MYOPIA MANAGEMENT

What is Myopia?

Myopia, also known as nearsightedness, is a refractive error of the eye that affects how light is focused. People with myopia can see nearby objects clearly, but distant objects appear blurry. This occurs when the eyeball is slightly longer than normal or when the cornea has excessive curvature. As a result, light entering the eye focuses in front of the retina, leading to blurred distance vision. Myopia management is essential to ensure this condition doesn’t worsen over time.

How do I Know My Child has Myopia?

Detecting myopia in children can sometimes be challenging, as they may not always recognize or communicate vision changes. However, there are signs and behaviours that could indicate the presence of myopia.

Squinting
Sitting Close to Screens
Holding Books Closely
Complaints of Blurriness
Trouble Seeing Classroom Boards
Changes in School Performance
Family History: The likelihood of developing myopia increases 50% when both parents are myopic, 33% when one parent is myopic, and 25% if neither parent is myopic.

Even if you don't notice any specific signs, it's important for children to have regular eye exams. An optometrist can detect myopia during a comprehensive eye examination, even if there are no obvious symptoms. In some cases, MiyoSmart lenses, MiSight lenses, or Atropine Drops might be recommended as part of a tailored treatment plan.

Why is Myopia a Concern?

Myopia is on the rise in North America, affecting about 42% of people in the U.S. Its prevalence is increasing, and 50% of the world's population is projected to be myopic by 2050. Myopia isn't just about needing glasses or contact lenses to see clearly; it's also associated with potential eye health risks. High levels of myopia can increase the risk of sight-threatening conditions such as retinal detachment, glaucoma, and macular degeneration. Taking steps to manage and control myopia can reduce the likelihood of these complications.

When Does Myopia Progression Occur?

Myopia progression typically occurs most rapidly during childhood and adolescence, particularly between the ages of 6 and 17. The early teenage years, around 12 to 16 years old, often see the fastest rate of myopia progression. However, it's important to note that myopia progression can vary among individuals, and factors such as genetics, environmental influences (like screen time and outdoor activities), and overall eye health play a role in the rate of progression. Regular eye exams and myopia management strategies, including the use of myopia treatment lenses, during these critical years can help slow down the progression and reduce the associated risks.

Taking Control: Treating Myopia

Fortunately, there are several options available to treat myopia and slow down its progression. Our clinic offers a range of evidence-based approaches tailored to each individual's needs:

Orthokeratology (Ortho-K): This non-invasive technique involves wearing FDA approved specialized gas-permeable contact lenses overnight. These lenses gently reshape the cornea, providing clear vision during the day without the need for glasses or contacts. This is a highly effective form of myopia control, particularly beneficial for children.
Atropine Drops: Prescription atropine eye drops can help relax the eye's focusing mechanism, slowing myopia progression. Atropine treatment can be combined with other myopia management methods for enhanced effectiveness, offering a more comprehensive approach to slowing myopia progression.
Multifocal Contact Lenses/Dual Focus Contact Lenses (MiSight, Ability): These contact lenses have different prescriptions in different zones, allowing for clear vision at various distances. Children and teenagers often adapt well to wearing contact lenses. This is especially beneficial for activities such as sports and other outdoor pursuits.
Spectacle Treatment Lenses (MiyoSmart): These treatment lenses are used to help manage myopia progression by using a technology called ‘defocus incorporated multiple segments (DIMS). The lens has multiple zones with different powers so that light enters the eye through these different zones and creates a controlled defocus on the peripheral retina, which has been shown to slow down the progression of myopia. This option is ideal for those who prefer traditional glasses and want an effective myopia treatment lens.

The Goal of Myopia Management: Clear Vision, Healthy Eyes

The primary goal of myopia management is to slow down the progression of myopia. By doing so, we aim to achieve two crucial outcomes:

Clear Vision: We want to ensure that individuals with myopia continue to enjoy clear and comfortable vision for their daily activities, without the constant need for stronger glasses or contact lens prescriptions.
Reduced Future Risks: Myopia management is also about safeguarding long-term eye health. Slowing down myopia progression can help lower the risk of potentially sight-threatening conditions associated with high levels of myopia, such as retinal detachment, glaucoma, and macular degeneration.

Treatment Duration: Individualized Approach

The duration of myopia management treatment varies from person to person. It typically depends on factors such as the severity of myopia, the chosen management method, and how well the individual responds to the treatment.

In many cases, significant progress can be observed within the first 6 to 12 months of consistent myopia management. However, myopia management is an ongoing process, especially for children and teenagers, as their eyes are still developing. Continuous monitoring and adjustments may be necessary as the individual's needs evolve over time.

It's important to understand that myopia management is not a one-size-fits-all approach. Dr. Fong will work closely with you or your child to create a personalized treatment plan tailored to your specific circumstances and lifestyle. Regular follow-up appointments allow us to track progress and make any necessary changes to ensure the best possible outcomes.

Good Habits To Slow Down Myopia Progression

The Importance of 2 Hours of Outdoor Activity:

Natural Light Exposure: Spending time outdoors exposes your eyes to natural sunlight. Natural light is significantly brighter than indoor lighting and contains a balanced spectrum of colors. This exposure helps in regulating the growth of the eye and plays a vital role in myopia control. Studies suggest that children who spend more time outdoors have a lower risk of developing myopia or experience slower myopia progression.
Increased Distance Vision: Outdoor activities typically involve looking at objects and scenes at various distances, which exercises your distance vision. This contrast to prolonged near work (such as reading or using digital screens) reduces the strain on the eye's focusing mechanism and helps in maintaining a healthy balance between near and distance vision.
Reduced Screen Time: Spending time outdoors naturally limits the amount of time spent on digital devices and other near tasks, which is known to contribute to myopia development. By engaging in outdoor activities, individuals tend to reduce their screen time, leading to better overall eye health.

The 20/20/20 Rule:

The 20/20/20 rule is a simple technique to alleviate eye strain and reduce the risk of myopia progression, especially during prolonged periods of near work:

Every 20 minutes, take a 20-second break.
During the break, focus on an object at least 20 feet away.

This rule reminds individuals to give their eyes a regular break from the constant strain of near vision tasks, promoting better visual comfort and reducing the risk of myopia development or progression.

The Elbow Rule:

The Elbow Rule is another practical technique to maintain a healthy working distance from screens and books:

Keep your digital devices, books, or other near work materials at least an arm's length away from your eyes.

This rule encourages a comfortable working distance that reduces the stress on your eyes' focusing muscles, thereby reducing the risk of myopia progression.
