CNIB-logoAbout the CNIB

CNIB is a registered charity, passionately providing community-based support, knowledge and a national
voice to ensure Canadians who are blind or partially sighted have the confidence, skills and opportunities
to fully participate in life.

To do that, our dedicated specialists work with people of all ages in their own homes, communities or
local CNIB offices - providing the personalized rehabilitation support they need to see beyond vision
loss, build their independence and lead the lives they want.

In addition to our community-based services, we also work hand-in-hand with Canadians who are blind
or partially sighted to advocate for a barrier-free society, and we strive to eliminate avoidable sight loss
with world-class research and by promoting the importance of vision health through public education.

Who we Are

Since our founding in 1918, CNIB has grown to become the primary resource for Canadians who are
blind or partially sighted, with offices in communities across the country. We're proud to help thousands
of Canadians see beyond vision loss every single day.

What we do

Vision loss is a complex issue with many underlying challenges. For that reason, our work is made up of
three pillars designed to address the challenges of vision loss from all angles - so that we're able to
provide real, sustainable help to Canadians who are blind or partially sighted.
Those pillars are: community-based support, knowledge and a national voice.

Who we serve

Any Canadian who has experienced a loss of vision, in any community nationwide, can come to CNIB for
rehabilitation support - whether you're an adult or senior; a child or teen; whether you've been
completely blind all your life or have recently experienced a partial loss of vision.

You don't have to be legally blind to come to CNIB (in fact, nine out of every 10 people we serve have
some degree of sight), and you don't need a referral of any kind.

Our history

• CNIB was founded in 1918 to serve veterans returning home blind from World War I.
• CNIB is one of Canada1s oldest charitable organizations and receives its funding through the
generous support of individuals, corporations, and other funders. Less than 35 per cent of our
funding comes from government sources.


Cirrus HD-OCT: Revealing the complete picture.

Cirrus HD-OCT offers the ultimate benefit for people livingwith glaucoma - the best possible care. Early detection helps your optometrist to diagnose and control glaucoma before permanent damage is done. If you have glaucoma or are developing glaucoma, Cirrus HD-OCT enables your optometrist to watch closely for the slightest changes and respond as needed. Cirrus HD-OCT gives your optometrist high-quality, highly accurate knowledge of your eyes that is simply unavailable with any other technology. The extremely detailed understanding of your eyes can be instrumental and essential to safeguarding your vision for many years to come.

What is glaucoma?

Glaucoma is a progressive disease of the optic nerve.

It can be associated with elevated pressure inside the eye and can lead to permanent vision loss.

There are usually no symptoms at first. As the disease progresses, a person with glaucoma may not notice his or her vision gradually failing.

Your optometrist can use a highly innovative instrument called Cirrus™ HD-OCT. This
advanced-technology instrument never touches your eye, so there’s no discomfort. It’s safe and requires only a few minutes. Most importantly, the Cirrus HD-OCT helps your optometrist to clearly see the internal structures of your eye, so problems can be treated before they progress. The unique view that your optometrist sees with Cirrus HD-OCT is called a direct cross-sectional image of your retina.

What is direct cross-sectional retinal imaging?

The retina is the innermost lining of the inside of your eye. It is composed of several layers, and functions like the film in a camera. The lens of the eye focuses images on your retina, much like the lens of a camera focuses images on film. These images are transmitted to your brain by the optic nerve, enabling you to see.

Direct cross-sectional imaging enables your optometrist to look directly at a “cutaway” view of the layers of the retina and optic nerve, and accurately measure their characteristics. Other machines show the surface of these structures, but Cirrus HD-OCT also shows your optometrist what is below the surface.

What does direct cross-sectional retinal imaging offer that’s unique?

With Cirrus HD-OCT’s ability to image the individual layers of retina, your optometrist can see and measure delicate structures and monitor any changes. OCT imaging is the only technology that provides these cross sectional images, so it’s the ultimate tool for precise diagnosis and treatment.

What can direct cross-sectional imaging tell my optometrist about glaucoma?

Cirrus HD-OCT enables your optometrist to perform multiple analyses for glaucoma. The three most common tests are:

  • Retinal Nerve Fibre Layer (RNFL) Analysis reveals the thickness of the layer of the retina that contains nerve fibres that travel up the optic nerve. If glaucoma is present, that layer may gradually lose thickness.
  • Macular Thickness Analysis examines the condition and thickness of the macula, which is the part of the retina that provides central vision. Thinning of the macula is a possible sign of glaucoma progression.
  • Optic Nerve Head Analysis reveals the structure of the optic nerve where it originates in the retina. With glaucoma, the “cup” in the optic nerve may enlarge.

Annual eye exams are vital to maintaining your vision and overall health. Our Health Plus Family Vision Care office now offers the optomap® Retinal Exam as an important part of our eye exams. The optomap® Retinal Exam produces an image that is as unique as your fingerprint and provides the doctors with a wide view to look at the health of your retina. The retina is the part of your eye that captures the image of what you are looking at, similar to film in a camera.


Children's vision care is essential to every child's development. Experts say that over 80 percent of what a child learns in school is presented visually, so making sure your son or daughter has good vision can make a big difference in their academic performance.

Routine eye exams for children can detect any nearsightedness, farsightedness and/or astigmatism your child has so it can be promptly treated with eyeglasses or contact lenses. Routine exams are also needed to make sure your child's eyes are healthy and to rule out amblyopia, strabismus and other binocular vision problems that may interfere with your child's vision development, academic performance and sports vision.

As a parent, you may wonder whether your preschooler has a vision problem or when you should schedule your child's first eye exam.


The Potential Pitfalls of Shopping for Spectacles Online

The Internet has fast become one of the most influential global forces. While it has helped open people up to amazing opportunities throughout the world, it has also demonstrated similarities to Pandora's Box. Some things are better left unopened; or at least reserved for a trained professional to open. This is especially true of the burgeoning online health and medical industry. Specifically, online consumers and Internet shoppers now have virtually unfiltered, unrestricted access to prescription spectacles with a critical gap in safety standards and compliance regulations. Because of this, we'd like to highlight the following study's investigative observations: Safety and Compliance of Prescription Spectacles Ordered by the Public via the Internet (The authors of the study are: Karl Citek, O.D., Ph.D., Daniel L. Torgersen, MBA, MS, Jeffrey D. Endres, ABOC, and Robert R. Rosenberg, O.D.).

This study explores the process of ordering prescription glasses through Internet vendors as well as the actual delivery of these items to public consumers, primarily measuring compliance with the optical tolerance and impact resistance requirements for eyewear dispensed in the United States.

In total, 200 eyewear orders were purchased through online vendors by 10 different participants in the study. The orders were evenly divided to account for important variables such as lens and frame materials, lens styles, and refractive corrections. Ten individuals ordered 2 pairs of spectacles from each of the top 12 highest traffic-ranking spectacle-vendor websites in order to best replicate the average consumer experience for online spectacle shopping.


 

Stats…
According to the Canadian Diabetes Association:

  • More than 9 million Canadians are living with diabetes or prediabetes
  • Diabetic retinopathy (the detrimental effect diabetes can have on the eyes and vision) affects 23% of people with type 1 diabetes and 14% of people with type 2 diabetes on insulin therapy.

Our sun emits light at many different wavelengths, making up the electromagnetic spectrum. The electromagnetic spectrum encompasses light from high wavelength/low energy radio waves to low wavelength/high energy gamma rays (see diagram). Only a small portion of the electromagnetic spectrum is responsible for our sense of sight. This portion is known as visible light and ranges from 760-780 nm (red) to 380-400 nm (violet). Ultraviolet (UV) light falls in the range of 10-400 nm and is therefore not visible to the human eye. Since UV light has a shorter wavelength than visible light, it will have more energy (higher frequency) and thus penetrate objects more readily. When excess amounts of UV light penetrate the human skin and also the human eye, structural damage can result.


Do you struggle with needlework and crossword puzzles?

Do you feel your arms just aren’t long enough anymore?

If you answered “yes” to any of these questions, then you may be experiencing normal, age-related loss of near focusing ability — which is known as Presbyopia.


Why not try contact lenses!

With the winter season in full swing, having to wear glasses may get in the way of some of your favourite winter sports. If your glasses fog up while skiing or make your hockey game more difficult, contact lenses could be the solution.


Diabetes occurs when the body does not produce enough of the hormone insulin, leading to excess sugar (glucose) in the bloodstream. Diabetes can affect many parts of the body, including the eyes. The high levels of glucose in the blood can cause the tiny blood vessels in the retina to weaken and leak, leading to a condition known as diabetic retinopathy.
