Eye Floaters Cause Blindness

Signs You Are Going Blind

What are the signs you are going blindé If you can't read street signs from thedistance you used to, you may be going blind. Or need glasses. How can I tell the differenceé If things get blurrier over time, you mightbe developing cataracts, as the outer layers of the eye become like scratched up glass.Or you're becoming nearsighted and farsighted as the lenses stiffen. I've never heard of having both nearsightednessand farsightedness in one person.

What do you think bifocals and trifocals treaté I'd like to know something that is a signof actual blindness, not needing glasses. If you've had a head injury or stroke andnow have part of the field of vision turn red or dark, get to a to check theretina. And get to an eye if you have floaters. What are floatersé If you have floating spots in your field ofvision, that is a possible sign of vision problems. It is serious if you have red visionor head pain at the same time.

Or it could be a sign of old age. Blurred vision, seeing colored rainbows andred eyes are signs of glaucoma. And glaucoma is one of the leading causes of blindness. I thought that could be treated with surgery. Surgery can ease the pressure in the eye.And they may give you medicine to treat the blood pressure and underlying cause. Diabetes. Diabetes is not glaucoma, but the deteriorationof the blood vessels that causes so many diabetics

to lose kidney function and their feet canleave them blind, too. Yet another reason to lay off the sweets andget up and get moving. Or at least manage your blood sugar properlyin old age. But if it saves your vision, eating almostanything is worth it. I never would have thought I'd want to seeoat bran and prunes as an old person.

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
