Colour Deficiency

The human eye only sees three colours: red, blue and green. All other colours are a combination of these. However, some people can't see these colours at all! When this happens, its called colour deficiency.


What is colour deficiency?
Colour deficiency occurs when your ability to distinguish colours and shades is different than normal. The term “colour blind” is often used, but usually incorrectly. Only a very small number of people are completely unable to identify any colours, a condition called achromatopsia. Colour deficiency is more common in males than females, with one in 10 males having a colour deficiency.
What causes colour deficiency?
Colour deficiency is usually an inherited condition, passed from mother to son, but it can also result from certain diseases, trauma or as a side effect of certain medications. Colour deficiency is the result of an imbalance in the three kinds of cones in the retina that allow us to perceive colour.
What types of colour deficiency exist?
There are three types of colour deficiency: two different kinds of red-green deficiency and one called blue-yellow deficiency. The red-green deficiencies are by far the most common and are usually inherited, resulting in the inability to distinguish between certain shades of reds, browns, pinks and oranges, or greens and blues. Blue-yellow deficiency is very rare and is usually acquired secondary to damage to the optic nerve and results in the inability to distinguish between certain shades of blue, as well as shades of yellow. People with complete colour blindness see objects in shades of black, white and grey.
How is colour deficiency detected?
Children who are colour deficient are generally unaware of their condition. They assume that everyone sees things the way they do. As a result, a complete optometric examination, including a test for colour vision, is recommended for every child. The test for colour deficiency is a relatively simple one, typically involving the viewing of a series of coloured plates with numbers or designs. The plates have been created in such a way that a person with normal colour vision can see certain figures in the designs. A person with a colour deficiency will either see a different number of designs or will be unable to distinguish the figures.
When should a person be tested for colour deficiency?
Every child should be checked for colour deficiency by at least age five. It is important to detect colour deficiency early because colour coded learning materials are used extensively in the primary grades. In addition, colour deficiency may affect the career path of an individual, since the ability to distinguish colours is an important aspect of some jobs, such as pilots, electricians, some military personnel, police officers and others.
Can colour deficiency be cured?
Unfortunately, a cure for colour deficiency has not yet been discovered. A person with a colour deficiency can, however, be taught proper colour naming and to accurately distinguish colours. For example, you can be taught to recognize the brightness and location of a traffic light rather than the colour itself. It is sometimes possible to increase the ability to distinguish colours with the use of special filters. For example, a special red tinted contact lens can be used in one eye, to aid people with certain colour deficiencies.

Are you experiencing blurred vision and headaches?

Blurred vision & headaches may be caused by a naturally occurring aging process called "presbyopia."

Having to wear glasses for the first time due to presbyopia turns out to be a natural part of aging for most of us. But the stress and anxiety experienced by one woman while trying to have its symptoms diagnosed is not.

“A Doctor of Optometry in our office saw a female patient who had disabling headaches and blurred vision,” says Doctor of Optometry Richard Kort. “She first went to a family physician, who ordered a series of tests, including a CAT scan, to rule out a brain tumor or aneurysm. Months later she came into our office for a comprehensive eye exam. A simple pair of reading glasses got rid of her symptoms. But the entire process took months and seriously affected her quality of life.”

Dr. Kort says the unnecessary anxiety the patient experienced drives home the importance of seeing a Doctor of Optometry if you are experiencing blurred vision or headaches – symptoms that can be related to vision problems, such as presbyopia (literally “aging eye” in Greek). Doctors recommend that adults under age 65 have a comprehensive eye exam every two years, and seniors annually.

Other symptoms of presbyopia include eye fatigue, difficulty reading in dim light, and having to hold reading material at arm’s length. People with a history of good vision are typically the most surprised when symptoms of this naturally occurring process begin, usually around the age of 40.

But while eyeglasses are an inevitable fact of life for most of us, not all glasses are created equal. Buying “cheater” lenses – the inexpensive glasses often purchased in drug stores without a proper prescription – may be tempting, but other factors need to be considered for proper vision care. Cheaters don’t take into account the wearer’s preferred reading position and angle, or that most people need different magnification strengths for each eye to avoid eye strain and fatigue.

“Using cheaters may reduce the amount of time someone can read comfortably, compared with prescription reading glasses,” says Dr. Kort.“Prescription reading glasses don’t have to be expensive. The important thing is that, if you’re having difficulty reading, you should see a Doctor of Optometry.”

Eye exams need to be regular:

  • Children should have their first complete eye exam between six and nine months of age, another between ages 2 and 5, and yearly after they start school.
  • Adults 20-39 years old should have an eye exam every two to three years.
  • Adults 40-64 years old should have an eye exam every two years.
  • Those over age 65 or people with diabetes or a history of eye disease in their family should have yearly exams, or as recommended by a Doctor of Optometry.

Routine eye exams by a Doctor of Optometry not only ensure good vision and eye health, but peace of mind. For more information or to book an appointment, please call us at 604.553.3900 or visit us online at www.visionsourcenw.com.

A Historical Look at Women in the Eyecare Professional Community


September is Women of Achievement Month so we thought it would be appropriate to take a look at the women who made history in the eyecare professional community. We would like to introduce you to some notable women, we think you should know about, in the eyecare industry.
Women in Ophthalmology
Patricia Bath is the first African-American female physician to receive a patent for a medical invention. Inventions relate to cataract surgery and include the Laserphaco Probe, which revolutionized the industry in the 1980s, and an ultrasound technique for treatment. Bath also co-founded the American Institute for the Prevention of Blindness (1976) whose motto is “protect, preserve, and restore the gift of sight.”
Selwa Al-Hazzaa published many papers, but her most important paper was DUANES, which specialized in genetically inherited eye diseases in Saudi Arabia. In 1997, she became the first female department head in King Faisal Specialist Hospital, as she became the head of the ophthalmology department. She was also the late King Fahad’s personal ophthalmologist.
Ida Mann diagnosed a trachoma epidemic amongst Indigenous people in the Kimberleys and traveled extensively in Western Australia in order to examine and treat Indigenous people with trachoma. Mann published extensively in the area of eye anatomy and eye disease, publishing many scientific articles and several books. She also wrote on her travels and findings relating to trachoma. Most of her writings were published under her married name Ida Gye or a pseudonym, Caroline Gye.
Marilyn Miller is an American pediatric ophthalmologist specializing in the diagnosis and treatment of congenital eye diseases and strabismus. She has held leadership positions in her field, often as the first female in those positions. She was the first female to serve as president of the American Association for Pediatric Ophthalmology and Strabismus, and also the first female board member of the American Academy of Ophthalmology.
Aida de Acosta Root Breckinridge became an advocate for improved eye care and was founder and director of the first eye bank in America, after losing sight in one of her eyes to glaucoma, in 1922. Her ophthalmologist was famed eye specialist William H. Wilmer, whom Time magazine called “the greatest eye surgeon the U.S. has ever had.” Dr. Wilmer’s care saved her other eye, and inspired her to organize a fund-raising campaign that resulted in $3 million to fund the establishment in 1925 of the Wilmer Eye Institute in Johns Hopkins Hospital, the first eye institute in the U.S. In 1945 she founded and became Executive Director of the Eye-Bank for Sight Restoration in New York, the first eye bank in the U.S
Isabel Hayes Chapin Barrows (1845–1913) was the first woman to practice ophthalmology in the United States, as well as the first woman appointed to a medical school faculty. Her accomplishments, she managed while financing her husband’s education and raising two children. Her list of achievements also includes serving in roles such as a missionary, editor, reporter, prison reformer and ambassador.
Regina Salomea Pilsztynowa, ophthalmologist in 18th-century Poland. Regina Salomea Rusiecki (later Pilsztynowa) was a young, poorly educated Polish Catholic woman in the 18th century who became well known in Eastern Europe and the Ottoman Empire because of her skill in the treatment of cataracts and some other medical problems. She was born in 1718, and at the age of 14 she married an experienced, but significantly older, German Lutheran physician and ophthalmologist, Jakob Halpir. By helping him eagerly in his work, Pilsztynowa learned a great deal of her husband’s way of treating cataracts and other ailments, and she ambitiously made use of the friendship and help of other physicians whom she met on her travels.
Else Steinert née Loewenheim is one of Germany’s first female specialist ophthalmologists. Merely tolerated as a guest listener, she conducted most of her studies in Leipzig (1900-1905) and acquired her doctor’s license there. During World War I she worked as assistant at the Ophthalmology Clinic at Leipzig University under Hubert Sattler (1844-1928), but soon thereafter was displaced by her male colleagues returning from the War. Between 1920 and 1937 the young widow and mother of three had a private practice, first in Leipzig and then in Idar-Oberstein, which was one of the first ophthalmology practices to be opened by a female doctor on a national scale. After the Nazis had seized power and she had thus been declared a Jew, her doctor’s license was withdrawn and in this manner she was deprived of her livelihood. To escape being deported to a concentration camp she fled and survived World War II in the countryside of Bavaria. Her MD thesis of 1920, of which only an eight-page abridged version has survived, is a contribution to the debate on the indication and prognosis of Elliot’s trepanation for the treatment of glaucoma. Based on her investigations she strongly recommended this operation for all patients with severe glaucoma.
Dr Georgiana Dvorak-Theobold was the first woman to win the Howe Medal in 1957 for her contributions to the ophthalmic world. She made many contributions to our understanding of ocular disease. Most importantly, three particular areas, the anatomy of the canal of Schlemm and its relation to the vascular system, the second is the pseudo-exfoliation of the lens capsule, the third area was the possible location of abnormal resistance to aqueous outflow in the collector channels. She joined the Illinois Eye and Ear Infirmary in 1915; she remained affiliated with them for her entire life. The American Board of Ophthalmology certified her in 1928; she became a full member in 1934.
Women in Optometry
Celia Sánchez-Ramos gained her PhD in Pharmacy in the area of Preventice Medicine in 1994. She is a well-established optician-optometrist and Tenure Lecturer at the Universidad Complutense de Madrid. She has filed 13 patents, including one for therapeutic contact lenses for pseudophakic eyes and/or eyes suffering neurodegeneration. The latter innovation led to her being awarded, in April 2009, the Best Invention presented by a Woman Inventor of 2009 prize (Premio a la Mejor Inventora del Año 2009) by the UN World Intellectual Property Organization, the Gold Medal (with congratulations of the jury) for the Best Invention in the Healthcare Area, and the Best Spanish Patent prize, awarded by the Spanish Office of Patents and Trademarks (Oficina Española de Patentes y Marcas).
Paula R. Newsome is the first African-American female Optometrist to practice in North Carolina, and the second African-American female Optometrist licensed by North Carolina. She is the first African American female in the U.S. to become a member of the American Academy of Optometry.
Mollie Wright Armstrong, she was the first woman optometrist in the state of Texas and only the second in the United States. After attending Baylor Female College, she studied at optometry schools in Georgia, Illinois, and Missouri. She began her practice in Brownwood in 1899. She was active in the passage of the first optometry law in Texas, became a member of the Texas Board of Examiners in Optometry, and served as vice president and president of the board, to which she belonged for twenty-four years. She was president of the Texas Optometric Association from 1923 to 1925 and at another time served as the association’s director of publicity. When the Texas Optometrist was first published, she was its editor. It was largely through her efforts that the first optometric professional liability policy was made available to optometrists nationwide, and she became a trustee of the American Optometric Association. In 1927, Dr. Armstrong was instrumental in organizing the Texas Woman’s Auxiliary to the American Optometric Association. That same year she was appointed a regional director of the American Optometric Association Auxiliary. In Brownwood, she was the organizer and first president of the American Legion Auxiliary, the Brownwood Business and Professional Women’s Club, and the Brownwood Civic League. She served as director of the Brownwood Chamber of Commerce and represented her district as a member of the State Democratic Executive Committee.
One of these two notable ladies, Fannie Gassett of Boston, MA and Gertrude M. Martin of Utica, New York are presumed to have the distinction of being the first woman optometrist in the American Academy of Optometry. Both ladies were on lists dating back to 1929, though the first published list of the American Academy of Optometry members is a geographical directory, which was first published in 1934. It is assumed, that since both women were on earlier unpublished lists that they were also among the earliest members of the Academy.
If you would like to know more about women in the eyecare professional community, please visit the Facebook pages and/or websites below. Both groups work tirelessly for women in our industry.

8 Foods to Eat for Healthier Eyes


Perceiving the world in colors, shapes, and movement is a gift most take for granted. Until the day one’s vision begins to cloud over, lose clarity, or fade away completely, such an incredible sense is easily relied upon… and therefore is devastating when lost.
But developing cataracts, macular degeneration, dryness of the eyes, or any other eye concerns isn’t inevitable. Poor diet and less than optimal lifestyle choices contribute to the rapidly increasing diseases of the modern age, loss of eyesight being one of them.
And it is now clear that by adopting a healthier regimen and eating a plethora of nutrient-rich foods, healing of the eyes is possible. In fact, some of the most beneficial foods for support healthy eyesight follow. Bursting with enzymes, minerals, and nutrients, they are nature’s perfect offerings that can help regenerate the body and heal the eyes.
Along with removing processed, refined, and chemically-treated foods from your diet, consuming more of these foods will likely assist you in attaining better eye health in no time!

BILBERRIES

This fruit contains compounds which boost visual acuity and improve vision. In Italy, a study found that a mixture of these compounds called anthyocyanides, along with Vitamin E stopped the progression of cataract formation in over 95% of study subjects experiencing early-stage progression of this disease. But its secrets are not only now becoming known: British pilots back in World War 1 knew they were incredibly beneficial for the eyes, and consumed bilberries before flying. Tasty fruits with similar compounds that improve vision include blueberry, cranberry, blackberry, grape, raspberry, and wild cherry.

CARROTS

One normally associates carrots with improved vision, but likely doesn’t know the range of benefits they offer. The carotenoids in carrots (which give it its distinct color) help prevent cataracts, prevent cancer, and reduce one’s risk of developing cardiovascular ailments. Other great sources of carotenoids include leafy greens, and fruits and vegetables that are orange, yellow, or red in color.

ONIONS

Being an excellent source of quercetin, a compound research has linked to prevention of cataracts in diabetics, onions are an extremely beneficial food to consume to heal the eyes. However, as most of the quercetin is found in the skin, it may be optimal to cook this portion of the onion as well when preparing meals.

PURSLANE

The world’s richest source of Omega-3 fatty acids, purslane boasts a bounty of health benefits essential for supporting clear eyesight. It is rich in carotenoids, vitamin C, vitamin E, and many antioxidants (including glutathione), which are all necessary for keeping the eyes healthy.

GLUTATHIONE

This compound is actually found in high concentrations in the lens of the eye, where it plays an important role in keeping it healthy. Glutathione functions as an antioxidant, maintains the structure of the lens proteins, plays a role in various enzyme systems, and can also take part in the transport of amino acids and minerals.
However, modern-day ways of living have created a lack of this essential compound. As stated by optometrist and licensed acupuncturist, Marc Grossman, OD, “The majority of the cataracts I see are low in the antioxidant glutathione.”
Thankfully it’s easy to get more: This powerful compound is found abundantly in raw fruits and vegetables, therefore eating more living foods will help it be restored.

TURMERIC

This anti-inflammatory root contains a large amount of carotenoids and vitamin C. It also shares carotenoids, vitamin C, vitamin E, and anti-oxidants.

BRAZIL NUTS

Brazil nuts are rich in vitamin E and selenium – both nutrients which help to prevent and inhibit cataracts.

SPINACH

Popeye was onto something! Spinach offers a bounty of lutein, which is known to help promote healthy vision and prevent other diseases of the eyes. This green is also rich in carotenoids and helps protect against cancer.
Diverting from natural law – eating wholesome, unprocessed food, getting plenty of rest, being outdoors, enjoying your life – results in a plethora of health issues. Thankfully nature offers many beneficial foods (and opportunities) to remedy diseases of affluence and heal.
If you seek to better your eyesight while safeguarding your future health, take action today by making more conscious dietary and lifestyle choices and visiting a Doctor of Optometry! If you have any questions, please call us at 604.553.3900 or visit us online at www.visionsourecenw.com.

Eye Health & Exam Frequency – School-age children

A school-age child’s eyes are constantly in use in the classroom and at play. For school-age children, several different visual skills must work together so they can see and understand clearly.


If any of these visual skills are lacking or impaired, your child will need to work harder and may develop headaches or fatigue. Often the increased visual demands of schoolwork can make greater demands on a child’s visual skills, pointing out a vision problem that was not apparent before school. The child may not realize they have a vision problem – they may simply assume everyone sees the way they do. A vision-related problem may cause some of the symptoms described below:
  • headaches or irritability
  • avoidance of near or distance work
  • covering or rubbing of the eyes
  • tilting of the head or unusual posture
  • using a finger to maintain place while reading
  • losing place while reading
  • omitting or confusing words when reading
  • performing below their potential
Conditions that may emerge during this stage in your child’s life include myopia or nearsightedness (blurred vision when seeing objects at a distance), hyperopia or farsightedness (blurred vision when seeing objects up close) and astigmatism (distorted vision at all distances).
Protect your child’s vision. If you notice any of these symptoms, book an eye exam with a Doctor of Optometry. Your child should have a complete optometric eye exam at six months, before starting kindergarten, and annually throughout the school years to ensure optimal eye health and developmental progress.
