Sunglasses see through outdoor cooking smoke?

I was cooking outside on a sunny day and so wearing some sunglasses (blocking the UV 400nm light spectrum) when I noticed it easier to see the food in the cooking pot compared to the naked eye.

Has anybody else noticed this?

Is there something about the 400nm light spectrum that makes it easier to see through smoke?

It makes sense. Smoke scatters, reflects, and blocks light, as do clouds. The sunglasses you were using were probably polarized, wichwould block the scattered light, making it easier to see the direct light from what you are looking at. That's my hypothesis.

Thanks for the info.

Actually, the pair I got came with several lenses, one of which was specifically polarised, so I can try with a number of different combinations.

I will get back when I have done so..

Anything UV blocking and coloured works

Hardly scientific, and with the wind blowing and at times overcast the lighting and smoke will be off, but I tried my best to capture the smoke coming from the pot to contrast the difference.

I have five lenses:

• Blue
• Yellow
• Clear
• Rainbow
• Parallax


All of these lenses block out the 400nm lightwave range (I have confirmed this with a 395nm wavelength UV torch (TANK-007)), but only one seems to have a parallax lens. I don’t know how to confirm this, but I found it to be the only lens of which distorted an LCD (passively) and expect it to be different.

Of all the lenses I found little difference, they all seemed to make it easier to see the poultry beyond the smoke, of course if the smoke was to thick then it would be obscured, so the glasses only helped.

I didn’t find that he parallax lenses did anything more than the coloured ones, I think the colour seems to define the texture of the meat (which is diced - in this case shredded, like pulled pork in some instances) better, I don’t think it matters if the lens is parallax or not ?

I have a preference for blue, I think it works best, but anything that dims the light works well i.e. parallax or rainbow (which blocks out the most light from all five). However, I stay away from yellow as it tints the meat too much and makes it harder to judge whether the meat is browning, although clear works as well, tinted is the way to go.

Here are decent sizes of the coloured lenses:
