How can you see things with your eyes?Angels55 - 7 Answers
Oh.I see what you were asking now! But i didn't know that or even think about the composition! thanks for the info!
Any eye-dea what the protein is named or does it have a very regular structure? Just curious (oh and I'm going to want to know the crystal shape and lattice structure. j/k)
Since I assume there is nothing more to answer, I will just ask, any other idea about how this is related to ulcerations and fluorescein stain/cobalt blue filter. Is the crystal some type of helical shape maybe ( I'm thinking of like heparin or starch.and POV-I all having similar structures and how (I3-) stains starch blue by slipping into the helix neatly, and while fluorescein is much larger than (I3-), so is Ethidium bromide, and it stains DNA by slipping between two adjacent base pairs sets.
Egg => (proteins denaturing)
The new shape therefore a different molecule in the secondary, tertiary and quantirary sense anyway. Still a different physical property of the opaque color is comparable to the refractory differences between the Aqueous & Vitreous humor, the lens and the corona.
The Lens is biconcave so it focuses light through its center and results in a inverted image. but the image would still be distorted when it focused on the retina since it is not flat, but semicircular, even though the majority of the focus is in a single spot (the Macula), which is very rich in cones for color sensing, while rods are found more concentrated in the outer areas of focus on the retina, which is apparent if you try to use your peripheral vision in a dark room!
Passing through the vitreous humor which has a higher refectory index, bends the light like looking at a pencil through a glass of water, and allows the half spherical shape of the retina to focus evenly on the image projected onto it.
Now we have looked at it and received stimuli from the rods and cones that interpret contrast and colors respectively. This causes individual optical nerves to fires repeatedly as they conduct image data from node to node and quickly actively reestablish their action potential as the afferent nerve pulses become bundled in the optic nerves, and continue traveling anteriorly until they cross one another along the medial plane and the optic chiasma lease them through array after array of neural networks to interpret the information and finally be considered "seeing".
Each array of inter-neurons interprets a different portion of the image, such as one may find horizontal lines and make one aware of them, where another is in charge of vertical lines, still another may tell us where the brightest areas are in the field of vision. This all adds up to what we eventually "see" the question is...what sees it?!
In fact, though you can't bring yourself to realize it, the cornea forms a crystalline matrix of protein, which is why it is transparent to light. It does absorb UV light and for that reason and that there are no UV receptors in the retina, we cannot see in the UV....
Basically because the cornea, lens, vitreous and aqueous humor are all clear and light will pass through them.
The lens of the eye and also the cornea will then bend or refract the light rays and focus them on the retina.
To help with this question, consider the egg white which is transparent until you cook it, then it is opaque. Why is that?...
You don't see with your eyes, you see with the brain....
Why are the cornea, lens and so on transparent?...
