(NaturalNews) A number of conditions can lead to poor vision and eye health, including near-sightedness, far-sightedness, macular degeneration, presbyopia, glaucoma, astigmatism and cataracts. As we age, we become increasingly susceptible to many of those problems. However, contrary to popular mainstream dogma, such conditions can be prevented and often even successfully reversed.
The most common vision robbing eye problems are:
Hyperopia, also known as farsightedness, is a defect of vision caused by an imperfection in the eye, such as the eyeball being too short or the lens not being round enough. Hyperopia causes difficulty to focus on near objects and, in extreme cases, may result in the inability to focus on objects at any distance.
Myopia is the term for near-sightedness and is caused by a focusing defect in the eye which makes far-away objects appear to be blurred. This is due to the focus point being a bit outside the eye lens.
Presbyopia, which literally means "old eye", describes an inability to focus on close objects and is caused by loss of elasticity of the crystalline lens with advancing age.
Macular degeneration is a vision robbing disorder that increases with age. The disorder damages the center of the retina, which is called the macula, and makes it difficult to see fine details. Eventually it can result in blurring of the central vision. Notably, macular degeneration is a common problem among diabetics.
Glaucoma refers to a group of eye conditions that can lead to damage to the optic nerve, which is the nerve that carries visual information from the eye to the brain. In many instances, damage to the optic nerve comes from increased pressure in the eye, also known as intraocular pressure (IOP). There are three types of glaucoma, one of which requires immediate attention:
* Open-angle glaucoma is characterized by a gradual loss of peripheral (side) vision which is referred to as "tunnel vision". Most people have no symptoms until they begin to have vision problems. * Congenital glaucoma is characterized by cloudiness of the front of the eye, enlargement of one or both eyes, red eye, sensitivity to light and tearing. Symptoms are usually noticed when a child is only a few months old. * Angle-closure glaucoma is a serious form of glaucoma where there is sudden, severe pain in one eye. Other symptoms can include decreased or cloudy vision, nausea and vomiting, rainbow-like halos around lights, red eyes and the eye feeling swollen. The symptoms of acute-angle glaucoma may come and go at first or may become steadily worse. Note: Acute-closure Glaucoma should be treated immediately as a medical emergency or else blindness may occur within only a few days.
Astigmatism blurs your vision at all distances and it occurs when the front surface of your eye (the cornea), or the lens inside your eye, has a surface curvature that is slightly different in one direction than it is in the other. Instead of being even and smooth in all directions, eye surfaces in those who have astigmatism may have some areas that are flatter or steeper. Unlike most other eye conditions, astigmatism is often present at birth. It may also occur in combination with nearsightedness or farsightedness.
Another vision concern as we age is the formation of cataracts, which is a clouding of the eye's natural lens. It is caused by the clumping together of proteins in the eye which are normally arranged in a precise way that keeps the lens clear and lets light pass through.
In the coming installments of this six-part series we will show how good habits, eye exercises and many dietary, supplemental and herbal items can help maintain good eye health, prevent eye and vision problems and even help correct existing problems in virtually all of the above described conditions (with the noted exception of Angle-closure glaucoma).
