Clear vision: Two principles for eye rejuvenation



Oriental Medicine teaches us that the opening of the liver channel is in the corner of the eyes. The liver channel runs vertically from the bottom to the top of the body and opens in the eyes. Whatever effects the liver also directly effects the eyes.

The subtler functions of the liver root deeply into our emotional and psychic energies and thus the liver and our eyesight are impacted by excessive emotional stress. Any inflammation localized in the liver channel will cause inflammation of the eyes.

Therefore when we rejuvenate the liver, we directly promote the health of our eyes. The liver has a tremendous capability to rejuvenate itself. A healthy liver is soft and open. This softness permits the free flow of blood and energy to flow throughout the body directly to the eyes. A healthy liver keeps the blood clean and pure and thus directly improves eyesight. It is actually quite easy to rejuvenate the liver and thus rejuvenate our eyes.

As always, right diet is the foundation of all rejuvenation regimes. Raw organic greens which cleanse the blood and eliminate liver inflammation, should be used liberally And yes, carrots are good for the eyes so do enjoy your carrots. Beta carotene, one of the active ingredients in carrots, is also present in fresh green vegetable juices as well as green powder mixes. Along with beautiful fresh vegetables and grasses often found in green drink powder mixes, nature also provides an abundance of liver regenerating herbs such as burdock, taraxacum, barberry, scute, nettles, and more. Many of these herbs and grasses are combined into single liver cleansing products and they are effective and easy to use. There is tremendous healing potential contained in the synergy between the liver and these healing herbs. Consistent consumption of green plants and healing herbs promote eye health and contribute to our overall sense of well-being.

Do not let your eyes dry out
To function optimally the eyes require an abundance of blood and yin essences. Deficiencies in the blood and yin essences will be reflected in the eyes. Dry eyes are a common symptom of aging and quite unnecessary in many cases. If we learn to properly refresh and maintain those essences we will optimize eye health . Many of the western herbs for the eyes such as eyebright and goldenseal are very effective in their ability to clear inflammation from the liver channel. Chinese herbs such as rehmannia and lycium also promote eye health by refreshing and maintaining the blood as well as the essence that circulates to the eyes. As we age, these herbs should become a regular part of our wellness regime.

The classic Chinese formula Ming Mu Di Huang Tang or Rehmannia and Lycium Combination has been used for years to refresh the blood and essence that support the eyes. www.traditionalbotanicalmedicine.co...

Practitioners of Oriental Medicine in the United States report that the formula improves eye health and vision in almost everyone who commits to using it. There are many modern variations on this traditional formula available today in health food stores, herbs shops and online. Goji berries are one of the traditional remedies for eye problems including dry eye, so yes, eat your goji berries as well as your carrots and greens.

Black eye

Black eye introduction

A black eye often results from injury to the face or the head, and is caused when blood and other fluids collect in the space around the eye. Swelling and dark discoloration result in a "black eye" – sometimes called a "shiner."

Most black eyes are relatively minor injuries. Many heal on their own in a few days, but they may signify a more serious injury.

Despite the name, "black eye," the eye itself is not usually injured. The tissues around the eye may be significantly discolored and swollen without any injury to the eye itself, like a bruise (ecchymosis) around the eye.


The skin around the eye is very loose, with mostly fat underneath it and fluid accumulates easily in this area. The skin around the eye is one of the first places to swell when the facial area is injured. Depending on the location and type of injury, one or both eyes may be affected. Injuries to the eye brow and forehead area often result in black eyes because gravity pulls the blood and inflammatory fluid into the soft tissues under and around the eyes.

As a black eye heals, the swelling around the eye decreases, and the bruise gradually fades away. The bruising will usually start out a very dark purple, and as it fades, it may change to light purple, then greenish, then yellow before disappearing.

What causes a black eye?

The most common cause of a black eye is a blow to the eye, nose, or forehead. Depending on where the blow lands, one or both eyes may be affected.

A blow to the nose often causes both eyes to swell because the swelling from the nasal injury causes fluid to collect in the loose tissues of the eyelids.

Other causes of black eye include:

surgical procedures to the face, such as a facelift, jaw surgery, or nose surgery;

a certain type of head injury, called a basilar skull fracture, causes both eyes to swell and blacken; this condition is typically described as "raccoon eyes;"

Other causes of swelling around the eye include (these conditions do not make the skin turn black and blue around the eye):

allergic reactions,

bites,

cellulitis (skin infection around the eye),

angioedema (swelling, usually around both eyes), and

dental infections.

Retinal Disorders

The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. In the center of this nerve tissue is the macula. It provides the sharp, central vision needed for reading, driving and seeing fine detail.

Retinal disorders affect this vital tissue. They can affect your vision, and some can be serious enough to cause blindness. Examples are

Retinal detachment - a medical emergency, when the retina is pulled away from the back of the eye
Macular pucker - scar tissue on the macula
Macular hole - a small break in the macula that usually happens to people over 60
Floaters - cobwebs or specks in your field of vision

US Task Force Issues Updated Statement on Visual Screening in Young Children

The 2004 US Preventive Services Task Force (USPSTF) statement about screening for visual impairment in children 1 to 5 years old has been updated and published online January 31 in Pediatrics.

The USPSTF now recommends vision screening for all children at least once between the ages of 3 and 5 years, to detect the presence of amblyopia ("lazy eye") or its risk factors. The USPSTF concluded that the current evidence is insufficient to assess the balance of benefits and harms of vision screening for children less than 3 years of age.

In developing its updated recommendations, the USPSTF considered evidence from a review of the association of screening for visual impairment in children 1 to 5 years old with improved health outcomes, the accuracy of risk factor evaluation and screening tests, the efficacy of early detection and intervention, the potential harms of screening and treatment, and the net benefit of screening in this population. The USPSTF also realized the need for clinical or policy decisions to be based on additional considerations. Therefore, they recommend that clinicians and policy makers tailor their decisions to the specific patient or situation.

The authors noted that approximately 2% to 4% of preschool-aged children have amblyopia, an alteration in the visual neural pathway in the developing brain that can lead to permanent vision loss in the affected eye. Amblyopia usually occurs unilaterally but can occur bilaterally. Identification of vision impairment before school entry could help identify children who may benefit from early interventions to correct or to improve vision.

On the basis of the evidence, the USPSTF concluded with moderate certainty that screening for visual impairment in children ages 3 to 5 years had a moderate net benefit.

Screening tests that can be used in primary care to identify visual impairment in children include visual acuity tests, stereoacuity tests (depth perception), and ocular alignment tests. Also potentially useful are autorefractors, or automated optical instruments that detect refractive errors and photoscreeners, or instruments that detect risk factors for amblyopia and refractive errors (the need for a glasses prescription).

Evidence was adequate that vision screening tools are reasonably accurate in the detection of visual impairment, including refractive errors, strabismus (ocular misalignment), and amblyopia, and that early treatment for amblyopia for children 3 to 5 years old is associated with improved visual outcomes. Treatment for amblyopia includes patching the better eye and the use of dilating eye drops. For children younger than 3 years, however, evidence was inadequate that early treatment of amblyopia results in better visual outcomes.

Newer technologies now allow the identification of amblyopia risk factors before strabismus and amblyopia develop and become entrenched, and evidence supports the effectiveness of treatment of children so identified.

Eye Wear

Also called: Contact lenses, Eyeglasses




Eye wear protects or corrects your vision. Examples are sunglasses, safety goggles, glasses and contact lenses. If you need corrective lenses, you may be able to choose between contacts or glasses. Either usually requires a prescription. Almost anyone can wear glasses. Contact lenses require more careful handling.

Many jobs and some sports carry a risk of eye injury. Thousands of children and adults get eye injuries every year. Most are preventable with proper eye protection. Everyone is at risk for eye damage from the sun year-round. It's important to regularly use sunglasses that block out at least 99 percent of UV rays.

Eye Diseases

Eyeglasses, prescription eye glasses, rimless glasses, sunglasses, glasses, goggles & contact lenses by brand name designers at low prices online by Eye care glasses online.com

Some eye problems are minor and fleeting. But some lead to a permanent loss of vision. Common eye problems include

Cataracts- clouded lenses
Glaucoma - damage to the optic nerve from too much pressure in the eye
Retinal disorders - problems with the nerve layer at the back of the eye
Conjunctivitis - an infection also known as pinkeye

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision or everything looks dim or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye and inflammation.
