The maculais the bull's eye at the center of your retina. The dead center is called the fovea. Because it's the focal point of your eye, it has more special, light-sensitive nerve endings, called photoreceptors, than any other part. Photoreceptorscome in two kinds: rods and cones. They...
We'd love to work with you. Let's chat.The retina Retinal tissue covers much of the inner eye, and contains special neurons called photoreceptors. Macula & fovea The macula is a spot near the retina's center that contains the fovea. The fovea is a pit of densely packed cones for ...
1“Growing fruit trees is a very simple way to stay in love with our world,” says Vivian Keh, playwright and daughter of immigrants, holding a basket of persimmons she’s cultivated to feel connected to her Korean ancestors. Keh is just one ofthe50 remarkable subjects in naturalist writer ...
In the back of the eye, in the center of the retina, is the macula. In the center of the macula is an area called the fovea centralis. This area contains only cones and is responsible for seeing fine detail clearly. The retina contains a chemical called rhodopsin, or "visual purple."...

Cones function in brighter light and provide color vision. Cones are sensitive to particular light wavelengths such as red, green and blue light. Optic nerve fibers These ganglion cell roots or “axons” are intertwined throughout the optic nerve and extend into the brain. Retina function Light ...
The eye can be compared to a camera Rods and cones - retina visual cells Emmetropia - You have no refractive errors Different visual errors How does our vision work? All visual impressions arise when light rays from the surroundings enter the eye through the pupil. Through the cornea, the ...
Scientists suspect that bees and flowering plants both evolved around 100 million years ago, in the middle of the Cretaceous period. Before this period, many plants reproduced the way today's conifers do. They released seeds and pollen using cones. The wind carried the cones, and eventually th...
Spheres can also be more easily tested for frustum and occlusion culling, as we will describe later in the chapter.The next additional piece of data that we’re going to use is the meshlet cone, as shown in the following screenshot:Figure 6.3 – A meshlet cone example; not all cones ...
There are people who are blind to certain colors. Human color blindness is hard to explain. In a single eye, there are millions of very small things called “cones.” They help us to see in bright light and to tell the difference between colors. There are also millions of “rods,” bu...
