Just be careful when buying new eye glasses/spectacles

When I was working I had my varifocal glasses bought for me because I needed them to see the PC screen and every pair (about 10 pairs over the years) had the anti-glare coating.
Since retiring (about 4 years ago) I have bought my own glasses and continued having the anti-glare coating and have had no problems - no colour cast at all.
My current pair are about 2 years old (should go to the opticians) so I wonder if the anti-glare coating has changed recently. Thanks for the warning, Donald.

Just a small side note about specs lens coatings that have a colour. I've been using specs since I was about 11 – I'm now 65. No anti reflective coating should change colour values (as the optometrists term it). Coatings that go dark as a result of exposure to UV – e.g. photochromic lenses / coatings, usually come in two “colours” when dark – Brown, which will (actually, must) give a colour cast and Grey which will not.

In that case, grey, the white will be different with or without glasses and the 'very' dark will stay the same. It's still not a wanted situation for a person that has to examine a photo.

Hello Donald and Everyone,
This is to say thank you for a valuable read. I appreciate your posting.

THIS IS ALSO TO CONVEY and SHARE the following:
My spouse and I are looking for a new laptop. As many of us know the surface on their monitors come in several implementations: "anti-reflex, glossy, matte"!

Our brief study (without any firm conclusions made at this time) gave us the insight that the same holds true for the monitors vendors are offering.

Nevertheless to at this stage help everyone here, among other things, a monitor with anti-reflex may sound like a good thing. When thinking about the area of post-processing, I would think twice ...

Have nice day from Scandinavia! :)

Wear the glasses and look at the monitor and it puts a colour cast onto the screen. Now that's fine for everyday usage. But for post-processing ....! No way. It would alter things significantly.

Hi Pica,

If you'd like serious advice on the topic of laptop/monitor selection, you really need to start a new thread, suitably titled to draw answers. It will be lost in this one.

However, to answer your main point; personally I would only ever want to use a matte/anti-reflective screen for photo editing - I see enough of my face in the mirror, I don't need to see it leering at me while I'm trying to edit photos :D

That said, most/all touch screens seem to be the glossy variety (I guess they are easier to clean finger marks off), so if you wanted 'touch' to make most of Windows 8, 8.1 or 10, then that may be that's a problem.


Another important criteria for photo editing is that the screen should be 'IPS' technology (In-Plane Switching), not 'TN' (Twisted Nematic), that is because the latter (TN) is usually very sensitive to vertical angle of viewing, and gives significant variations of brightness if you're not looking 'square on' to it (e.g. as you would a mirror). If you're slightly above or below it, looking at an angle, a TN display may not give the same brightness (black level) as it should.

Hello Dave,
My purpose with this post was not ask for help. It was to share my experiences in the same area as the OP. That problems may occur during post-processing due to the chosen surface of a monitor.
I may have a few posts and threads here at this time. However this only due to that the successful forum Elements Village closed after many years in service and I chose this forum. Okay? :)

That said, thank you for bringing up an item on my to-do-list! :D The item of IPS technology. I know about the concept, however not its advantages.

Thank you for the dialogue Dave!
