Astigmatism is a refractive eye disorder which causes blurred vision. It is a fairly common eye problem can be corrected quite easily by using lenses or glasses or getting surgery. Normally, a person’s cornea is perfectly spherical in shape. When light enters the cornea, it is refracted equally in all directions and a focused image is formed on the retina. But when a person suffers from astigmatism, the shape of the cornea is distorted and so, a sharp focused image cannot be formed. This results in hazy and blurred vision.

Causes of Astigmatism

In majority of cases, this disorder is hereditary i.e. it is passed on from one generation to the other. Besides that, it is also common in people who spend a lot of time working in the front of the computer or who sue their eyes for activities like embroidery which require constant precision. Additionally, incorrect posture can also result in increased pressure on the cornea, which would eventually distort its curvature.

Symptoms of Astigmatism

So, how do you know if you are actually suffering from this eye disorder? The most obvious symptom is obviously blurred and hazy vision. However, blurred vision is a common symptom for many other eye disorders. But if you are indeed suffering from astigmatism, the objects will remain blurred even when viewed from very close distances.

Other symptoms of astigmatism include constant headache, fatigue, dizziness, eye strain and the inability to concentrate on a particular object. If you are experiencing any of these symptoms, you must visit your ophthalmologist who will be able to diagnose the exact cause of these symptoms after running a few tests.

Treatment of Astigmatism

The treatment for this eye disorder depends on just how bad it is. In most cases, the degree of astigmatism is quite mild and can be treated easily with corrective lenses. There are specific kinds of lenses for treating astigmatism called toric lenses. Your optometrist will decide the ideal kind of toric lenses for you after running some basic tests.

In case of high degrees of astigmatism, you can also consider refractive surgery. This surgery corrects the curvature and shape or your cornea making as perfectly spherical. Once this is achieved, the images formed will be sharp and focused as light rays will refract properly inside the eye.

As technology has advanced, various other forms of surgeries and corrective measures have emerged. In case you are suffering from astigmatism or are experiencing any of its symptoms, you should definitely visit your optometrist and discuss the issue with him.

However, if you are planning to buy glasses on-line, then you might need to know your own PD and since it could be bothersome to visit the doctor to only have the measurement taken, it will be best if you can do it yourself.

Here are some techniques on how you can determine your PD:

Of course, the initial option would be to go to an eye doctor and pay out a small amount of fee to have your PD taken. But because we’re looking at doing it yourself, here are some very simple steps:

1. Request a buddy to take the measurement for you. It would be rather challenging to get the measurement yourself especially if you’re aiming for accuracy.
2. Get a ruler (one which includes millimeters) and have your companion stand in front of you, holding the ruler horizontally under your pupil (or directly in front of your eyes).
3. Using a non-permanent marker, have your friend indicate the center of each pupil on the ruler.
4. Calculate the length between the 2 dots.

You can also try to download a printable ruler that is exclusively used to evaluate PD online. A lot of optical shops give their services online so you can locate easily website that gives a free download of the printable ruler. Again, you’ll require a friend to help you with the measurement.

1. After printing the ruler from the website, request your pal to stand at arms length away from you.
2. The printable ruler would often have a zero value. Request your buddy to put the ’0′ value in the center of the left pupil and assess through the middle of the right pupil. It is crucial that your buddy maintain the printable ruler right across your face to acquire a precise measurement.

When getting your PD, you must ensure that you’re looking straight to receive an accurate measurement. You can even do the measurement many times for additional reliability and have other buddies calculate it for you. After getting a number of measurements, find the average of values that your buddies have listed and list it as your PD.

Remember, while you are taking your rating, you should be as precise as you can because your PD will significantly determine the length of every frame for your eyeglasses. For additional precision, have a companion take the measurement for you and have it taken numerous times so you can be sure that your upcoming glasses will be finest fitted for you.

Causes for Poor Vision

One reason you may be experiencing a loss in vision is staring at a computer or television for longer periods of time. Decreasing the amount of time you spend at the computer is one way to correct vision – although this is not the only way. Wearing glasses may correct vision for awhile; however, even glasses and contacts can be harmful to the eyes.

The reason for this is that they actually weaken the eye muscles; this is why doing eye exercises can improve eyesight naturally because you are strengthening the muscles within the eyes. Just like any muscle in the body – if you don’t use it, you’ll lose it. Weak arm muscles make holding heavy objects difficult; just like weak eye muscles cause poor eyesight.

Improve Eyesight Naturally

Wearing glasses or contacts is not a way to improve eyesight naturally, because you are introducing a foreign object into your eyes. Not only does this weaken muscles, it can cause unwanted bacteria to enter the eye, which may actually cause blindness. If you increase the amount of eye exercises you do per day, then you will drastically improve eye vision without the help from an optician.

Here are just a few exercises that can help improve eye vision without doing much work at all:

Blinking – Zooming – Tracing – Focusing – Palming

Blinking is something you do naturally; however, increased focus at the computer or television can decrease the amount of time you blink. Each time you blink, you refresh your eyes, which reduces a certain amount of eye strain. Take a break and blink every three or four seconds for two minutes. Afterwards, your eyes should be more relaxed than before. It’s hard to believe that something as simple as blinking can help correct vision.

Zooming and focusing are very similar, and both exercises are done by placing your thumb in front of you and moving it closer and further from your eyes. Not only does it strengthen your eye muscles, it also improves your ability to focus.

Tracing can be done to improve eye vision by imagining a figure-eight in front of you and tracing it with your eyes. This exercise will help strengthen your eyes, as well as improve eye flexibility. It will be hard at first, but it will become easier the more you practice it.

Palming is a simple way to relax and improve eye vision also. By placing your palms over your eyes and resting your elbows on your knees, you are giving your eyes a chance to relax and refocus. All of these eye exercises are ways to correct vision without surgery and without the need for glasses or contacts.

Eyes are part of our body. They influence the body and are influenced by the body, simultaneously. So body diseases can lead to eye problems. People who suffer from diabetes related issues and who smoke a lot are more likely to lose his eyesight, as smoking and other diseases will result in the damage of blood vessels behind the eyes. If you are a heavy smoke or you are diabetic, you are supposed to go for a check once every two or four years. If you have a family history of y eye-related disease, you are supposed to take the examination once a year or two years. Even though you feel good about your eyes, you should go for a check regularly.

Some eye diseases are introduced after birth, and some are hereditary. We can do eye exercises or have a good habit of eye using to prevent after birth diseases. But we sometimes can not do many things to overcome the hereditary issues. More seriously, if the hereditary diseases are left untreated, you may completely lose your eyesight. So it is important to know some heredity diseases at heart. Here we will introduce glaucoma, one kind of hereditary eye problem.

Glaucoma is caused by blockage in part of eyes. The blockage in eyes leads to the build up of excessive eye natural lubrication at one point thus put much pressure on the eyes. There is nearly no symptom of this pressure, so you can not feel it at all. Some time later, the gradual build up of fluid destroys nerve cells in the eyes and finally lead to eyesight loss. It usually starts with a tiny blind spot in your peripheral vision, and it ends with the whole vision loss in the central vision. You even do not have time responding. The most unfortunate thing is that glaucoma can not be completely cured. There are only tablets, eye drops or surgery methods to treat with the disease. All the methods have a function by lowering the pressure of fluid in eyes to prevent any vision loss or damage. So if your glaucoma is found earlier, you are more likely not to lose your eyesight, at least maintaining your current vision.

Certain jobs make this rather impractical, and in addition having good eyesight is a major requirement for some jobs as well.

Take photographers for example. In order to take good photos you need to have excellent vision. Glasses are not always practical as you cannot put the camera right up to your eye, and yet you may not be able to see well enough without them. Depending on the type of photos a photographer takes, they may find distance or close up work harder according to their weakness of sight.

If you wanted to become a pilot your vision would have to be outstanding as well. Needless to say this job is a highly responsible and important one. If you needed to wear glasses and you broke your only pair just as you were about to take off, it wouldn’t be very convenient or safe.

Some jobs require tasks that require a specific type of sight to be good. For example if you make watches or repair jewellery for a living you will need to have excellent vision close up. Imagine trying to fix a watch if all those tiny parts appeared blurry to you!

Other examples of this include any job which involves working with computers. Good close up vision is needed for this otherwise you may suffer headaches. While a lack of good eyesight may not be a danger in a job like this, you can certainly find it harder to get on successfully if your eyesight is not perfect.

Other jobs require you to have excellent distance vision. Driving can be done with glasses or contact lenses to correct any impairment, but you must still be able to meet legal requirements with these aids if needed.

In contrast being able to see specific colours could be relevant to certain jobs. Fashion designers should be able to identify different colours and know when they look good together. Any kind of colour blindness could hamper progression in this particular field.

Some jobs have very exacting specifications you must meet in order to be considered for a position. One instance is the fire service. You might find that if you have had laser eye surgery to correct a problem, this will be good enough.

If there is a particular job you want to do it is always wise to find out whether it requires any standard of eyesight before you apply. If it does and you fall below the required standards, there is always the possibility that surgery could rectify this. You would have to find out what the options are and whether you can meet them. If you can, you could be looking at a whole new career.

Saying is easier than doing. To solve these stresses is very hard. Even as for this matter, some of us think it is possible and practical, but other think it is funny. Nowadays, it is very important for us to learn the way of solving stress, as our daily lives are full of stresses.

Now, let’s begin our process of solving stress. The first is to find out the root of our stresses. If we can not find the root, there is no solution for our stresses. There is always a solution for any problem. For example, if you can not do something in time, just set the time ahead a little. If you encounter traffic jam, try another way.

Generally, stresses come from our daily work. Too much work makes all of us felt very stresses and tired. Now, as for these matters, we should ask other people for help or expound cleanly to our bosses. All work what we do should be within our ability. If they are out of our ability, it will be very tired for us to deal with them.

The way for relaxation is very simple. First, inhale deeply. Then, relax ourselves with eyes closed for some time. Look at objects far way for some minutes in each working hour. Because vision problems will ensue if we have accumulated too much stresses.

Fearing Cataracts – Are They Dangerous

?

The eyes come with their fair share of problems and health concerns. One of the major ailments is cataracts. This happens with age; as the eye gets old the lens becomes weaker. Cataracts cause a cloudy spot on the lens or cornea and vision becomes blurry. The lens of the eye has become denser and loses the transparency it once had.

The first solution the eye doctor will give is surgery. Surgery is the only way to fix the problem; or so you have been told. They will wait until the cataract is big enough to remove with surgery. The whole left in the eye will be replaced with a plastic lens so you can see once again. This process is expensive and may only work for a short while before coming back in another area of the eye or the other eye.

The number one cause of cataracts is stress. Most people who get cataracts have gone through some seriously stressful situations or life a high stress life. They never take the time to relax and are always on the go. Another cause is a poor diet, high in cholesterol and carbohydrates and low in vitamins and fruits or vegetables.

You can reduce the risk of cataracts today by learning to relax the eyes and eating a more healthy diet. Choose foods that are high in Vitamins A-E and increase the amount of fruits and vegetables you eat. Try to live a healthy lifestyle which includes regular exercise, no smoking, and little to no alcohol consumption.

Exercise is a great way to reduce stress and mental strain. Find the time to exercise at least every 5-6 days; even a brisk walk around the block is better than nothing. Take some time for yourself and relax. Lie out in the sun after work and close your eyes for 10-15 minutes as often as possible. Move things off the ‘to do’ list that can wait and don’t require immediate attention. Learn to say ‘no’ and try not to take on more than you can handle.

Avoiding stress and strain in your life can help improve your eyesight naturally. Cataracts are caused from too much strain and living a stressful live, so do your eyes a favor and relax.

People with unhealthy cornea may have unsatisfying job performance. Their functional vision is also affected, which always can not be corrected by semi rimless glasses or rimless glasses. There are many situations that require a cornea transplant, such as infection-caused scarring, keratoconus, hereditary factors, LASIK complications, chemical burns and excessive corneal swelling. Patients should also make a proper plan, since a cornea transplant needs a recovery period of six months to a year. Before receiving the surgery, you should also ask about the cost and potential vision benefits.

Healthy corneal tissue is supplied by a local eye bank, so that the recipient must wait for a donor eye. The donor cornea’s tissues must be meticulously screened for presence of diseases. A corneal transplant will be conducted on an outpatient basis and anesthesia is often used to relax the recipient’s eye muscles. During the two-hour surgery, a round, button-shaped corneal area will be removed and replaced with a nearly identical donor tissue. The smaller size of transplantation is the lower risk to cause irregular corneal shape. The patient’s eye should be shielded to avoid rubbing.

Graft rejection may happen at a low incidence after at least one month. Those early signs of graft rejection include redness, light sensitivity, decreased vision and pain. Medications are available to reverse the rejection process. The worst case is second cornea transplantation.

Most of the people can return to work within several days after the surgery if necessary, but they should be prohibited from heavy exercise and lifting during the first weeks. Patients should also protect eyes from external objects, since their eyes are fragile during the recovery period. The doctor will probably prescribe steroid eye drops to help the patient recover. The whole recovery process can last as long as a year. For those with low healing rate, stitches may be removed after 17 months.

Since the curve of the cornea transplant can not match exactly the curve of your existing cornea, corrective glasses are needed after a cornea transplant. And your vision will be stable after the healing process is finished, after which your eyewear’s prescription can be accurately determined. Most doctors recommend RGPs for patients after a cornea transplant, since their cornea’s surface may be slightly affected.

Presbyopia is felt usually around the age of forty, even if some people do not have a problem until their early fifties. You'll find:

• to see things further away to make them – handwritten notes, sewing, newspapers.
• it hard to read in low light conditions, such as a restaurant menu in the evening.
• headaches or tired eyes after reading for long periods.

difficulty

• see small detail or to print.

Presbyopia occurs because of the aging of the lens in your eye. From birth onwards, this lens changes shape so that you relate to any distance. Over time, the flexibility and reduces the lens does not allow you to close, to see no more. You now have a prescription lens for reading and fine detail. It happens at any time, and you can not prevent, you can wise decisions, to make life easier. So, what are your options?

If you want more than one thing at once, like read and see on television, then you need glasses, with which both near and far. Vario-lenses have three powers within the lens – distance, middle distance and reading. This will be your natural vision, which allows you to anything with a smooth transition between all areas of the lens. They look like single vision lenses – nobody guessed your age!

Bifocal only one reading and distance prescription. They can cause problems because they do not have the middle distance section, it may not be used on the computer, and you can not see the dashboard while driving. The reading segment is also one of the people looking at you.

There are options to KL. Multifocal contact lenses give the same effect as variometer data. Or you can contribute by far the reading information on the target. The other option Monovision is a compromise where you have a lens in one eye corrected that your distance vision, and a reading lens in the other. Sounds strange, but your brain has to work for you! It is very well suited for suitable patients.
