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
Whats the Right Amount of Eye Contact
If I stare like this, do youfind you more persuasiveé How about like thisé Anthony here for D News. And we've often beentold that eye contact is the key to beingpowerful or persuasive. Whole books are devoted tothe power of eye contact
and how it's going to improveeverything from your job to your romanticlife, except no. See, some new findingswere just published in Psychological Science thatsay direct eye contact actually makes people less likely to bepersuaded by you, especially if they were skeptical aboutyou or your ideas before. How'd they figure that outé Well look me directly in theeye, and I will tell you.
Two experimentsexperiment one, using eye trackingsoftware, researchers measured the amount ofeye contact subjects made with thespeaker in a tutorial. The more they focusedon the speaker's eyes while they gave theiropinion on an issue, the less their attitudesshifted to match. Experiment twopeople were asked
to either look in a speakerseyes or at a speaker's mouth during a conversation. And people wholooked into the mouth were more receptive tothe speaker's opinion. The reason we're toldto use eye contact is that it exudesconfidence, but this study seems to show thatit's a confidence that comes from a place of tryingto assert dominance or use
intimidation. That's why animalsaren't into eye contact. It's confrontational. If someone doesn'tagree with you and you look themin the eye, there might be a whole set ofsubconscious psychological reactions that putthem on the defensive. Of course, it's situational.
In a closerrelationship, eye contact is a sign of connectedness. It's also cultural. Here in the US and a lotof European countries, a certain amountof eye contact is required to show that you'repaying attention to someone. In some Latin American,Asian, and African cultures, it can be consideredaggressive or disrespectful.
