Zeiss lenses might be a bit OTT. I wear glasses and have the standard specsavers lenses but with their own anti-glare and anti-scratch coating. Works a treat. It made a hell of a difference to that awful star-shaped sparkle I used to get from normal glass lenses.

That's what the government want you to believe of me. If they get back in I'm emigrating.

I used to suffer from those sort's of problems when I wore specs. I resolved the issue by sitting under a large machine which zapped away until my eyesight was nigh on perfect 6/4 (that's two lines under an opticians chart) which ain't half bad from a -3.75 shortsighted prescription...

As a byproduct of the laser treatment, they use a "mapping" thing to "re-work" your eye to be almost perfect. Apparently some military thing a while ago said they were considering sending pilots to be laser'd just so they could have very good night vision.

I have now, and it's great no dazzle unlike when I wore specs.

Although, I went to Moorfields Eye Hospital (The place to go IMHO) to have it done rather than one of the "shuffle-in , shuffle out" one's that send junk mail and advertise on tv

Unfortunately, it doesn't work for everyone... I have exceptionally good night vision, partially because my pupils will open very wide; to the extent that according to my optician, if I have laser treatment I'll be in danger of seeing "outside" the lasered region (which is only 6mm) and will thus be looking partially through the peripheral scarring (slight though it is) - which will give me all sorts of "scatter" problems at night. So, I'm "unlasered"... And quite p*ssed-off about it!

6mm is (i think) one particular area, just remember your optician really really doesn't want you to have laser surgery undar any circumstances.

I know it doesn't work for everyone, however IIRC the machine moorfields use can go to 8mm. I'd be giving them a ring, the consultants are really good and will ring you back.

Bugger! I "do" something over 9...

But I will give them a ring. Ta for the "heads up".

I think SE will bear me out in this - certain sections of industry,especially rail, found this - and if i remember rightly - certain jobs are barred if laser treated as a result of scatter/ and other effects that my employer has advised us about - not seen on the nice ads on telly though.

I'd go along with all the comments regarding having scratch-free and AR-coated lenses, and for keeping your windows (outside AND inside - the thin and barely visible film that slowly builds up on the inside can cause more scattering of light than any obvious drt on the outside...) spotless.

I recently replaced some 5-year-old glasses, and despite there being no change in the prescription, the difference in clarity between old and new lenses was startling. I knew the old lenses were a bit scratched, and the AR coating was wearing off around the edges, but I hadn't realised just how degraded my vision had become, so slow had been the change. The first time I put on the new glasses, everything looked so sharp and bright, it almost hurt... I'd put up with a bit of dazzle when drivng at night, thinking it was just the way it was, but these new lenses have all but eliminated it.


On a semi-related note, do any other glasses wearers find certain colours get shifted left or right depending on whether you look at them through the centre or edges of your lenses? Mostly seems to affect the red end of the spectrum for me-makes for some interesting effects when looking at red-ringed roadsigns out the corner of my eye... at/above a certain distance from the VSL signs on the M25, I can shift the red ring far enough such that the limit numerals are no longer inside. Not that I'd ever consider using that as a defence against a speeding charge
