World Council of Optometry marks 90 years advocacy

Eyezone Blog-WOC-90th anniversary
 World Council of Optometry

Originally founded in Cologne, Germany in 1927 as the International Optical League (Ligue Internationale d’optique), The World Council of Optometry (WCO) marked its 90th anniversary on March 7, 2017.

Headquartered at the American Optometric Association offices in St. Louis, Missouri, the WCO is the only global optometric body in official relationship with the World Health Organization (WHO) and partners with many eye care organizations which share the same goal of high-quality eye health and vision care being accessible to all people.

WCO serves in the development of optometry around the world and supports optometrists in promoting eye health and vision care as a human right through advocacy, education, policy development and humanitarian outreach worldwide.

The WCO collectively represents over 200,000 optometrists in almost 60 countries through over 200 affiliates, associate, corporate and individual memberships across six world regions: Africa, Asia-Pacific, Eastern Mediterranean, Europe, Latin America and North America. Having a long history of worldwide leadership, past WCO presidents have come from countries all over the world including Australia, Canada, Germany, Hong Kong, Nigeria, Norway, the United Kingdom, South Africa, Switzerland and the United States.

“Next to life itself is the gift of vision,” WCO President Uduak Udom explained. “The beauty all around, which just amazes us, comes through vision. Most of our learning comes through vision. For these and many more reasons, optometrists around the world are committed to the cause of a world where high-quality eye health and vision care is accessible to all people.”

WCO will be hosting the 2nd World Congress of Optometry to be held in Hyderabad, India from September 11-13, 2017, in partnership with the Asia Pacific Council of Optometry (APCO) and the India Vision Institute (IVI). The central theme of the meeting, Accessible, Quality Vision and Eye Health complements the World Health Organization (WHO) Global Action Plan of Universal Eye Health with a goal of universal access to comprehensive eye care services.

Nobel Prize: Optical Legacies

eyezone-blog-nobel-prizeOct 3, 2016: Announcement of winners of the Nobel Prize 2016 kicked off in the following categories: Physiology or Medicine, Physics, Chemistry, Peace, and Economic Science. Yoshinori Ohsumi, a Japanese cell biologist, bagged the Nobel Laureate in Physiology and Medicine for his discovery of mechanisms for autophagy. While the announcements continue and as we await awardees in other categories, let’s take a glimpse of the optical industry’s major contributors to scientific development.

Allvar Gullstrand (1862-1930)

Gullstrand, a Swedish ophthalmologist, won the Nobel Prize in Physiology or Medicine in 1911 for his study and research on “the eye as a light-refracting apparatus”. He contributed to knowledge of the structure and function of the cornea, as well as, to research studies on astigmatism. He also improved corrective lenses for use after surgery for cataracts and devised the Gullstrand slit lamp, a valuable diagnostic tool that facilitates detailed study of the eye. These investigations led to a new concept called “optical images”. Gullstrand was entirely self-taught in most of his geometric and physiological optic works. His major writings on physiological optics, along with his other works, received awards in various medical institutions.

Ragnar Granit (1900-1991), Haldan Keffer Hartline (1903-1983),

and George Wald (1906-1997)

In 1967, Granit, Hartline, and Wald jointly received the Nobel Prize in Physiology or Medicine for their contribution to the study of primary physiological and chemical visual processes in the eye. Hartline studied the inhibitory interaction in and the receptor properties of the Limulus retina. Wald discovered that Vitamin A is an important component of a light-sensitive substance in the retina, called rhodopsin, which is responsible for visual impressions in the brain. On the other hand, between the 1930s to 1950s, Granit studied the electrical impulses from the retina’s cells and demonstrated the different types of cones which are sensitive to light of three different wavelengths.

David H. Hubel (1926–2013)

In 1981, Hubel, a Canadian neurophysiologist, along with the Swedish neurophysiologist, Dr. Torsten Wiesel (1924), won the Nobel Prize in Physiology or Medicine for their contribution to the study of visual perception and sensory deprivation “by measuring the electrical impulses of cells in the visual cortex”. They discovered that “vision does not develop normally if the brain fails to make connections with the eye during a critical window early in life”. The discovery played a major role in the development of systems in treating cataracts of infants in order to prevent vision impairment in its early stages. The study also lead to the development of treatment of strabismus.

Alhazen, father of modern optics

Alhazen, father of modern optics

EYEZONE-Ibn-al-haytham-father-of-modern-opticsAbū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham, known in the West asAlhazen, c. 965 – c. 1040 ce, is considered as “the father of optics and describer of vision theory”.

“He is the first medical scholar who teaches that light “does not originates from the eye but on opposite enters the eye” [sic], and in that manner corrects the wrong opinion of the Greeks about the nature of vision. According to this scholar retina is the center of vision and the impressions that it receives are transferred to the brain by the optical nerve, in order that brain afterwards create visual image in the symmetrical relationship for both retinas.”

Spectacles in historic art

 

Spectacles – eyewear, in general – had gone a long way in human history. But there are memorable ones that last thousands of years. How did these eyeglasses stood the test of time? The answer is called Art. Great artworks had become the vehicle for these spectacles for ages, and this set of artworks, whether painting or sculpture, had transported the spectacles into the current time for our generation to admire.

In March 1635, Ridhā al-‘Abbasī, a Persian artist, inspired his student, Mu’in al-Musawwer, to paint him while wearing his spectacles. The painting is said to be the oldest known artwork in the Muslim world that features the spectacles. After the 13th century, the spectacles have become famous among Muslims as the item had been featured in several literary forms and writings, as well, such as in one of the poems of Ahmad al-Attar al-Masri and in a book written by historian, al-Sakhāwī; all with relevant association with eyesight and its health corresponding to stages of youth and ageing. A painting by Ridhā al-‘Abbasī dated 1650 also features a man wearing spectacles and holding a book. The painting is now under the care of a gallery in Washington, DC.  The artwork shown in Image 1 is currently consigned at Princeton University Library in New Jersey.

The artwork shown in Image 2 is a preview from the art series titled, Shin Bijin 真美人 (True Beauties), created and produced by Yōshū Chikanobu, a prolific woodblock artist of Japan’s Meiji period. It is a collection of delicately hued portraits of a host of “modern” Japanese women who thrived in the new and changing world three decades into the Meiji era (1868-1912).  This Ukiyo-e print shows a woman seated at a table dressed in a kimono and wearing eyeglasses. From her blue-tinted spectacles to her gold ring, her merging of diverse styles in fashion, as much as her accessories, announces that she is a woman of means and expansive taste.
