New eyeglasses - anti-reflective coating is sapping out my diamond''s fire!

[rogue]

I got my new eyeglasses last Friday. I''m convinced that the anti-reflective coating on these is making me see less of the fire in my stone. My previous glasses had anti-reflective coating as well, but this pair''s AR coating is different, and inferior in my opinion. When I stand in front of a bathroom mirror with bare light bulbs, I see the bulb glare very clearly with my new glasses, but with my old glasses, it''s much more subdued. Then I started noticing my ring. Under extreme spotlighting, the fire is muted. But when I put on my old glasses or use just my eyes, the fire is vibrant. Very sad!!

Anyone else experience this? And it''s so ironic that the AR coating that is minimizing the fire is actually insufficient when it comes to certain types of glare! The pain.

I can''t imagine how this could be.

 

[indecisive]

I notice I see less fire from my diamond through my glasses than with just my eyes but I don''t know anything about the coating. I know what you mean... it sucks

 

[JulieN]

happens to me, too, but don't know if it's AR. seems likely, though, as it decreases glare...? and vision is "crisper" with AR than without, which, to me, reduces the size of fire.

I thought I was imagining it until I put my old glasses on. Very strange that even though the old pair has AR, it doesn''t seem to have the same negative effects as the new pair. Sad.

Get some contact lenses.

Or Lasik!

Hate to burst you bubble, "strong eyes-ers", but you'll never see as much fire as us "half-blinds without glasses". You are the lucky one rogue, fire-wise.
Take them off and enjoy!

I noticed the same thing when I got a new pair of glasses also and the distance that is best for looking at them changed.

New Rx glasses usually means you got a new prescription to compensate for your eyes changing.

Things in focus are smaller than things that are out of focus.

Is it possible the old glasses caused things at that distance to be slightly out of focus (which makes flashes of fire look bigger)?

Your new glasses brings things at that distance into sharper focus (which makes the flashes look smaller)?

I don''t know Kenny - my new prescription is stronger than my old (-5.25 versus -4.50), but I think that only comes into play for distance. I am near-sighted and see close-up images the same with both my old and new glasses, I think. And I noticed the fire change not only at a distance but also very close to my face, where presumably the increase in prescription has a minimal effect.

On a slightly unrelated note, I recently bought a pair of Maui Jim polarized sunglasses. I was looking out to the ocean on my recent trip to San Diego and noticed the water was blue and green. I took off the sunglasses and the water looked a uniform blue. I was told that I was able to see the green because of the way the polarized lenses cut glare and reflection. I guess all this just leads me to believe that lens coating has a lot to do with visualization of color. I of course have no idea what I''m talking about though.

Hmm, now thats a new one I have never head of. I am VERY nearsided (-10 in one eye and -9 in the other eye.) I usually wear contacts but do wear glasses in the evening when I''m home or if I ''m tired. I have always had antireflective coating and notice ZERO difference beween when I have my glasses on or contacts on in my rings.

Maybe your prescription is wrong? Or maby your glasses arn''t just the coating but they are tinted??

Before I read this thread, I had never really looked at my diamonds without glasses (very near-sighted), but today I took them off and what a difference!!!! And yes, I do have AF coating.

It''s not much about coating, it''s about focusing with a corrective device (contacts or glasses) what was out of focus, as Kenny said.
Rogue, you probably saw the same amount of fire with your previous glasses when they were new (read: correct for your sight) as you see now with the new ones.

 

[WTNLVR]

Whatever the reason, I definately see a differance without glasses. I guess I have to go get contacts now

(I also have the coating).

This set of photo''s of a 9ct daimond taken outside ubder a tree shows the effect of being out of focus.
the blurry shots are where the camera focused on the reflection of the branches above that came off the table. note how much more fire they show?

When I do not have my glasses on but have the diamond about 3 inches away from my face, it is completely in focus since my vision that near is totally clear. However, when I put my glasses on and have the diamond that close to my face, even though it is similarly in focus, the fire is not as great. So with 1) naked eye, 2) old glasses, and 3) new glasses, the focus three inches from my face is the same, so I wonder if it really is a matter of focus in some cases.
