The Dangers of Blue Light and What You Can Do
We are privileged to live in an advanced age at the turn of the 21st century. Electronic devices are everywhere in our world today and make our everyday interactions with the world around us ever easier, safer and more convenient. Although many positive effects have resulted from these devices in our everyday lives, a darker, more dangerous side exists to all of this progress and convenience.
Blue light, also known as high energy visible light, is emitted by many of these electronics, and is a serious threat to eye health which was previously unknown and irrelevant in generations past.
Living in such an advanced age, each of us, on average, spends roughly 25 hours every week staring at the screen of one of our electronic devices. To put this in perspective, that means that each of us spend more than one entire day, without sleeping, in front of devices that emit blue light that is proven to do serious damage to our visual system. Eyestrain, headaches and fatigue are common side effects. Even more alarming, recent studies indicate that blue light exposure has the potential to increase risk of macular degeneration significantly over time. Those with a history of macular degeneration are at special risk, as well as children, due to large pupils and shorter arms, which cause them to hold electronic devices closer to their faces, both of which allow more blue light to penetrate the eye.
Fortunately, cutting edge technological solutions to this growing epidemic exist. BluTech Lenses are special lenses specifically designed to selectively filter out blue light, enhancing visual comfort and minimizing eyestrain. These lenses boast a special state-of-the-art filtering agent within the lens material itself that duplicates elements in the eye, called ocular lens pigment and melanin, which the body naturally produces on its own, and which help filter out just the right amount of blue light entering the eye to protect against unfettered blue light penetration, while allowing proper visual contrast.
Recharge is another cutting edge option to help cut down on the harmful effects of blue light. HOYA is the advanced eye care company that produces these lenses, which reflect up to 30% of harmful blue light away from the eye.
Between the filtering effect of BluTech and the reflective properties of the Recharge coating, a large percentage of otherwise very harmful blue light never reaches the eye. This is an extremely important element in the long term health of your eyes.
Patients who spend hours on electronic devices are at increased risk of eyestrain and glare, macular degeneration or problems falling asleep at night. For more information about blue light and recharge lenses, speak to the optometrists and our team today at Dr Pink Sidhu and Associates.
Myopia (nearsightedness) is occurring in children more frequently, at a younger age and to a greater degree than ever before. Unfortunately, childhood myopia leads to a high prescription come adulthood, resulting in thick glasses or a dependence on contact lenses.
How Does Myopia Control Work?
Myopia may increase as a result of an elongated eye, where the focal point falls in front of the retina. This is often genetic. Another cause of myopia progression is visual fatigue and stress on the eye from too much near activity and not enough time outdoors. This is the likely cause of the increase in incidence of childhood myopia abundantly seen today. Myopia control treatments exercise the eye muscles, allowing for small changes to the eye’s overall structure or focusing process to reduce eye strain. Myopia control is a type of physical therapy for your child’s eyes and is designed to slow down the progression of myopia. Early intervention is crucial to keeping the prescription from climbing, preserving your child’s uncorrected distance vision.Dr Pink sidhu and Associates offers a variety of myopia control treatments for your family. For more information about myopia control request an appointment for your child today.
We Use 3 Methods
Distance glasses are the most common treatment for childhood myopia. Although they will improve your child’s distance vision and allow them to see the blackboard in school or the television, they can actually make it harder for your child’s eyes to focus on things close up, causing strain. Multifocal glasses and contact lenses, have different corrective powers throughout the lens, allowing your child to see clearly at distance with a lesser power at near to alleviate eye strain or visual fatigue. This in turn prevents their prescription from increasing too quickly. lenses
Myopia Control Specialty lenses
Hoya Mysmart Dimms Technology
Low-dose atropine eye drops are another form of myopia control for children, recommended by Dr. Pink Sidhu and Associates. These drops are administered to your child on a daily basis to reduce eye strain and slow the progression of myopia. The drops temporarily reduce the eye’s ability to focus at near, relaxing the eyes and controlling myopia. Side effects include slightly dilated pupils.

It’s almost back to school time for college students and whether this is your first time away from home or you are already a pro, you want to be prepared with as much knowledge as possible to live safely on your own. This knowledge includes eye and vision safety, as failing to take care of your eyes today could cause damage to your eyes and vision now and in the future.
So put down your textbooks for a second and learn these four simple lessons about protecting your precious eyes.
Blue Light Protection
College students spend a lot of time in front of screens. From each class, homework assignment, and research project, to texting, dating apps and watching Netflix and gaming – life is largely digital.
This comes with a slew of potential side effects known as computer vision syndrome, including sore and tired eyes, headaches, neck, shoulder and back pain, dry eyes and blurred vision, largely due to the effect of the blue light emitted from the screens. The additional computer usage also increases dry eye symptoms. Studies show that blue light can also impact your sleep quality and may possibly be connected to the development of retinal damage and macular degeneration later in life.
You must always protect your eyes and vision from blue light and computer vision syndrome, and here’s how you do it:
- Use computer glasses or blue-light blocking coated lenses or contact lenses when working on a screen for long periods of time. These lenses are made to allow optimal visual comfort for the distance and unique pixelation of working on a computer or mobile screen, by reducing glare and eye strain. They also block potentially harmful blue-light radiation from entering your eyes.
- Prescription glasses may be considered as well. Many students who never needed glasses previously experience eyestrain with extensive hours studying in university. A minor prescription can make a big difference in reducing eye fatigue and helping to improve concentration. See our clinic Pink Sidhu and Associates for your eyecare needs.
- Although there is no clinical support for the 20-20-20 rule, Implementing the 20-20-20 rule by taking a break every 20 minutes to look at something 20 feet away for 20 seconds allows your eyes to have a healthy medium between work and rest for your eyes from the intensity of the computer screen.
- Depending on your environment, eye drops, and other dry eye services and products can be prescribed from the eye doctor to assist with dry eye syndrome that often accompanies increased screen time. Did you know that your blink rate often goes down substantially when you are concentrating on reading or computer work, thus exasperating dry eye symptoms? Have you tried eyedrops that just never seem to work? Come see Dr. Pink Sidhu and associates to discuss a personalized dry eye treatment plan for you. Did you know that 80% of dry eye sufferers have some form or meibomian gland dysfunction?
Our clinic offers treatment and management to tackle your dry eye symptoms stemming from this dysfunction. This may include meibomian gland expression. You may read more about our dry eye services in our dry eye clinic tab.
We have discussed vision correction, computer strain, dry eye, and blue block lenses. Let’s now talk about proper contact lens use.
Many college students opt for contact lenses as they are convenient and great for cosmesis and another means of vision correction, but they come along with responsibility.
The busy days and late nights can sometimes make contact lens care difficult. You must follow your eye doctor’s instructions for proper care.
Speak to Dr. Pink and Associates about your contact lens interest today. Always follow the wearing schedule and never sleep in lenses that are not designed for extended wear.
Clean and disinfect as needed, and don’t rinse them with anything other than contact lens solution. No, saliva is not safe for your contact lens, yet many students will admit they do it.
Failing to follow the proper use and hygiene for contact lenses can result in irritation, infections and even corneal scarring which can result in vision reduction and/ or vision loss.
One-day disposable lenses can be a great option especially for college students as they offer ultimate convenience (no cleaning and storing) and optimal eye health.
Further, if you enjoy wearing contact lenses, then remember to get a proper fit from your eye doctor. Many “exclusive” contact lenses available online may actually be poorly fit and made from inferior materials. Contrary to popular belief, one size does not fit all.
Lastly, let’s talk about sun protection and UV Protection.
Ultraviolet rays from the sun are known to cause long term eye damage and lead to vision-threatening eye conditions such as macular degeneration and cataracts. Additionally, in extreme cases of unprotected UV exposure, you can get sunburned eyes, known as photokeratitis, which can cause a gritty, dry feeling, burning, swelling, light sensitivity, vision changes, and sometimes serious pain. These symptoms typically go away within a day or two.
Wearing 100% UV reflective sunglasses whenever you are outside – rain or shine – is the first step to eye protection. A large brimmed hat to protect the eyes from exposure from the top and sides is also a recommended addition for sunny days. It’s especially important for the light colored eyes.
Get a regular eye exam
To start off college with the right foot forward, it’s recommended to get a comprehensive eye exam prior to the start of the school year, especially if you haven’t had one recently. This way you can ensure that your eyes and vision are in top shape and, if you wear glasses, that your prescription is still accurate.
The last thing you want to worry about when getting adjusted to college is problems with your eyes and vision. It’s also recommended for students that are going away to another city to get a recommendation for a local eye doctor in case of an emergency. Most eye doctors know of colleagues located in other cities who they could recommend.
Just remember to think about your eyes because the better you take care of them now, the healthier eyes and vision you will have down the road. It’s one pair of eyes that will last you a lifetime.
Most college students have vision insurance. Most of our patients are Humber college students because of how close your campus is to the office. Check with your insurance or have our office at Dr. Pink Sidhu and associates check it out for you. We have student specials to make for an affordable and educational visit.
This summer, whether you’re headed across state lines on a family road trip, flying off to Europe, grabbing a quick weekend getaway, or taking a vacation in your own backyard, don’t forget to protect your eyes!
Summer Eye Care Near You
Check out our top 4 tips for ensuring healthy eyes this summer, and remember, your eye doctor is here to help make the most out of your vision. Dr. Pink Sidhu sees patients from all over the York, Toronto area. Let us give you the top-quality eye care you and your family deserve, not only during the summer, but all year long.
Don’t Leave Home Without It
If you have a chronic illness and need to head out of town for a few days, you would never leave home without your medications, right? That’s because you know that if something happens and your meds aren’t with you, you could suffer discomfort or complications to your health.
The same is true for your vision. If you suffer from dry eyes, make sure to take artificial tears or medicated eye drops with you when you travel. Preservative-free eye drops are a traveler’s friend. They’re also available as individual strips, which are recommended since there’s less risk of contamination.
Running low on disposable contact lenses? Include an extra pair in your carry-on suitcase and stock up on new lenses ahead of time. If you wear eyeglasses, bring a spare set and a copy of your prescription along with you, just in case they get lost or broken.
We recommend speaking to Dr. Pink Sidhu before you leave for vacation to make sure your vision needs are all set.
It’s Getting Hot Outside
Usually, most people think of protecting their skin from sunburns when they’re at the beach, by the pool, or just spending time outdoors.
Did you know that your eyes can get sunburned, too?
This happens when the cornea is exposed to excessive UV rays. When the sclera (the white part of your eye) looks red, that’s a sign that you’ve got sunburned eyes. You might also notice symptoms like a sudden sensitivity to light, or your eyes may feel like something is stuck in them, or they could feel sore.
The best way to prevent sunburned eyes? Always wear sunglasses with 100% of UVA and UVB light blocking protection.
Watch Out for the Pool
Swimming is one of summer’s greatest pastimes. There’s nothing quite like a dip in a pool or ocean to cool off from the sweltering summer heat. While you’re slicing through the water, remember to protect your eyes.
Remove contacts before going swimming, wear goggles while underwater, and rinse your eyes with cold water when you get out of the pool (it helps get the chlorine or salt out). If your eyes feel dry or scratchy after a swim, use some moisturizing eye drops to lubricate your eyes.
Back to School is Sooner Than You Think
Your kids will be back in school before you know it. Help them prepare for the upcoming school year by scheduling an eye exam now. If they need new glasses because their prescription has changed or your teen simply wants a new look for the new school year, come in to Pink Sidhu and Associates for a consultation and take a look at the newest selection of frames and contact lenses.
Have you had a sudden eye injury or emergency while on vacation? Don’t wait until you’re back home to handle it — seek immediate care today. Certain eye injuries can damage your vision or lead to ulcers, so if you notice symptoms like redness, eye pain, changes to your vision, or flashing light, contact your eye doctor right away.
At Pink Sidhu and Associates, we put your family’s needs first. Talk to us about how we can help you maintain healthy vision this summer and throughout the year.
The Eye See Eye Learn program is an organization providing comprehensive eye exams and glasses to Junior Kindergarten children in certain school regions for free, courtesy of the participating sponsors (Nikon Lenswear and OGI). The eye exams are covered by OHIP, as are eye exams for any child 19 years or younger with a valid Ontario health card.
Eye See Eye Learn is a relatively new program in Ontario. The program provides comprehensive eye examinations to Junior Kindergarten children in certain school regions (including the Thames Valley District School Board). The eye exams are covered by OHIP, as are eye exams for any child 19 years or younger with a valid Ontario health card.
The exciting part of the Eye See Eye Learn program is that if the child in Junior Kindergarten needs glasses, they will receive them for free courtesy of the participating sponsors (Nikon Lenswear and OGI).
This program was developed to raise awareness among parents of the importance of having their children’s’ eyes examined upon starting school. Children who can’t see the board or focus on a picture or follow words in a book may struggle to achieve their full learning potential. Vision problems can also impact their social development and hand-eye coordination for physical activities. 80% of learning comes directly through vision.
Children who are born with blurry vision, due to high prescription or eye health abnormality, don’t know what “clear” vision is and wouldn’t know to complain of vision problems. Catching these problems early is key. The Eye See Eye Learn program aims to give Junior Kindergarten students the best start to learning.

Vision is more than 20/20.
- Did your child’s school teacher tell you that your child needs to see an optometrist?
- Did your child pass or fail a school screening?
- Is your child rubbing the eyes?
- Are their any headaches that you feel are related to the eyes?
- Is your child recently diagnosed with a “ learning disability?”
- Or told that he/ she is disruptive in the classroom?
These are just a few of the symptoms your child might be experiencing or scenarios that you, as parents, might be experiencing as a family. Studies support that 70% of kids with behavioral “problems”, may just have an underlying vision problem. Unlike the screenings at your school, or in a Pediatrician’s or family doctor’s office, your eye exam with Dr. Pink and associates is more than just a 20/20 sight test.
We test for your child’s ability to see the chart at distance and near. Our York optometrists recognize that children can be nervous or shy and/ or just simply not interested. And that’s okay, we may bring them back for multiple visits throughout the year because every visit will give us a little more information each time. We track their ability to follow a moving target, and to zoom in and out of focus, and their ability to turn their eyes in and out. Along with this, we test color vision, depth perception and the health of their eyes ( both inside and outside ).
To be more specific, we are testing your child’s ability:
Ocular motor skills- eye movement skills:
Do your child’s eyes move across the page in a book smoothly and accurately.
Accommodation – eye focusing abilities:
Does your child change focus from near to far and back again – between reading text from a far-away white or black-board and then being able to write on a price of paper at their desk?
Convergence and Divergence- eye teaming:
Are your child’s eyes working together as a focus unit – do they come together for proper eye alignment for reading?
Binocular vision skills:
Are your child’s eyes blending visual images from both eyes into a single, three-dimensional image? If detected, these conditions can be corrected and managed. We often prescribe corrective lenses, progressives, prisms and vision therapy enabling young children with poor vision to rapidly catch up to their peers. The earlier a vision problem is diagnosed and treated, the less of an impact it will have on the child’s development, and the better the prognosis.
