A nearsighted person sees near objects clearly, while objects in the distance are blurred. Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak.

Farsightedness develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision. This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens.

The American Optometric Association reports that nearly 30 percent of the U.S. population is affected by nearsightedness and about 60 percent of Americans are affected by farsightedness.

Farsightedness, or hyperopia, affects 5% to 10% of Americans. People who are farsighted can see objects that are far away but have trouble focusing on close things. You may have blurry vision, get headaches or squint a lot.

If your cornea or lens isn’t evenly and smoothly curved, light rays aren’t refracted properly, and you have a refractive error. Farsightedness occurs when your eyeball is shorter than normal or your cornea is curved too little. The effect is the opposite of nearsightedness.

Long sight can be corrected by glasses or contact lenses, or sometimes ‘cured’ with laser eye surgery.

There are no specific remedies that are proven to improve your vision and eyesight naturally without corrective eyewear if you suffer from astigmatism, nearsightedness (myopia), or farsightedness (hyperopia).

Lifestyle and home remedies

1. Have your eyes checked. Do this regularly even if you see well.
2. Control chronic health conditions.
3. Protect your eyes from the sun.
4. Prevent eye injuries.
5. Eat healthy foods.
6. Don’t smoke.
7. Use the right corrective lenses.
8. Use good lighting.

If you think that you are reading better lately without your glasses on, see your optometrist or ophthalmologist. If your near vision is suddenly better than ever, chances are that your distance vision may be worse. Sometimes, when second sight occurs, what is really going on is that you are becoming a bit nearsighted.

After you pass the milestone age of 40, you’ll notice it’s more difficult to focus on objects up close. This is because the lens inside the eye begins to lose its ability to change shape — a process called presbyopia.

Yes, wearing glasses does improve eyesight–but only while you’re wearing them. For instance, if you have 20/70 to 20/160 vision while wearing glasses, you might have low vision, which may require extra steps or special lenses to improve your eyesight. …

Many cases of blurry or cloudy vision are caused by nearsightedness, farsightedness or astigmatism – common issues that are typically corrected with glasses or Lasik surgery. However, your changing vision could be an important early symptom of a more serious disease or medical condition.

If your body is dehydrated, this part of the tear film may be deficient. As a result, the surface of your eyes could have irritation and breakdown, which can result in blurry vision.

Seek immediate medical care for sudden blurred vision — even if your blurred vision is temporary — since such vision changes can signal a serious underlying medical condition.

Strokes don’t only happen in the brain. They can also happen in the eyes. This type of stroke is called retinal artery occlusion. Blood vessels carry vital nutrients and oxygen to every part of your body.

High Blood Pressure Patients with high blood pressure can have unusual bends, kinks or tears in the vessels in their eyes. These are typically visible during a dilated eye exam, and can help to give a clear picture of your risk of stroke, aneurysm or other complications.

Common Eye Disorders and Diseases

• Refractive Errors.
• Age-Related Macular Degeneration.
• Cataract.
• Diabetic Retinopathy.
• Glaucoma.
• Amblyopia.
• Strabismus.

Ophthalmoscopy is an exam eye doctors use to look into your eyes and evaluate their health. With this exam, your eye doctor can see the retina (which senses light and images), the optic disk (where the optic nerve takes the information to the brain) and blood vessels.

If it’s suspected you’re experiencing a stroke, a CT scan is usually able to show whether you have had an ischaemic stroke or a haemorrhagic stroke. It’s generally quicker than an MRI scan and can mean you’re able to receive appropriate treatment sooner.

Because treatment depends on the type of stroke, your doctor may use head CT or head MRI to help diagnose your condition. Other tests may include blood tests, electrocardiogram (ECG or EKG), carotid ultrasound, echocardiography or cerebral angiography.

– Warning signs of an ischemic stroke may be evident as early as seven days before an attack and require urgent treatment to prevent serious damage to the brain, according to a study of stroke patients published in the March 8, 2005 issue of Neurology, the scientific journal of the American Academy of Neurology.
