4 Common Myopia Myths Debunked

4 Common Myopia Myths Debunked 640Myopia (nearsightedness) occurs when the eye elongates and rays of light entering the eye are focused in front of the light-sensitive retina rather than directly on it.

It’s by far the most common refractive error among children and young adults.

To help understand and learn more about what myopia means for your child’s vision, we’ve debunked 4 common myopia myths.

Myth: Myopia only develops in childhood

Fact: While it’s true that in most cases nearsightedness develops in childhood, it can also develop during one’s young adult years.

Myth: Wearing eyeglasses or contact lenses cause myopia to worsen

Fact: Prescription eyeglasses and contact lenses in no way exacerbate myopia. Optical corrections help you see comfortably and clearly. Another common misconception is that it’s better to use a weaker lens power than the one prescribed by your eye doctor. This is simply not true. By wearing a weaker lens you are contradicting the purpose of using corrective eyewear, which is to comfortably correct your vision.

Myth: Taking vitamins can cure myopia

Fact: Vitamins have been proven to slow the progression of or prevent some eye conditions, such as age-related macular degeneration (AMD) or cataracts. However, no vitamin has been shown to prevent or cure myopia. All vitamins and supplements should only be taken under the advice of your healthcare professional.

Myth: There is no way to slow the progression of myopia.

Fact: There are a few ways to slow down the progression of myopia:

Get more sunlight. Studies have shown that children who spend more time playing outdoors in the sunlight have slower myopia progression than children who are homebodies.

Take a break. Doing close work, such as spending an excessive amount of time looking at a digital screen, reading, and doing homework has been linked to myopia. Encouraging your child to take frequent breaks to focus on objects farther away can help. One well-known eye exercise is the 20-20-20 rule, where you take a 20-second break to view something 20 feet away every 20 minutes.

Other options to slow myopia progression include:

  • Orthokeratology/Ortho-k. These are specialized custom-fit contact lenses shown to decrease the rate of myopia progression through the gentle reshaping of the cornea when worn overnight.
  • Multifocal lenses offer clear vision at various focal distances. Studies show that wearing multifocal soft contact lenses or multifocal eyeglasses during the day can limit the progression of myopia compared to conventional single vision glasses or contact lenses.
  • Atropine drops. 1.0% atropine eye drops applied daily in one eye over a period of 2 years has shown to significantly reduce the progression of myopia

What You Should Know About Night Blindness

If you don’t see well while driving at night, there’s a chance you have night blindness. Night blindness, or nyctalopia, is the inability to see well at night or in dim lighting. It’s not considered an eye disease, but rather a symptom of an underlying problem.

Our eye doctor in Toronto can help diagnose, manage and treat your night blindness with specialized digital eye exams, so that you can enjoy being out and about at night again.

Here are 4 things you should know about night blindness:

Causes of Night Blindness

The inability to see well at night can be the result of a condition such as:

  • Vitamin A Deficiency — Vitamin A helps keep your cornea, the layer at the front of your eye, clear; it’s also an important component of rhodopsin, a protein that enables you to see in low light conditions. Although uncommon in North America, deficiency of this vitamin can induce night blindness.
  • CataractsA buildup of protein clouds the eye’s lens, leading to impaired vision, especially at night and in poor lighting conditions.
  • Diabetic RetinopathyDamage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.
  • GlaucomaThis group of eye diseases is associated with pressure build-up in the eye that damages the optic nerve. Both glaucoma and the medications used to treat it can cause night blindness.
  • MyopiaAlso called nearsightedness, myopia makes distant objects appear blurry, and patients with it describe a starburst effect around lights at night.
  • KeratoconusAn irregularly shaped cornea causes blurred vision and may involve sensitivity to light and glare which tend to be worse at night.
  • Retinitis Pigmentosa (RP)A progressive genetic eye disease which can be associated with other diseases, RP leads to night blindness and peripheral vision loss.
  • Usher SyndromeThis genetic condition causes both hearing loss and vision loss, including night blindness and RP, mentioned above.

Symptoms of Nyctalopia

Since night blindness is a symptom of some serious vision problems, it’s important to get your eyes checked regularly to ensure that everything is in good working order. Contact your eye doctor as soon as possible if you notice that you don’t see as well in dim light as you used to, such as when driving at night or when adjusting from being outdoors in the sunshine to being indoors.

Symptoms of Night Blindness Include:

  • Reduced contrast sensitivity
  • Difficulty seeing people outdoors at night
  • Difficulty seeing in places with dim lighting, like a movie theater
  • Trouble adapting to the dark while driving
  • Excessive squinting at night
  • Trouble adjusting from bright areas to darker ones

Treatments for Night Blindness

Your eye doctor will want to diagnose the cause of your night blindness in order to treat it. For example, in the rare case of vitamin A deficiency, it can be treated with vitamin supplements and vitamin-A rich foods; myopia can be corrected with eyeglasses or contact lenses. Other conditions may require medications or surgery.

If night blindness is caused by a birth defect, Usher syndrome, or retinitis pigmentosa, low vision aids and devices can help you make the most of your remaining vision.

Prevention

While there is no proven way to prevent night blindness resulting from genetic conditions or birth defects, consuming healthy, nourishing foods and taking certain vitamin supplements may prevent or slow the onset of some eye conditions that cause night blindness.

If you experience poor vision at night or in dim lighting, we can help. Contact Corktown Eyecare in Toronto to schedule your appointment today.

Frequently Asked Questions with Dr. Sanjay Vakani, O.D.

Q: Can you request lenses made from glass? Is glass still used for lenses?

  • A: Yes. Opticians still sometimes use glass for lenses. However, glass is not used very often because they aren’t as safe. If these glass lenses breaks, they can shatters into many pieces and can injure the eye. Glass lenses are much heavier than plastic lenses, so they can make your eyeglasses less comfortable to wear.

Q: Can a coating be added to eyeglasses to protect them from further scratches?

  • A: A protective coating can’t be added to a lens after it’s scratched. The coating is applied when the lens is manufactured and can’t be put on later.

Does The Use of Digital Devices Cause Myopia In Children?

kid with tablet 640Myopia (nearsightedness) occurs when the eyeball grows too long, or the cornea and/or eye lens are too curved relative to the length of the eyeball. This causes faraway objects to appear blurry. More than 30% of North Americans have this refractive error starting from childhood.

Being nearsighted isn’t just an inconvenience. Children with moderate to severe myopia are at significant risk of developing sight-threatening eye diseases later in life, such as glaucoma, cataracts, macular degeneration and retinal detachment.

But is there a link between spending too much time on digital devices and myopia? While digital devices keep our children busy and entertained, especially during the COVID-19 pandemic, it’s important to understand the implications associated with all this screen time.

What Does the Research Show?

There is growing evidence that up-close tasks raise the risk of myopia in children. In an analysis of 27 studies on 25,000 children published in the journal PLOS ONE, researchers found that the more time children spent on near-work activities like reading, homework, writing, computer use, playing video games, and watching TV, the higher their risk of developing myopia.

The analysis found that the odds of myopia increased by 2% for every hour per week a child did near-work activities.

Other studies have found that children who spend a significant amount of time playing outdoors experience less myopia progression than children who are homebodies. Researchers theorize that looking at distant objects, such as a ball flying through the air at the far end of a sports field, and sunshine play a role in myopia prevention.

Not surprisingly, most eye doctors recommend limiting the amount of time a child stares at a digital screen in order to safeguard their eye health and overall wellbeing. To learn more about myopia or to slow its progression, contact Corktown Eye Care Myopia Control Center today.

Frequently Asked Questions with Our Optometrists

Q: What Are the Signs of Myopia?

  • A: – Blurred vision: Using a digital screen for long periods of time can result in blurry vision, especially when focusing on distant objects.
    – Headaches: Untreated myopia can cause serious eye strain, which in turn results in headaches.
    – Head tilting or squinting: If you notice your child tilting their head while watching TV or squinting their eyes, it’s a sign that they are having difficulty focusing. This could be a sign of myopia.
    – Looking at objects a bit too closely: Oftentimes, children cannot verbally explain how they feel but they can express it in a non-verbal way. If you notice your child moving closer to the TV or that they have trouble seeing the blackboard at school, it can signal myopia.

Q: How Can I Prevent or Slow My Child’s Myopia?

  • A: Catching myopia early can help slow its progression and prevent serious eye diseases later in life. As a parent, here is what you can do to help prevent your child from developing this eye condition:
    – Try to limit the amount of time your child spends on close work such as reading, homework, and screen time.
    – When your child uses a computer, make sure they are properly positioned. Have your child take frequent screen breaks and look across the room for at least 20 seconds during each break.
    – Encourage outdoor time of at least 90 minutes a day, preferably in the sunshine. Be sure your child wears UV protected sunglasses.
    – Discuss myopia management with your eye doctor to slow and potentially stop the progression of your child’s myopia.


How We Can Help Treat Myopia

How Can My Child’s Myopia Be Corrected?

At Corktown Eyecare, we help children like yours achieve clear and comfortable vision, so they can succeed at the important things in life.

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. In some cases of very high myopia, contact lenses can offer clearer vision than glasses.

Corrective contact lenses are usually placed in the eyes upon waking and removed at night before bedtime. There are several types, including: soft contacts, daily disposables, extended wear, and rigid gas permeable (hard) lenses. Navigating through the differences between them can be daunting. Fortunately, if you’re located in Toronto our eye doctor will be happy to guide you. Speak with Dr. Vakani 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 fun and exciting! Allowing the children to be active participants in selecting their eyewear increases the likelihood that they’ll actually wear them. There are strong, flexible and resilient frames which look great and are comfortable too.

The optician can customize the lenses with additions and upgrades like impact-resistant or shatter-proof materials, scratch-resistant and anti-reflective coatings, UV filters, and transition lenses that darken in the sun. For those requiring vision correction for distance and near, we also offer bifocal or multifocal lens prescriptions.
