Age-related macular degeneration (AMD) is the leading cause of blindness in people over 55 in Canada and the U.S.

The Age-Related Eye Disease Study (AREDS) was a very large study sponsored by the U.S. Federal Government's National Eye Institute. The results were published in 2001.

The AREDS2 study took place after the original AREDS study and concluded in 2014. These two studies were used to design vitamin/mineral supplements to slow the progression of AMD.

The researchers concluded that taking the AREDS formulation can reduce the risk of developing a more advanced form of AMD by about 25%.

It has more recently been determined that roughly half the patients taking the AREDS formula showed no benefit and others actually showed an accelerated progression of the disease.

While AREDS can help about 35% of patients, almost 15% of patients being treated with AREDS supplements were made worse.

How do you know if you will benefit from AREDS vitamins or be harmed by taking the formula?

In 2018 a published paper revealed the link between patients individual genetics and how they respond to different supplement formulae after analyzing the AREDS study data futher.

Genetic testing can now be used to not only determine which vitamin formula is safe for you to take, but can also predict your indiviual risk of pregression to a more advance form of AMD.

This testing uses a sample obtained from a cheek swab and 3 weeks later the report is available.

Research, that started many years ago, has proven that by causing peripheral defocus of images on the retina, the progression of myopia can be slowed. This has been shown using special spectacle lenses as well as contact lenses.

There is now a commercially available, daily disposable contact lens available that is shown to slow the progression of myopia in children by 59%. This lens is called the MiSight 1 Day and is made by CooperVision.  

Using a proven material called omafilcon A, this comfortable 60% water lens breathes well with an oxygen transmissibilty value of 28.

It's special optical design causes periperal retinal defocus to correct refractive error while controlling axial elongation of the eye.

High degrees of myopia can lead to substantial vision loss. Myopia significantly increases the risk of retinal detachment and myopic maculopathy. Myopia is also associated with increased prevalence of glaucoma and cataracts.

By using MiSight contact lenses at least 10 hours per day, 6 days per week, myopia progression is reduced by 59%.

A 3 year study on a group of 8 to 12 year olds found 85% of children reported the MiSight  Day lenses were easy to insert and 90% said they preferred wearing the MiSight 1 Day to their glasses. 

Dr. Mungar has been certified by CooperVision to fit the MiSight 1 Day contact lens.

Hubble contact lenses are a daily disposable contact lens that has come onto the marketplace recently. These contacts are being advertised and promoted heavily on the internet and across social media. There is misleading information on the web and I will present some truths about this lens. 

Hubble contacts are produced in Taiwan and made from an old material called methafilcon A. This plastic came out decades ago and has been used to make a few different contact lens brands over the years. Methafilcon A has a very low oxygen transmissibilty value. This means that is does not breathe well. It is important for a soft contact lens to breath well so the eye receives enough oxygen to remain healthy. Methafilcon A breaths at a value of approximately 18. 

There are no other new contact lenses being made from Methafilcon A because it doesn't breathe well and other contact lens manufacturers have chosen to make all their new lenses from plastics that allow the eye to breathe better. Research has shown that the breathabilty value needs to be approximately 24 to maintian proper eye health. New materials tend to range from 40 to over 100. Remember Hubble's value is only 18! 

Hubble contact lenses are expensive! $40 per month plus $4 shipping. That's $528 per year! This is more expensive than many healthy, modern daily disposables.

So please don't be fooled by the extensive advertising. These are oldfashioned, outdated, potentially unhealthy yet expensive contact lenses.


Driving - many people love it, but for most of us it is a neccessity that provides us with a high degree of independence.

Studies have shown that many people feel insecure, tense, and stressed when driving - particularly when visibility is poor.

Rain, fog, mist, dusk and dawn - these are all conditions that reduce our visibility when driving. Good visibility is a must for safety and accident avoidance.

When visibility is poor we get tired and react more slowly.

There are now eyeglass lenses that help give drivers better vision.

Zeiss has examined driving vision in detail and designed lenses that provide improved vision by reducing glare, giving clearer vision of the instrument panel, and improving perceived visibilty in poor conditions.

The effect of blue light on our vision is a growing topic of discussion. We are exposed to light with blue components both indoors and outdoors. On the one hand, we need blue light for a healthy body and our general well-being. On the other hand, blue light can be dangerous, especially in strong sunshine. We protect ourselves with sunglasses when outdoors. There is an increase in the use of digital devices (which are back-lit by LEDs) and modern, energy efficient lighting (LED lights and compact fluorescent type bulbs), most of which emit a high level of blue light. LEDs contain about 35%  harmful blue light and compact fluorescents contain about 25% harmful blue light. By 2020, 90% of our light sources will be LED. Our exposure to blue light is everywhere and only increasing.

Do you work at a computer every day for long periods of time and in rooms with modern lighting systems? You may want to consider your next work glasses being coated to protect against the wavelengths of blue light.

Evening exposure to blue wavelengths of light can disrupt our natural sleep cycyles. For those of you who use digital screens in the evening hours before bed, you should be using blue protecting lenses.

Clear lenses with Zeiss DuraVision BlueProtect coating offer a durable, easy clean surface while protecting your eyes from blue light in the hazardous 390 to 440 nm wavelength range.

Dry eye affects at least 25 million Americans, and probably at least 3 million Canadians. Approximately 70% of people over 65 years old have dry eye symptoms.

With the increasing use of digital devices, and the decrease in blink rate when using digital devices, we are also now seeing much younger people with dry eye symptoms.

In our office we use the latest testing procedures to diagnose dry eye - from dry eye questionaires to assess severity of symptoms, to diagnostic testing to confirm the diagnosis.

Our office offers the latest in treatment options ranging from non-medical therapies to medical prescriptions. We offer at home treatment steps including hot compress masks such as the Bruder mask.

Various eyelid cleansing products are available, as are omega-3 supplements and preservative free eye drops. We also provide in-office eyelid micro-blepharoexfolliation using the Blephex tool.

Our medical treatment options range from prescription antibiotics (both drops and oral medications) to prescription anti-inflammatory drops to prescription immunomodulator drops like Restasis.

We are excited to offer BlephEx treatment to our patients in the battle against blepharitis and dry eye. Blepharitis and or dry eye affect upwards of half of the adult population. The BlephEx procedure removes the biofilm from the lid margins and lashes, decreasing the quantity of bacteria in these areas. The microexfoliation also exposes the tiny openings of the meibomian glands, allowing for better lipid release onto the tear layer.

We are very excited to announce a new monthly replacement contact lens now available in the Canadian market. Dr. Mungar has been chosen to be one of the first practices in Canada that will be fitting these new lenses, and in fact, the first location in Oakville to have these lenses available!

 This lens may be a more comfortable alternative for those patients currently wearing 2 week or monthly replacement lenses.

  • Outstanding breathability to maintain healthy eyes without the use of silicone
  • It matches the moisture level of the natural eye (has the highest water content of any daily disposable lens)
  • It mimics your own healthy tears resulting in less dehydration as the day goes on. 
  • It uses High Definition Optics - a proprietary technology which reduces halos and glare especially in low light
  • Lastly, it also provides UV protection
