At the clinic, parents ask me almost daily: "Doctor, can my child wear Starry Control? What kind of children is Starry Control suitable for?"

Great question. Choosing the right lenses is just the first step in myopia management; the real key lies in understanding why to choose them, how to wear them, and how to manage their use afterward. Let's break it all down today.

I. The Answer: Which children are suitable for Star Control?

Stellest is a product launched by EssilorLuxottica in 2020.Myopia Control Multi-Focal Frame Lenses, the core function isSlow the progression of myopia in children and adolescents, not "cure myopia".

General Compatibility:

• Age: Children and adolescents aged 6～18 years (especially recommended for early-onset myopia in younger children aged 6～10 years, as this is the period of fastest axial length growth and the most critical intervention window)

• Myopia degree: -0.75D to -6.00D (75° to 600°)

• Cylinder: ≤ -2.00D (within 200 degrees)

• Wearing RequirementsRecommended daily wear time: ≥ 12 hours. Longer wear ensures more stable myopia control.

Ideal for high-risk children:

• High myopia in one or both parents indicates a clear genetic predisposition.

• Early onset of myopia (nearsightedness in early elementary school)

• Annual increase exceeds 50 degrees; progress is too rapid.

• Children who are not suitable for or unwilling to wear OK lenses (e.g., due to insufficient corneal conditions, young age, or poor compliance)

⚠️ The above is for reference only.Not an absolute standardEvery child has unique eye conditions, visual habits, and binocular vision functions. Whether they can wear corrective lenses and which type is most suitable must be determined by a qualified doctor or optometrist after a comprehensive evaluation.

II. Understand the Mechanism: How Does MyoCare "Control" Myopia?

To understand how MyoCare slows myopia progression, it's essential to first grasp how myopia develops.

The essence of myopia: elongation of the eyeball.

Our eyes are like precision cameras. Under normal conditions, light entering the eye is focused precisely onretinaOn, with clear and bright viewing.

However, if the anteroposterior diameter of the eyeball (i.e.,axial length) is "stretched," causing the focal point of light to fall on the retina.PreviousDistance becomes blurry — that's myopia.

More importantly:Focusing on central vision alone is not enough; the imaging state of the peripheral retina also influences axial length growth.

Traditional single-vision lenses correct only central vision, while peripheral light still focuses behind the retina (a phenomenon known as "peripheral hyperopic defocus"). This signal tells the eye to keep growing backward—explaining why some children's prescriptions continue to increase even when wearing regular glasses.

StarQuest Core Technology: H.A.L.T. High Aspheric Microlens

The secret of Stellest lies in the lens surface1021 microlensesThey are distributed across 11 star rings, adoptingH.A.L.T. (Highly Aspherical Lenslet Technology) High-Asphericity Microlens Technology。

These microlenses direct peripheral light onto the retinaAheadCreates a "myopic defocus signal band," which sends a "stop growing" signal to the eye, therebyInhibit excessive axial elongation。

Clinically supported:

• Compared to single-vision lenses, wearing glasses for ≥12 hours per day,Slows myopia progression by an average of 67%

• Reduces axial length growth by approximately 60%

• 2 years of clinical research shows: myopia progression reduced by 71%, axial elongation rate reduced by 53%

• No myopia rebound observed after discontinuing use; stable long-term management outcomes expected.

Released in 2025Stellest 2.0Equipped with an upgradedH.A.L.T. MAXTechnology enhances prevention and control efficacy. Mid-term data from 6 months show a 59% improvement in slowing axial elongation compared to the first generation.

3. Five Key Factors Influencing Myopia Progression

Before fitting myopia control lenses, you need to understand: Why does a child's nearsightedness worsen? Only by identifying the "culprit" can prevention be targeted and effective.

1. Genetic factors — innate "foundation"

If both parents are highly myopic, the child's risk of developing myopia increases significantly. Genetics affects not only "whether" myopia develops but also "how fast" it progresses—some children naturally have faster axial elongation rates than others.

But genetics is not destiny.Environmental interventions can still significantly slow progression and reduce the risk of developing high myopia.

2. Near-work load — the acquired "main driver"

The closer your eyes are to books, homework, or practice questions—and the longer you focus—the greater the strain on your eye's focusing system. This keeps your eye muscles tense and can lead to elongation of the eyeball.

Key Metrics:Reading at a distance less than 33cm or engaging in continuous close-up work for more than 40 minutes without a break are both high-risk behaviors.

3. Outdoor Activity Time — The Most "Cost-Effective" Prevention Strategy

Outdoor activities are currently widely recognizedMost effective, most secureprotective factors against myopia.

Principle:Outdoor natural light is significantly stronger than indoor light and promotes retinal secretion.DopamineHowever, dopamine can inhibit axial elongation of the eye.

Suggested Quantity:Daily cumulative outdoor activity≥2 hours, with a weekly cumulative total of ≥14 hours. Note that "outdoor" means outdoors—sitting by the window and getting sun does not count.

4. Electronics Usage — A Modern "New Threat"

Staring at screens for extended periods reduces blinking, leading to dry eyes and eye strain. Additionally, screen content is typically viewed up close with rapid transitions, increasing the accommodative demand.

Please note thatBlue light itself is not the primary cause of myopia.What matters most is the duration and posture of close-up work. Don't treat "blue light blocking" as the core strategy for myopia prevention.

5. Binocular Vision Function — The Overlooked "Invisible Driver"

Many parents focus only on prescription strength, overlooking binocular vision function.

If the child existsAccommodative insufficiency, convergence insufficiency, heterophoriaThese issues can lead to increased eye strain and faster progression of myopia. This is why, even among children wearing myopia control lenses, some achieve excellent results while others see only moderate improvement — underlying binocular vision disorders may be hindering progress.

IV. Scientific Strategy for Myopia Control in Children: More Than Just Glasses

Myopia management is a comprehensive approach, and lenses are just one component. Below are the currently recognized mainstream clinical interventions:

1. Step 1: Professional Medical Eye Exam — Don't Skip This

When a child develops myopia, the first step isn't "getting glasses," it's...Get a comprehensive eye exam。

A comprehensive pediatric eye exam should include:

• Dilated Eye Exam (to distinguish between true and pseudomyopia)

• Axial length measurement (the "gold standard" metric for tracking myopia progression)

• Keratometry, Corneal Topography

• Binocular Vision Assessment (Accommodation, Convergence, Fusion, etc.)

• Fundus examination (to rule out risks of fundus lesions in high myopia)

Why is it important?Only a comprehensive assessment can determine the most suitable prevention and control plan for your child, establish baseline data, and provide a reference for tracking progress.

2. Defocus Frame Lenses – Safe, Convenient, and Versatile

Multi-point defocus spectacle frames, such as the popular Xingqu Control model, are among the most mainstream approaches for myopia prevention and control.

Benefits:

• Fits like regular glasses, making it easy for children to accept.

• Non-contact with the eye, no infection risk, high safety

• Suitable for a wide age range (assessment available from 6 years old) and covers a broad spectrum of prescriptions

• Child-friendly for kids with dry eye, allergic conjunctivitis, and other conditions unsuitable for contact lenses

Note:For best results, wear them for at least 12 hours daily. The frame must stay stable and not slip; otherwise, the defocus effect will be compromised.

3. Orthokeratology (Ortho-K) lenses — Highly effective for myopia control, but requires eligibility screening

Ortho-K lenses are a type ofRigid Gas Permeable Contact LensesWorn overnight to temporarily reshape the cornea through physical molding, allowing clear vision during the day without glasses. It also generates peripheral defocus signals that help slow axial elongation.

Suitable for:Children aged 8 and above, with myopia up to 600 degrees, qualified corneal conditions, good hygiene habits, and high compliance from both parents and children.

Reminder:Orthokeratology lenses belong toClass III Medical DeviceMust be fitted at a licensed eye care facility. Follow all care and follow-up instructions strictly. Do not purchase online or have it fitted at non-medical facilities.

4. Low-dose Atropine — An Adjunct to Pharmacological Intervention

0.01%–0.05% low-concentration atropine eye drops, a widely used clinical intervention for myopia control, work by relaxing the ciliary muscle and inhibiting axial elongation to slow myopia progression.

Commonly used for children with rapid myopia progression. Can be used alone or in combination with optical interventions (orthokeratology lenses / defocus spectacle lenses).Use only under the guidance of a healthcare professionalCannot be purchased independently.

5. Behavior Management — The Foundation

Even the best lenses can't withstand the wear and tear of bad habits.

• Reading and Writing Posture:Keep your eyes at least one foot (about 33 cm) from the book, your chest one fist away from the desk, and your hand one inch from the pen tip.

• 20-20-20 Rule:After 20 minutes of near-eye work, look at an object 20 feet (approximately 6 meters) away for 20 seconds.

• Outdoor Activities:More than 2 hours daily—aim for as much as possible.

• Lighting:Ensure adequate lighting when reading or writing. Avoid using your eyes in dim or unstable environments.

6. Regular Follow-ups — Adjust as needed; fitting isn't a one-time task.

Myopia prevention and control isDynamic Managementis just the beginning, not a one-time fix after getting glasses.

Suggested review frequency:Follow-up every 3–6 monthsReview Content:Visual acuity, refractive error, axial length, corneal status (for children wearing orthokeratology lenses), and lens/frame condition.

Why check axial length?Refractive power can fluctuate due to various influencing factors, andAxial length is the most objective indicator for monitoring myopia progression.Skipping axial length measurement means you've only done half the job in managing myopia.

5. The 5 Most Common Pitfalls Parents Fall Into

❌ Myth 1: "Don't get glasses yet—you'll be stuck wearing them once you start."

Truth:Once true myopia develops, the prescription will not decrease on its own. Not wearing glasses leaves the eyes in a persistently blurred state, which can increase eye strain and cause the prescription to worsen faster. Failing to wear them when needed is truly harmful to your child.

❌ Pitfall 2: "Focus only on brand, ignore fitting"

Many parents immediately ask, "Which brand is the best?" while overlookingProfessional FittingandSubsequent tracking and management。

The effectiveness of myopia control lenses = lens technology × precise fitting × wearing compliance × behavior management. Even the most reputable brand delivers suboptimal results if the fitting is inaccurate, the glasses are worn incorrectly, or habits aren't changed.

❌ Myth 3: "Wearing myopia-control glasses makes everything fine."

Control lenses are not a "safe deposit box." If a child spends 6 hours daily on near-work, has insufficient outdoor time at 0, and wears glasses inconsistently, even the best lenses cannot prevent myopia progression.

❌ Myth 4: "Worsening vision means myopia is getting worse."

Fluctuations in vision don't always mean your prescription has changed. They could also be caused by eye strain, accommodative spasm, or lens wear.To assess myopia progression, check axial length and cycloplegic refraction; relying solely on uncorrected visual acuity is insufficient.

❌ Pitfall 5: "Wait until the prescription is high before getting good glasses."

The golden window for myopia prevention and control isWhen myopia first occurs and the prescription is still lowThe earlier you intervene, the better you can keep prescription levels low and reduce the risk of progressing to high myopia. It is much harder to "catch up" once prescriptions have already increased.

VI. A Few Final Words from the Heart

In routine outpatient visits, I find that most parents are most concerned with "which lens brand to choose," but what truly determines the trajectory of a child's myopia is oftenEye habits, visual function, and long-term management。

MiyoSmart-type defocus lenses are an effective tool for controlling myopia progression in eligible children. However, they are not a "miracle cure" nor a one-time solution.

Managing myopia in children is not solved by a single pair of glasses; it requires a multi-year, systematic approach.

As a parent, the three most important things you can do are:

1. Early detection—— Schedule regular eye exams; don't wait until your child says, "I can't see clearly."

2. Choose the right solution—— Consult a professional agency for a comprehensive evaluation and choose the best fit based on your child's specific needs.

3. Maintain ManagementEye exams, follow-ups, outdoor activities, and healthy viewing habits—don't skip any.

May every child enjoy clear vision and a future unbound by glasses.
