LipiFlow is an FDA approved medical device for treating meibomian gland disease.

Meibomian gland disease or dysfunction (MGD) refers to the condition where the meibomian glands are not secreting enough oil or when the oil they secrete is of poor quality. Often, the oil gland openings get blocked so that less oil comes out of the gland. The oil that does make it out of the glands can be thickened and unhealthy and can cause irritation. It is believed that 86% of dry eye cases are due to MGD.

The LipiFlow System represents more than 10 years of dedicated research and is protected by more than 30 patents. It uses precisely controlled therapeutic heat and massage to relieve gland blockages. LipiFlow is safe and pain-free.

Patented components called Activators deliver treatments directly to the inner and outer eyelids while protecting delicate eye tissue. Sterile and single-use, the Activators are designed for safety and comfort.

Each treatment takes about 12 minutes. Most patients find improvement of their symptoms in as little as two weeks, with the results lasting 12 months or more. Dr. Mungar and his staff can guide you on what to expect.

The iWellness scan is a quick, non-invasive scan that allows the doctor to see beneath the surface of your retina and view each of the individual 10 cell layers to evaluate your retina in greater detail than ever before. This unique technology can help Dr. Mungar detect vision-threatening diseases in their earliest stages, when they are most treatable. This scan also serves as a baseline to compare future scans to, allowing us to monitor for change over time.

The iWellness scan incorporates cell analysis and imaging, using spectral domain optical coherence tomography, allowing the doctor to look for early signs of diseases such as glaucoma, macular degeneration, diabetic retinopathy, high blood pressure and many more.

Your eyesight is priceless, and we are here to protect it! Vision-threatening diseases often have no outward signs or symptoms in the early stages, so our practice has begun using this state-of-the-art technology to better assess the health of your eyes.

We are excited to be the only office in the area to offer patients the iWellness Scan.

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.

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.

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. There is between 30 and 50 times more blue light in sunlight than from any digital device. We need blue light during the daytime for a healthy body and our general well-being. We need a decrease in blue light in the evening to regulate our sleep cycles.

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 blue light. LEDs contain about 35%  blue light and compact fluorescents contain about 25% blue light. By 2020, 90% of our light sources will be LED. Our exposure to blue light is everywhere and only increasing.

There is no evidence currently to show that we need to protect ourselves from blue light. There is also no evidence to show that blue protecting lenses make computer use more comfortable. 

We do, however, know that evening exposure to blue wavelengths of light can disrupt our natural sleep cycles. For those of you who use digital screens in the evening hours before bed, you should consider using blue protecting lenses.
