通过打破双眼冗余增强人类色觉
Enhancement of human color vision by breaking the binocular redundancy
入门 · 约 30 分钟读完前置知识:三色视觉理论、色彩感知基础
导读
这篇论文研究能否通过打破双眼视觉的冗余来增强人类色觉:给左右眼分别佩戴互补的滤光片,使两眼接收不同波段的光,从而在大脑融合后获得超越正常三色视觉的色彩分辨能力。作者报告这种方法可以让观察者感知到原本无法区分的颜色差异。
HN 关注点:HN 读者对'人体感官增强/生物黑客'话题一直很感兴趣,讨论焦点是这种双眼分色方案是否真的可行,以及它与色盲矫正眼镜等已有技术的异同。

这几条评论里:补充 3 亲历 1
补充作者早在一年多前就提出过几乎相同的思想实验,与论文思路不谋而合
我忍不住要说,418 天前我发过一条评论,这应该是'不谋而合'。当时我做了个思想实验:把可见光分成六个波段,做两种滤光片,一种只通过 1、3、5 波段,另一种只通过 2、4、6 波段,左右眼各戴一个。时间长了,人能否学会用六色视觉看世界?

I couldn't help but remark on this. I posted the following comment 418 days ago. I am sure this is a case of simultaneous ideation. 3 points by louprado 418 days ago | parent [-] | on: Life in Technicolor – One month wearing color blin... While many of us are not "color-blind", we are all color challenged. This is because we only have three cone-types, assuming you aren't a tetrachromat. I had a thought experiment: Suppose you breakup visible light into six bands. You then create two filters based on these bands. One filter would pass only bands 1, 3, and 5. The other filter would pass bands 2, 4, and 6. Now suppose you put one filter over your left eye and the other filter over your right. Over time, could you learn to see the world in hexachromatic color ?
补充对比色盲矫正眼镜的原理,好奇两者能否结合进一步提升光谱分辨力
这真的很酷。我原以为它可能和色盲矫正眼镜(如 EnChroma)的原理有关,但那些眼镜只是用特定透射光谱的镜片,让较低频率的红色和较高频率的绿色通过以增强区分度。不知道能不能把两者结合,获得更高的光谱分辨率?

That's really really cool. I thought it might be related to how glasses for colour-blindness work (eg. http://enchroma.com/technology/ - just the first one I found) but apparently they just use lenses with a specific transmissive spectrum to let through mostly lower frequency reds and higher frequency greens to improve differentiation. I wonder if you could combine the two to give even more spectral resolution?
亲历亲历者分享左右眼天然色感不同的体验,且都与出色的色彩能力相关
我的两只眼睛看到的颜色本来就略有不同:一只偏蓝,一只偏红。我是画家,在色彩测试中得分最高。我一位摄影师朋友也有同样的情况且色彩敏锐度极佳。还有其他人有这种体验吗?

I already see in slightly two different colors in each eye. One is more of a blueish hue, the other more ruddy. I'm an artist and in color tests, I get the best marks. My friend who's a photographer also has the same condition and excellent color acuity. Anyone else experience this?
补充补充传闻:摄入维生素 A2 或可让人看到红外光
是不是有个技巧:不吃通常类型的维生素 A,而只吃另外三种中略有不同的那种,就能获得夜视能力?我记得好像不是夜视,而是能看到紫外线。也可能是我做梦梦到的。更正:是维生素 A2,用于夜视——实际是看到红外光,不是在黑暗中看东西。

Isn't there some trick where you don't consume the usual type of vitamin A but instead only consume one of the other three types of vitamin A? The one that's slightly different and somehow you get night vision? Actually I don't think it was night vision I think maybe it was to see UV light. Maybe I only dreamed this not read about it I tend to do that sometimes. edit: It was vitamin A2 and it was for night vision actual IR not to see in the dark but to see IR light. http://www.popsci.com/article/diy/can-we-hack-our-vision-see-infrared-naked-eye
