what is a lazy eye ??

Question

I have a lazy eye (left eye) and i dont know what a lazy eye is, I wear glasses but not all the time.

Answer 1

It means that one of your eye muscles is weak. This means that, especially when you are tired, the opposite muscle of the same eye, tends to pull the towards it. This produces a squint. If this is present all the time the two eyes are constantly pointing at different things and this produces double vision. Eventually the brain, as a defence mechanism to avoid this, does one of two things, it either blocks out one image, which makes you effectively blind in that eye as far as the brain is concerned, or in some cases it allows the eyes to work independently ( like all owls can do anyway). The problem in humans ( not in owls who can then switch to binocular vision using both eyes) is that we then tend to loose our binocular vision and select one eye at a time!

Answer 2

A "lazy eye" is a term applied to a condition of the eyes known as amblyopia. This happens when one eye is much weaker than the other eye, usually brought on by either a strong refractive error, or can also be caused by strabismus. In either case, because the stronger eye is doing all of the work, the brain sort of "tunes out" the images in the bad eye. As a result, the vision in the bad is lost.

Amblyopia must be caught early in childhood in order for it to be diagnosed and treated. Beyond the age of about 6, there really isn't a whole lot that can be done. Typically, once amblyopia is caught, the doctor will patch the good eye for several hours a day (some times all day) in order to force the brain to start paying attention to the weaker, or lazy, eye. This treatment is quite effective. Several weeks or months of this can re-train the eye and the vision is saved.

If the amblyopia is caused by strabismus, some times surgery to realign the eyes can help with the amblyopia. Strabismus is a condition where the eyes to not focus together on objects so realigning the eyes can help correct the problem, again if its caught early in childhood. I've known adults to get surgery done for strabismus, but it is simply to realign the eyes. If they had amblyopia as a child, as an adult the vision is still gone, but the surgery can help the eyes to look straighter.

A lazy eye is NOT when one of your eyes doesn't open as far as the other. Drooping eyelids, known as a ptosis (toe-sis) is another condition that can be surgically corrected but is in no way related to a lazy eye or amblyopia.

Answer 3

I have a lazy eye. It usually starts in childhood with a squint (one eye is slightly crossed). Because the brain sees a double image it "switches off" one of the images. This is usually the image on the left side if you are right handed. People who do not have the condition are amazed at the idea that you can deliberately switch between eyes. I found it useful for target shooting, as I didn't have to close the left eye, just ignore it.

Downsides are that you can never appreciate 3-D movies and as you get older you may end up with one long-sighted eye and one short-sighted eye. Then each image will be a different size when corrected with glasses.

Answer 4

It's when you stop using one eye (in your case, the eye you stopped using, the lazy eye, is the left eye). This happens for a variety of reasons, like one eye is much stronger than the other in terms of power, or if you had strabismus or cataracts or a head trauma. If you are old, it my be difficult to get back the ability to see well out of that one eye.

You usually can correct lazy eye by wearing a patch over the good eye. Alternatively, you may wear glasses with a lens that blurs vision over the good eye and forces you to see out of the bad eye. Again, it may be difficult to correct the problem if you are old by now.

Answer 5

The first photo is actually more useful. The reflections in the corneas are very symmetrically placed, which they would not be with a significant squint (turn, strabismus) There may be a degree of facial asymmetry, which almost everyone has, but that isn't a lazy eye either. A lazy eye, *which is undetectable to observation* if it is the only problem present, has the formal name amblyopia and is, and is only poor vision due to a lack of development in the eye when young, which does not immediately correct with spectacles.

Answer 6

A lazy eye is when the muscles that control where you are looking are not as strong as they should be. So people with a lazy eye look like one eye is wandering or not always focused on what the person is looking at. A lot of times wearing glasses will correct this.

Answer 7

when you're looking at someone, it looks like your left eye has gone to the shop, and the right one is coming back with the mars bar.

easily corrected, I had mine done under general ansethetic, the do it by shortening the tendons on one side of your lazy eye and make it central. If you've had it since birth, which chances are you have you'll find you suffer bad with double vision because your brain won't pick up that both your eyes are now working together and looking at the same place.

Sorry its a bit garbled, I couldn't think of how to explain it.

Answer 8

The more famous model in the world, Kate Moss has an lazy eye.
Look in some pictures.
Then, don't worry darling!!

Answer 9

It can mean a lack of binocular vision in which case each eye works independantly rather than together. If such a problem is detected very soon and the eyes have worked together before, then maybe it can be corrected by glasses but usually you just live with it.

Answer 10

A lazy eye is one that wonders out of focus. It will make you look cross eyed, or it will drift outwards. This id due to a lot of different things anywhere from muscle weakness to vision impairment. There are exercises that you can get from a low vision clinic that can help most of these.
