mentioned; I find that a quick wash under a warm tap, with a drop of washing up fluid, gives crystal clear lenses.
For the record, and in view of the original question, I have a six year old 19" 75Hz Sony CRT screen. No eye strain, and I use it a lot.

It arrived this afternoon, only took 4 days for ParcelFarce to get it less than 20 miles from their Liverpool depot to here. I got seriously p*ssed off with Parcelfarce, it is next to impossible to get to talk to a human now. They want you to do everything via their website, they proclaim 'real time tracking' etc. That's great until the driver carries your parcel around in his van for 3 days because he's an agency driver & hasn't a clue how to find you, & hasn't the gumption to be bothered to find out. All the tracking then shows is the time it was checked out of their depot into the van. They swore blind someone had tried to deliver on Tuesday, I know for a fact they never came near the place. They have one national number, I spent 20 minutes on it on 2 occasions before I could reach a human to talk to. After the first occasion, I got put through to the Liverpool depot, they took my details then put me on hold 'for a moment' - after 10 minutes the line went dead.
Rant over, sorry. I've had the new screen running for half an hour now, it was a mighty shock to the system at first but I reckon I can get used to it
The driver & instructions CD arrived warped, unplayable, and there's nothing on the web for this model yet. It'll be interesting to see whether proper drivers make much difference.

It would help if they employed any I guess ;-)

I said my rant was over, but I forgot the bit which really started to get me angry with them. They want you to do everything online, so I started by sending them an email. I got an automated response saying that, because they were so busy, it would be 5 or 6 DAYS before they dealt with my enquiry - about my parcel which should have been delivered 'next working day' & hadn't arrived for 4 days.

That's precisely what happens from the Swansea depot too. For sheer incompetence & lying they are exceeded only by Tony Bliar & his scum. On one occasion the son of our next door farm was actually driving from this depot, yet they chose another driver to "deliver" with the usual result. Added to that, on two occasions the drivers have failed to negotiate our track ( which strangely is OK for coal lorries) & have got stuck in the field. Second time this happened I left him to it & when I got back it looked like a Somme re-enactment had occurred.
