Summer Food Drive

From August 18 to September 19 you have an opportunity to help us collect food donations for the Forest Food Bank again this year. Summer is quiet for donations at the Food Bank but the need is still present. During these dates, you’re invited to bring a non-perishable item when you visit our office. Peanut butter, canned vegetables, baked beans and soup are in high demand.

In exchange for a donation you can complete a bollot to win a prize. Each week we will be giving away a choice of prizes including an Eyefoods book, Eyefoods for Kids, or Baby Banz sunglasses. Thanks for helping us help the Forest Food Bank!

Online glasses and contacts

Canadians are increasingly turning to the internet to purchase products. The internet can be a “wild frontier” of unregulated trade. Websites that sell glasses and contact lenses have been operating for some time and advertise aggressively. They tend to promote low price and convenience. So is there any downside to purchasing your glasses and contact lenses online?

In Ontario, as in much of North America, the act of prescribing and dispensing contact lenses or glasses is a controlled act that must be performed by a licenced Optometrist or Ophthalmologist as dictated by the Regulated Health Professions Act. Opticians are regulated health professionals who are licensed to dispense a prescription from an Optometrist or Ophthalmologist.

Online retailers do not usually introduce you to an individual regulated health professional or allow you to meet them face to face. Most do not require proof of a valid, current prescription. Frames cannot be adequately sized or fitted and lenses cannot be adequately positioned before the eyes. Children and the elderly are particularly at risk as they may be less likely to verbalize vision problems resulting from poorly made or fitted glasses.

To ensure successful contact lens wear individuals must be properly fitted, trained and monitored. Without this, the risk of harm to the eyes is significantly increased. The wearers of contact lenses purchased online are not normally asked to submit proof of proper fitting, training and ongoing monitoring of their eye health by a regulated health professional placing them at risk of poor vision, discomfort or eye harm.

Here are some guidelines to follow when choosing where and how to fill your prescription.

  1. Meet your Optometrist or Optician face-to-face and know their name and credentials.
  2. Provide them with a physical copy of your prescription.
  3. Expect that glasses frames will be properly sized and fitted and that additional measurements will be taken for lens positioning.
  4. Plan to answer questions about your needs and lifestyle and expectations of your new eyewear.
  5. Expect to have your contact lenses properly fitted. The lenses should be assessed on the eye and you should be properly trained in their use, care and precautions. Expect more than one visit if you are a first time wearer.
  6. Your eye care professional should counsel you on the use of your eyewear and expected adaptation and limitations.
  7. Follow-up should be welcomed and is often required for adjustments, repairs and problem solving.

It makes sense to fill your prescription from your Optometrist. Your Optometrist understands your vision and already knows much about your lifestyle, needs and history. Because of this, the process of selecting, dispensing and adapting to your eyewear is streamlined and the continuity of care is maintained.

Consider your eyes. Maybe it’s more than just saving a few dollars; it’s caring for one of your most precious senses.

Colour Blindness

Did you know the human eye is capable of distinguishing up to 10 million colours?  Colour discrimination is critical to how we interact with our environment and adds beauty to our world. It is also a common language. For example, we can ask a friend “Would you hand me the red container on the self?” because we share a mutual perception for the colour red.

Colour vision perception is a complex process beginning with a structure in the eye called the retina. Within the retina are receptor cells we call rods and cones. The cone receptors correspond primarily to vision in our central visual field and are best at detecting detail and colour. There are 3 different cones types, each responding best to a certain range of light’s wavelengths. The brain processes the response of each of these cones to “triangulate” the perceived colour. The visible colour spectrum extends from violet to red.

Some people have altered colour vision perception often referred to as colour blindness or colour deficiency. There are many forms and causes of altered colour vision but I will describe two of the more common inherited causes of the so called “red-green color blindness”: dichromacy and anomalous trichromacy. Dichromacy is the more severe colour deficiency caused by the absence or malfunction of one of the 3 types of cones. Anomalous trichromacy is more common and occurs when one of the 3 cones does not function properly.

In colour blindness, the colours that cannot be perceived depend on which cone is abnormal or absent. Problems with the longer wavelength or red sensitive cone results in either protanopia (a dichromacy) or protanomaly (an anomalous trichromacy). Red light may appear gray or duller. Red and greens may be difficult to distinguish.

If the medium wavelength or green sensitive cones are affected it is called deuteranopia (a dichromacy) or deuteranomaly (an anomalous trichromacy). Green appears duller or gray and differences in hues of red, orange, yellow and green are challenging.

These colour deficiencies are called “sex-linked” because many of the genes for colour vision are located on the X chromosome. Because of this males are about 8 times more likely to inherit a red-green deficiency. The most common red-green deficiency is deuteranomaly.

Most people with colour blindness adapt well to their environment. It is important to recognize altered colour perception in children so that teaching methods can be adjusted and leeway provided for responses to colour based problems. A few occupations requiring accurate colour discrimination may be difficult or impossible to achieve. Some coloured filters, software, apps and other devices can provide some limited assistance in overcoming reduce colour discrimination.

You optometrist can test for colour vision deficiency, starting at about age five. There are some interesting online tests with links listed below. Interpret these results with caution because proper room lighting and monitor calibration with external hardware are crucial to the accuracy of the test results.

Hockey and eye protection

A true Canadian pastime is the game of hockey. In this article I am speaking to those who actually play the sport, not just watch it. Enjoyed by all ages hockey is fast paced, a great workout, a skill based team sport and is, regrettably, not without the risk of injury. I have enjoyed playing for years but always become a little nervous when playing alongside others who do not have adequate protective equipment – particularly face protection.

Basketball, field hockey, ice hockey, lacrosse, racquet sports, baseball, softball, wrestling, fencing, cricket and paintball are sports presenting the highest risk of eye injury. While face protection is mandated in most Canadian jurisdictions, adult recreational leagues, pickup hockey, and other children’s hockey groups often do not have such regulations or do not enforce them.

Eye injuries in hockey, often caused by a puck or stick, can be severe resulting in blindness or loss of an eye. This trauma is devastating to an individual resulting in reduced quality of life and increased financial burden. Fortunately, the proper use of CSA-certified eye protection drastically reduces the risk of eye injury. Full face protection is preferred as often the stick or puck will strike the face in an upward motion and can enter under a half visor. Full face protection also reduces the risk of facial lacerations and dental trauma.

Of all my protective hockey equipment, there are two or three pieces I would not go on the ice without. One of these is my face mask. I love my vision – with both eyes!

“20/20 Isn’t Everything”

“20/20 Isn’t Everything” is a new short video of particular interest to teachers and parents. The video, created by Ontario optometrists Dr. Schell and Dr. Maharaj, shows an experiment conducted with four teachers to simulate a variety of vision problems which may affect a child’s ability to learn. The teacher’s responses are revealing and insightful.

20 20 isn't everything

A child requires clear comfortable vision to learn in a classroom environment. It is thought that 80% of learning is visual. Two common misconceptions held by some parents is that if a child is able to see something small, or if they don’t complain about their vision then all should be fine.  In fact one in six children has an eye or vision problem significant enough to affect learning. Unfortunately, many children do not receive a comprehensive eye examination before they enter their school years.

Four common vision problems affecting children are myopia, hyperopia, astigmatism and binocular vision disorders. Myopia or nearsightedness blurs distance vision. This condition is the most readily understood and identified by parents.

Hyperopia or farsightedness causes a child to accommodate more than necessary to achieve clear vision. This can result in eyestrain, headaches, variable blurred vision especially at near and an inability to sustain clear focus.

Astigmatism can cause mild to significant blurring at far and near. Sometimes a child with astigmatism is able to see fairly small things if encouraged but it is not very comfortable.

Good binocular coordination of the eyes is important in sustaining comfortable vision. If the eyes are unable to comfortably maintain accurate alignment words may run together, a child may easily lose their place reading, or they may have double vision.

Of course there are other eye and vision problems that can affect learning such as anisometropia, accommodative disorders and many different eye structural anomalies or disease. A child may also have more than one disorder.

20/20, a measurement of visual acuity, is only one component of good vision. We certainly encourage parents to have their children’s eyes tested regularly beginning at the age of six months. ESEL is a great program targeting junior kindergarten students to have a comprehensive eye examination. Ensure that your child is seeing their best at school by booking a comprehensive eye examination soon.
