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
The first flashing light unit made and soldwas Nite Guard Back in 2006 we used them in a movie TitledRegarding Chickens. What's the purposeé They have a small red flashing light thatcan cause night hunting animals to avoid an area. They charge up automatically from the sunvia a solar panel. Charge during the day and then blink automaticallyall night long. Night Hunting animals see the flashing lightand then become stressed, thinking the flashing
light may be another animal. Then the animal will avoid the area and yourlivestock or bird feed is safe. The predator will walk down wind, trying tosmell the blinking light source. When they cannot figure out what it is, theconcept is that they will go away. Some people use these flashing lights in gardensto keep deer, raccoons and other garden browsers out. The main purpose of this tutorial is not to proveor disprove how effective flashing lights are, but to demonstrate how the four availableunits compare with one another.
There are four different flashing light unitsavailable, they do NOT perform the same, some are made better than others and offer morefeatures. Nite Guard has been produced for many yearsand was the first type that I purchased back in 2005. Nite Guard does not have an access for ownersto replace batteries. But many of the units continue to work even after many years ofyear round use. they blink less and don't last as long, but are still working. Several years later, another company madea new style of flashing light units. Solar
Nite Eyes. Works the same as Nite Guard, BUT has a magnetfor mounting on metal surfaces and has two flashing led lights. Larger solar panel on Nite Eyes and two leds. There may be no difference between the twoas to weather one keeps predators away more than the other. In this regard, they performthe same in my opinion. After just one day of charging on the windowsill, they will faithfully blink through the night and turn themselves off at sunrise.
Predator Guard made some very helpful changesto the original designs. they have added a onoff switch and slanted the solar paneland added a magnet. The magnet allows you to change the positionfrequently onto anything ironsteel so that predators do not become accustomed to thelocation. keep them guessing. The angled solar panel will help keep snowfrom covering it and keeping it from charging properly. Does not come on automatically unless theon off button is pressed. this allows you to store the unit without the battery runningdown. The only style of flashing light unit
that has this feature. The other units will run down completely ifstored in a dark place. Just before I made this tutorial, another flashinglight unit showed up on the market, so I purchased six of them for review. It's called Yard Sentinel Predator Eye. 12 the price of all of the other units, youcan purchase a package of two for 24.00 Appears identical to the first design (NiteGuard). They appear identical on the outside.
