Watch the secret to a squid's crystal clear underwater vision
Science Magazine
It's hard to see underwater, and not just because of the chlorine. The image-producing light rays that enter our eyes have trouble bending and focusing when the water's density is almost same as that of eye fluid. Sea creatures experience the same ...

Squid eyes reveal molecular secrets for smart lenses
Cosmos
Squid are among a select few species of animal in the world whose eyes involve perfect lenses, capable of focusing all rays of light to the same convergence point. Until now, however, the molecular structure behind this peculiar feature has largely ...

Globular proteins found to allow squid eyes to adjust for light distortion
Phys.Org
(Phys.org)—A team of researchers with the University of Pennsylvania has uncovered the means by which squid eyes are able to adjust to underwater light distortion. In their paper published in the journal Science, the group describes their work ...

Eye patches: Protein assembly of index-gradient squid lenses
Science Magazine
When light rays pass through a curved lens, greater refraction at the edges can distort the resulting image. This problem can be overcome if the refractive index of the lens is varied according to the curvature. Cai et al. show that the lenses of squid ...

Squid eyes have it — perfect lenses that could inspire advances for human vision
Newsworks.org
Squid lenses are better than any lenses we can make, and scientists have figured out why. The research is early, but eventually it might lead to better lenses for us — and for cameras. We can't focus perfectly on everything that we see, because our ...

Squid see clearly in low light using linked proteins
physicsworld.com
The eyes of squid and fish are miracles of evolution, producing bright, sharp images with limited light. How they do this, however, has been a mystery. But now researchers in the US have analysed the lenses in the eyes of a common squid species and ...
