Myopia: The Dark Horse of Developing Visual Impairment 

by | Aug 29, 2024

From early bookworms to grade school top performers, from die-hard Star Trek fans to sports enthusiasts—many share a common challenge that has quietly grown in significance. Myopia, a condition often overlooked in the past, has become a major focus of eye care as scientists work to uncover its mysteries. Myopia is a developmental condition that typically begins in childhood and, if unmanaged, can cause permanent vision loss. With screens dominating our daily lives and academic pressures on the rise, myopia rates are increasing at an alarming rate, transforming a once rare condition into a global concern. Now more than ever, understanding myopia and intervening early is crucial for preserving long-term vision health. 

Defining Myopia

But what exactly is myopia? Myopia refers to a condition where the shape of the eye becomes elongated, altering how light passes through and focuses on the retina. This results in “nearsightedness,” where objects up close are clear, but those at a distance appear blurry. Myopia tends to progress rapidly in growing children, often slowing as they reach their late teens or early adulthood. Although current technology cannot reverse myopia, it can slow or even halt its progression. The cause is mainly unknown, but it has been tied to hereditary factors along with environmental and behavioral factors that are changeable. That’s why catching and beginning myopia management at a young age is crucial for preserving long-term vision health.

Early Symptoms of Myopia to Watch For

Identifying myopia in children is essential to minimizing its impact. Here are some signs to watch for, whether at school or at home:

School:

The first sign may be difficulty seeing from the middle or back of the classroom. Here’s how you can recognize if this might be an issue for your child:

  • Complains about not seeing the board clearly: Your child might voluntarily mention trouble seeing.
  • Loss of focus in class: Teachers may report behavior problems or note that your child is easily distracted.
  • Inconsistent performance: If your child’s grades are uneven, ask them where they sit in their lower-performing classes; difficulty seeing from the back may be a factor.

Another sign is after-school eye fatigue. You can recognize this if your child:

  • Complains of tired eyes: Your child might mention that their eyes feel strained, especially after school.
  • Experiences frequent headaches: Headaches can occur when the brain works harder to see at a distance.

Home:

At home, identifying signs of myopia should be a bit easier. Watch for:

  • Excessive blinking: This may be an attempt to see better at a distance.
  • Frequent eye rubbing: This could indicate vision discomfort, especially in younger children.
  • Squinting to see distant objects: If your child squints to identify objects far away, it might be a sign of myopia.
  • Sitting close to the TV or other screens: If your child consistently sits very close to the television or other screens, it might indicate trouble seeing from a distance.

If your child exhibits any of these symptoms, please schedule an eye exam with us as soon as possible. Early intervention with myopia management and proper vision care can help ensure your child enjoys healthy eyes into adulthood.

The Growing Concern of Pediatric Myopia

Roughly 42% of children in the U.S. are currently myopic, and studies project that over 50% of the global population will be myopic by 2050.2 Pediatric myopia not only affects daily life but also increases the risk of more serious vision health conditions, such as:

  • Macular degeneration
  • Retinal detachment
  • Glaucoma
  • Cataracts

If left unmanaged, these conditions can lead to partial or total loss of vision. Addressing myopia early is crucial to preventing these severe outcomes and ensuring long-term vision health. Please note that no amount of myopia is safe.

Harm Reduction Strategies for Myopia

While our understanding of myopia’s causes is still evolving, we know that certain behaviors can influence its progression. Two key behaviors to consider are near activities and far activities.

Near activities are those that require the eyes to focus on objects within arm’s reach or closer, and they are linked to the progression of myopia. To help reduce the risk, optometrists recommend limiting these activities when possible. Examples include:

  • Using screens such as phones, tablets, or computers
  • Reading books or e-readers
  • Writing or drawing

Far activities involve focusing on objects that are 20 feet or more away. Engaging in these activities can be beneficial, though it’s important to note that they don’t entirely prevent myopia. Examples of far activities include:

  • Playing outdoor sports
  • Hiking, biking, or picnicking
  • Leisure activities like flying kites or watching birds

By balancing near and far activities, and incorporating more outdoor play, we can help mitigate the progression of myopia and promote better eye health.

What is Myopia Management?

The goal of myopia management is to slow or even halt the progression of myopia, particularly during childhood and adolescence when the eyes are still developing. Effective management aims to encourage the eye to grow in a more optimal shape and prevent worsening vision.

Several evidence-based treatment options are available, including:

  • Ortho-K (orthokeratology): Nighttime contact lenses that reshape the cornea while you sleep, temporarily correcting vision for the following day.
  • Myopia control contact lenses: Specialized daytime lenses designed to slow myopia progression.
  • Prescription eye drops: Medication that can be used in conjunction with other treatments to manage myopia effectively.

At Beyond Eyecare, Dr. Khaldieh will work with you to determine the most suitable options for your myopia management plan, tailored to your individual needs.

Conclusion

Understanding and managing myopia is essential for long-term eye health. With myopia rates on the rise, early detection and intervention are more crucial than ever. Regular eye exams and proactive care can significantly reduce the risk of severe vision issues in the future.

If you’ve noticed any signs of myopia in your child or it’s time for a routine eye check-up, don’t delay. Schedule an appointment with us today to begin effective myopia management and safeguard your child’s vision.
