A human hair is around 100 μm in diameter, a blood cell is 7 μm, a cone near the fovea is about 4 microns, and a rod is just 2 microns. The left side of the image is a zoomed out view of the cones.

In both the zebrafish acute zone and the human fovea, visual acuity is at its highest. "Because of this similarity, zebrafish are really good models to help us understand how the human eye might work.

Hartridge's observations in Nature of July 20 were correct, the stars should appear to change colour as their light falls upon different cones of the fovea. Prof. Hartridge, in reply, says "Dr ...

In the human fovea, the density of cones is much higher than that of rods; while in the mouse retina, the number of rods predominate everywhere… Since cones have different spectrum and intensity ...

The humble zebrafish can pick out tiny details in its environment just like a human spotting a faraway star, a study has found. The fish, named after its stripes, sees these objects through a ...

A specialization for high resolution vision The fovea is a region in the human retina in which the light-sensitive cells are more closely packed together yielding higher resolution vision.

University of Pennsylvania vision scientists report that dogs, too, have an area of their retina that strongly resembles the human fovea. What's more, this retinal region is susceptible to genetic ...

A human hair is around 100 μm in diameter, a blood cell is 7 μm, a cone near the fovea is about 4 microns, and a rod is just 2 microns. The left side of the image is a zoomed out view of the cones.

The findings were published in Nature Communications on the 29th June. The fovea is a region in the human retina in which the light-sensitive cells are more closely packed together yielding higher ...
