    2:02 if light focuses precisely on the retina then all colors should combine at the same point and make white and everything would appear white color to us, i think it should focus slightly front of retina(1:18) so different wavelentgh light waves can activate different cones to make 2D image of object

    • @supertubemind
      @supertubemind 4 роки тому

      You are confused. If the light coming in is white, it would be perceived as white. If the colour is not white, eg looking at a coloured object, then the three cones would detect the different primary colours but these would be in different amounts and they would recombine to form the colour of the object and not white light. Your attempt to redesign the eye is misguided.

    The eye is the organ of sight and is shaped as a slightly irregular hollow sphere. Various structures in the eye enable it to translate light into recognizable images. Among these are the cornea, the lens, and the retina.
    Light first passes through the cornea, a clear dome-like structure covering the iris, or colored part, of the eye. The cornea bends, or refracts, the light onto the lens. The light is then refracted a second time while passing through the lens, finally focusing on the retina. The retina is the light sensitive part of the eye. Impulses travel down the optic nerve to the occipital lobe of the brain, which then interprets the image in the correct perspective.
    The shape of the eye is very important in keeping the things we see in focus. If the shape of the eye changes, it affects a person’s vision.
    Normally, light is precisely focused onto the retina at a location called the focal point. A nearsighted eye is longer from front to back than a normal eye causing light to be focused in front of the retina instead of directly onto it. This makes it difficult to see objects that are far away. Glasses with concave lenses are used to correct nearsightedness. The concave lens focuses light back onto the focal point of the retina.
    Farsightedness occurs when the length of the eye is too short. Light is focused at a point behind the retina, making it difficult to see objects that are up close. A convex lens is used to correct farsightedness because it directs the focal point back onto the retina.
    How Your Eyes Work
    When light rays reflect off an object and enter the eyes through the cornea (the transparent outer covering of the eye), you can then see that object. Rods and Cones in the retina
    The cornea bends, or refracts, the rays that pass through the round hole of the pupil. The iris (the colored portion of the eye that surrounds the pupil) opens and closes, making the pupil bigger or smaller. This regulates the amount of light passing through.
    The light rays then pass through the lens, which changes shape so it can further bend the rays and focus them on the retina. The retina, which sits at the back of the eye, is a thin layer of tissue that contains millions of tiny light-sensing nerve cells. These nerve cells are called rods and cones because of their distinct shapes.
    Cones are concentrated in the center of the retina, in an area called the macula. When there is bright light, cones provide clear, sharp central vision and detect colors and fine details.
    Rods are located outside the macula and extend all the way to the outer edge of the retina. They provide peripheral or side vision. Rods also allow the eyes to detect motion and help us see in dim light and at night.
    These cells in the retina convert the light into electrical impulses. The optic nerve sends these impulses to the brain, which produces an image.
    The human eye is an organ that reacts to light and has several purposes. As a sense organ, the mammalian eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors and is possibly capable of detecting a single photon.
    Similar to the eyes of other mammals, the human eye's non-image-forming photosensitive ganglion cells in the retina receive light signals which affect adjustment of the size of the pupil, regulation and suppression of the hormone melatonin and entrainment of the body clock.
    Visual perception is the ability to interpret the surrounding environment by processing information that is contained in visible light. The resulting perception is also known as eyesight, sight, or vision (adjectival form: visual, optical, or ocular). The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in Linguistics, psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science.
    Light entering the eye is refracted as it passes through the cornea. It then passes through the pupil (controlled by the iris) and is further refracted by the lens. The cornea and lens act together as a compound lens to project an inverted image onto the retina.
    The retina consists of a large number of photoreceptor cells which contain particular protein molecules called opsins. In humans, two types of opsins are involved in conscious vision: rod opsins and cone opsins. (A third type, melanopsin in some of the retinal ganglion cells (RGC), part of the body clock mechanism, is probably not involved in conscious vision, as these RGC do not project to the lateral geniculate nucleus but to the pretectal olivary nucleus.) An opsin absorbs a photon (a particle of light) and transmits a signal to the cell through a signal transduction pathway, resulting in hyper-polarization of the photoreceptor. Rods and cones differ in function.

      I heard a Doctor say that if a baby is blindfold at birth and the blindfold is then removed, after a certain amount of time the baby will never be able to see. And the reason has to do with the fact that man, with his large brain needed to be as efficient as possible so childbirth would be possible. the software comes AFTER birth for us, as opposed to a horse that does everything it ever does within minutes of its birth.

    it'd be much better if you stated that the lens was the one with the incorrect shape, as the eye shape really doesn't affect the placement of the focal point, whereas the shape of the lens does. If the lens is too thick at a relaxed state then the focal point falls in front of the retina, if the lens is too thin at a relaxed state then the focal point falls behind the retina.

    • @dankmemesstudios3987

      Ooo, good question! The answer would be yes... and no! We see objects when light is reflected off of them, then that light enters our eyes. The interpretation of what we see is based on our brains ability to make sense of it. Unfortunately, some peoples receptors that catch the entering light do not work as they are supposed to, so they either don't see it, or they see it distorted or they see it in a different color. And I won't even begin on what the brain can do with that information!!

    What I now say is a true experience I had: For a few years ago I was at our backyard and I watched at the trees. Suddenly without any advance warning I saw the trees upside down. The trees was where the sky should have been, and the ground was where the sky should have been. But just for a second or less. Then after a few seconds more it happened again. Again, only for a second or less. Then after a few years I watched a TV-program where a doctor was speaking about the human eyes, and then I understood what had happened to me that day. It had to do with my brain, and it was only for a second or two (2x1= 2) and then it was over. I have not experienced that thing anymore, and I thank God for that. The life would be a mess if you don't know what is up and what is down.

    ❤❤❤❤❤❤❤2.42..... timing ...... for correction of near sight problem we have to use concave lens........ u said also same in video.... but in the diagram that is not a concave lens..... its like a convex lens........ so better to avoid confustion at 2.42 timing concave lens matter❤❤❤❤❤

    I wonder if there's a disorder where the brain doesn't flip the image.

  • @harshitverma685
    @harshitverma685 2 роки тому

    But the rays are converging in the middle so why the image is being formed on retina
