With technology making life more and more convenient every day, there’s a growing trend toward online healthcare appointments. And eye care is no different. But what exactly can you get out of an online eye care appointment, and what should you still expect to visit your Thornhill eye doctor in person for? Let’s find out!
These appointments are ideal for people on the go who are not suffering from any particular vision issues or symptoms. They are meant as a convenient way to update stable prescriptions for young adults between the ages of 18 and 40 who have no eye health issues and are experiencing no change in their vision. No eye doctor is present for these kinds of appointments.
Telehealth Visits
These appointments offer a face-to-face meeting with your eye doctor online, usually through a specialized telehealth service optimized for your privacy. They are for patients who may already be established with the practice or have complaints related to the outside of the eye or the eyelids, such as a black eye or stye. Nonetheless, even a telehealth appointment with the highest-quality webcam can’t give your eye doctor nearly as much information as they can get from high-resolution imaging equipment in-office.
In-Person Comprehensive Eye Exams
This is the most thorough type of eye exam. It allows your eye doctor to utilize the latest eye care technology to measure your level of refractive error, test your inner eye pressure to check for signs of glaucoma, take images and scans of your retina to guard against retinal detachment and macular degeneration, and more.
Many potentially sight-threatening conditions show no signs or symptoms until significant damage to the eye has already been done. These conditions can only be detected with a thorough in-person eye exam.
Are you suffering from red, irritated and scratchy eyes? Do you feel like you have something stuck in your eyes? These are hallmark symptoms of dry eye syndrome, a condition that occurs when your eyes are not properly lubricated due to insufficient tear production, blocked glands, or unbalanced tear composition.
The symptoms can be so unpleasant that many rush to the nearest pharmacy to find the perfect eye drops that will offer them the relief they need so that they can get back to focusing on other things.
However, seeking the ideal artificial tears to relieve dry eyes can be a daunting process. The eye drops shelf at the drug store offers so many options that it's hard to know which ones are right for you. What's more, some can actually make your symptoms worse.
Not all eye drops are created equal—currently, there are 6 main categories of artificial tears available over the counter. Choosing the artificial tears based on your specific needs can help narrow your options.
The 6 Types of Eye Drops / Artificial Tears
Preserved Artificial Tears
Preserved artificial tears contain added preservatives to maintain a very long shelf and keep bacteria at bay once the bottle is opened. Unfortunately, it also causes inflammatory dry eye disease, meibomian gland dysfunction and an allergic reaction in those who are sensitive, leading to redness, irritation and inflammation. While these drops may offer temporary relief, long term they can do more harm than good. Moreover, the preservatives may leave residue on contact lenses.
Preservative-Free Artificial Tears
Preservative-free artificial tears are great for contact lens wearers as they don't cause any preservative build-up on the lenses. They are also suitable for those with sensitive eyes since they contain fewer ingredients that can cause irritation.
Preservative-free eye drops typically come in a box of 28 to 30 small vials that fit in a pocket or purse.
To use these drops, just pop the top off and insert the drops into your eyes. Some of these vials can be re-capped to allow you to continue to use the vial for up to 24 hours, but not longer. Refrigerate opened vials between uses to prevent any bacterial growth.
Oil-Based Artificial Tears
Oil-based tears come in preserved and preservative-free versions. These are thicker than traditional eye drops, as they contain an oil-based formulation. The oil helps prevent the watery portion of the tears from evaporating too quickly.
If you suffer from moderate or severe dry eye, oil-based artificial tears may be a great option. However, they’re not recommended for contact lens wearers, as the oils may stick to the surface of the lenses, making it difficult to keep them clean.
Eye Drop Spray or Mist
These sprays are preservative-free and are used to relieve dryness and irritation in both the eyes and eyelids. They’re easy to use, especially for those who struggle to insert drops into their eyes.
To use the spray, just close your eyes and spray onto your closed eyelids. Once you blink, the tears will slide into your eyes.
Don't use the spray if you're wearing makeup, lotions, or creams on your eyelids, as it can cause the makeup or lotion to enter your eye.
Artificial Tear Gel
Artificial tear gel adds a thick coating of tears and can be used at any time of the day or night. However, the thicker consistency of the gel drop may blur your vision for several minutes.
The gel is applied in the same way as eye drops. It effectively soothes the eyes and provides extended relief for both moderate to severe dry eye.
Most artificial tear gels contain preservatives, so they can only be used up to 4 times a day, and usually they are not safe for contact lens wearers.
Artificial Tear Ointment
Dry eye ointments are thick and coat the front of your eye. They're usually used 1 to 2 times daily as needed. It may be best to use them at bedtime, as it will blur your vision.
Get Dry Eye Relief Today!
Artificial tears may be a good way to temporarily relieve eye dryness. However, using the wrong type of eye drops can be worse than not using any drops at all. So be sure to consult your eye doctor before you get eye drops.
Keep in mind that eye drops don’t address the root cause of dry eyes; they just provide temporary respite from the uncomfortable dry eye symptoms. Only an eye doctor can examine your eyes to determine the underlying cause of your symptoms and recommend the best treatment for your unique case of dry eye.

Q&A
What is dry eye syndrome?
Dry eye syndrome is a condition where your eyes either produce low-quality tears or don’t produce enough tears to keep your eyes hydrated. This may be due to certain diseases (like diabetes or other autoimmune diseases), aging, allergies, hormonal changes, smoking, poor air quality, medications and the environment.
What are the symptoms of dry eye syndrome?
Dry eye syndrome can cause a wide range of symptoms including:
Myopia, or nearsightedness, is one of the most common eye conditions affecting millions of people around the world.
Myopia is a refractive error in which the eyes are unable to focus clearly on images or objects. This results in blurry vision when looking at something at a distance, such as people walking down a street, a school board, or even the TV. However, images that are closer can be seen more clearly. Children with uncorrected myopia tend to experience eye strain, eye fatigue, or headaches in an effort to see images in the distance clearly.
Fortunately, eyeglasses or contact lenses work wonders to correct vision. In this text, we’ll discuss both glasses and contacts as options for myopia correction.
Methods of Myopia Correction
Contact Lenses
Contacts can be a great choice, especially for physically active children or teens who don’t want to worry about breaking or misplacing their eyeglasses.
Corrective contact lenses are usually placed in the eyes upon waking and removed at night before bedtime. We offer a range of brands of soft contact lenses, such as daily disposables and extended-wear disposables. Speak with Dr. Murtaza Jafferji to determine whether your child is ready for contact lenses.
Prescription Glasses
Glasses are a popular choice among our younger patients. Choosing from an array of styles makes the process not just fun and exciting, but allows the child to be an active participant in selecting eyewear, which, in turn, increases the likelihood that they’ll actually wear them. We offer strong, flexible and resilient frames which both look great and are feel comfortable.
The optician can customize the lenses with additions, like impact-resistant or shatter-proof materials, scratch-resistant and anti-reflective coatings, UV filters, and transition lenses that darken in the sun.
We Can Help Correct Your Child’s Myopia
If you’re located near Thornhill, Ontario, visit us for an eye exam to determine your child’s exact prescription and ask us any questions you may have about your child’s eye health and vision.
At Urban Opticians, our friendly and knowledgeable staff will be happy to recommend the most suitable method of correcting your child’s myopia to meet his or her individual needs. Thanks to the wide range options available, your child will walk away with eyewear that will both look and feel great.
Let us help your child see the world in a whole new light. To schedule your child’s annual eye exam or to learn more, contact Urban Opticians at 905-731-0341 today.
Whether you live in a climate with cold winter weather or you are planning a ski trip up north, winter can be a challenge if you suffer from dry eyes. Dry, cool air, cold winds and even drier indoor heating can cause eye irritation, burning, itchiness and redness, and sometimes even excessively watery eyes as more tears are produced to compensate for the dryness. Many people have a chronic feeling that they have something in their eye and some even experience blurred vision. These symptoms can be debilitating!
Dry eyes is one of the most common complaints eye doctors get from patients during the winter season, especially in the cooler climates. That’s why we’d like to share some tips on how to relieve dry eye discomfort, and how to know when your condition is serious enough to come in for an evaluation.
Tips to Relieve Winter Dry Eyes:
Keep eyes moist using artificial tears or eye drops. You can apply these a few times each day when the eyes are feeling dry or irritated. If over-the-counter drops don’t help or if you have chronic dry eyes, speak to your eye doctor about finding the best drops for you. Since not all artificial tears are the same, knowing the cause of your dry eye will help your eye doctor determine which brand is best suited for your eyes.
Use a humidifier to counteract the drying effects of indoor heaters or generally dry air.
Point car vents or indoor heaters away from your face when the heat is on. Try to keep your distance from direct sources of heating, especially if they blow out the heat.
Drink a lot! Hydrating your body will also hydrate your eyes.
Protect your eyes outdoors with sunglasses or goggles – the bigger the better! Larger, even wrap-around glasses as well as a hat with a wide brim will keep the wind and other elements out of your eyes. If you wear goggles for winter sports, make sure they fit well and cover a large surface area.
Soothe dry eyes using a warm compress and never rub them! Rubbing your eyes will increase irritation and may lead to infection if the hands are not clean.
Give your eyes a digital break. People blink less during screen time which is why extensive computer use can lead to dry eyes. Follow the 20/20/20 rule by taking a break every 20 minutes to look 20 feet away for 20 seconds and make sure you blink!
For contact lens wearers: If you wear contact lenses, dry eyes can be particularly debilitating as the contact lenses can cause even further dryness and irritation. Contact lens rewetting drops can help your eyes feel better and may also allow you to see more clearly. Not all eyedrops are appropriate for use with contact lenses, so ask your optometrist which eyedrop is compatible with your contacts and cleaning solution. If rewetting drops don’t help, consider opting for glasses when your dry eyes are bad, and speak to your optometrist about which brands of contact lenses are better for dry eyes. Many people find dry eye improvement when they switch to daily single use contact lenses.
Chronic Dry Eyes or Dry Eye Syndrome
Dry eye syndrome is a chronic condition in which the eyes do not produce enough tear film, or do not produce the quality of tear film needed to properly keep the eyes moist. While winter weather can make this condition worse, it is often present all year round. If you find that the tips above do not alleviate your discomfort or symptoms, it may be time to see a optometrist to see if your condition requires more effective medical treatment.
Diabetes is becoming much more prevalent around the globe. According to the International Diabetes Federation, approximately 425 million adults were living with diabetes in the year 2017 and 352 million more people were at risk of developing type 2 diabetes. By 2045 the number of people diagnosed is expected to rise to 629 million.
Diabetes is a leading cause of blindness as well as heart attacks, stroke, kidney failure, neuropathy (nerve damage) and lower limb amputation. In fact, in 2017, diabetes was implicated in 4 million deaths worldwide. Nevertheless preventing these complications from diabetes is possible with proper treatment, medication and regular medical screenings as well as improving your diet, physical activity and adopting a healthy lifestyle.
What is Diabetes?
Diabetes is a chronic disease in which the hormone insulin is either underproduced or ineffective in its ability to regulate blood sugar. Uncontrolled diabetes leads to hyperglycemia, or high blood sugar, which damages many systems in the body such as the blood vessels and the nervous system.
How Does Diabetes Affect The Eyes?
Diabetic eye disease is a group of conditions which are caused, or worsened, by diabetes; including: diabetic retinopathy, diabetic macular edema, glaucoma and cataracts. Diabetes increases the risk of cataracts by four times, and can increase dryness and reduce cornea sensation.
In diabetic retinopathy, over time, the tiny blood vessels within the eyes become damaged, causing leakage, poor oxygen circulation, then scarring of the sensitive tissue within the retina, which can result in further cell damage and scarring.
The longer you have diabetes, and the longer your blood sugar levels remain uncontrolled, the higher the chances of developing diabetic eye disease. Unlike many other vision-threatening conditions which are more prevalent in older individuals, diabetic eye disease is one of the main causes of vision loss in the younger, working-age population. Unfortunately, these eye conditions can lead to blindness if not caught early and treated. In fact, 2.6% of blindness worldwide is due to diabetes.
Diabetic Retinopathy
As mentioned above, diabetes can result in cumulative damage to the blood vessels in the retina, the light-sensitive tissue located at the back of the eye. This is called diabetic retinopathy.
The retina is responsible for converting the light it receives into visual signals to the optic nerve in the brain. High blood sugar levels can cause the blood vessels in the retina to leak or hemorrhage, causing bleeding and distorting vision. In advanced stages, new blood vessels may begin to grow on the retinal surface causing scarring and further damaging cells in the retina. Diabetic retinopathy can eventually lead to blindness.
Signs and Symptoms of Diabetic Retinopathy
The early stages of diabetic retinopathy often have no symptoms, which is why it’s vitally important to have frequent diabetic eye exams. As it progresses you may start to notice the following symptoms:
Blurred or fluctuating vision or vision loss
Floaters (dark spots or strings that appear to float in your visual field)
Blind spots
Color vision loss
There is no pain associated with diabetic retinopathy to signal any issues. If not controlled, as retinopathy continues it can cause retinal detachment and macular edema, two other serious conditions that threaten vision. Again, there are often NO signs or symptoms until more advanced stages.
A person with diabetes can do their part to control their blood sugar level. Following the physician’s medication plan, as well as diet and exercise recommendations can help slow the progression of diabetic retinopathy.
Retinal Detachment
Scar tissues caused by the breaking and forming of blood vessels in advanced retinopathy can lead to a retinal detachment in which the retina pulls away from the underlying tissue. This condition is a medical emergency and must be treated immediately as it can lead to permanent vision loss. Signs of a retinal detachment include a sudden onset of floaters or flashes in the vision.
Diabetic Macular Edema (DME)
Diabetic macular edema occurs when the macula, a part of the retina responsible for clear central vision, becomes full of fluid (edema). It is a complication of diabetic retinopathy that occurs in about half of patients, and causes vision loss.
Treatment for Diabetic Retinopathy and Diabetic Macular Edema
While vision loss from diabetic retinopathy and DME often can’t be restored, with early detection there are some preventative treatments available. Proliferative diabetic retinopathy (when the blood vessels begin to grow abnormally) can be treated by laser surgery, injections or a procedure called vitrectomy in which the vitreous gel in the center of the eye is removed and replaced. This will treat bleeding caused by ruptured blood vessels. DME can be treated with injection therapy, laser surgery or corticosteroids.
Prevent Vision Loss from Diabetes
The best way to prevent vision loss from diabetic eye disease is early detection and treatment. Since there may be no symptoms in the early stages, regular diabetic eye exams are critical for early diagnosis. In fact diabetics are now sometimes monitored by their health insurance to see if they are getting regular eye exams and premium rates can be affected by how regularly the patients get their eyes checked. Keeping diabetes under control through exercise, diet, medication and regular screenings will help to reduce the chances of vision loss and blindness from diabetes.
Whether it is homework, email, gaming, chatting with friends, searching the web or watching Youtube, kids these days seem to have an endless number of reasons to be glued to a screen. Many parents out there are wondering how bad this can be for their kids and whether they should be limiting screen time.
There are certainly benefits to allowing your kids to use digital devices, whether it is educational, social or providing a needed break. However, studies show that excessive screen time can have behavioral consequences such as irritability, moodiness, inability to concentrate, poor behavior, and other issues as well. Too much screen time is also linked to dry eyes and meibomian gland disorders (likely due to a decreased blink rate when using devices), as well as eye strain and irritation, headaches, back or neck and shoulder pain, and sleep disturbances. Some of these computer vision syndrome symptoms are attributed to blue light that is emitted from the screens of digital devices.
Blue light is a short wavelength, high-energy visible light that is emitted by digital screens, LED lights and the sun. Studies suggest that exposure to some waves of blue light over extended periods of time may be harmful to the light-sensitive cells of the retina at the back of the eye. When these cells are damaged, vision loss can occur. Research indicates that extreme blue light exposure could lead to macular degeneration or other serious eye diseases that can cause vision loss and blindness. Studies show that blue light also interferes with the regulation of the the body’s circadian rhythm which can have a disruptive impact on the body’s sleep cycle. Lack of quality sleep can lead to serious health consequences as well.
Beyond these studies, the long term effects of blue light exposure from digital devices are not yet known since this is really the first generation in which people are using digital devices to such an extent. While it may take years to fully understand the impact of excessive screen time on our eyes and overall health, it is probably worth limiting it due to these preliminary findings and the risks it may pose. This is especially true for young children and the elderly, who are particularly susceptible to blue light exposure.
How to Protect the Eyes From Blue Light
The first step in proper eye protection is abstaining from excessive exposure by limiting the amount of time spent using a computer, smart phone or tablet - especially at night, to avoid interfering with sleep. Many pediatricians even recommend zero screen time for children under two.
The next step would be to reduce the amount of blue light entering the eyes by using blue light blocking glasses or coatings that deflect the light away from the eyes. There are also apps and screen filters that you can add to your devices to reduce the amount of blue light being projected from the screen. Speak to your eye doctor about steps you can take to reduce blue light exposure from digital devices.
As a side note, the sun is an even greater source of blue light so it is essential to protect your child’s eyes with UV and blue light blocking sunglasses any time your child goes outside - even on overcast days.
The eyes of children under 18 are particularly susceptible to damage from environmental exposure as they have transparent crystalline lenses that are more susceptible to both UV and blue light rays. While the effects (such as increased risk of age-related macular degeneration) may not be seen for decades later, it’s worth it to do what you can now to prevent future damage and risk for vision loss.
Hey women! Did you know that women are more likely to suffer from vision problems and are at higher risk of permanent vision loss than men? Well 91% of the women surveyed recently didn’t know that, which means that many of them aren’t taking the necessary precautions to prevent eye damage and vision loss.
According to a recent study, the statistics for many of the major vision problems show that women have a higher percentage of incidence than men. These include:
Age-related Macular Degeneration 65%
Cataracts 61%
Glaucoma 61%
Refractive Error 56%
Vision Impairment 63%
Women are also more susceptible to develop chronic dry eye, partially because it is often associated with other health issues that are more common in women such as ocular rosacea which is three times more prevalent in women. Hormonal changes during pregnancy and menopause can also contribute to dry eye.
It’s important for women to know the risks for eye-related diseases and vision impairment and the steps they can take to prevent eventual vision loss. Here are some ways that you can help to protect your eyes and save your eyesight:
Find out about family history of eye diseases and conditions.
Protect your eyes from the sun by wearing 100% UV blocking sunglasses when outdoors.
Don’t smoke.
Consume a healthy diet with proper nutrition and special eye health supplements as prescribed by an eye doctor.
Adhere to contact lens hygiene and safety.
Adhere to cosmetic hygiene and safety precautions.
Protect your eyes against extended exposure to blue light from computers, smartphones and LED lamps.
If you are pregnant or planning to become pregnant and have diabetes, see an eye doctor for a comprehensive eye exam. In women who have diabetes, diabetic retinopathy can accelerate quickly during pregnancy and can present a risk for the baby as well.
Mothers are often charged with caring for the eye health of the entire family, but too often their own eye health needs fall to the wayside. It is critical that mothers take care of their eyes and overall health so that they can be in the best condition to care for their families.
Speak to your eye care professional about your personal eye health and vision risks and the precautions and measures you should take to protect your eyes. Encourage the other women in your life to do so as well. Once vision is lost, it often can’t be regained and there are many steps you can take to prevent it with proper knowledge and awareness.
The most important way to prevent vision loss is to ensure you schedule regular eye exams. Don’t wait for symptoms to appear as many eye issues are painless and symptomless, and sometimes by the time you notice symptoms, vision loss is untreatable.
Eye color is a hereditary trait that depends on the genes of both parents, as well as a little bit of mystery. The color of the eye is based on the pigments in the iris, which is a colored ring of muscle located at the center of the eye (around the pupil) that helps to control the amount of light that comes into your eye. Eye color falls on a spectrum of color that can range from dark brown, to gray, to green, to blue, with a whole lot of variation in between.
Genetics
The genetics of eye color are anything but straightforward. In fact children are often born with a different eye color than either of their parents. For some time the belief was that two blue-eyed parents could not have a brown-eyed child, however, while it’s not common, this combination can and does occur. Genetic research in regards to eye color is an ongoing pursuit and while they have identified certain genes that play a role, researchers still do not know exactly how many genes are involved and to what extent each gene affects the final eye color.
The Iris
Looking at it simply, the color of the eye is based on the amount of the pigment melanin located in the iris. Large amounts of melanin result in brown eyes, while blue eyes result from smaller amounts of the pigment. This is why babies that are born with blue eyes (who often have smaller amounts of melanin until they are about a year old) often experience a darkening of their eye color as they grow and develop more melanin in the iris. In adults across the globe, the most common eye color worldwide is brown, while lighter colors such as blue, green and hazel are found predominantly in the Caucasian population.
Abnormal Eye Color
Sometimes the color of a person’s eyes are not normal. Here are some interesting causes of this phenomenon.
Heterochromia, for example, is a condition in which the two eyes are different colors, or part of one eye is a different color. This can be caused by genetic inconsistencies, issues that occur during the development of the eye, or acquired later in life due to an injury or disease.
Ocular albinism is a condition in which the eye is a very light color due to low levels of pigmentation in the iris, which is the result of a genetic mutation. It is usually accompanied by serious vision problems. Oculocutaneous albinism is a similar mutation in the body’s ability to produce and store melanin that affects skin and hair color in addition to the eyes.
Eye color can also be affected by certain medications. For example, a certain glaucoma eye drop is known to darken light irises to brown, as well as lengthen and darken eyelashes.
Eye Color – It’s More Than Meets the Eye
It is known that light eyes are more sensitive to light, which is why it might be hard for someone with blue or green eyes to go out into the sun without sunglasses. Light eyes have also shown to be a risk factor for certain conditions including age-related macular degeneration (AMD).
Color Contact Lenses
While we can’t pick our eye color, we can always play around with different looks using colored contact lenses. Just be sure that you get a proper prescription for any contact lenses, including cosmetic colored lenses, from an eye doctor! Wearing contact lenses that were obtained without a prescription could be dangerous to your eyes and your vision.
