Myopia, commonly known as nearsightedness, is a prevalent eye condition that affects millions of children worldwide. Understanding myopia is crucial for parents to ensure their children's visual health and overall development. In this comprehensive guide, we will break down the basics of myopia, explore its causes, and discuss how it affects children's vision. Most importantly, we'll provide actionable tips for parents to identify early signs of myopia in their children and steps they can take to manage it effectively.

At Rainbow Optics in Eugene, we offer pediatric eye exams to screen children for eye problems like myopia. These eye exams allow us to provide solutions like myopia management to manage its progression effectively.

What is Myopia?

Myopia is a refractive error characterized by blurry distance vision and clear up-close vision. Myopia occurs when light entering the eye focuses in front of the retina instead of directly on it. As a result, the images are formed in front of the retina, leading to blurred distance vision.

This eye condition often begins during childhood and adolescence and stabilizes during early adulthood.

Causes of Myopia in Children

Understanding the causes of myopia can help parents take preventive measures. While the exact cause remains under research, several factors contribute to the development of myopia in children:

  • Genetics: If one or both parents are nearsighted, their children are at a higher risk of developing the condition.
  • Environmental Factors: Prolonged near-work activities such as reading, using digital devices, and studying can increase the risk of myopia.
  • Lack of Outdoor Time: Insufficient outdoor exposure, especially during childhood, has been linked to higher myopia rates.
  • Poor Lighting and Reading Habits: Inadequate lighting while reading or engaging in close-up tasks can strain the eyes and contribute to myopia.
  • Ethnicity: Certain ethnic groups have a higher genetic predisposition to myopia.

How Myopia Affects Children's Vision

While blurry vision is a hallmark of myopia, its consequences go beyond how your child can see. If left untreated, myopia can lead to issues, including eye strain, headaches, and difficulties in school. Additionally, myopia progression increases the risk of more severe eye conditions later in life, such as retinal detachment, glaucoma, and macular degeneration.

Identifying Early Signs of Myopia

Being vigilant about your child's visual health is essential. Watch out for signs like squinting, sitting too close to screens or books, rubbing eyes frequently, and complaints about headaches or eye discomfort. If you notice these signs, it's time for a comprehensive pediatric eye exam.

Steps to Manage Myopia in Children

Early intervention is crucial in managing myopia effectively. Here are actionable steps you can take as a parent:

  • Schedule Regular Eye Exams: Schedule comprehensive eye exams for your child, even if they don't display any symptoms of myopia or eye problems. Routine eye exams can identify myopia and other potential vision issues in their earliest stages, allowing the eye doctor to prescribe glasses, contacts, or myopia control strategies such as atropine eye drops, multifocal contacts, and orthokeratology lenses.
  • Promote Outdoor Time: Encourage outdoor activities, as studies suggest that spending time outdoors can help reduce the risk of myopia progression.
  • Limit Screen Time: Monitor screen time and ensure proper lighting and comfortable seating when your child engages in near-work activities.

Myopia Management Techniques at Rainbow Optics

Orthokeratology (Ortho-K)

Orthokeratology, or ortho-k, is a non-surgical myopia control method that uses the power of rigid gas permeable (RGP) contact lenses to reshape the cornea overnight. Ortho-k lenses, made from gas permeable materials, allow oxygen to reach the cornea even as they correct its shape. When your child removes the lenses after waking up, they will experience clearer vision throughout the day without needing glasses or contacts.

Additionally, ortho-k offers practical advantages that align with the active lifestyles of children and adolescents. Not relying on glasses or contacts during the day is advantageous for children who engage in sports and outdoor activities or want to experience the freedom of unrestricted vision.

Not only does ortho-k enhance visual acuity, but it also plays a role in slowing down the progression of myopia. Ortho-k reduces the excessive focusing of light that contributes to the elongation of the eyeball by gently flattening the central area of the cornea.

Atropine Eye Drops

When administered in low doses, these drops work by temporarily relaxing the eye's focusing mechanism, thereby slowing down the elongation of the eyeball that causes myopia. This intervention preserves clarity and reduces the risks of more severe eye conditions caused by high myopia.

Multifocal Contact Lenses: Balancing Clarity at All Distances

Multifocal contact lenses feature different prescription zones across the lens, providing clear vision for both near and distant objects. This balanced visual experience encourages the eye to adapt to various focal points, which reduces eye strain that triggers the eyeball’s elongation.
