With a history of 2500 years, acupuncture has long been used to improve human health. Energy in the human body flows continuously through several channels or meridians. Many people may suffer pain or disorder in certain parts, the reason of which is actually certain blockage of meridians in these parts. Acupuncture aims at removing these blockages. Commonly known as “Qi”, acupuncture uses needles to prick on those problematic points, in order to facilitate better energy flow and ease pain.
Recent studies have provided scientific support for acupuncture treatment. Several MRI brain scans have found corresponding brain responses when certain parts of the body are stimulated by acupuncture treatment. Acupuncture is painless and highly effective in treating vision problems. This traditionally Chinese treatment is always given to various parts including the foot, although its purpose is to improve eyesight.
According to Chinese acupuncture professionals, the impaired functioning of the liver is the major contributor to vision disorders. As a result, most acupuncture practitioners use needles to strengthen the liver and restore energy balance associated with the liver. In some cases, acupuncture treatment for eyesight may also focuses on the relieving of stress, depression and anxiety, because these factors are also reported to cause vision problems.
Besides visual disorders, acupuncture has also been taken to treat a lot of healthy conditions, promoting better health and preventing illness. Proven by plenty of scientific studies all over the world, acupuncture has been widely accepted by patients and recommended by many medical institutions. One of the most important advantages of acupuncture is that it can open blocked channels quickly and painlessly. A pity is that some people are afraid of being pricked with needles, which are actually very thin and quite safe.
Acupuncture treatment should be quite precise that one wrong needle may lead to major problems, so that the selection of a right therapist is quite critical. In addition, acupuncture therapists on the market have varying skills and knowledge. Patients should tell the therapist all their history of disorders before getting acupuncture sessions. An acupuncture session typically costs $60 to $120 and most patients need several sessions in total.

The history of eye frames is a part of the history of spectacles. Before the modern shape of eye frames occurred, several centuries had been gone through since the invention of the glass lenses. It was until 1928, a London optician Edward Scarlett developed the temples to the eye frame, from then a new era was opened for the contemporary eye frames industry.
Before Edward, the most recent way of holding the two lenses in eye frame was to tie the eye frame around the head using ribbon or metal string. These ancient eye frame on the nose were heavy therefore usually causing pinching. In order to reduce the weight, people started to make eye frames made of tortoise-shell, which also superstitiously meant to bring good luck to the wearers. People also mounted the lenses on the fans, walk sticks for the convenience of use. Other than nose eye frame, people could choose monocle and lorgnette or scissors glasses.
In 1728, Edward’s genius invention of temples revealed the rudiment of today’s eye frames. Actually Edward’s idea was just to use the two arms to clamp at the temple area, and ribbons were still used to tie around the skull, so that the eye frame could be secured on the face. It was by 1880, temples were designed to curve at the end and the curves were used to hook the whole eye frame on the nose.
Before Americans developed the metal eyeglass frames and spectacles trade in the early 1900s, the eye frames were mostly made in Europe and were very precious and expensive. Americans made tortoiseshell and horn-rimmed eye frames in the 1920s and 1930s, which were very popular at that time. Also in order to cater to the tastes and needs of those status conscious buyers, Americans developed and made a lot of gold and silver eye frames then. Till WWII, steel-made eye frame became popular for their fashion design and durability.
In the 20th century, a type of plastics were developed which gradually occupied the major percentage of the eye frame industry. Plastics offered the wearers with widest varieties of semi rimless designer frames in colors, styles and patterns due to its easy molding and low cost. Later the popularity of sunglasses in Hollywood further boosted the design and manufacturing of eye frames.
Today’s eye frames are already a part of the fashion accessories just the same as clothes, jewelry and shoes. Unlike our predecessors in some two hundred fifty years ago struggling to use lenses to see blurry things clearer, our eye frames are applied to enhance persona and facial beauty.

Different people should receive complete eye exams at different intervals. Children’s eyes should be examined at six months of age, three years of age, and six or seven years of age and every two years during school days, since high vision problem rates are reported among both preschool and school-aged children. For children with risk factors of vision problems such as prematurity, developmental delays, turned eyes, family history of eye diseases and history of eye injury, more frequent eye exams are necessary.
Adults at different ages need eye exams in different frequencies. Based on American Optometric Association (AOA), among people less than 40 years old, one exam every two or three years is enough for those with normal vision, while an annual exam is required for those wearing eyeglasses or contacts. People with diabetes, high blood pressure and other disorders may also require more frequent eye exams. People above 40 need eye exams every one to two years and people over 60 need annual exams, in case of age-related problems such as presbyopia, cataracts and macular degeneration.
In the United States, ophthalmologists, optometrists, as well as opticians can conduct regular eye exams. Ophthalmologists are the most professional since they are exclusively licensed to perform eye surgeries. Optometrists can prescribe certain medications and minor surgical procedures, while opticians are only entitled to adjust and repair glasses, or fit your contacts.
A basic complete eye exam should contain several items: family eye history review, distance and near vision evaluation, current eye prescription determination, eye coordination evaluation and internal and external eye healthy examination. You should be clear of all these items as well as the exact charge at the time you make an appointment with your doctor. Exam fees for contact lens fitting, laser-surgery evaluation and pediatric testing are higher than that of regular exams. You should check your vision insurance benefits for potential discount, since exam fees vary widely from discount outlets to surgical offices.
For better exam results, you need to take necessary documents and cards of yourself and your family members. Your vision insurance card is needed if you want to get any discount. For your eyes full evaluation, your major medical health care cards and recent prescription glasses or contacts may be useful to provide additional eye exam aspects. A list of your prescription medications can help the doctor learn your complete health history. Of course, you can bring your interested questions.
