Thinking about upgrading my eyes...

Tanuki · Post by **Tanuki** » 03 Aug 2009, 19:00

I currently have standard-definition eyes and am trying to decide if I should upgrade to HD eyes now or wait until the government-mandated analog to digital photon conversion.

I am thinking about these.

Thoughts?

AKA...plugging the last "analog hole", ha! Big Content cheers!

Those glasses would be mighty tempting if they came with cobalt blue lenses. Puke yellow? Pass.

seems like BS to me

Sun glasses do improve color vision on most people, polarized glasses also help with this.

Still though, it's infomercial BS (yes, they have one for this product), because this is not in fact anything new or unique to this product. Polarized glasses have been able to do this for years.

These days it's not what you sell, it's how you sell it. There are so many suckers out there thinking they got a once in a life time deal on something.

Yellow glasses, I've seen them at work. And they do give you better sight somehow, I tried it.

But the yellow colour isn't your everything...

yes filters can improve some parameters in your vision ... sharpness, details ...
but a yellow filter will turn white to yellow, so I won't say it improves colors ... it's just a trade-off.

plus yellow/polarized glasses like that shouldn't be used in snow/beach/too sunny environments unless you want to damage your eyesight...
(by reducing perceived light they make your iris open more, yet all damaging effects of sun are unfiltered ...)

all in all that's pure commercial bullshit.

I stick with nature's method: squinting. :onethumb

This is all old stuff and have been available in one form or another for a long time. The Night driving ones do work if you do long trips at night. I used to get an extra pair of prescription glass made with the yellow tinted lens when I was making 2 300 miles trip each month. It does cut down on fatigue on long drive as it dims the oncoming headlights without affecting your night vision.

I used to do a lot of mt biking, often times driving home in the dark. My eyes are very sensitive to a combination of light and dark, so headlights coming at me at night, especially with the glare rain adds, is very straining. I took to using a cheap pair of pale yellow glasses for night driving. They bring out the contrast without being overly dark and make the bright lights and glare juxtaposed to the dark much easier to take. They're commonly used for shooting glasses too.

True. I have a pair.

Bono wears a pair of yellow sunglasses all of the time. Yeah.

That's why they need to be UV A/B blocking.

exactly but according to my local glasses retailer, yellow sunglasses aren't up to the standard enough aka even if they advertise some degree of UV A/B blocking it won't ever be enough...

edit: and he sells all sorts of glasses , among them said yellow ones

To be honest, I thought yellow glasses were supposed to reduce eyestrain of short-term sudden variations in brightness (such as when shooting, or being on a ski slope) rather than be a 'cure all' or standardised sunglasses.

I don't really favour yellow glasses anyway - although I did quite like the light brown lenses my last sunglasses had... after I got used to them. They weren't perfect, but I tested them once by sticking them in the beamline of a UV/Vis spectrophotometer - they maxed out the absorbance below 350nm, so they were certainly blocking a lot of UV. :)

Note that the only yellow glasses in that ad are the bonus "Night Vision" pair. The yellow ones aren't intended as "sunglasses". The actual sunglasses in that ad are more of a amber/brown color.

So have you worked in just about every field that begets movie villians? ;) :P

Um... no.

A fairly typical flavin UV/Vis spectrum - it's not quite 'typical' as that would have maxima at 350 and 450nm. It's a thiol oxidase, which I've never worked on personally. The big peak that maxes at 280nm is the protein, the 'double bump' with maxima at ~370nm and 450nm is the characteristic flavin optical spectrum. Oxidised flavin looks yellow. Anything below about 370nm isn't visible as it's UV - putting my glasses in the beamline makes the readings below 350nm hit 10 (which is the maximum absorbance that the spec I used registers...) The amount of protein-bound flavin is actually fairly low in this example... I doubt that more than 10% of the protein has a cofactor bound.

I confess, you lost me at "flavin".

Just kiddin around about the movie stuff. It must be pretty handy to be able to find out for yourself if a product's claims are total BS or not. Wish I had that ability for a few things I've purchased.....

Sorry.

Biochemist geek mode: off.

No worries about the movie stuff, I know you're kiddin'.

Yeah, it's pretty good to be able to test stuff at times.

There are lots of things I want to test that I can't, however... :(
