What are those floaty things in your eye Michael Mauser
Have you ever noticed something swimmingin your field of visioné It may look like a tiny wormor a transparent blob, and whenever you try to geta closer look, it disappears, only to reappearas soon as you shift your glance. But don't go rinsing out your eyes! What you are seeing is a common phenomenon known as a floater. The scientific name for these objectsis Muscae volitantes,
Latin for quot;flying flies,quot; and true to their name,they can be somewhat annoying. But they're not actually bugsor any kind of external objects at all. Rather, they exist inside your eyeball. Floaters may seem to be alive,since they move and change shape, but they are not alive. Floaters are tiny objectsthat cast shadows on the retina, the lightsensitive tissueat the back of your eye.
They might be bits of tissue, red blood cells, or clumps of protein. And because they're suspendedwithin the vitreous humor, the gellike liquidthat fills the inside of your eye, floaters drift alongwith your eye movements, and seem to bounce a littlewhen your eye stops. Floaters may be onlybarely distinguishable most of the time.
They become more visiblethe closer they are to the retina, just as holding your hand closerto a table with an overhead light will result in a moresharply defined shadow. And floaters are particularly noticeable when you are lookingat a uniform bright surface, like a blank computer screen, snow, or a clear sky,
where the consistency of the backgroundmakes them easier to distinguish. The brighter the light is,the more your pupil contracts. This has an effect similarto replacing a large diffuse light fixture with a single overhead light bulb, which also makesthe shadow appear clearer. There is another visual phenomenonthat looks similar to floaters but is in fact unrelated. If you've seen tiny dots of lightdarting about
when looking at a bright blue sky, you've experienced what is knownas the blue field entoptic phenomenon. In some ways,this is the opposite of seeing floaters. Here, you are not seeing shadows but little moving windowsletting light through to your retina. The windows are actually causedby white blood cells moving through the capillariesalong your retina's surface. These leukocytes can be so largethat they nearly fill a capillary
Parts of Human Eye Blind Spot GAJHE08A
another important part of human eye is blindspot. this is. bellow the retina and the last part of human eye. and we can write aboutit that. the point. in the rear part. of eye. where optic nerve, is attached. optic nerveis, the nerve which carries the electrical signals from rods and cones to the brain wehave already discussed. and the point, bellow the retina and the rear part of eye, whereoptic nerve is attached is called. blind spot. in picture of human eye you can see this isthe blind spot where the optic nerve is attached to the eye which, carries the signals from.retina to brain. and, at the point of blind spot where the nerve is attached we can writeat this point. there are no. rods and cones.
in retina. this is a point where no cellsare there and as no cells are there whenever light falls. onto this point there wont beany sensation produced. so we can also write if some light. falls. or an image is produced.in this region. as no cells are there in blind spot region. we can say no signals are sent.to brain. and no object is seen, even if the image is produced. in the region of blindspot, the image will not be visible for human eye so in this region it can not be seen.
