Introduction
In general, myopia may continue to progress after age 15. Since the patient is under 18 years old and still in the growth and development stage, myopia progression is common—many adolescents aged 15 still experience worsening refractive error, and some individuals even continue to progress until age 18 or beyond. Typically, myopia stabilizes around age 20.

Increasing numbers of people are developing eye disorders nowadays, with myopia (nearsightedness) being one of the most common. In daily life, individuals should take good care of their overall health—especially those who spend long hours staring at smartphones and computers, and particularly adolescents, who require special attention. So, does myopia continue to progress after age 15?

Does myopia continue to progress after age 15?

In most cases, yes—myopia can still progress after age 15. Since patients under age 18 remain in an active phase of growth and development, myopia often continues to worsen during adolescence. Some individuals may even experience progression up to age 18 or beyond, and refractive stability is typically not achieved until around age 20. Therefore, myopia in 15-year-olds may still increase significantly. In daily life, it is essential to adopt healthy visual habits: avoid prolonged use of smartphones, computers, televisions, or video games; refrain from staying up late; and minimize extended periods of near-work. Patients are encouraged to engage in regular outdoor activities and practice proper eye hygiene—for example, taking a 20-minute break every 40 minutes of study to rest the eyes by gazing at distant greenery, thereby promoting healthy and appropriate visual habits.

After age 18, myopia generally stabilizes for most individuals. In adulthood, refractive error usually ceases to progress annually and remains relatively constant. However, some adults may retain mild or moderate myopia. Whether myopia progresses further in adulthood varies among individuals, but in general, progression is uncommon. Regular follow-up examinations—including automated refraction—at least every two years are recommended to monitor whether myopia is still increasing. If no progression is observed, this may indicate eligibility for refractive surgery.

Patients are advised to maintain correct posture while studying, avoid reading or studying in dim lighting or suboptimal environments, ensure adequate sleep, and engage in at least two hours of outdoor activity daily. We hope this information proves helpful.

What does vision 4.5 correspond to?
Visual acuity of 4.5 on the logarithmic visual chart corresponds to 0.3 on the decimal visual chart, indicating insufficient clarity when viewing distant objects. This may result in blurred or double vision when looking at faraway items. In daily life, one might need to move closer to see things like blackboards or road signs clearly. This condition is commonly associated with refractive errors such as myopia or astigmatism.

What should I do if my nearsightedness suddenly worsens?
If nearsightedness suddenly worsens, it is important to promptly undergo an eye examination to reassess vision, rule out eye diseases, adjust visual habits, improve the visual environment, and supplement nutrients beneficial for eye health, so as to avoid delaying diagnosis and treatment of potential problems. If accompanied by symptoms such as eye pain, distorted vision, light sensitivity, or excessive tearing, immediate medical evaluation is recommended. A professional eye exam can accurately determine changes in myopia degree and distinguish between true myopia and pseudo-myopia.

How to Get Rid of Myopia Glasses
To get rid of myopic glasses, common methods include laser surgery, implantable intraocular lenses, orthokeratology (corneal reshaping lenses), vision training, and controlling the progression of myopia. Eligible individuals may choose laser surgeries such as SMILE or LASIK, which adjust the corneal shape to correct refractive errors, allowing light to focus accurately on the retina. After surgery, clear vision can be achieved without the need for glasses.

What is 500-degree myopia in terms of decimal visual acuity?
If an individual has strong accommodative ability of the eyes, even with 500 degrees of myopia, they may achieve around 0.2 visual acuity during a standard eye chart test by relying on the eye's natural accommodation, barely recognizing the larger optotypes on the chart. However, distant details still appear blurry, and prolonged visual tasks can easily cause eye strain. Therefore, they still need corrective devices to improve their vision.

What is the highest degree of myopia?
From the perspective of common clinical classifications, myopia exceeding 600 degrees is considered high myopia, and over 1200 degrees is classified as very high myopia. Although these conditions are relatively rare in the general population, the number of individuals with high myopia has been gradually increasing due to changes in eye usage habits. Most patients with high myopia can maintain normal daily lives through appropriate correction, provided that no severe structural abnormalities have developed in the eye.

How to recover from myopia in children's eyes
Children's myopia cannot be reversed. The key to improvement lies in controlling the progression of myopia, which can be achieved through scientifically prescribed eyeglasses, developing good eye-use habits, increasing outdoor activities, performing standardized eye exercises, and adjusting dietary patterns. These interventions help prevent myopia from progressing to high myopia. If you notice symptoms such as blurred vision or squinting in your child, it is recommended to seek timely medical evaluation and refraction testing.

How to restore normal vision for right eye myopia
Methods that may help improve or control myopia in the right eye generally include scientifically wearing corrective glasses, using orthokeratology lenses, performing regular eye relaxation exercises, adjusting visual habits, and conducting routine vision monitoring. Scientifically wearing corrective glasses: Obtain a professional eye examination at a qualified institution to determine the accurate prescription, and select appropriate single-vision or progressive multifocal glasses to correct refractive errors, ensuring clear vision and preventing myopia progression caused by blurred eyesight.

Is eye massage helpful for myopia?
For individuals with myopia who experience eye fatigue symptoms such as eye pressure, dryness, and soreness due to prolonged near-work, gently massaging acupoints around the eyes (such as the temples and Jingming points) can promote blood circulation in the eyes, relax the surrounding muscles, alleviate fatigue, and provide temporary comfort. This may help prevent further indirect impact on vision caused by worsening eye strain, but it cannot alter the structure of the eyeball or reduce the degree of myopia.
